Abstract
The turbocharging matching is researched for the problem of power reduction of two-stroke aero engines at high-altitudes. An one-dimensional simulation model of a natural aspirated two-stroke aero engine was established and experimentally verified. Based on the verified model, a turbocharger is matched, and a turbocharged engine model is established. The structure optimizing and control strategies of bypass valve in exhaust system are proposed to broaden the working range of turbocharger through the calculation and analysis of turbocharging matching at variable altitudes. A two-stroke turbocharged aero engine with 76% power recovery at 7 000 m altitude was designed, which can meet the demand of an unmanned aerial vehicle's mission profile.
