摘要： Embodiments of a guided munition are provided, as are embodiments of a method for equipping a guided munition with a self-deploying dome cover. In one embodiment, the guided munition includes a munition body, a seeker dome coupled to the munition body, and a self-deploying dome cover disposed over the seeker dome. The self-deploying dome cover is configured to deploy and expose the seeker dome during munition flight in response to aerodynamic forces acting on the self-deploying dome cover.

摘要： A stray light baffle for a seeker or other sensor system and a method for making the same are provided. The seeker, for example, may include a first receiver configured to receive an infrared signal, a second receiver configured to receive a radio frequency signal, a dichroic mirror configured to reflect the infrared signal toward the first receiver and to transmit the radio frequency signal toward the second receiver, and a stray light baffle having a coarse surface comprising a plurality of peaks and a plurality of valleys, wherein an average height of the plurality of peaks is greater than or equal to an average width of the plurality of valleys.

摘要： A cryostat (12) with an actuator (40) which reacts to sensed temperature changes via externally controlled thermal heating generated therein. The actuator (40) is constructed with material having a high coefficient of thermal expansion. A flexible heating element (44) is embedded in the actuator material. A temperature sensor (62) provides a signal to cryostat control electronics. Responding to the temperature signal, the control circuitry (60) regulates current to the heating element (44) in the actuator (40). As the actuator temperature increases due to the heat generated by the heating element (44), it expands and moves open an attached needle (50) relative to an orifice (30), thereby increasing cryogen flow and regulating cooling. When the desired cold temperature is attained, current and heating are stopped. Flowing cryogen cools the actuator which shortens the actuator and pulls the attached needle into the orifice to regulate flow. The heating and cooling cycle repeats itself when the sensed temperature rises to an unacceptable value. The heating element (44) provides the ability to control actuator heating. It provides greater sensitivity and travel by inducing actuator temperature change rates and magnitude significantly larger than cryogen changes in temperature, which limit passive actuator designs.
