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 ...

Biofueled Miniature Turbojet Engine (BIOMITE) [PDF]
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

Turbojet Engine Simulation Using Dymola [PDF]
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & 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

Noise From Turbojet Compressors
The Journal of the Royal Aeronautical Society, 1964SummaryThe noise radiated from the intakes of turbojet engines during landing is already causing a serious nuisance. This paper, which is largely based on the deliberations of an ad hoc working panel of academic experts formed by Rolls-Royce in 1961, describes the characteristics of the noise and discusses possible mechanisms of generation.

Characterization of the Wear in the Turbojet Fins
Key Engineering Materials, 2015The wear is very difficult to characterize because of its complexity and its measurement phenomenon. Our work is to prepare samples Fan blades, worn, to determine the nature of the wear and damage them. For these reasons, the characterization of these samples was conducted in different microscopic and macroscopic scales.
