Controller Design for Micro Turbojet Engine
2020 12th International Conference on Electrical Engineering (ICEENG), 2020Modern turbojet engines are controlled using digital controllers. First of all, the micro turbojet engine discrete model is identified. System identification technique utilized real data obtained from jet cat P200sx engine running experiments. Digital PID controllers are mostly used for controlling these engines.

Development study of a precooled turbojet engine
Acta Astronautica, 2010Abstract A precooled turbojet engine has been developed by JAXA used for the hypersonic airplane and spaceplane. The subscale engine named “S-engine” whose thrust and weight are about 1.2 kN and 100 kg was designed, fabricated and tested. The components and the system firing tests under the sea-level-static condition were successfully conducted.In ...

Reduction of Turbojet Engine Noise
2004The urgency of the problem of jet noise reduction has been rising again at the present stage of aircraft technology development. The main reasons are the following. The studies of attenuation of turbo-machine noise have demonstrated that the jet is one of the main noise sources even in engines with high by-pass ratios.

Variable Structure Control of a Turbojet Engine
1986 American Control Conference, 1986We study the fuel control problem of a single-spool turbojet engine. A transfer function approximation method is utilized to identify linear models about operating points. Then, a sliding mode control is developed to regulate the fuel flow so that the engine speed and temperature are within their physical constraints, based on the identified linear ...
