Abstract

The invention discloses a deflection warhead. The deflection warhead comprises a swinging cone, a spherical surface pair shell, a warhead shell and a driving mechanism, wherein the warhead shell is a circular platform and is provided with a cavity penetrating through the bottom surface and the top surface of the warhead shell; the swinging cone comprises a cone, a rotary sphere body and a square shaft; a plane is turned on the outer surface of the rotary sphere body; the rotary sphere body is fixed at the center of the bottom surface of the cone through the plane; a spherical surface opposite to the plane is matched with the spherical surface pair shell to form a spherical surface pair; the other end of the spherical surface pair shell is connected with one end, with the small bottom area, of the warhead shell; one end of the square shaft is fixed on the rotary sphere body and the other end of the square shaft is located in the warhead shell; the driving mechanism is located in the warhead shell. According to the deflection warhead, the aim that the swinging cone swings in a relatively large range can be realized and the deflection warhead has the advantages of high control precision and rapid response.

Description

technical field [0001] The invention belongs to the field of deformable aircraft, and in particular relates to a deflected warhead. Background technique [0002] As early as 1946, the engineering community proposed the concept of a "movable nose cone", which was the prototype of a deflecting warhead. Regarding the research on deflected warheads, NASA has conducted a series of theoretical analysis and experimental research. Among them, Lander proved through wind tunnel tests that the aerodynamic characteristics of the deflected warhead are superior to those of the duck-type projectile. Domestic researchers such as Wang Ju also proved through experiments that the aerodynamic characteristics of the deflected warhead are superior to those of the canard rudder. In addition, the wings and empennage can also control the flight, but the disadvantages of the wings and the empennage are that the area of ​​the wings is larger, the required control force is larger, and the correction e...
