Researchon Aerodynamic Layout of Propulsion System for Hybrid Electric Commuter Airplane
摘要
Abstract
The VSPAERO aerodynamic analysis module is used to calculate the aerodynamic characteristics of propeller slipstream taking X-57 wing as an example.The aerodynamic analysis results are compared with the CFD analysis data in the literature to verify the accuracy and reliability of the software.With the application of the software to 19 commuter aircrafts,and the parametric modeling of three aerodynamic layouts of 1 to 3 pairs of motors+proepellers is carried out respectively.The position parameters,size parameters and performance parameters of propellers are adjusted,and the lift and drag characteristics of aircrafts flying at different angles of attack at cruise Mach number are analyzed.The results show that the six-propeller aerodynamic layout is the best of the three schemes,which can significantly reduce the induced resistance of the whole aircraft,with 14.8％increase of the total lift drag compared with two propellers and 31.9％increase compared with four propellers.关键词
