It is designed primarily for [[anti-tank warfare]] missions but has secondary [[air-to-air combat]] capability as well. Initiated by chief designer Wu Ximing, the project had early [[Russia|Russian]] involvement with [[Kamov]] Design Bureau of Russia under a contract with the Chinese government, but the collaboration was abruptly stopped due to fundamental design philosophy disagreements. The Chinese designers and their customer, the [[People's Liberation Army General Armaments Department|PLA General Armaments Department]], preferred a lighter-weight, more agile [[airframe]] with less emphasis on armor. The helicopter was further developed by [[Changhe Aircraft Industries Corporation]] (CAIC) and is locally manufactured.<ref name="kamovfg"/><ref name="kamovaio"/><ref name="kamovavw"/><ref name="kamovbi"/> Nicknames of characters in the Chinese classic novel ''[[Water Margin]]'' have been used to name Z-10 and its light-weight counterpart, the [[Harbin Z-19]]: Z-10 is called '''Fierce Thunderbolt''' (Pi Li Huo, 霹雳火), the nickname of [[Qin Ming]], while Z-19 is called '''Black Whirlwind''' (Hei Xuan Feng, 黑旋风), the nickname of [[Li Kui (Water Margin)|Li Kui]].<ref>{{cite web|url=http://news.qq.com/a/20121115/001407.htm|title=直10直19绰号"霹雳火""黑旋风"取自水浒传|access-date=4 February 2015|archive-url=https://web.archive.org/web/20141113180143/http://news.qq.com/a/20121115/001407.htm|archive-date=13 November 2014|url-status=live|df=dmy-all}}</ref><ref>{{cite web|url=http://www.s1979.com/news/china/201211/1261665612.shtml|title=官方公布武直10及武直19名称：霹雳火与黑旋风|author=Copyright@中国时刻网、深圳广播电影电视集团|access-date=4 February 2015|url-status=dead|archive-url=https://web.archive.org/web/20131016013001/http://www.s1979.com/news/china/201211/1261665612.shtml|archive-date=16 October 2013}}</ref> In September 2016, the PLA announced that all of its [[army aviation]] units had been equipped with the Z-10.<ref>[http://www.airrecognition.com/index.php/archive-world-worldwide-news-air-force-aviation-aerospace-air-military-defence-industry/global-defense-security-news/global-news-2016/september/2908-wz-10-attack-helicopter-now-deployed-in-all-pla-aviation-units.html WZ-10 attack helicopter now deployed in all PLA aviation units] {{Webarchive|url=https://web.archive.org/web/20161220063745/http://www.airrecognition.com/index.php/archive-world-worldwide-news-air-force-aviation-aerospace-air-military-defence-industry/global-defense-security-news/global-news-2016/september/2908-wz-10-attack-helicopter-now-deployed-in-all-pla-aviation-units.html |date=2016-12-20 }} - Airrecognition.com, 8 September 2016</ref> ==Development and history== {{More citations needed|section|date=July 2011}} ===Early exploration=== In 1979, the Chinese military studied the problem of countering large armour formations. It concluded that the best [[Conventional warfare|conventional]] solution was to use [[attack helicopter]]s. Eight [[Aérospatiale Gazelle]] armed with [[Euromissile HOT]] were procured for evaluation. By the mid-1980s, the Chinese decided a dedicated attack [[helicopter]] was required. At the time, they used civilian helicopters converted for the military; these were no longer adequate in the attack role, and suitable only as scouts. Following this, [[China]] evaluated the [[Agusta A129 Mangusta]], and in 1988 secured an agreement with the [[United States]] to purchase [[AH-1 Cobra]]s and a license to produce [[BGM-71 TOW]] missiles; the latter was cancelled following the [[1989 Tiananmen Square protests and massacre]] and the resulting arms embargo. The [[colour revolution]]s prevented the purchase of attack helicopters from [[Eastern Europe]] in 1990 and 1991; [[Bulgaria]] and Russia rejected Chinese offers to purchase the [[Mil Mi-24]]. While attempting to import foreign designs failed, war games determined that attack helicopters had to be commanded by the army, rather than the air force. This led to the formation of the [[People's Liberation Army Ground Force#People's Liberation Army Ground Force Aircraft|People's Liberation Army Ground Force Air Force]] (PLAGFAF), with an initial strength of 9 [[Harbin Z-9]]. The PLAGFAF conducted tactical experiments that would help define the future Z-10's requirements. Research also decided that [[anti-tank missile]]s like the [[BGM-71 TOW]] were inadequate, and favoured an analogue to the [[AGM-114 Hellfire]]. These findings ensured the Z-10 would be based around the new missile. ===Medium helicopter program=== The [[Gulf War]] highlighted the urgent need for attack helicopters, and revalidated the assessment that a purpose-built design was needed. At the time, the Chinese military depended on armed [[utility helicopter]]s such as the [[Changhe Z-11]] and [[Harbin Z-9]]. Also, it demonstrated that the new attack helicopter would need to be able to defend itself against other helicopters and aircraft. The military perceived that once the new attack helicopter entered service, the existing helicopters would be used as scouts. The Attack Helicopter Developmental Work Team (武装直升机开发工作小组) was formed to develop a new medium helicopter design, as opposed to basing the new design on the light helicopters then in service. The [[602nd Special Operations Squadron|602nd]] and 608th Research Institutes started development of the 6-ton class China Medium Helicopter (CHM) program<ref>Hewson, Robert, "China’s Z-10 helicopter built on Western expertise", Jane’s Defence Weekly, 13 April 2005</ref> in 1994. A secret contract was signed with the [[Kamov]] Design Bureau of [[Russia]] to design and verify the helicopter airframe and propulsion.