Solid engine

Abstract

The invention discloses a solid engine. The solid engine comprises a shell, ignition boxes, a solid fuel and an igniter; the shell is composed of an upper layer shell, a middle layer shell and a lowerlayer shell; the upper layer shell, the middle layer shell and the lower layer shell are sequentially connected from top to bottom by connecting rings; the shell is of a reversed conical structure; the shell is provided with a buffering pad; priming charges are arranged among the upper layer shell, the middle layer shell and the lower layer shell; the upper layer shell, the middle layer shell andthe lower layer shell are each internally provided with a combustion chamber inside which the solid fuel is placed; the tail part of each combustion chamber is provided with a Laval jet tube; each ignition box is installed between the corresponding combustion chamber and the corresponding Laval jet tube; each ignition box is connected with the igniter through a central pipe; the igniter is composed of a nozzle, ignition powder and an artillery primer; and the ignition powder is arranged between the nozzle and the artillery primer. By adopting a form that the bodies of the reversed conical shell are connected in series, the solid engine disclosed by the invention greatly increases the utilization rate of the fuel, and the design of the connecting rings improves the boosting efficiency of the engine.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to a solid engine. Background technique [0002] At present, a solid engine is a power device that converts chemical energy into mechanical energy through the combustion of solid fuel. A conventional solid engine is composed of a fixed casing. Unfavorable use of thrust greatly reduces the working efficiency of the engine. Not only that, some solid engines use a single ignition method, which often causes misfires. Moreover, the power of conventional engines is small, and it is very easy to cause The impact causes damage to the body. Contents of the invention [0003] The object of the present invention is to provide a solid motor to solve the problems raised in the above-mentioned background technology. The solid fuel is consumed first, which greatly improves the utilization rate of fuel. The design of the connecting ring enables the upper and lower parts to be separated...
