Multi-mode pulse detonation engine

Abstract

The invention provides a multi-mode pulse detonation engine. The cycle operation period of the multi-mode pulse detonation engine comprises seven processes of air admission, oil injection, compression, ignition, detonation, work, injection and air exhaust. The multi-mode pulse detonation engine is mainly composed of an output shaft, a cylinder, a rotor, rotating plates, connecting rods, connecting rod fixing disks and guide rails and the like. The output shaft, the rotor and the connecting rod fixing disks are assembled together through splines, and the output shaft and the rotating plates are assembled together through spindle sleeves. One end of each of the two connecting rods is connected with one rotating plate, and the other end of each connecting rod is connected with one connecting rod fixing disk. The output shaft equipped with the rotor and the rotating plates is arranged in the cylinder, blades on the rotor divide the interior of the cylinder into a plurality of sectorial spaces, each sectorial space is provided with one rotating plate, the blades on the rotor, the rotating plates and the inner wall of the cylinder form an enclosed detonation chamber, and the detonation chamber is sectorial. The cylinder wall is provided with an air inlet, an oil injection port, an ignition port, an injection port and an air exhaust opening. When the engine rotates, the connecting rods control the rotation of the rotating plates, and the motion of the connecting rods is controlled by the guide rails.

Description

technical field [0001] The present invention relates to a new type of conventional fuel engine. Background technique [0002] Since human beings have used the thermal power of conventional fuels, steam engines, two-stroke engines, four-stroke engines, rotary engines, turbojet engines, turbofan engines, and rocket engines have been invented. The pulse detonation engine is still in the research stage and has not yet been successfully developed. . The goals of this kind of technological development and progress of mankind are: environmental protection, small size, high power, simple structure, easy production, fuel saving, and wide application. But from the engine that the mankind have invented and applied, all there are many shortcomings, as: 1, steam engine is an external combustion engine, and volume is big, thermal efficiency is low, and pollution is big. 2. Two-stroke and four-stroke engines have crankcases with heavy and complex structures; they belong to isobaric combu...

AI Technical Summary

Problems solved by technology

However, from the point of view of the engines that have been invented and applied by humans, there are many shortcomings, such as: 1. The steam engine is an external combustion engine, which has large volume, low thermal efficiency, and large pollution

2. Two-stroke and four-stroke engines have crankcases with heavy and complex structures; they belong to isobaric combustion and have low thermal efficiency

3. Rotary engine, poor sealing performance, low thermal efficiency, poor environmental protection

4. Turbojet, turbofan, and rocket engines require high material requirements; low thermal efficiency, poor economy, and poor environmental protection

4. The above-mentioned engines that have been practically used are all single-mode engines, which only have a single-mode engine function and cannot be used universally, so the application is limited

5. Conventional pulse detonation engines are currently being researched all over the world and have not yet been invented. Judging from the published research materials, it can only be a dual-mode engine, that is, rocket engine mode and air-breathing pulse detonation engine. , so its application is also limited, it can only be used in the aerospace field, and it is not suitable for the application of vehicles and ships

For example, China invested tens of billions to establish a large aircraft project. The engine cannot be produced by itself. It has to be bought from Europe and the United States. Europe and the United States find various excuses to delay delivery, which hinders the development of China's large aircraft, and its future fate is still unknown; another example is China's advanced fighter jets. , large transport aircraft, and large ships have been repeatedly delayed due to lack of advanced engines

China has also invested a lot of manpower and material resources in research, but it is all imitation and follow-up, with little effect
