Abstract
In order to gradually realize the conversion of aircraft from traditional energy to clean energy,it is an important research direction to transform traditional turboprop aircraft into distributed electric propulsion propeller aircraft.In this paper,the cruising performance of the Y12F aircraft is constrained,and the wing parameters of the Y12F aircraft modified into a distributed propeller aircraft are modified according to the momentum theory.The number of distributed electric propulsion propellers was comprehensively evaluated and determined from three aspects:propeller disc area,propeller and motor matching relationship,and propeller quality.The propeller is designed according to the tensile requirements of the cruising and climbing task profiles;The final distributed propeller-wing model and the prototype model were compared and analyzed in OpenVSP.The results show that the slipstream effect of the distributed propeller is more obvious at small speed and high angle of attack,which can be used to improve the performance indicators of aircraft in the take-off and climbing phases.In the cruising and climbing state,the upward lift characteristics of the distributed propeller are better than the downward lift,and the lift coefficient can be increased by about 5%,but at small speeds,the increase in the lift coefficient is at the cost of an increase in drag coefficient.The research in this paper provides a reference for the overall design of the transformation of traditional turboprop aircraft to distributed propeller aircraft.关键词
