"British Jane's Defence , " the latest list published in the world armed helicopters :

-50/52 cards first to Russia because of the world's first single helicopter , tied for the cockpit cabin , the pilot escape system, the world needs innovation.

The second U.S. AH-64D, a strong fire , stunning battle effects .

The third Russian -meter -28N, the descendants of the devil fighting vehicles , AH-64 design ideas with the same inherited good genes m -24 , but the actual results to be tested .

Chinese Wu fourth straight 10 , a strong fire and integrated combat capability, better fire control systems, combat and a half Jing big and strong survival advantage , but also the development of which should be able to surpass his idol , " Tiger . "

Fifth Tiger helicopter , multi-country research, stumbling , can be considered an international armed helicopter.

Sixth Italian A-129, an independent development of the spirit is admirable , much like Italian opera , a little " look beautiful "feeling .

Seventh place in South Africa " kestrel "helicopter , the uncontested top dog , a product of modern Africa , for a long time not played him the other helicopters , but it is worth everyone's attention , at least 10 study arms straight over his experience .

Eighth AH-1W, very old helicopter safety and the relatively new device , the whole be antiques , and the next ten straight opponents arms , arms straight face difficult re- energized the 10 .

Ninth m -24 , as the war in Afghanistan was guerrilla fighting vehicles known as the devil , and now the world's large holdings , we will go further in future local wars amazing role to play .

The Chinese Z-10 armed helicopters to sources , the project is still sound manner, the Western suppliers make this project possible. Changhe Aircraft Industries, Inc. has delivered three prototypes , two of which are believed to ongoing flight test .

One said to the Chinese at Xi'an Yanliang Flight Research Institute (CFTE) flight testing , which is located in northwest Shaanxi Province . Two or more said that the PLA Army Aviation Bureau in Jingdezhen Equipment Department , which is located in northern Jiangxi Province .
The news from Beijing , Z-10 test team so far with the new helicopter flying more than 400 hours . The latest pictures show , it is possible the 3 Z-10 uses JDW early prototype design .
Clearly shows that Z-10 rotor system with 5 leaves , with distinctive clockwise direction . Presumably, China has adopted the European technical support systems and Agusta rotor gear box and transmission authorization .
The new scissors -type tail rotor and tail layout at first sight can clearly see , Z-10 with the latest developments in machine gun under the nose with a short wing weapons pylons . Temporary flight test equipment and data sensors installed in the aircraft nose .
Wire shear reactor protection system installed in tandem two-seat cockpit above . Tail black body coated with PLA markings.
In China , Z-10 is often called the WZ-10. Equipment from the West without any special export license , based on China 's medium-sized helicopter (CMH) program under the guise of marketing .
CMH commercial design work still in progress, a number of Z-10 design and CMH is shared, but the Z-10 is much advanced than the CMH .
And the Sukhoi Su-27 / Shenyang J-11 , as China is pushing forward China-made Z-10/CMH process , the key import item - an important engine - will eventually be replaced by local production facilities .
However , WZ-9 ( vortex axis -9), Z-10 's specified engine , has been developed for several years and is behind schedule . Z-10 engine supplier Pratt & Whitney Canada is ready for the next batch of PT6-67C turboshaft engines delivered 10 sets of engines have been delivered to China . The helicopters are equipped with weapons, combat tasks for the implementation of the development of the helicopter . The early 60s , the United States in the Vietnam War, extensive use of helicopters (mostly transport type) . War, the helicopter suffered heavy losses , and therefore decided to develop dedicated helicopter gunships. The first helicopters designed in the United States of AH-1 " Cobra " , 1967, to equip our troops and for the Vietnam war . Made some of combat effectiveness . Then 80 years of local wars , armed helicopters appeared again in the Iran-Iraq war, armed helicopters appeared in the first duel , m -24 in the AH-1 air combat , the development of the armed helicopter into a new era.

