Hypersonic aircraft with ramjet engine with enhanced flight performance

摘要

1. A hypersonic aircraft (GLA) with a ramjet engine, in which, in the front surface, all points of which have x-coordinates less than the x-coordinate of the ramjet engine’s combustion chamber entrance, there are Q openings, gas-dynamically connected to the tank with combustible gas, where the x axis is directed from the nose to the tail of the GLA, characterized in that the front surface of the GLA has such a shape that there is at least one plane такая such that the points γ on the surface of the GLA are normal to the surface and GLA are perpendicular to P, have projections onto P forming at least one closed loop G on P, and the distances from these points γ to P do not exceed 0.1L, where L = xx is the longitudinal dimension of the circuit G, x = x is the largest value the x-coordinates of the point on the circuit Г, x = x- the smallest value of the x-coordinate of the point on the circuit Г; the free volume V is at least 20% of the corresponding volume of the GLA V, where the free volume V is bounded by the plane П, surface S and a cylindrical surface with a cylindrical guide surface G and forming a cylindrical of the normal surface to P, S is the part of the surface of the GLA, the points of which have projections onto P lying on the circuit G or inside it, the volume V is limited on one side by the surface of the GLA, on the other hand, by a cylindrical surface with a guide on a cylindrical surface G and with a generatrix a cylindrical surface parallel to the x axis, on the third side, with a plane normal to the x axis and passing through the point x = x, where x = x is the largest x-coordinate of the point on the contour Г; the holes Q are located on S so that x-x 0.2 L, xx 0.2L, where x = x is the smallest value of x-ko the ordinates of the point on the contour Г, x = x- the largest value
