One key feature that distinguishes the flowfield around vehicles flying in supersonic and
hypersonic regimes is the bow shock wave ahead of forebody. The severe drag and …

Blunt-nose body structures are widely used in vehicles for better heat distribution due to
supersonic/hypersonic flight. However, such a body shape contributes to an increase of …

Vehicles flying at supersonic/hypersonic speeds would encounter severe aerodynamic and
aerothermodynamic environment, and hypersonic vehicles would produce high pressure …

In this study, the drag force and aerodynamic heating reduction capacity of a novel
combined spike root jet and multi-row disk (SRJ-MRD) model consisting of a blunt body, a …

By slotting an inlet at the head of the aerodisk, a channel through the spike, and the lateral
jet outlet at the middle of the spike, the blunt body with spike-aerodisk can further reduce its …

The drag reduction and thermal protection mechanism induced by the spike and its
combinations with jet strategy is investigated in the current study. A fluid-thermal coupled …

For the drag and heat flux reduction of hypersonic blunt body, a novel combinational spike-
aerodisk and channel concept has been proposed. The high pressure air behind the bow …

Scramjet is one of the most promising propulsion systems for the new generation
supersonic/hypersonic air-breathing flight vehicles. To achieve sufficiently high combustion …

Enhancing the combustion efficiency of gas fuel, ie, hydrogen, in supersonic reacting flows
has attracted wide attention around the world, besides, the flame holders are the key …

This paper presents numerical analyses of lateral jets in hypersonic flow injected at the
blending area of a reusable launch vehicle. The simulation is performed utilizing the three …
