UH-60 / S-70A Black Hawk Multi-Mission Helicopter

UH-60 / S-70A Black Hawk Multi-Mission Helicopter

The UH-60 Black Hawk, developed by Sikorsky, has been operational in the US Army since 1978.

Variants of the Black Hawk are operational or have been ordered by 25 international customers: the Argentine Air Force, Royal Australian Army, Bahrain, Brazil, Brunei, Chile, Colombian Air Force, Egypt, Greece, Hong Kong, Israel, Japan Self Defence Force, Jordan, Korea, Malaysia, Mexico, Morocco, People’s Republic of China, Royal Saudi Land Forces Army Aviation Command, the Turkish Jandarma, Spain, The Philippine Air Force, Taiwan, and Thailand.

The S-70A helicopter is the export version of the multi-mission UH-60 Black Hawk helicopter.

UH-60 Black Hawk helicopter

More than 2,000 UH-60 Black Hawk helicopter variants are in service with the US Military and more than 600 exported.

Black Hawk helicopters have logged over four million flying hours, including a diverse range of combat missions in Grenada, Panama, in the liberation of Kuwait, Somalia, Afghanistan, Iraq and numerous humanitarian and rescue missions including operations in Bosnia.

The helicopters are manufactured at the Sikorsky Aircraft Corporation production facilities based in Stratford, Connecticut, USA. Licensed production of Black Hawk helicopters is also carried out in Japan and the Republic of Korea.

The primary mission of the Black Hawk helicopter is as a troop carrier and logistical support aircraft, but in addition, the helicopter can be configured to carry out medical evacuation, command-and-control, search-and-rescue, armed escort, electronic warfare and executive transport missions.

UH-60 Black Hawk helicopter design

Black Hawk has low detectability and outstanding nap-of-the-earth flight capabilities. The aircraft is tolerant to small arms fire and most high-explosive, medium-calibre (23mm) projectiles. The flight controls are ballistically hardened and the helicopter is equipped with redundant electric and hydraulic systems.

“The S-70A Black Hawk cabin provides accommodation for 11 fully equipped troops or four litters.”

The helicopter has the ability to absorb high-impact velocities. The fuel system is crash-resistant and self-sealing. The crew seats and the landing gear are energy absorbing.

UH-60M Black Hawk helicopter upgrade programme

In April 2001, the US Army approved an upgrade programme for more than 1,500 Black Hawks to UH-60M standard. The first flight of the UH60M took place in September 2003 and three helicopters have been delivered for the test programme.

“The UH-60M features new wide chord composite spar main rotor blades.”

The US Army initially decided to opt for new build helicopters rather than upgrade existing airframes.

The new-build helicopter entered low-rate initial production (LRIP) in April 2005. The first of 22 new UH-60Ms was delivered in July 2006. Initial operational evaluation (OPEVAL) was successful and a decision on full-rate production of 1,227 helicopters was authorised in December 2007 with the award of a five-year contract. Under this contract six UH-60M utility and 20 HH-60M combat rescue helicopters were ordered in March 2008.

In December 2007, the US Army ordered 11 low-rate initial production (LRIP) upgrade UH60M. The UH-60M upgrade completed its maiden flight in August 2008. More than 950 aircraft are scheduled to be delivered by 2025. As of July 2012, Sikorsky had delivered 400 UH-60M helicopters.

The UH-60M features new wide chord composite spar main rotor blades (which provide 500lb more lift than the current UH-60L blade), strengthened fuselage and advanced infrared suppression.

The fly-by-wire glass cockpit has a digitised 1553 bus-based avionics suite with four Rockwell Collins multi-function displays, four-axis fully-coupled autopilot, two Canadian Marconi (CMC) electronic flight management systems, dual Honeywell embedded GPS inertial (EGI) navigation system, digital moving map and Goodrich integrated vehicle health management system (IHVMS).

The new General Electric T700-GE-701D engine (with full authority digital electronic control) is more powerful and provides additional lift during sling load operations.

S-70A Black Hawk helicopter

The S-70A Black Hawk helicopter is flown by a crew of three: the pilot and the copilot at the flight deck and one crew member in the cabin. The S-70A helicopter is equipped with a glass cockpit and digital avionics.

In addition, S-70 customers may select a digital automated flight computer system (AFCS) to simplify pilot workload. An electronic flight information system (EFIS) provides primary pilotage and navigation displays for the aircrew.

S-70A weapons

The S-70 is qualified as a launch platform for the laser-guided Hellfire anti-armour missile. The Black Hawk can carry 16 Hellfire missiles using the external stores support system (ESSS). The ESSS has the capability of carrying a 10,000lb payload of missiles, rockets, cannons and electronic countermeasures pods. The helicopter can also accommodate additional missiles, supplies or personnel inside the cabin.

The S-70 can mount 7.62mm or .50-calibre machine guns in the windows.

US Army Black Hawks are fitted with the Goodrich AN/AVR-2B laser threat warning system.

Cargo

The cabin provides accommodation for 11 fully equipped troops or four litters (stretcher patients) with a medical officer for medical evacuation missions.

“The S-70A helicopter is tolerant to small arms fire.”

The cabin is equipped with a ventilation and heating system. The S-70A can carry external loads up to 9,000lb (4,072kg) on the cargo hook, for example, a 155mm howitzer. The main cabin can be cleared of troop seats for transportation of cargo. Additional stores can be carried on the external stores support system.

Communications

The S-70A is equipped with a voice and data communications suite including VHF, UHF communications, an identification friend or foe (IFF) transponder, secure voice communications, satellite communications and an intercom system.

Engines

The S-70A is equipped with two General Electric turboshaft engines, type T700-GE-701C. US Army Blackhawks are being fitted with the latest version, the 701D, which is rated at 2,000shp.

The internal fuel tanks have a capacity of 1,360l. Auxiliary fuel can be carried with 1,400l in two internal fuel tanks and 1,740l externally.

Variants

The UH-60 comes in many variants, and many different modifications. The U.S. Army variants can be fitted with the stub wings to carry additional fuel tanks or weapons. Variants may have different capabilities and equipment to fulfill different roles.

U.S. Army personnel were on board, but the flying was done by the helicopter. During a two-hour flight, the Black Hawk featured terrain sensing, trajectory generation, threat avoidance, and autonomous flight control. It was fitted with a 3D-LZ laser detection and ranging (LADAR) system. The autonomous flight was performed between 200 and 400 feet. Upon landing, the onboard technology was able to pinpoint a safe landing zone, hover, and safely bring itself down.
  • OPBH: On 11 March 2014, Sikorsky successfully conducted the first flight demonstration of their Optionally Piloted Black Hawk (OPBH), a milestone part of the company’s Manned/Unmanned Resupply Aerial Lifter (MURAL) program to provide autonomous cargo delivery for the U.S. Army. The helicopter used the company’s Matrix technology (software to improve features of autonomous, optionally-piloted VTOL aircraft) to perform autonomous hover and flight operations under the control of an operator using a man-portable Ground Control Station (GCS). The MURAL program is a cooperative effort between Sikorsky, the US Army Aviation Development Directorate (ADD), and the US Army Utility Helicopters Project Office (UH PO). The purpose of creating an optionally-manned Black Hawk is to make the aircraft autonomously carry out resupply missions and expeditionary operations while increasing sorties and maintaining crew rest requirements and leaving pilots to focus more on sensitive operations.
