Dynamic modelling of a small scale turbojet engine
2015 European Control Conference (ECC), 2015Thrust vector can effectively improve the fighter's maneuverability and flight safety, increasing the survival rates in the air combat. As the key component of thrust vectors, the turbojet engine's dynamics and characteristics have a great influence on the performance and control of thrust vectors.

Turbojet Engine Simulation Using Dymola
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006This work describes the development of a global model of a modified turbojet engine for dynamic behavior simulation. The Modelica language is used for the simulation of this model. A Modelica package was created for the basic components suitable for such models. The model is based on a general turbojet engine and a turbofan engine. The engine component

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 ...

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 ...
