India’s state-owned Hindustan Aeronautics Limited (HAL) is set to commence work for the Establishment of the TPE331-12B Engine Facility for HTT-40 in the Engine Division, HAL (BC). This comes after HAL signed a contract worth over US$100 million for the supply and manufacture of 88 TPE331-12B engines/kits along with maintenance and support services to power the Hindustan Trainer Aircraft (HTT-40) last year.

The HTT-40 prototypes are powered by TPE331-12B engines and have been serving well since 2014. Last year Entering into this “Manufacturing & Repair license agreement for Honeywell TPE331-12B Turboprop engine” marks a major milestone in the execution of a 70 HAL HTT-40 aircraft contract with the Indian Air Force (IAF).

The TPE331-12B engine is a single-shaft turboprop engine with an integral inlet and gearbox, a two-stage centrifugal compressor, a power turbine, a gearbox, a three-stage axial turbine, and a turbine exhaust diffuser as well as EEC for reliable power and outstanding operational characteristics.

The establishment of the TPE331-12B Engine Facility is a significant development for India’s aerospace industry. It will allow HAL to manufacture and support the TPE331-12B engine in India, which will reduce the country’s reliance on foreign suppliers. The facility will also create jobs and boost the local economy.
