Dispersion of turbojet engine exhaust in flight

, 1973
The dispersion of the exhaust of turbojet engines into the atmosphere is estimated by using a model developed for the mixing of a round jet with a parallel flow.

An investigation of the precooled turbojet engine.

, 1964
The possibility of extending the range of operation of turbojet engine to hypersonic Mach number and its possible uses have been investigated. It is well known that addition or an afterburner extends the range of turbojet to Mach number of about 3.

THE EFFECTS OF USING NOISE REDUCTION TURBOFAN ENGINE NOZZLE DESIGNS ON A TURBOJET ENGINE

, 2017
Aircraft noise is a complex topic which is projected to increase with the increasing number of aircraft and size of the engines. Turbine-powered aircraft produce sounds that are considered pollutants at certain decibel levels.

Generalized simulation technique for turbojet engine system analysis

, 1972
A nonlinear analog simulation of a turbojet engine was developed. The purpose of the study was to establish simulation techniques applicable to propulsion system dynamics and controls research. A schematic model was derived from a physical description of
