摘要

采用射流控制可以有效增加飞机升力、改善起降性能，而地面效应是分析飞机起降性能必须要考虑的因素。为了研究地面效应对射流增升翼型气动性能的影响，通过表面压力测量和PIV流场测量，详细对比研究了无射流条件下基本翼型、定常射流控制翼型及脉冲射流控制翼型在地面效应影响下的气动性能和流场特性。研究表明：受地面效应影响，基本翼型和射流增升翼型升力线斜率降低，升力减小，失速提前；有无地面效应时，脉冲射流的增升效果都大于定常射流；相同的射流动量系数下，距地越近，分离控制效果越差，升力也越小。

Abstract

The lift can be effectively increased and the take-off and landing characteristics can be greatly improved by using blowing control

while ground effect must be considered when analyzing the performance of take-off and landing. In order to investigate the ground effect of the airfoil using blowing to enhance lift

the aerodynamic characteristics of the basic airfoil

steady blowing control airfoil and pulse blowing control airfoil are experimentally investigated by surface pressure and PIV flow field measurement. The results show that the lift coefficient and the lift coefficient slope of the basic airfoil and the blowing control airfoil decrease in ground effect

the separation restrain ability of pulse blowing control is stronger than that of steady blowing with and without ground effect

and the lift enhancement is smaller with ground effect than that without ground effect using pulse blowing at the same control conditions.
