WZ-10 Attack Helicopter
The primary mission for the treetop hugging WZ-10 is battlefield interdiction, eliminating the enemy ground fixed and mobile forces, and concurrently certain air combat ability. The WZ-10 (Wuzhuang Zhisheng-10) is generally similar to the South African Rooviak and Italian Agusta A129. The PLA Army Aviation long lacked an attack helicopter such as the AH-64 Apache or Mi-28 Havoc. The limited attack helicopter force consisted of 30-40 Z-9Ws and 8 SA-342L Gazelles, along with 60 Mi-17 Hips with unguided rocket launchers. Prior to the WZ-10 China had yet to produce an indigenously designed helicopter. The WZ-10 is thus a bellwether of the improvements in China's helicopter design and production capabilities. Although the helicopter might still not be as capable as the U.S. AH-64 Apache, it will probably play a significant role in Army Aviation modernisation and force compabilities.
Development of a dedicated attack helicopter began in the mid-1990s at the 602 Institute and Changhe Aircraft Industry Company (CHAIC) in Jingdezhen, Jiangxi Province. According to another report, the PLA orignally selected the the MI-35 but chose the Rranco-German Tiger as the source of emulation. Around 1991-92 the PLA leased a single Pakistani AH-1 for technical evaluation. The WZ-10 attack helicopter suffered several delays due to engine related troubles, and finally flew for the first time on 29 April 2003.
The helicopter's net weight is approximately 5,500 kilograms. The helicopter approximate length is 14 meters, is 3.8 meters high, and is roughly 4.3 meters at its widest point. The main rotar consists of 4 blades made up of a compound material. The diameter of the blades is approximately 12 meters length.
Initially the WZ-10 prototypes were powered by Canadian PT6C-76C engines but the production version are likely to use the WZ-9 engines. At one time the WZ-10 was believed to have two European MTR 390 turboshafts, though this now appears in error. Initially there was speculation that the design used the power plant and transmission derived from the Harbin Z-9, with the fuselage modified to accommodate two pilots. However, over time it became clear that the WZ-10 was the military componment of the Chinese Medium Helicopter [CMH], and thus shared a common power train with the Z-15 [AC352].
Two wings along the fuselage that are roughly 4.32 meters long may carry 1,500 kilograms of munitions, including a 57.0 mm multibarrel rockets, the red arrow anti-tank missile. A 23 mm machine gun is fixed to the cabin at the front of the helicopter. The helicopter can carry up to 8 ATGMs, or IR-guided short-range AAMs.
The navigation and avionics are probably from domestic sources. The WZ-10 is equipped with FLIR thus allowing an operations in all weather. The navigation system consists of radioaltimeter, doppler radar and GPS. The fire control system is similar to the French Starry Night digital integration design. Reports indicate that the WZ-10 has an optics system that relays sensor information to the pilots helmets; essentially a system similar to the US Integrated Helmet and Display Sighting System (IHADSS). The helmet system also controls the direction that the machine gun is aiming. This allows the pilots to have an improved situation awareness as they can monitor flight systems and observe the terrain.
The WZ-10 has a non-traditional [for China] design that uses composite and radar absorbant materials. The WZ-10 is equipped with radar warning systems and with systems that will alert the crew that it has been targetted with laser range finders. The helicopter is also equipped with passive countermeasures and in an effort to reduce fratricide is equipped with IFF. The WZ-10 has modified engine exhausts to reduce IR signature of the helicopter. The cabin's bulletproof glass may resist 7.62 millimeter ammunition and composite armor under the cabin resists 12.7 millimeters machine gun fires. The cabin is equipped to maximize fire protection and thw WZ-10 is also outfitted with ejection seats similar to the Ka-50.
Future upgrades to the WZ-10A will likely include new a radar, fire control systems, infrared exhaust suppression and the ability to be flown from naval vessels. Future upgrades to the WZ-10 may include sensor package carried on the Z-11 light helicopter that will improve target acquisition.
By 2012 the Z-10 helicopter was in production and initial batches were delivered to the People�s Liberation Army of China in 2009 and 2010. The primary mission of the Z-10 is anti-armor and battlefield interdiction. Weapons of the Z-10 have included 30-mm cannons, anti-tank guided missiles, air-to-air missiles and unguided rockets.
