SAE Technical Paper Series, 1962
<div class="htmlview paragraph">Aircraft hydraulic systems have progressed from simple to complex, reliable systems, and in the future, with the Mach 3 aircraft, will be called upon to perform even more tasks. A review of past accomplishments, with a presentation of areas where progress is needed is examined in this paper.</div>

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.

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.

The Digital Age: Turbojets and Computers
2023Abstract Chapter 6 offers a parallel analysis of the mid-twentieth century. It shows how a century later, history seemed to repeat itself. Turbojets, container ships, computer technologies, and satellite communications transformed the world in much the same way as railroads, steamships, the automatic printing press, and the telegraph had
