| Two stage turbocharging system for a piston engine was improved to meet higher performance requirements of propulsion system for unmanned aircraft. Based on aeroengine operation process calculation theory fitrst stage turbocharger model was built using CF1) software and its accuracy was also validated. The parameters of the two stage turbocharger and the pressure ratio matching of high pressure and law pressure compressor were determined. The arrangement concepts of two stage turbocharger and intercooler were discussed. The high altitude characteristics of the two stage turbocharger were analyzed.The acceptable, turbocharger were selected for the two stage turbocharging system |
