The certification philosophy plays an important role in ensuring the airworthiness qualification of a small gas turbine engine designed as a starter unit. The small and compactness of the engine, high rotational speed of the rotors, requirements of torque and starting capability at sea level to high altitude airfields and consecutive starts within stipulated time impose a great challenge from airworthiness point of view. This paper presents the methodology adopted and various stages of qualification, standards followed and results based on which the starter unit has been qualified for fitment on the designated aircraft.

Keywords: starter unit; starting torque; ground start; altitude start; over-speed test; environmental test
