Abstract: A method of applying thermal and acoustical insulation by spraying an air entrained stream of high velocity pils onto an overhead surface in concert with a liquid-based adhesive is disclosed.

Abstract: Systems and methods for providing back-up hydraulic power for aircraft are disclosed. A system in accordance with one aspect of the invention includes a hydraulic supply line, a hydraulic return line, and a hydraulic actuator coupled between the supply line and the return line. The system can further include a fluid energy storage device coupled in parallel with the hydraulic actuator between the supply line and the return line, and a first valve (e.g., check valve) coupled in series between the supply line and the fluid energy storage device. A second control valve can control the flow of fluid from the fluid energy storage device to the actuator. In particular embodiments, the fluid energy storage can be coupled to an actuator that deploys and retracts an aerial refueling device.

Abstract: Chemical vapor deposition apparatus and method are provided with coating gas distribution and exhaust systems that provide more uniform coating gas temperature and coating gas flow distribution among a plurality of distinct coating zones disposed along the length of a coating chamber.
