Combustion jet engine

Abstract

The invention discloses a combustion jet engine, comprising an inner shell, wherein the inner shell is provided with a combustion chamber and a combustion chamber spout; the combustion chamber is provided inside with a spark plug, a fuel nozzle and a compressed gas nozzle; the invention also comprises an outer shell, wherein the outer shell is provided with a diversion cavity which is penetrated fore and aft, the inner shell is fixed in the diversion cavity. Based on the expansion process that high temperature and high pressure gases generated after the combustion of the fuel and the compressed or non-compressed gases are ejected from the combustion chamber and the work done by the ejected high speed kinetic energy gases on outside air or water, the combustion jet engine can directly receive the powerful reaction force from outside air or water, thereby leaving out the intermediate transmission link and fully utilizing the energy generated by the combustion of the fuel and the gases. The overall structure of the invention has the advantages of simple structure, practicability and convenient operation and control, and can widely applicable to all equipments on the land, above the water, on the water surface or under the water.

Description

technical field [0001] The present invention relates to an engine, in particular to a combustion jet engine which can be used on water, in the air, in water, underwater or on land. Background technique [0002] As a product of the industrial revolution, the engine has been widely used in all aspects of our work and life. Generally, the engines we use can be divided into internal combustion engines and external combustion engines from the working position of the fuel chamber, and can be divided into gasoline engines, diesel engines and mixed gas fuel engines from the type of fuel burned. In the structure of these engines, it must include Cylinders, pistons, cams, crankshafts, oil injection / air ports, various lubricating oils, sealing rings and other parts can drive the cams and crankshafts through the reciprocating motion of the pistons in close cooperation with each other, thereby driving the machine to be safe, reliable and normal. operation. If they are installed on a sh...

Problems solved by technology

If they are installed on a ship, they also need to be equipped with corresponding gearboxes, drive shafts and propellers and other bulky and heavy parts, especially the gearboxes, drive shafts and propellers used on large ships. Its weight can sometimes reach hundreds of tons. In order to make it run at a high speed from a standstill, the engine consumes a lot of fuel and generates a lot of heat and noise. This complex structure and bulky engine and propeller , it is not easy to disassemble and maintain during the maintenance process. Overhaul and replacement need to enter a professional dock for operation, which not only increases the manufacturing cost of the ship, takes up a lot of space in the hull, and the later maintenance and maintenance process is complicated. , which seriously limits the further expansion and use of ships, how to solve the problems encountered in the use of the existing engines with complex structures, high machining accuracy requirements, and cumbersome maintenance processes, and provide a more suitable for the development needs of modern society , a novel engine with a wider application field is the problem to be solved by the present invention
