ACTIVE LAUNCH AIRCRAFT WITH RAMJET ENGINE FORMED ON THE BASIS OF FLIGHT TRANSFORMATION
241 KB
This paper presents a variant increasing range of the aircraft with active principle of the launch under tight dimensions and weight constraints. It is based on the use of rocket-ramjet engine, which is formed during the flight by transformation the airframe. The research tools that allows you to simulate the movement of the aircraft on the trajectory and the functioning of the ramjet engine in variable external conditions for the analysis of different variants of the proposed decision are developed. In this paper we define the design parameters and algorithms of the active start aircraft with ramjet engine rational from the point of maximum range. Sketch study carried out for one of the variants with the recommended design parameters and operation algorithms that maximize range, to confirm the technical feasibility of the idea to form the ramjet engine during the flight. For this variant it is consider the trajectory with program-controlled path, which together with the ramjet engine allowed to reach the final value range 98 km. This is 60% higher than the best of the existing analogue made with the same dimensions and weight constraints.
