Application Research of Flow Control Using Co-flow Jet on a Vertical Tail

Hangkong gongcheng jinzhan, 2022
The aerodynamic characteristics of the vertical tail of an aircraft are directly related to the size and weight of the vertical tail. Increasing the lift force of the vertical tail using flow control can further reduce the size of the vertical tail,which
