Extensions to aircraft pre-design for supersonic aircraft
52nd Aerospace Sciences Meeting, 2014Forecasts predict a strong market for supersonic travel in the business sector. It is especially appealing for high-net-worth individuals because of both, the reduction of travel time and prestige. The ecological and economic challenges that are related to supersonic flight need adequate answers in terms of technology and tools to assess aircraft ...

Supersonic aircraft drag reduction
21st Fluid Dynamics, Plasma Dynamics and Lasers Conference, 1990This paper reviews aerodynamic drag reduction for friction, wave and vortex drag associated with supersonic cruise aircraft and suggests approaches and research directions. Suction laminar flow control may also enable improved low-speed, high-lift systems, improved lift-to-drag ratio for subsonic cruise, reduced parasitic viscous drag for favorable ...

Aircraft Engineering and Aerospace Technology, 1961
Arguments in favour of selecting a cruising speed of about M=2.0 for a long‐range supersonic transport aircraft have been given by Morgan, and Kuchemann has shown that the slender wing shapes provide the basis for the layout of the aircraft, and has given the general properties which would lead to the achievement of optimum cruising lift‐drag ratios ...

The Airworthiness of Supersonic Aircraft
The Aeronautical Journal, 1967SummaryThe safety target for the Supersonic Transport has been set by the governments sponsoring the project. This is to achieve a safety level at least as good as that of subsonic aircraft at the same time. An analysis of present accident trends is used to give more precision to this statement.

IMAGING SUPERSONIC AIRCRAFT SHOCK WAVES
Journal of Flow Visualization and Image Processing, 1997A schlieren imaging system that uses the sun as a light source was developed it) obtain direct flow-field images of shock waves of aircraft in flight. This system was used to study how shock waves evolve to form sonic booms. The image quality obtained was limited by several optical and mechanical factors.

Supersonic and Transonic Aircraft Problems
Journal of the American Rocket Society, 1947A great honor has been conferred on me, especially the invitation^which said that I was particularly qualified" to discuss supersonic and transonic aircraft problems. Throughout my ! disertation the emphasis is going to be placed entirely on that word 'problem'. As so ably put by General Craigie quite recently in that "with respect to many of the major

Advanced supersonic cruise aircraft technology
Acta Astronautica, 1977A multidiscipline approach is taken to the application of the latest technology to supersonic cruise aircraft concept definition, and current problem areas are identified. Particular attention is given to the performance of the AST-100 advanced supersonic cruise vehicle with emphasis on aerodynamic characteristics, noise and chemical emission, and ...

Engineering Systems on Supersonic Aircraft
The Journal of the Royal Aeronautical Society, 1961A great deal has been said and written about the necessity to launch into a completely new standard plateau of systems engineering for supersonic, as distinct from subsonic, aircraft. So far as I have been able to gather, one reason for all this could be the argument that, as the supersonic aircraft will be so costly to operate, i.e.

Range optimization for a supersonic aircraft
Navigation and Control Conference, 1991Range optimal trajectories for an aircraft flying in the vertical plane are obtained from Pontryagin's Minimum Principle. Control variables are load factor n which appears nonlinearly in the equations of motion and throttle setting eta, which appears only linearly.

Thrust Nozzles for Supersonic Transport Aircraft
Journal of Engineering for Power, 1963Supersonic transports will require jet-engine thrust nozzles that are highly efficient from take-off to supersonic cruise in order to minimize the direct operating costs. Variable-area ejectors, plug nozzles, and modifications of these basic types have been tested extensively during the past several years.
