    摘要： An aircraft engine variable area fan nozzle structure disposed abaft a thrust reverser, including a sleeve translatable over a cascade array, comprises two semi cylindrical segments that can be axially translated and radially tilted to enlarge the fan duct exhaust area in order to optimize exhaust pressure and associated noise in high thrust circumstances such as on take-off, and to constrict that area under lower thrust conditions such as cruise. The segments are moved by actuators anchored to the fixed engine framework and independently of the thrust reverser translating sleeve. Each actuator incorporates a linear variable differential transformer acting as a fan nozzle position sensor. The tilting movement is imposed by the pivoting links of each segment to carriages that ride in a non-linear trackway secured to a thrust reverser translating sleeve slider. In an alternate embodiment of the invention, the thrust reverser sleeve actuator and the variable area fan nozzle actuator are coaxially mounted in a compact assembly anchored to stationary components of the nacelle.

    摘要： A semi-flexible laminar silicone foam rubber-base heater for high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses superimposed adhesively bonded layers of an etched foil heater element containing layer, a high-to-low heat thermal transition layer, a thermal fuse laden silicone foam rubber insulation layer and a durable wrapping layer. The system can provide for the combined use of highly controllable etched foil heater elements, clean silicone foam rubber insulation, and inexpensive mechanical thermal fuses safely in a high heat gas supply and exhaust line environment.
