Abstract In order to accurately predict the thermal environment of hypersonic vehicles, many scholars have devoted themselves research related aerodynamic heating characteristics which provides important solutions for design protection systems. An IPID controller is designed aerothermal ground simulation system vehicles complete target tracking.

The accurate prediction of laminar-turbulent transition in hypersonic boundary layers is a critical part of the aerodynamic heating analyses on hypersonic vehicles. Despite decades of extensive research, the prediction of hypersonic boundary-layer transition is still mostly based on empirical correlation methods or the semi-empirical n e method because a number of physical mechanisms leading to...

SUMMARY The effect of heat conduction of material on the temperature distribution in the vicinity of a wing leading edge in hypersonic flight is investigated. The theory is based on a conducting plate subjected to aerodynamic heating. It is found that the role played by the conductivity of the materiel and the leading edge thickness in moderating the nose temperature is very significant. Detail...

For lifting entry vehicle, angle of attack is one of the most important trajectory control inputs. This paper aims to develop a practical and effective method for angle of attack design. First, the factors which impact angle of attack are analyzed. The entry flight is discussed as equilibrium glide phase and initial diving phase respectively. And the operation zone of angle of attack is obtaine...

This study investigates the flowfield patterns and distributions of surface heat flux due to interactions among three-dimensional shock waves at junction body wing an aircraft by solving Reynolds–averaged Navier–Stokes equations a Mach number 10 attack angles ranging from 5° 20°. The results indicate that structures wing/body-shock vary significantly with test conditions. Four types interaction...
