Abstract
A rocket motor includes a case and first and second nozzles in the case. The first nozzle is disposed in the second nozzle. The first nozzle includes a forward leg, a rear leg, and an intermediate leg. The intermediate leg has a convex conical geometry, and the forward leg has a forward lip that is spaced from the case. The rear leg has a rear lip that is spaced from the case. The forward leg and the rear leg at least partially define a flow passage through the first nozzle. The first nozzle is exclusively secured by the intermediate leg to at least one of the case or the second nozzle. At least a portion of a fragmentation system is disposed between the first and second nozzles.
Claims12
A rocket motor comprising:
- a case;
- a nozzle system including first and second nozzles disposed in the case, the first nozzle at least partially disposed in the second nozzle, the first nozzle including:
- a forward leg, a rear leg, and an intermediate leg between the forward leg and the rear leg, wherein the intermediate leg has a convex conical geometry,
- wherein the forward leg has a forward lip that is spaced from the case such that there is a forward gap between the forward lip and the case,
- wherein the rear leg has a rear lip that is spaced from the case such that there is a rear gap between the rear lip and the case,
- the forward leg and the rear leg at least partially defining a flow passage through the first nozzle;
- and
- wherein the first nozzle is exclusively secured by the intermediate leg to at least one of the case or the second nozzle,
- a fragmentation system, at least a portion of which is disposed between the first and second nozzles.
A nozzle system comprising:
- a nozzle circumscribing an axis, the nozzle being formed of a brittle material and having a convergent leg, a divergent leg, and an intermediate leg between the convergent leg and the divergent leg, the convergent leg and the divergent leg at least partially defining a flow passage through the nozzle.
