Abstract
In accordance with at least one aspect of this disclosure, an actuation system for a guided munition, includes a reservoir disposed in a guided munition body housing a compressible fluid in a compressed state, a fluid path connecting the reservoir in fluid communication with a heat exchange volume, a throttling orifice disposed in the fluid path configured to expand the compressible fluid, and an actuation path connecting the heat exchange volume in fluid communication with a moveable component. The actuation path can be configured to supply pneumatic pressure to the moveable components.

An actuation system for a guided munition, comprising:
- a reservoir disposed in a guided munition body housing a compressible fluid in a compressed state;
- a fluid path connecting the reservoir in fluid communication with a heat exchange volume;
- a throttling orifice disposed in the fluid path configured to expand the compressible fluid;
- and
- an actuation path connecting the heat exchange volume in fluid communication with a moveable component, wherein the actuation path is configured to supply pneumatic pressure to the moveable component, wherein the moveable component includes a nose cone segment mounted to the guided munition body.
A guided munition comprising:
- a guided munition body;
- a moveable component mounted for movement relative to the guided munition body;
- and
- an actuation system configured to move the moveable component, the actuation system comprising:
- a reservoir disposed in the guided munition body housing a compressible fluid in a compressed state;
- a fluid path connecting the reservoir in fluid communication with a heat exchange volume;
- a throttling orifice disposed in the fluid path configured to expand the compressible fluid;
- and
- an actuation path connecting the heat exchange volume in fluid communication with the moveable component, wherein the actuation path is configured to supply pneumatic pressure to the moveable component, wherein the moveable component includes a nose cone segment mounted to the guided munition housing.
