Nihka


Bristol Aerospace solid rocket engine. 50.5 kN. Upper stages. Out of production. Isp=284s. Used on Black Brant 10 launch vehicle. First flight 1981.

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.

Application: Upper stages.

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
