Radial work rotor engine

Abstract

The invention discloses a rotary engine. A compressed air buffer chamber (2), a combustion chamber (3) and a rotor chamber (4) are formed in a shell (1) of the engine; an air outlet of an air compressor (13) is communicated with the compressed air buffer chamber (2) which is communicated with the combustion chamber (3) through a one-way valve (5); the combustion chamber (3) is connected with a fuel injection device (6) and a correct time ignition device (7); an air injection port of the combustion chamber (3) is communicated with the rotor chamber (4); a rotor (9) is arranged in the rotor chamber (4), and consists of a rotor shaft (10) and rotor blades (11); the rotor blades (11) are concentrically distributed on the rotor shaft (10) circularly; and the rotor shaft (10) is arranged on theshell of the engine and is provided with the air compressor (13). The rotary engine has simple structure, less parts, easy manufacture, stable performance, and simple maintenance, and can use variousfuels.

Description

technical field [0001] The invention belongs to the field of engines, and in particular relates to a radial power rotor engine. Background technique [0002] At present, the engines of ground vehicles are mainly piston engines. Piston engines: first, they are stable at medium and low speeds, but their power decreases at high speeds, and their fuel efficiency is low; second, the reciprocating motion of pistons and connecting rods causes vibration, torque The alternating change of three is large; the three structures are complex and difficult to manufacture. [0003] The turboshaft engine has large effective power and low vibration, and is widely used in the field of small and medium-sized aircraft. However, due to the continuous combustion working mode of the turboshaft engine, the combustion chamber cannot form an effective closed space, and the explosive power of the fuel is small, so a large amount of fuel is required. The continuous combustion of compressed air and fuel ...

[0002] At present, the engines of ground vehicles are mainly piston engines. Piston engines: first, they are stable at medium and low speeds, but their power decreases at high speeds, and their fuel efficiency is low; second, the reciprocating motion of pistons and connecting rods causes vibration, torque The alternating changes are large; the three structures are complex and difficult to manufacture

[0003] The turboshaft engine has large effective power and low vibration, and is widely used in the field of small and medium-sized aircraft. However, due to the continuous combustion working mode of the turboshaft engine, the combustion chamber cannot form an effective closed space, and the explosive power of the fuel is small, so a large amount of fuel is required. The continuous combustion of compressed air and fuel produces a large amount of high-temperature gas that acts on the entire turbine blade at the same time. The turbine speed is high, and the power is high. At the same time, the fuel consumption rate and speed are higher than that of the piston engine, and the low-speed performance is poor; The structure of the turbine blade makes it difficult to manufacture the turbine blade, resulting in a large amount of gas leakage and poor sealing effect, which wastes part of the power