In the 91 years after the Gulf War , armed helicopters, is shine . Regard the development of military power the world armed helicopters, as the increased firepower of the revolutionary army weapons . I have not seen any fighter rankings , have not seen the list of armed helicopters . So, today the mainstream of world development of armed helicopters to make a simple comparison of their products integrated combat water to make a ranking for the majority of fans to discuss the military ! Also be the world's first person military fans now! ( low- low profile )

At present, the armed helicopters can be divided into specific types and multi -use two broad categories. Dedicated machines shot long and narrow , operational capability; multi -use addition to the task can be used to carry out attacks can be used for transportation, air-landing missions. Such as the U.S. AH-1 is in a private type , and the former Soviet Union are over -use meters -24 .

Today, we evaluate the armed helicopters are the U.S. AH-64, AH-1, Russia's card -50/52 , m -28 , m -24 helicopter , the Tiger helicopter in Europe , South Africa, " kestrel "helicopter , Italian A-129 helicopters , as well as the legendary Chinese WZ-10 helicopter . Performance of the various armed helicopters , I am not to list , mainly from the armed helicopter performance in all aspects of comparison , listed in 2006 , " Division 's Defense Weekly " armed helicopters in the world rankings .

We mainly from the following aspects of the armed helicopter to compare :

1 . Aircraft structural layout

2 . Maximum speed and climb rate ( sea level )

3 . Bullet-proof and anti- crash performance

4 . Airborne fire and payload

5 . Airborne equipment and machine performance

6 . Stealth Performance Comparison (anti- radar stealth performance and IR thermal radiation control) aircraft structural layout

Most are single- rotor helicopters aerodynamic layout , with narrow face , thin body structure and layout , to minimize the size of the outline of helicopters . -50/52 cards in this area really is the world's original , especially the structure of the most outstanding design card -52 . Cards -52 of the most striking features is the adoption of parallel two-seat cockpit layout , but the traditional two-seater helicopters are for the serial layout . It adopts two-seat layout was not tied maverick , which is the modern armed helicopters and the driving need to undertake design and development of combat tasks . First, the card -52 for all-weather , all-time altitude designed to attack ground targets .

-52 cards tied with a unique two-seat layout

U.S. Sikorsky Aircraft Corporation had tried to do something about , but later forced to give up . Today, the Kamov Design Bureau, the layout of a helicopter rotor in this still means the only world , the West can only be developed unmanned helicopter this layout . Second , as early as 1972, the United States in implementing the AH-1 " Huey Cobra " serial -type two-seater helicopters plan layout night , they reached the same conclusion : the best use of crew members tied for the layout . Therefore, the card layout is not a two-seater helicopter -52 back , but by using a rational design needs , is an armed helicopter cockpit layout to create . Two parallel two-seat advantage is to share some of the instruments , equipment, thereby simplifying the operation of the device working , so the driver can concentrate on tracking targets , and minimizing the time a decision . K50 was a bit ace test pilot died in the two- card -50 rotor when flying in high- mobility two- rotor collision accident , and later improved rotor design strength , to avoid such accidents. However , the world armed helicopter designer or design of such reservations . But this arrangement is suitable for use on naval vessels , to save the limited space on board .

Maximum speed and climb rate ( sea level )

Tiger helicopter to reach a maximum speed of 340 km, the maximum climb rate of 12.5 m / s , these indicators very high , while the AH-64D 's maximum speed of 293 km, the maximum climb rate of 7.5 m / sec. To achieve these properties , Apache 10% to lose weight . -50/52 this card is also very good , if, as air combat helicopter , the card -50/52 mobility is the best !

Other helicopters basic also in this level , it is said Takenao 10 using a Canadian HP PT6C-67C engine , so guess if the motor level and Tiger helicopters and the Italian A-129 helicopter at the same level , than the AH-64D and AH-1W Better mobility . The development objective of anti-tank and anti- helicopter operations will be on the same level , so Takenao 10 Tiger helicopters should be basically the same level.

