---

AKA: 17KS12000;Bristol 440. Status: Active. Date: 1980-1982. Thrust: 50.50 kN (11,353 lbf). Gross mass: 399 kg (879 lb). Unfuelled mass: 70 kg (154 lb). Specific impulse: 285 s. Burn time: 17 s.

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.

Propellant Formulation: HTPB.
