Effects of wall mass injection on drag and heat reduction characteristics of high-speed flight vehicles
Aiming at the development requirements of high lift-drag ratio and low thermal load of a new type of high-speed flight vehicle in the future
a large swept delta wing which is close to the practical engineering is chosen as the study object in this paper. Numerical simulations on the effects of large-area wall mass injection on the drag and heat reductions in flight states are carried out
and the influences of mass injection on the aerodynamic force and heat characteristics of delta wing under different flight altitudes
freestream Mach numbers
injection flow rates
injection temperatures and gas models are compared and analyzed. Based on the engineering requirements of drag and heat reductions of high-speed flight vehicles
the issues of wall mass injection in the engineering applications and the research directions that deserve more attention in the future are pointed out.