Bullet-proof and anti- crash performance

In this regard , AH-64 Apache and Mi -28 performance is the best. This is because the initial request for close fire support helicopters , m -24 lessons on the battlefield in Afghanistan after the design. AH-64 using fiberglass reinforced stainless steel multi- beam anterior and apply to glass fiber reinforced plastic skin of the honeycomb core of the design , by firing proved that the rotor blades any point in the 12.7-mm guns were hit , the general Not cause structural damage , can continue their mission . Body using the traditional skin - bulkheads - Long Yan structure, 95% of the surface of any part had been shot with 23 mm shell hit , it can still ensure continued flying for 30 minutes. Both before and after the cockpit armor , can withstand 23 mm artillery attacks. Two key parts of the engine also has armor protection , and the middle of the fuselage separated , the two far apart .

Russia meters -28 helicopters has excellent protection capability

M -28A very stressed protection, m -28A on the protective ability of the unusual . M -28A cockpit fitted with titanium armor . -50 with the card , like the glass cockpit , cabin , 50 mm thick glass to withstand 12.7 mm bullets and 20 mm artillery shells fragments blow. M -28A engine can withstand a few rounds of attacks . M -28A of the fuel tank is located in the central body . Explosion inside the tank is installed polyurethane material to prevent static electricity and fuel rock explosion , the surface is coated with latex since closed . Fuel system can work under negative pressure conditions , Yi Fang Zhi fuel tank and fuel tubing to be penetrated by flying to the body surface when the fire exploded , and ensure that the helicopter a short time overload situations of negative normal take-off . Rotor blades have filaments of glass fiber wrapped protection . These measures make rice -28A became the world's only an all- armored helicopter gunships.

Other armed helicopters, caused basically due weight composite armor protection for key positions . I think the straight 10 protective force should be very good , Beihang Feng composite ballistic flight as there are seats cup works well on a composite armor by the end of the world , especially ceramic armor , they made a great breakthrough , can prevent the most deadly 12.7mm armor-piercing incendiary attacks on the engine . Arms straight in this respect of not less than 10 , the level of the Tiger helicopter .

Airborne fire and payload

This is definitely dominated by heavy-duty helicopters . AH-64 and -28 m of the payload are , according to the forefront , which is equipped with Hellfire missiles, Apache is the best tank killer . But m -28 can carry a total of 32 radio -guided AT-6 anti-tank missiles , slightly better than Apache . Other armed helicopters, is basically about Hawk can carry eight or similar missile , can carry a portable air missiles .

Basically, countries have fixed the cannon armed helicopters , caliber 30-23-20 mm. Beijing 2005 defense exhibition has been displayed 23MM helicopter with machine gun, and the domestic media have reported the overall domestic 30mm off shell , its armor-piercing levels than the U.S. A-10 equipped with the 30mm depleted uranium penetrators , this force should be good straight 10 . Direct exposure of the upper 10 's cannon is considerable scope Yang shows us the designer 's emphasis on helicopter air combat .

AH-64 's standard equipment is 30mmM230 " serpent " , to breakdown the top of the existing tanks, armor and side armor. AH64 tank design requirements early rally higher , wear Bomb lower muzzle velocity , then it would be difficult to fight tanks , another reason for ammunition , the same caliber gun recoil products larger than the Westerner , contrast, anti-tank needs Westerner is not high .

Tiger 's cannon of the Yang Ke Yi You a great perspective , if Zhi Kaolv ground attack , then , does not seem so big in the elevation necessary , then Zhiyou one explain comparative Heli , Tiger Yanzhizhichu on the Yi Jing to the helicopter 's air combat between Made adaptive design. Generally low level of air supremacy that the theater is still up to the helicopter to fight better , Tiger has an advantage compared with AH64 . A-129 helicopters , equipped with the 20mm Gatling rotary cannon , armor-piercing capability is weak , but the high rate of fire , and the big gun shooting range , which is the advantage of A-129 equipment .

