Afterburners for Turbojet Engines

Journal of the Aeronautical Sciences, 1948
The 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 ...

A Mathematical Model for Windmilling of a Turbojet Engine

Volume 1: Aircraft Engine; Fans and Blowers; Marine; Wind Energy; Scholar Lecture, 2021
Abstract The transient windmilling characteristic of a modern turbojet engine under different flight conditions and altitudes is obtained with numerous tests conducted at an Altitude Test Facility (ATF). A simple and practical mathematical model for predicting the transient and steady-state rotational speed of a simple turbojet engine in

Dynamic modelling of a small scale turbojet engine

2015 European Control Conference (ECC), 2015
Thrust 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 &amp; Exhibit, 2006
This 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

Biofueled Miniature Turbojet Engine (BIOMITE)

50th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2012
The Busemann Advanced Concepts Lab at the University of Colorado Boulder has been researching improvements to small turbojet engines designed for unmanned aerial vehicles for the past three years. The BIOMITE senior design team has continued this tradition by designing adaptations for a commercial-off-the-shelf US Microjet AT-450 turbojet engine to run
