水上飞机缩比模型带滑流影响的吹气控制试验
Blowing flow control test of seaplane scaled models with slipstream effects
摘要
Abstract
Relying on the FL-8 low-speed wind tunnel of AVIC Aerodynamics Research Institute,wind tunnel test re-search 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 ex-ternal air bridge balance.A small-volume high-power DC motor was used to drive a propeller to simulate the influ-ence of slipstream,and an external high-pressure air source and a multi-stage flow control module were used to pre-cisely control the flow of the flap surface air blowing system.The test verified the reliability of the relevant experimen-tal 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 en-hancement effects of the two layouts are limited.The lift enhancement effect is significantly improved after the addi-tion of flap blowing control alone.When Cμ=0.12,CLmax increases by a maximum of 45%compared to the mechani-cal lift enhancement configuration.The influence of slipstream power alone can greatly enhance the lift of the air-craft.When CT=0.45,CLmax increases by a maximum of 137%compared to the mechanical lift enhancement con-figuration.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.关键词
