A Review of Flow Control for Gust Load Alleviation

Effective control of aerodynamic loads, such as maneuvering load and gust load, allows for reduced structural weight therefore greater efficiency. After a basic introduction in the types gusts current strategies aircraft, we outline conventional alleviation techniques using trailing-edge flaps spoilers. As these devices also function high-lift or inflight speed brakes, they are often too heavy high-frequency activations surfaces. Non-conventional active via fluidic actuators have attracted some attention recently from researchers to explore more effective against traditional future aircraft design. Research progress flow actuators, including surface jet blowing circulation (CC) alleviation, is reviewed detail here. Their capabilities terms lift force modulations outlined compared. Also performances under conditions. Experiments numerical efforts indicated that both CC demonstrate fast response characteristics, capable timely adaptive controls.