<ref name="kamovfg" /><ref name="kamovaio" /><ref name="kamovavw"/><ref name="kamovbi"/> The program was promoted as a civilian project, and was able to secure significant Western technical assistance, such as from [[Eurocopter]] (rotor installation design consultancy), [[Pratt & Whitney]] Canada (PT6C turboshaft engine), and [[Agusta Westland]] (transmission).<ref>{{cite web|url=http://mil.qianlong.com/4919/2006/07/28/2420@3335046.htm|title=Jane's Helicopter Markets & Systems|url-status=dead|archive-url=https://web.archive.org/web/20061228140337/http://mil.qianlong.com/4919/2006/07/28/2420%403335046.htm|archive-date=2006-12-28}}</ref> The Chinese concentrated on areas where it could not obtain foreign help. ===Attack helicopter program=== [[Pratt & Whitney]], alongside [[Hamilton Sundstrand]] divisions of the [[United Technologies Corporation]], unlawfully transported and provided US military technology into this program. In an effort to maintain profits, they conspired to cover up these facts. They were found guilty of these charges in June 2012. Several of the charges were deferred adjudications.<ref>{{cite web |url = https://www.justice.gov/opa/pr/united-technologies-subsidiary-pleads-guilty-criminal-charges-helping-china-develop-new |title = United Technologies, Pratt & Whitney Canada and Hamilton Sundstrand Corporations Also Agree to Pay More Than $75 Million to U.S. Government |publisher = [[United States Department of Justice]] |date = 28 June 2012}}</ref> In 1998, the 602nd Research Institute proposed to either separate the armed helicopter program from the medium helicopter program, or devote all resources to the armed helicopter program. The 602nd Research Institute called its proposed armed helicopter design the Z-10 ({{Zh|c=直-10|s=|t=|p=|l=helicopter-10|labels=}}). As a result, most of the resources went to the Z-10, although the medium helicopter program continued with reduced priority; the medium helicopter could continue to develop technology used by both military and civilian aircraft. The Z-10 program was called the Special Armed Project (专武工程), a short form for Special Use Armed Helicopter Project (专用武装直升机工程). Development was kept under stricter secrecy than the [[Chengdu J-10]] fighter. Nearly [[Renminbi|¥]] 4 billion was initially invested and the Z-10 became one of the most important programs begun in the [[Five-Year Plans of China#The Ninth Five-Year Plan, 1996-2000|9th 5-yr plan]]. Publicly, the 602nd Research Institute was assigned as the chief designer to promote the illusion of it being a domestically developed attack helicopter, while [[Harbin Aircraft Manufacturing Corporation]] (HAMC) of [[China Aviation Industry Corporation II]] (AVIC II) was assigned as the primary manufacturer. Nearly four dozen other establishments participated in the program. In the summer of 1999, [[China Aviation Industry Corporation II|AVIC II]] began to use a [[CAMC Z-8]] to test newly developed Z-10 sub-systems. In autumn of the same year, a [[Harbin Z-9]] was added to the test aircraft inventory. These tests concentrated on sub-systems such as the fire-control systems, [[HOTAS|HOTAS controls]], and navigation systems. South [[Africa]] provided limited help in the area of flight stability, based on experience from designing the [[Denel Rooivalk]]. South African assistance ceased in 2001. ===New manufacturer=== In 2000, the Chinese again attempted to obtain a Russian attack helicopter, but the deal for the [[Kamov Ka-50]] fell apart just as the [[Mil Mi-28]] deal several years earlier. The repeated failures in obtaining foreign attack helicopters reinforced feelings that China had no choice but to ignore foreign options and develop its own such aircraft, and work on the Z-10 accelerated. In the same year, [[Harbin Aircraft Manufacturing Corporation|HAMC]] transferred most of its production responsibilities to [[Changhe Aircraft Industries Corporation|CAIC]] of [[China Aviation Industry Corporation II|AVIC II]]. The official reason given was excessive workload; HAMC was busy producing the [[Eurocopter EC120#Variants|HC120]] and [[Harbin Z-9]], as well as other fixed-wing aircraft such as the [[Harbin Y-12]], and thus was stretched to the limit. However, many speculated that HAMC was not performing well enough due to rigid and ineffective Soviet-style management practices, believed to have caused the company to go into debt. Although HAMC was in the process of reform, which finally succeeded, the government and military were weary and impatient. The SH-5 factory had become very profitable after its successful restructuring and reform, but it had to get out of the aircraft manufacturing business for good, manufacturing pressurized tanks and other specialized containers. It was decided that the Z-10 program was too important to be run by HAMC, so a more stable contractor