Flow Control for Loads Control

Abstract

During gust encounters and turbulence aircraft are subject to extreme loads that dictate the structural requirements. Amelioration of these loads would allow reduced structural weight and therefore greater efficiency. Flow control is used for controlling the extreme loads at the fluid-structure interface. Two versions of the jet flap, normal and upstream blowing from the upper surface are studied under steady state conditions to illustrate the effectiveness of these devices at mitigating lift loads. The upstream blowing jet flap is further investigated through periodic and transient activation to demonstrate the feasibility for controlling transient gust encounters. These measurements include force, pressure and Particle Image Velocimetry measurements at a Reynolds number of 660,000 for a NACA 0012 airfoil.
