摘要:

依托航空工业空气动力研究院FL-8低速风洞,围绕常规和翼身融合布局水上飞机带滑流影响的吹气流动控制效能和机理开展风洞试验研究,试验采用小尺寸半模模型和外式空气桥天平,通过小体积大功率直流电机驱动螺旋桨模拟滑流动力影响,通过外接高压气源和多级流量控制模块进行舵面吹气系统流量的精确控制。试验验证了相关试验方法和设备的可靠性,获得了螺旋桨滑流、吹气流动控制以及两者耦合后对水上飞机升力特性的综合影响,通过流动显示方法研究了滑流、吹气以及两者耦合影响的流动机理。试验结果表明:常规布局和翼身融合布局机械增升效果有限,单独附加襟翼吹气控制后增升效果明显改善,当吹气动量系数Cμ =0.12时,飞机最大升力系数CLmax相比机械增升构型最大增加45%;单独滑流动力影响可以大幅提升飞行器的升力,当螺旋桨拉力系数CT =0.45时,飞机CLmax相比机械增升构型最大增加137%;当滑流影响和吹气控制耦合作用后,飞机CLmax相比机械增升构型最大增加176%,其中常规布局耦合效果小于单项叠加之和,翼身融合布局耦合效果大于单项叠加之和。

Abstract:

Relying on the FL-8 low-speed wind tunnel of AVIC Aerodynamics Research Institute, wind tunnel test research was conducted on the control efficiency and mechanism of blowing flow control with slipstream influence around conventional and blended wing-body layout seaplanes. The test utilized a small-scale half-model and an external air bridge balance. A small-volume high-power DC motor was used to drive a propeller to simulate the influence of slipstream, and an external high-pressure air source and a multi-stage flow control module were used to precisely control the flow of the flap surface air blowing system. The test verified the reliability of the relevant experimental methods and equipment, and obtained the comprehensive impact of propeller slipstream, blown air flow control, and their coupling on the lift characteristics of seaplanes. The flow mechanism of slipstream, blown air, and their coupling effects was studied through flow visualization methods. The test results indicate that the mechanical lift enhancement effects of the two layouts are limited. The lift enhancement effect is significantly improved after the addition of flap blowing control alone. When Cμ =0.12, CLmax increases by a maximum of 45% compared to the mechanical lift enhancement configuration. The influence of slipstream power alone can greatly enhance the lift of the aircraft. When CT =0.45, CLmax increases by a maximum of 137% compared to the mechanical lift enhancement configuration. When the slipstream influence and blowing control are coupled, CLmax increases by a maximum of 176% compared to the mechanical lift enhancement. The coupling effect of conventional layout lift enhancement is less than the sum of individual effects, the coupling effect of blended wing-body layout lift enhancement is greater than the sum of individual effects.
