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

Afterburners for Turbojet Engines
Journal of the Aeronautical Sciences, 1948The general problem of pure jet aircraft take-off distance is indicated, and the basic reasons for the excess-thrust deficiency as compared to propeller aircraft are shown. The inherent advantages and disadvantages of several methods of short-duration thrust augmentation, such as fluid injection or rocket boosters, to alleviate the difficulties are ...
