The engine is the compact Olympus HP E-startturbine engine, comprising a single-stage radial compressor, an annularcombustion chamber and a low-mass, high-performance axial flow turbine. Theengine has been integrated into a sturdy metal frame that holds it firmly,while enabling accurate measurement of the thrust produced by the engine. Theengine inlet has been replaced with a custom fabricated frontal duct, to enablethe air mass flow rate to be accurately measured. An electronic preprogrammedcontroller constantly supervises the engine, ensuring safe operating conditionsat all times. The engine is controlled via the software, which provides userswith a friendly graphical interface for real-time monitoring and operation.This software controls the engine speed, which is electronically controlledusing a high-precision fuel gear pump. This method gives a very fast engineresponse.