was sought and [[Changhe Aircraft Industries Corporation|CAIC]] was selected. HAMC still retained responsibility for production of certain sub-systems and components, for which it could utilize experience gained from manufacturing parts for foreign helicopters and fixed-wing aircraft such as the [[Embraer ERJ 145 family]]. In May 2002, the Z-10 tail rotor and some other components were tested on the ground by the 602nd Research Institute. In April 2003, a Z-10 prototype completed its maiden flight at Lumeng (吕蒙) airfield, the airfield having been assigned to [[Changhe Aircraft Industries Corporation|CAIC]] for such use. According to Chinese sources, the initial test flights were concluded on December 17, 2003, whereas according to other sources they were completed nine months earlier, in March 2003. According to [[Jane's Information Group]], a total of 3 prototypes had completed over 400 hours of test flights by this time. By 2004, 3 more prototypes were built, for a total of 6, and a second stage of test flights were concluded on December 15, 2004. In one of the test flights, the future commander-in-chief of the [[People's Liberation Army Ground Force]] Air Force (PLAGAF), Song Xiangsheng (宋湘生), was on board the prototype. A third stage of intensive test flights followed, taking place during both day and night. By January 2006, weaponry and sensor tests, including firing of live ammunition, were taking place. Prototypes and a small number of pre-production aircraft are in service with the Chinese military for evaluation. The design is undergoing continuous minor modifications and upgrades based on the feedback. ===Amphibious role=== In March 2014, the PLA released pictures of a Z-10 helicopter conducting deck trials with a [[People's Liberation Army Navy]] [[Type 072A-class landing ship]]. The purpose may be to qualify the helicopter on ships to provide air support for landing parties launched from the ship. Type 072A-class ships have a helipad but no hangar or support facilities for the aircraft on board. The Z-10 may also be qualified on the larger [[Type 071 amphibious transport dock]].<ref>[http://navyrecognition.com/index.php?option=com_content&task=view&id=1663 Chinese Army Z-10 Attack Helicopter conducts trials at sea with Navy Type 072A Landing Ship] {{Webarchive|url=https://web.archive.org/web/20140323194519/http://navyrecognition.com/index.php?option=com_content&task=view&id=1663 |date=2014-03-23 }} - Navyrecognition.com, 23 March 2014</ref> ==Design== {{More citations needed|section|date=July 2011}} [[File:Changhe WZ-10.jpg|thumb|Changhe Z-10]] The [[Kamov]] design bureau was contracted to perform the development work under a secret contract. Kamov worked with the Chinese to establish base specifications, such as weight, speed, and payload capacity, after which they had full freedom to design the helicopter. Kamov designed, tested, and verified an early stage of helicopter design, after which it was provided to the Chinese team and was substantially modified. Although the earliest stage of the design was made in Russia, the prototype construction, flight testing, and further development was performed by the Chinese.<ref name="kamovfg" /><ref name="kamovaio" /><ref name="kamovavw"/><ref name="kamovbi"/> === Flight instrumentation === There are two configurations of the flight instrumentation for Z-10, one developed from a similar foreign system (rumored to be French), and the other one indigenously-developed, and both configurations share the same holographic [[head-up display|heads-up display]]. The difference in layout between the two configurations is that in one configuration, there are three color [[liquid crystal display|LCD]] [[multi-function display]]s (MFD), while in the other, these are replaced by two larger LCD MFDs. It's not clear which one originated from the foreign system and which is indigenously developed, but it's reported that the practice of having different configurations, thanks to the modular design, is for export purposes, to fit the potential customer countries’ pilots’ habits. However, in early 2018, it was revealed that the 2-piece MFD version was the one selected to enter service.<ref name=wzzsj10ybp>{{cite web |url=https://item.btime.com/m_991adededa64affe8 |title=见过武直-10座舱内部吗？曝光一下超乎你的想象啊！ |access-date=February 3, 2018 |archive-url=https://web.archive.org/web/20190115182306/https://item.btime.com/m_991adededa64affe8 |archive-date=January 15, 2019 |url-status=dead |df=mdy-all }}</ref> ===Mission-related avionics=== [[File:WZ-10 at Military Museum of the Chinese People's Revolution.jpg|thumb|Z-10 at the Military Museum of the Chinese People's Revolution]] ====Electro-optics==== One of the two primary fire control systems (FCS) is the [[electro-optics|electro-optical]] (optronics) system, which utilizes experience gained from earlier manufacturing of similar French and Israeli systems, combining the best of the two, but only hardware wise. The software is completely indigenously developed by China. The optronics FCS is manufactured by the 218th Factory of [[Norinco|China North Industries Group Corp]], later reformed as China North Industries Group Corporation Electro-Opticals Science & Technology Ltd.

