Abstract

The invention discloses an aviation piston two-stroke engine supercharging system design method, and belongs to the technical field of aviation piston two-stroke engine supercharging system design. The method comprises the steps that basic parameters and performance strengthening target parameters of the aviation piston two-stroke engine are determined; selecting and matching a supercharger and preliminarily designing structural parameters of a resonant tube; determining common working condition parameters of the aviation piston two-stroke engine and a use weighted value of each working condition; optimizing structure parameters of the resonant tube through a genetic algorithm, and determining control target parameters; and according to a supercharger and the optimized resonance tube, a supercharging system is machined and assembled for the aviation piston two-stroke engine, and test verification is carried out. The design method of the aviation piston two-stroke engine supercharging system is suitable for an aircraft with high lift limit, high maximum level flight speed and long endurance, high comprehensive performance under all working conditions is considered, the design period is short, and the trial-manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of design of an aviation piston two-stroke engine supercharging system, and relates to a design method of an aviation piston two-stroke engine supercharging system. Background technique [0002] In the face of multi-scenario and multi-functional application requirements, the requirements of UAVs for high ceiling, high maximum level flight speed, and long endurance are increasing day by day. With the increase of the altitude and flight height of the take-off site, and affected by the decrease of environmental pressure, the naturally aspirated engine has problems such as reduced intake pressure, significant power attenuation, and poor high-altitude power, which seriously affects the ceiling and maximum level flight speed of the UAV. and flight time performance. The application of the supercharging system can effectively increase the intake pressure of the aviation piston two-stroke engine, restore its high-al...
