Development of „Marcel” Electronic Control for Turbojet Engines

Abstract

The automatic control of gas turbine engines is essential for the safe operation of aircraft. The control is in most of the cases a FADEC that provides short response times and the number of parameters under the supervision of the system is much higher in comparison with conventional hydromechanic systems. The control can be realized based on different variables, recently, TPR can also be used, which is nowadays utilized as an overriding capability in abnormal situations on large bypass ratio turbofan engines. The goal of this article is to present through measurement data that the TPR is applicable for the normal control of a single stream turbojet engine in the electronic control system as the basic thrust parameter, furthermore introduce the reader into the work done by the author in the past five years in the field of turbojet engine control for radio controlled aircraft.