On June 28, 2012 Pratt & Whitney Canada Corp. (PWC), a Canadian subsidiary of the Connecticut-based defense contractor United Technologies Corporation (UTC), pled guilty to violating the Arms Export Control Act and making false statements in connection with its illegal export to China of U.S.-origin military software used in the development of China�s first modern military attack helicopter, the Z-10. In addition, UTC, its U.S.-based subsidiary Hamilton Sundstrand Corporation (HSC), and PWC all agreed to pay more than $75 million as part of a global settlement with the US Justice Department and State Department in connection with the China arms export violations and for making false and belated disclosures to the U.S. government about these illegal exports.
Since 1989, the United States has imposed a prohibition upon the export to China of all U.S. defense articles and associated technical data as a result of the conduct in June 1989 at Tiananmen Square by the military of the People�s Republic of China. In February 1990, the U.S. Congress imposed a prohibition upon licenses or approvals for the export of defense articles to the People�s Republic of China. In codifying the embargo, Congress specifically named helicopters for inclusion in the ban.
Dating back to the 1980s, China sought to develop a military attack helicopter. Beginning in the 1990s, after Congress had imposed the prohibition on exports to China, China sought to develop its attack helicopter under the guise of a civilian medium helicopter program in order to secure Western assistance. The Z-10, developed with assistance from Western suppliers, is China�s first modern military attack helicopter. During the development phases of China�s Z-10 program, each Z-10 helicopter was powered by engines supplied by PWC. PWC delivered 10 of these development engines to China in 2001 and 2002. Despite the military nature of the Z-10 helicopter, PWC determined on its own that these development engines for the Z-10 did not constitute �defense articles� requiring a U.S. export license, because they were identical to those engines PWC was already supplying China for a commercial helicopter.
Because the Electronic Engine Control software, made by HSC in the United States to test and operate the PWC engines, was modified for a military helicopter application, it was a defense article and required a U.S. export license. Still, PWC knowingly and willfully caused this software to be exported to China for the Z-10 without any U.S. export license. In 2002 and 2003, PWC caused six versions of the military software to be illegally exported from HSC in the United States to PWC in Canada and then to China, where it was used in the PWC engines for the Z-10.
PWC knew from the start of the Z-10 project in 2000 that the Chinese were developing an attack helicopter and that supplying it with U.S.-origin components would be illegal. When the Chinese claimed that a civil version of the helicopter would be developed in parallel, PWC marketing personnel expressed skepticism internally about the �sudden appearance� of the civil program, the timing of which they questioned as �real or imagined.� PWC nevertheless saw an opening for PWC �to insist on exclusivity in [the] civil version of this helicopter� and stated that the Chinese would �no longer make reference to the military program.� PWC failed to notify UTC or HSC about the attack helicopter until years later and purposely turned a blind eye to the helicopter�s military application.
HSC in the United States had believed it was providing its software to PWC for a civilian helicopter in China, based on claims from PWC. By early 2004, HSC learned there might be an export problem and stopped working on the Z-10 project. UTC also began to ask PWC about the exports to China for the Z-10. Regardless, PWC on its own modified the software and continued to export it to China through June 2005. PWC anticipated that its work on the Z-10 military attack helicopter in China would open the door to a far more lucrative civilian helicopter market in China, which according to PWC estimates, was potentially worth as much as $2 billion to PWC.
These companies failed to disclose to the U.S. government the illegal exports to China for several years and only did so after an investor group queried UTC in early 2006 about whether PWC�s role in China�s Z-10 attack helicopter might violate U.S. laws. The companies then made an initial disclosure to the State Department in July 2006, with follow-up submissions in August and September 2006. The 2006 disclosures contained numerous false statements. Among other things, the companies falsely asserted that they were unaware until 2003 or 2004 that the Z-10 program involved a military helicopter. In fact, by the time of the disclosures, all three companies were aware that PWC officials knew at the project�s inception in 2000 that the Z-10 program involved an attack helicopter.
PWC exported controlled U.S. technology to China, knowing it would be used in the development of a military attack helicopter in violation of the U.S. arms embargo with China. PWC took what it described internally as a �calculated risk,� because it wanted to become the exclusive supplier for a civil helicopter market in China with projected revenues of up to two billion dollars. Several years after the violations were known, UTC, HSC, and PWC disclosed the violations to the government and made false statements in doing so.
