TAPAS UAV to Receive Indigenous CRDi Diesel Engine Developed by VRDE-JAYEM Automotives
India's TAPAS UAV is set to achieve a major milestone with the integration of an indigenously developed diesel engine, marking a crucial step towards self-reliance in UAV propulsion technology. In a significant move, two units of a newly developed 2.2L, 4-cylinder inline turbocharged CRDi engine have been installed in select TAPAS prototypes, replacing imported powerplants.
Developed by the Vehicle Research and Development Establishment (VRDE) in collaboration with JAYEM Automotives Ltd, this engine boasts a maximum power output of 180 HP at an altitude of 11,000 feet and is designed to operate effectively up to 32,000 feet. The incorporation of a Full Authority Digital Engine Control (FADEC) system enables fully automatic engine management, eliminating the need for pilot intervention while ensuring optimized performance. Furthermore, its dual-redundancy system enhances operational reliability, a critical factor in unmanned aerial applications.
Ground testing of these engines has been successfully completed following extensive standalone evaluations. The program now moves into the flight-testing phase, with trials expected to conclude by mid-2025. If successful, these indigenous engines will officially replace the foreign-manufactured power units currently used in TAPAS UAVs, strengthening India’s strategic autonomy in defense technology.
This upgrade is part of India's broader efforts to refine the TAPAS UAV, which has faced hurdles in meeting operational endurance and altitude requirements outlined by the Indian Armed Forces. By equipping the platform with a domestically developed engine, the program aims to improve both performance and logistical efficiency.
