摘要

短距起降运输机对增升装置提出了更高要求，常规机械式增升装置已无法满足，内吹式襟翼系统是当今固定翼飞机最有效的动力增升形式。为推动该技术的工程应用，基于雷诺平均N-S方程，对某加装60°偏角无缝襟翼的亚声速翼型在环量控制作用下的流场进行数值模拟，研究了其在不同吹气动量系数下的气动特性及流动形态，分析了不同环量控制阶段增升机理、失速特性和吹气动量系数对失速特性影响规律。结果表明：内吹式襟翼增升控制效率（升力系数增量与吹气动量系数的比值）较高，在临界吹气动量系数下可达70，此时相较于无吹气状态，升力增加约125%；主翼上由于环量增加产生的升力增量是翼型升力增量的主要来源，约占总升力增量的78%；吹气动量系数增加可造成翼型气动中心后移；附面层分离控制区主要通过消除襟翼上的流动分离增加升力，超环量控制区升力的增加是由于尾缘下游的射流效应使流线进一步偏转而实现的；随吹气动量增加，附面层分离控制区的失速迎角提前，超环量控制区失速迎角略微推迟。

Abstract

With the special demand of STOL performance for transport plane

the regularly mechanical devices for lift enhancement could no longer satisfy the requirement of maximum available lift coefficient. The internally blown flap system is the most efficient way of powered lift-enhancement for fixed-wing aircraft. In order to promote the engineering application of this technology

the aerodynamic characteristics and flow structure of a 2D subsonic 60° seamless flap with varying moment coefficient are obtained based on RANS equations. The mechanism of circulation control and stall in different regime have been analysed. It reveals that

the lift-enhancement efficiency (the ratio between the gain in lift yielded by the active system and the required blowing momentum) of this system is high

which reaches the highest value of 70 at the critical momentum

and the lift coefficient increase by 125% compared to that of without blowing. With blowing

the lift coefficient increases due to the circulation increases on the main wing surface

the increment is about 78% of the total lift coefficient increment. The location of aerodynamic center of the airfoil moves backward with the increase of blowing flux. Further

blowing delays flow separation at the boundary-layer control regime

resulting in a significant lift coefficient improvement. The increment of lift coefficient is achieved by a further defection of the streamlines due to the jet effect downstream of the trailing edge at the super-circulation regime. With the blowing flux increase

the stall angle decrease in the boundary layer regime and increase at the super-circulation regime.