Relatively weak in this regard is the card -50/52 , mainly aircraft and layout constraints, parallel layout limits the pilot vision , and the head of the design can not be installed on the larger cannon shooting angle , and only with the body on the right to install The gun , a small design perspective . This is the card -50/52 can not be accepted in some countries one of the reasons .

China's Wu straight 10 will be equipped with the world's first dedicated air missiles TY-90, which is not good news for Apache , arms straight 10 in this regard is a world leader . Wu will also be equipped with laser-guided direct 10 new HJ-10 laser-guided missiles , integrated system of operational effectiveness is not weaker than the U.S. Hellfire .

Airborne equipment and machine performance

In this regard, ahead of other countries, Apache helicopters, " Apache " head cylindrical object is the target acquisition / identification system (TADS) and Pilot Night Vision System (PNVS) and so on . Including a string of high-resolution TV , a " direct vision optical device " telescope system , automatic tracking device and laser spot tracking device .

AH-64D equipped with millimeter-wave radar, named LONGBOW " Longbow ", which can pass through bad atmospheric radar , airborne infrared equipment was found not disguise found mixed in the ground he 's objectives and target detection by And classification of equipment to target the radar probe signal characteristics and comparison of data from the database , in order of priority set out on the machine 's threat level . " Longbow "radar with a variety of works, open space way that can detect aerial targets , but could not be detected in the empty way of ground targets . An equipment " Longbow "radar for the attack helicopter squadron to provide air alert . " Longbow "radar also has terrain following capability , this way normal pilot 's night vision equipment and in the night-vision goggles (NVG) to the case of bad use .

Tiger helicopter equipment EuroGrid digital mapping system to display color topography topographic maps , and as a helicopter flight while mobile . The system is designed for "Tiger "design , in two separate multi-function display shows different proportions of topographic maps , maps marked with landscape information . Digital mapping system also with other aircraft, ground vehicles and include the development of combat missions , including ground stations connected .

A-129 type with two independent international infrared night vision system that uses a head mounted display , making night and under bad weather to improve combat effectiveness . Machine to install a sound digital integrated control systems, flight and combat missions managed subsystems . Weapons systems have been greatly improved . Use of low noise LHTEC-T800 engines , the same but with two separate oil supply system connected to each other . Installation of the ELT-156 radar warning device and the ALM-10 laser warning devices , and AN/ALQ-144A IR decoy running equipment .

Chinese army aviation 's new night-vision helmet

Some network exposure of China's future weapons direct 10 test pilot , using head mounted display , making night and under bad weather to improve combat effectiveness . May be developed by Israeli company Lafer Ta Basha (TOPAZ) night targeting pod . The targeting pod small size , light weight, all-weather and can work under adverse weather conditions , reconnaissance and surveillance missions as well as target detection , interception and tracking. Framework for a four- pod stable platform , from the pod components, electronic components and operational control of three parts . The main characteristics of Ta Basha pod ︰ sensor complete with forward-looking infrared , CCD cameras and laser range finder , to meet the helicopter reconnaissance , night flying , all-weather use fire attacks ; the whole system and light weight of the helicopter Weight and center of gravity , and flight speed, climb rate and range of such effects can be reduced to a minimum ; advanced forward looking infrared detector , the second generation of 240 yuan FPP treatment HgCdTe devices on the tanks target detection range for a class Over the same pod ; with perfect tracking equipment , precision tracking of targets can be observed field azimuth 360 degrees , tilt angle of +15 degrees to -110 degrees , 60 degrees per second rotation speed , adopt automatic tracking mode , stability, precision 25 Milliradians , the discovery of the tank target distance of 11.9 km , 4.6 km away from recognition .

These indicators over the Apache 's early model , but it is also the product a few years ago , now there should be a substantial increase in performance . I personally think that , if the distance of the tank to the discovery of 15 kilometers , identification and distance is 8 kilometers, essentially to meet future battlefield needs , and can resist the battlefield anti- helicopter system in the United States " A Cida "( Taiwan, Yao said to buy the system ) and S1 Russian armor system .

