Pressurizing gas distribution mechanism of annular tandem straight-cylinder engine, and annular straight-cylinder engine

Abstract

The invention belongs to the technical field of annular engines, discloses a pressurizing gas distribution mechanism of an annular tandem straight-cylinder engine, and the annular straight-cylinder engine, and aims to solve the problems that an existing annular engine is poor in sealing performance and cannot be used under the conditions of high performance and light weight. The pressurizing gas distribution mechanism of the annular tandem straight-cylinder engine comprises a gas inlet shaft with a gas inlet channel, wherein the gas inlet shaft is coaxially and fixedly connected with a central gas distribution shaft, the periphery of the central gas distribution shaft is sequentially and rotationally connected with a first rotor gas distribution shaft and a second rotor gas distribution shaft in the axial direction of the central gas distribution shaft, and the central gas distribution shaft comprises a connecting flange used for being connected with the gas inlet shaft; and the connecting flange is connected with a barrel body, a plurality of gas inlet ports are formed in the side, facing the connecting flange, of the barrel body in the radial direction of the barrel body, and each gas inlet port communicates with the gas inlet channel.

Description

technical field [0001] The invention belongs to the technical field of piston engines, and in particular relates to a booster gas distribution mechanism of an annular series straight-cylinder engine and the annular straight-cylinder engine, which are used to distribute air to the piston engine. Background technique [0002] The reciprocating piston engine has a simple principle and mature technology, and is widely used in various fields. However, due to the characteristics of the reciprocating motion of the piston and the characteristics of the traditional crank-and-rod mechanism, it is difficult for the traditional reciprocating piston engine to significantly increase the power density and maximum output power. In order to improve the engine Power density and maximum output power, a feasible method is to arrange multiple cylindrical cylinders arranged in parallel along the same circumferential direction in series, and realize the reciprocating motion of the piston relative t...

AI Technical Summary

Problems solved by technology

[0006] 1. The air flow needs to pass through multiple contact surfaces, and there are many contact surfaces that need to be sealed, which not only leads to high manufacturing costs but also easily causes the problem of seal leakage

[0007] 2. A long gas distribution process will cause insufficient exhaust (that is, there is residual exhaust gas in the long gas distribution channel), which will affect the power density and maximum output power of the engine

[0008] 3. Due to the setting of the second air port, the second air channel and the third air port on the main rotor, the structural strength of the main rotor will be reduced, and in order to ensure the structural strength of the main rotor, the size of the main rotor needs to be thickened ( increase in size and weight), which makes it impossible to meet the special requirements for high performance and light weight in some usage scenarios (such as small unmanned platforms), and the thickening of the main rotor will also lead to large inertial force, which further limits the Application Scenarios of Toroidal Tandem Straight Cylinder Engine
