A sub-idle speed control apparatus for reducing the thrust of an airplane turbine engine is provided. The subject invention reduces the compressor discharge pressure measured by an existing pressure sensing means which proportionally reduces the fuel flow to the engine. Hence, the engine speed is reduced resulting in a lower engine thrust. A switch activates the apparatus which closes a normally open valve in the existing pressure line between the compressor and the pressure sensing means and diverts the pressure through a by-pass line having a restricto...
1. A sub-idle speed control apparatus for reducing the thrust of a turbine engine of an airplane, said engine including a compressor, a pressure sensing means in communication with said compressor through a fluid pressure line for sensing the compressor discharge pressure, and a fuel control system in communication with said pressure sensing means for supplying fuel to the engine in proportion to the compressor discharge pressure, said sub-idle speed control apparatus comprising: a normally open valve means intermediate said fluid pressure line; a by...