Stealth Performance Comparison (anti- radar stealth performance and IR thermal radiation control)

Armed helicopters to reduce the visual probability of discovery is as much as possible make it difficult to find it with the naked eye . To this end , the experts have taken specific measures are: ( 1 ) body structure with thin narrow face layout , to minimize the size of the outline of helicopters ; ( 2 ) to the fuselage and blades coated with non- reflective coating, And the cockpit glass plate used to reduce the reflective scattering area; (3 ) to the body paint and similar surface color camouflage ( camouflage ), to weaken the helicopter itself, the contrast between the background with the environment ; ( 4) The engine exhaust port by internal and external Ducted double-layer design to reduce the flame from the exhaust vent so that the enemy even at night is not easy to see that flame .

Short-lived American RAH-66 Comanche stealth helicopter attaches great importance to the performance

AH-64 helicopter gunships had been used, called the "black hole" of the infrared suppression system, the infrared characteristics of this helicopter has been difficult to existing " infrared homing " air- capture , m -28 are similar Infrared device control features .

It is said that Tiger helicopter early development machine , in order to reduce radar reflection effect . Shape design is likely to cause as much as possible to avoid using electromagnetic Fan She 's angular and flat , as far as possible reduce the rotor 's diameter, by absorbing Xingneng good material to make new复合Wai Ke and external body parts , adversary radars on Zhisheng Ji The detection range can be greatly shortened . However, due to cost reasons, not stealth as the main design. This short-lived United States , " Comanche "is the leader in this area , but the U.S. Defense Department believes that changes in aircraft design changes far from the development of electronic technology , there is rapid development of unmanned aerial vehicles , eventually did not continue to develop this kind of stealth helicopter .

10 on the arms straight , this country has to study, film paper, " anti- radar stealth performance and integration of infrared thermal radiation control compound against the IR / UV Dual Colour Guidance "( both Shen Ping, Liu Jianyong , Hujiang Hua , Wang Jian , PLA University of Corps of Engineers Institute , Jiangsu , Nanjing, 210007 ) . It seems every aspect of our study was not done very late , and very likely in the WZ-10 electronic warfare devices. Moreover, the domestic stealth nano- materials have also made a breakthrough in this regard Takenao 10 will be world-leading .

On present understanding, development of weapons straight 10 attack helicopters have overcome most of difficulties , including the engine, main rotor , protection systems , only detection and fire control system . As soon as possible the successful development of attack helicopters, helicopter Design Institute of China -related , Israel and Italy helicopter optical targeting pod , targeting helmet display system and airborne fire control radar to study . Overall , this is a very appropriate use of the pod medium attack helicopters , after appropriate adjustments , fully integrated into airborne equipment .

But according to the terms of the above information , weapons will be a straight 10 maximum takeoff weight of five tons of medium-sized helicopters , the main task for the anti-tank anti-armor combat , destroy the ground fixed and mobile vital forces, and have considerable combat capability . It 's overall operational performance and technical performance , with Europe's Tiger attack helicopters equivalent since the Airport contains no definite weapon , so operational efficiency with the U.S. AH-1 Cobra helicopters and Italy the A129 quite . And the United States and Russia, AH-64 m 28 attack helicopters and heavy compared to operational capability to attack the weak , if the air war , military maneuvers and empty straight 10 in the edge of weapons , possession mobility, easy maintenance Low prices, purchase and use reasonable cost advantages . Therefore , Wu straight 10 4 A top should not be a big problem.

Possession of a strong light attack helicopter firepower and overall combat capability , better fire control systems, combat and a half Jing big and strong survival advantage . The equipment perspective, the PLA 's 21 army corps, air force and navy three Airborne Division brigade level two divisions , each with at least 12 attack helicopter battalion a total estimated more than 200 Frame to 300 or more , ( I personally think that China should develop multi-purpose helicopters , as -24 m ) would greatly enhance China's military marine firepower .

With the large number of armed helicopters equipped troops , the PLA's combat capability will be greatly enhanced China's military in the field will lead a revolution !
