A concept of multi-jets flow control was proposed for a hypersonic reentry vehicle. The high pressure air behind the bow shock flowed into the tunnel through the multihole head
and then sprayed out through the downstream multi-jets arrays. The 3-D Reynold-averaged Navier-Stokes (RANS) simulations based on Fluent software were conducted to study the effect of multi-jets configuration at Mach number of 6
height of 25km. The results showed that the multi-jets flow induced a drag coefficient increment for both the side-hole down-bottom (SH-DB) case and the side-hole upper-bottom (SH-UB) case. The increment of lift coefficient and head-down moment was observed for the SH-DB case
and the decrement of lift coefficient and head-up moment was observed for the SH-UB case. This study provides a method of using non-movement aerodynamic control surface to produce control moment
and also a reference for combination control of hypersonic reentry vehicle.
