Turbojet and Turboprop Engine Controls

THE gas turbine fuel control situation is in a state of confusion, the author feels, because of such factors as the newness of gas turbine development, the lack of comparative evaluation tests on controls, and the lack of time for the results of field experience to become generally known among administrative personnel.

After analyzing the present status and discussing the functional requirements of jet controls, Mr. Mock considers the following questions:

1. 1.
   Is the fuel control part of the control of the engine or of the airplane?
2. 2.
   What are some of the special difficulties of the jet control engineer in meeting military needs?
3. 3.
   Who should supervise the selection and adaptation of a fuel control for a given jet engine and airplane?
