HAL to equip locally-made helicopter with turbo-shaft engine

Hindustan Aeronautics (HAL) has issued a request for information to supply turbo-shaft engine for 10-12.5 ton AUW class twin engine helicopter.

Besides the engine, HAL also sought technical consultancy on rotor system and review of the transmission system of multi-role helicopter, Sputnik reported Wednesday.

HAL, which is engaged in the design and development of rotary wing aircraft, intends to purchase engine under technology transfer agreement. The preferred total engine weight with all accessories and harnesses is to be within 250 kg.

The engine must be a turbo-shaft type and should be modular in construction.

“Life limited modules should be limited to bare minimum. Engine power should be modulated by a dual-channel full authority digital electronic control (FADEC) system suitable for twin engine application with cross talk facility and digital engine health monitoring and diagnostic system,” the document issued by HAL said.
