Compact high aspect ratio aerodynamic configuration layout structure of fire extinguishing bomb and design method

Abstract

The invention discloses a compact high aspect ratio aerodynamic configuration layout structure of a fire extinguishing bomb. The compact high aspect ratio aerodynamic configuration layout structure comprises a warhead, a bomb body, a bomb tail and four foldable empennages; the warhead is arranged at the front end of the bomb body; the bomb body is a standard cylinder; the bomb tail main body adopts a square body design, the front end of the bomb tail is in smooth transition with the bomb body cylinder, the smoothness of the aerodynamic configuration is guaranteed, the square outer surface is beneficial to fin folding, and the square body further increases the internal volume of the bomb; and the four foldable empennages are folded in the circumferential direction of the bomb tail main body, the envelope size after folding does not exceed the bomb body, the four foldable empennages can adapt to a circular launch canister, it can be guaranteed that wings are more compact in structure when folded and can completely protrude out of the surface of the bomb body when unfolded, the stress area of the wings is increased to a greater extent, and the stability of the bomb is better improved.The aerodynamic configuration layout structure is high in stability, high in filling ratio, compact in structure and particularly suitable for barreled launching.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing bombs, and in particular relates to a compact large-aspect-ratio aerodynamic shape layout structure and a design method of a fire extinguishing bomb. Background technique [0002] The aerodynamic layout is also called the aerodynamic configuration, which refers to the form in which the aerodynamic surfaces, such as the empennage, are mutually arranged along the circumferential and axial directions of the body. font, ring, T or improved ring. The fire extinguishing bomb is a new type of uncontrolled bomb mainly used for forest fire fighting. It has the characteristics of low cost and deep fire extinguishing. It requires good shape stability and a large amount of fire extinguishing agent. Under the condition that the envelope of the bomb's shape and size is limited, there is still a lack of fire extinguishing bombs with high shape, aerodynamic performance stability, and high loading rati...
