Harbin Z-20

The Harbin Z-20 (Chinese: 直-20) is a Chinese medium-lift utility helicopter produced by the Harbin Aircraft Industry Group (HAIG). It was first flown on 23 December 2013 and has a maximum takeoff weight in the range of 10 tonnes (22,000 lb).[2][3] The Z-20 can operate from locations above 4,000 m (13,000 ft) in altitude as well as from the Liaoning aircraft carrier.[4][5] It is regarded to be comparable in performance to the US-made Sikorsky UH-60 Black Hawk helicopter, of which the civilian Sikorsky S-70C-2 variant has been used by the People's Liberation Army since 1984.[6]

Development

edit

The People's Liberation Army Air Force (PLAAF) has had a requirement for a high-altitude medium utility helicopter that can operate in the mountainous regions in China since the 1980s. In 1984, the PLAAF acquired 24 Sikorsky S-70C-2s with enhanced General Electric T700-701A engines from the US government.[4]

China was unable to purchase more Sikorsky aircraft following the fallout from the 1989 Tiananmen Square protests that resulted in an EU and US arms embargo. This led to the development of an indigenous so-called "10-tonne helicopter project" that started in 2006, and the Z-20 made its first flight on 23 December 2013.[4]

Helicopter production in China received a massive boost after the 2008 Sichuan earthquakes highlighted the value of helicopters in humanitarian missions.[7] In addition to the PLAAF, the Z-20 will likely be used by other services in the People's Liberation Army.[8] It could fill the role of a multi-role naval helicopter for the People's Liberation Army Navy (PLAN) that is small enough to be interoperable across all PLAN vessels while still have a full suite of anti-submarine warfare (ASW) capabilities installed.[4][9]

The Z-20 has been tested carrying missiles on wing pylons.[10]

A stealth Z-20 variant has been indicated under development since 2015.[11] One analyst said China could produce the stealth variant relatively easily because of their access to a modified MH-60 Black Hawk tail section, recovered by Pakistani security forces after a crash during the Bin Laden raid.[12] In May 2021, the concept model of the stealthy Z-20 variant was public revealed. The model displayed a trapezoidal airframe, a shrouded main rotor hub, and an upper-facing ventilation system located on an enlarged tail boom.[13]

Design

Z-20 Helicopter

The Z-20 is based on the 1970s S-70/UH-60 Black Hawk,[3] which China acquired in the 1980s.[4] Pakistan may also have allowed China to examine wreckage from the US special forces Black Hawk abandoned during the assassination of Osama bin Laden on 1 May 2011.[14][15]

The helicopter uses fly-by-wire controls and a five-bladed main rotor; the Black Hawk has four blades. The tail-to-fuselage joint frame is more angular than the Black Hawk's, for greater lift, cabin capacity, and endurance. The fairings behind the engine exhausts and on the spine are likely for satellite communications or the BeiDou satellite navigation system.[16] The Z-20 carries multiple defensive countermeasures, including radar warning receivers (RWR) and missile approach warning system (MAWS), and four chaff and flare launchers mounted for 360-degree coverage.[17]

The Z-20 is believed to be powered by the domestic WZ-10 turboshaft engine providing 1,600 kW (2,100 shp) of power,[18][19] significantly improved from the engines on the S-70-C2[17] and is slightly more powerful than the latest iteration of the Black Hawk engine, the GE T700-701D.[20] The Z-20 also incorporates new technologies that reduce weight and improve lift as well as cutting edge de-icing tech on the rotor-blades. These features enable it to conduct operations at altitudes above 4,000 m (13,200 ft).[4] The engine has an emergency thrust of 2,000 kW (2,700 shp).[21] Compared to the S-70-C2, the Z-20 has overall improvements to the speed, service ceiling, range, and payload.[17]

Variants

PLAAF airborne corps air assault variant, featuring additional hardpoints for weapons and EO sensors.[26]
Z-20KS
PLAAF airborne corps search and rescue variant.[27]
Z-20J
Naval utility/transport variant.[28]
Z-20F
Naval ASW variant.[9][29] Equipped with surface radar under nose, pylon for torpedoes, dipping sonar underbelly and bubble window for observation.
Z-20 PAP
variant for People's Armed Police (PAP).[30]
Z-21
A dedicated attack helicopter based on the Z-20 airframe. The Z-21 has a tail section and rotor configuration similar to the Z-20 but with a thinner fuselage. A tandem cockpit replaces the side-by-side seating on the original, and a 23 mm (0.91 in) autocannon is mounted below. A cheek fairing is added for additional ammunition and avionics. A mmW radar is mounted on top of the rotor mast. The engine is rated at 1,790 kW (2,400 shp) with exhaust direction is changed to upward-facing, reducing the infrared signature. Six hard points on the stub wings to provide more firepower than the Changhe Z-10.[31][17][32] The helicopter was first observed in China in March 2024.[33]
