The Development of the Whittle Turbojet
Journal of Engineering for Gas Turbines and Power, 1998Sir Frank Whittle passed away on August 8, 1996, at the age of 89, in Maryland. His work in developing the turbojet can truly be said to represent one of the greatest mechanical engineering achievements in the last 70 years. The development of the turbojet demanded that Whittle face almost insurmountable technical and institutional challenges.

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 ...

Supersonic Turbojet Noise Reduction
International Journal of Aeroacoustics, 2013Observations and Large Eddy Simulations are presented of a supersonic jet from a nozzle representative of high-performance military aircraft such as the Saab Gripen. The nozzle has a design Mach number of 1.56 and is examined at its design condition with a surrounding secondary flow at Mach numbers of 0.0, 0.1 and 0.3. The nozzle is investigated in its

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.
