摘要
结合升力风扇系统动量理论方程和固定翼飞机的升阻计算模型,建立了升力风扇垂直起降飞机升阻特性估算模型。通过该模型得到了升力风扇垂直起降飞机的典型阻力特性曲线,并分析了全机总体参数对于过渡态阻力峰值的影响关系,进而得到了关于升力风扇垂直起降飞机总体布局设计的相关指导原则。
The introduction of the full paper discusses relevant matters and then proposes the analysis mentioned in the title. Sections 1 through 3 explain our analysis of the drag characteristics. We believe that all the results of our analysis can serve as effective guidelines for configuration design of lift-fan VTOL. Their core consists of： （ 1 ） we establish the aerodynamic estimation model of the lift-fan VTOL; （2） we ters on the peak drag of the lift-fan VTOL in its transition mode. Section shown in Figs. 2 through 10 in section 3 and three effective guidelines for analyze the effects of conceptual parame- 4 presents five conclusions for the results the configuration design of lift-fan VTOL.
