Preliminary design of an ASTOVL strike-fighter

Serghides V.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

1999

nr 9

127-134

The paper presents the Imperial ASF-94A, an advanced short take-off, vertical landing (ASTOVL) strike-fighter design concept. This was originally developed by the author in September 1994, at Imperial College and then became the subject of an eight-month preliminary design study, by a large group of students in the department of Aeronautics. The aircraft was designed primarily for the air superiority role, but with also a good offensive support capability. It is a single-seat, single-engine design, featuring a low-observables configuration with an arrowwing and an all-moving close-coupled foreplane, V-tail, twin diamond intakes and internal weapon bays. Clean configuration aerodynamics and lightweight structural design together with thrust from a powerful, advanced, low bypass ratio, reheated turbofan with a limited single-axis thrust vectoring nozzle and a remote lift-fan, produced a highly effective and manoeuvrable combat with short take-off, vertical landing and high angle-of-attack capabilities. Low ground support, rapid turnaround and enhanced maintainability features where also incorporated in the ASF-94A, from the earliest stages of its design in order to develop a configuration with high overall operational effectiveness. This paper aims to provide a technical description of the ASF-94A and its operational performance and to discuss the design challenges encountered in the development of this innovative concept.

Functional approach to the general scheme synthesis

Malchevky V.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

1999

nr 9

85-90

Two making processes of an aircraft design - stages of structural and parametric synthesis are investigated. It is indicated that structural synthesis and it's milestone - synthesis of an aircraft scheme are principal for reaching effective operation of the vehicle. Instead of the conventional structurally modular approach to a classification of elements of an aircraft the new functional approach is offered which more full to use internal resources of a created technical system and to increase efficiency of an airplane by a combination and adjustment of element's functions. It's shown, that in the basis of new effective aircraft schemes creation is the process of the sanction of technical contradictions; the formal ways of the sanction of these contradictions and, in particular, method of supplying of an 'intellectual supports' to the designer with the help of specialized consulting models are offered.

Evolution of the aircraft design theory, methods and education problems

Liseytsev N.

Research Bulletin / Warsaw University of Technology, Institute of Aeronautics and Applied Mechanics

1999

nr 9

81-84

Modem view on scientific methodological fundamental of the discipline "Aircraft Design" is expounded. Base group of knowledge, experiences and skills in aircraft design education process separated. Learning of them allows graduates reduce period of adaptation in real industrial design process and is good basic for professional growth of young specialist. Actual problems of contents and methods of aeronautical engineering education coordination in aeronautical universities of Europe and America is discussed.
