Lightweight composite material and metal thrust recovery flapper valve

摘要: The present invention provides a thrust recovery valve (20) that is less expensive and lighter weight while maintaining required system safety. It utilizes doors made partially of plastic material uses aluminum structure on the outer surface door, with main from fiber reinforced material. door injection molded, fiber-reinforced (CP), called "insert" having complex geometric features including aerodynamic inner surface, sculpted hollow surfaces for savings, grooves to hold seals energizing springs. "plate" (21), shaped match airplane skin contour, reinforcing external airplane.
