- The LUH is the latest helicopter to be designed and developed by the Rotary Wing Research and Design Centre (RWR&DC) of HAL after Advanced Light Helicopter (ALH) and Light Combat Helicopter (LCH).
- HAL is conducting test flights on three prototypes of the Light Utility Helicopter (LUH).
- The maiden flight of the first prototype, named LUH PT-1, was conducted in September 2016. Based on the experience gained from the development of the PT-1, the second prototype LUH PT-2 was integrated with a modified tail boom. The PT-2 made its first flight in May 2017.
- HAL concluded maiden test on the third prototype in December 2018.
- High-altitude and cold weather trails on the helicopter are scheduled in early 2019.
Design and Technology of the HAL Light Utility Helicopter (LUH):
- The multi-role helicopter is designed to meet both military and civilian needs.
- The LUH will be capable of performing multiple missions such as surveillance, reconnaissance, rescue, medical evacuations, and cargo/troop transport.
- The helicopter’s cabin and airframe are made of composite material that features two access doors and windows on port, as well as starboard sides of the hull for the entry and exit of passengers.
- The next-generation helicopter is also fitted with high-capacity skid-type landing gear.

Engine of the HAL Light Utility Helicopter (LUH):
- The LUH is powered by an Ardiden 1U (Shakthi) engine designed by Safran.
- The two-stage turbine engine develops a maximum power of 1,058 kWenabling the rotorcraft to perform search-and-rescue missions, long-range flights, and hover operations.
- The maximum continuous power output of the engine is 912 kW.
- The Ardiden 1U engine integrates a two-stage centrifugal compressor along with a single-stage gas generator turbine equipped with single crystal blades.
- It also features a reverse flow combustion chamber, an integral oil system, and a dual-channel Full Authority Digital Engine Control (FADEC) system.
- The engine can be operated in Auxiliary Power Unit (APU) mode, which enables power supply for all the lighting, electronics and communications systems aboard the helicopter.
Propulsion and Performance of the HAL Light Utility Helicopter (LUH):
- The 3 t-class helicopter is capable of performing in high-altitude areas such as the Himalayas.
- The LUH has a service ceiling of 6,500 m and can perform manoeuvres with ease due to the sufficient power generated by the engine.
- It is capable of carrying payloads weighing up to 500 kg.
- The Light Utility Helicopter can attain a maximum speed of 235 km/h (127 kt) during a level flight at the sea level.
- It can endure up to a range of 350 km, which can be extended to 500 km with the integration of internal fuel tanks.
