    摘要: A cryogenic cooling system (12) for cooling electromagnetic energy detectors (50). The cooling system (12) includes a first mechanism (18) that accommodates cryogen fluid in one or more spaces (58, 60). A second mechanism (16,42) freezes the cryogen fluid in the one or more spaces (58, 60) adjacent to the electromagnetic energy detectors (50). In a specific embodiment, the electromagnetic energy detectors (50) comprise an infrared focal plane array (50). The second mechanism (16, 42) includes a heat exchanger (16) that is mounted separately from the first mechanism (18). The one or more spaces (58, 60) are fitted with three-dimensional cooling interface surfaces (62, 64). The three-dimensional cooling surfaces (62, 64) are implemented via a thermally conductive matrix (62, 64). The thermally conductive matrix (62, 64) is a copper metal matrix or carbon/graphite matrix, and the solid cryogen reservoir (18) is a beryllium reservoir (18). The solid cryogen reservoir (18) includes integrated mounting features (52, 54) for mounting the reservoir (18) to a missile housing and a surface for attaching the focal plane array (50) to the reservoir (18). The second mechanism (16, 42) includes a Joule-Thomson orifice (42) that employs the Joule-Thomson effect to cool the cryogen fluid to a solid state. The first mechanism (18) includes a selectively detachable cryogen canister that provides pressurized cryogen fluid to the heat exchanger (16). The heat exchanger (16) directs cooled pressurized cryogen fluid to the solid cryogen reservoir (18) and Joule-Thomson orifice (42) and is positioned remotely from the cryogen reservoir (18). In an illustrative embodiment, the heat exchanger (16) outputs cooled cryogen gas to plural solid cryogen reservoirs (18) to cool plural corresponding infrared focal plane arrays (50). A line cutter selectively detaches the gas canister and/or the heat exchanger (16) from the missile in response control signal from a computer. The computer generates the control signal after a predetermined amount of the cryogen fluid is present in the cryogen reservoir (18) or after a predetermined time interval.

    摘要: By sharing tasks between the CV and the KVs, the MKV interceptor provides a cost-effective missile defense system capable of intercepting and killing multiple targets. The placement of the acquisition and discrimination sensor and control sensor on the CV to provide target acquisition and discrimination and mid-course guidance for all the KVs avoids the weight and complexity issues associated with trying to “miniaturize” unitary interceptors. The placement of either a short-band imaging sensor and headlamp or a MWIR sensor on each KV overcomes the latency, resolution and bandwidth problems associated with command guidance systems and allows each KV to precisely select a desirable aimpoint and maintain track on that aimpoint to impact. An implicit divert and attitude control system (DACS) using tow or more divert thrusters performs KV divert and attitude maneuvers to respond to the command guidance pre-handover and to maintain track on the aimpoint to terminal intercept post-handover.
