摘要
为了改善活塞式航空汽油机的高空性能,基于GT-Power软件,建立了活塞式航空汽油机原机和增压机模型,对活塞式航空汽油机进行了原机、一级增压及二级增压模拟研究.研究表明,涡轮增压能有效改善活塞式航空发动机高空性能,一级增压后,该活塞式航空发动机极限工作高度达到海拔7km以上;气动二级增压后,则能达到海拔8～9km,而电控二级增压后,极限工作高度将达到海拔10～11km.
Turbocharging systems for a piston aero-gasoline engine were investigated to improve the engine＇s performances at high altitudes. Simulation models of the piston aero-gasoline engine were developed by GT-Power. The simulation results showed that turbocharging systems can effectively improve the performances of the piston aero-gasoline engine at high altitudes. The engine can work at 7 km altitude when it is one-stage turbocharged. It can work at 8~ 9 km altitude when it is pneumatic controlled two-stage turboeharged. The engine can even work at 10-11 km altitude with electronic controlled two stage turhocharging system.