The HMS is standard for the Z-10. The HMS is based on the earlier HMS used on the [[Harbin Z-9|Z-9W]], which was first shown at the 5th [[Zhuhai Airshow]] held in 2004. At the 7th Zhuhai Airshow held in 2008, the developer confirmed that the HMS is fully integrated into the FCS and the onboard navigational systems.<ref name=wzzsj10tkmzj/> Navigational information can be displayed on the MFD, pilots can also fly the Z-10 in a 'hands-on' manner, including at night using HMS-compatible [[Night vision device|night vision goggles (NVG)]] similar to the French TopOwl HMS used on the [[Eurocopter Tiger]].

The previous claim of WZ-9 being a Chinese version of the MTR390 proved to be false, because according to the publicized official Chinese governmental technical documents, VK-2500, TV3-117, and PT6 are all classified as third generation turboshaft engines, a category WZ-9 belongs to, while the MTR390 is classified as a fourth generation turboshaft engine.{{Citation needed|date=March 2014}}{{clarify|date=March 2014}} The WZ-9 is the second least powerful engine out of the five tested for the Z-10, but enjoys the advantage of having no foreign-built components.{{Citation needed|date=March 2014}} Furthermore, since it is 100% built in China, there are no political issues that would affect the purchase of vital parts. The WZ-9 is in full production to power the Z-10. Specifications for the WZ-9 turboshaft engine that is installed in Z-10 for mass production : *'''Power:''' 930 - 957&nbsp;kW *'''Fuel consumption:''' 0.311&nbsp;kg/(kW·h) *'''Pressure ratio:''' > 8 *'''Inlet temperature:''' 1355 degrees Celsius *'''Power-to-weight ratio:''' 5.4 The WZ-9 has been updated with a new variant, the WZ-9G, with a higher thrust of 1200&nbsp;kW. Another new engine, developed by China and Turbomeca, is the WZ-16.<ref>{{Cite web|url=https://www.safran-helicopter-engines.com/engine-partnerships/partnerships/wz16/wz16|title=Safran Helicopter Engines}}</ref> Its maximum output power is 1500&nbsp;kW, and it will be installed in the Z-10 and Z-15/EC175. After the installation of the new engines, power would increase by 500&nbsp;kW for the Z-10. With WZ-9 turboshafts, the Z-10 can carry 16 HJ-10 missiles with maximum takeoff weight, but the payload is very heavy for the Z-10 and engines and is potentially risky for flying, so 8 missiles with other weapons serve as the maximum useful payload. After the new WZ16 engines are installed in the Z-10, it can carry 16 of them like the AH-64. ===Weaponry=== Due to its modular design concept, the Z-10 can be armed with a wide variety of weaponry. The adaptation of the Chinese GJV289A standard, the Chinese equivalent of the MIL-STD-1553B databus architecture, enables weaponry of both Soviet and western origin to be adopted by the Z-10. Offensive weaponry consists of machine guns, cannons, rockets, and missiles. The stub wings have two [[hardpoint]]s each for a total of four, each [[hardpoint]] being able to carry up to 4 missiles, for a total of up to 16. ====Cannon and machine guns==== Internal armament consists of a gun mount installed on the chin of the aircraft. Two stub wings provide attachment points for external ordnance or gun pods.<ref>{{Cite web|url=http://www.sinodefence.com/airforce/helicopter/wz10.asp|archiveurl=https://web.archive.org/web/20060424031842/http://www.sinodefence.com/airforce/helicopter/wz10.asp|url-status=dead|title=Sinodefence.com|archivedate=April 24, 2006|website=www.sinodefence.com}}</ref> The guns are mounted either in the chain gun form, or in the turret.

When using larger air-to-air missiles such as the [[PL-9]] or similar missiles such as [[AIM-9 Sidewinder]], the total number is reduced to 2.
