Engine Model: Nihka. Other Designations: 17KS12000. Designer: Bristol Aerospace. Developed in: 1980-1982. Application: Upper stages. Gross Mass: 399 kg (879 lb). Empty Mass: 70 kg (154 lb). Propellants: Solid. Thrust(vac): 50.500 kN (11,353 lbf). Isp: 285 sec. Burn time: 17 sec. Country: Canada. Status: Out of production. First Flight: 1981. Last Flight: 1999. The Nihka rocket motor was developed for use as the third stage of the Black Brant X sounding racket. Schedule and cost constraints dictated a low risk development program, which was achieved by using proven hardware wherever possible, together with a high performance propellant/liner system. The motor weighed 398.7 kg and delivered a total impulse of 908,770 N-s in vacuum. The first test flight took place twenty months after initiation of design.
