Abstract

The invention discloses an oil supply atomization device, a combustion chamber device and a micro jet engine, and the oil supply atomization device comprises an oil supply ring connected with an oil supply header pipe; and the evaporation pipe comprises a preheating part and an evaporation part, one end of the preheating part is connected with the oil supply ring, the other end of the preheating part is connected with the evaporation part, and the periphery of the preheating part is wrapped with a heat conduction piece. During working, the oil supply main pipe supplies fuel to the oil supply ring, the fuel enters the evaporation pipe from the oil supply ring and firstly enters the preheating part, and the heat conduction piece can quickly transfer heat in the combustion chamber to the fuel entering the preheating part, so that the fuel enters the evaporation part after being quickly preheated and is sprayed out after further heat transfer by the evaporation part; according to the micro jet engine, fuel can be fully preheated before entering the combustion chamber, so that the fuel is fully evaporated, atomized fuel hot steam which is uniformly distributed is formed, the atomization degree of the fuel is high, combustion is more sufficient and stable, the combustion chamber is not prone to stall, and the micro jet engine is not prone to surging, stopping in the air and the like.

Description

technical field [0001] The invention relates to the technical field of miniature jet engine components, and more specifically, relates to an oil supply atomizing device. In addition, the present invention also relates to a combustion chamber device comprising the above-mentioned fuel supply atomizing device and a microjet engine comprising the combustion chamber device. Background technique [0002] In high-speed small aircraft such as high-speed drones, cruise missiles, jet model aircraft, and target drones, and micro gas turbine power plants, the combustion chamber is a key component, and the performance of the combustion chamber directly affects the performance and reliability of the engine. [0003] In the prior art, in order to simplify the structure and reduce the size and weight of the combustion chamber, the oil supply atomization device of the combustion chamber adopts a hook-type stainless steel evaporator tube, that is, the fuel is atomized by the hook-type stainl...
