Abstract Aerodynamic heating and temperature distribution are one of the problems that must be considered in design hypersonic rocket sled. In order to evaluate aerodynamic environment sled, typical monorail sled with cone cylinder combination is taken as research object, calculation methods such Modified Newton Theory, Reynolds Analogy Reference Enthalpy Method Fourier’s Law Heat Conduction us...

This work is an example of application of nonlinear programming to a problem of three-dimensional trajectory optimization for multistage launch vehicles for geostationary orbit missions. The main objective is to minimize fuel consumption or equivalently to maximize the payload. The launch vehicle considered here, Europa-II, consists of 5 thrust phases and 2 coast phases. Major parameters of the...

The design of the thermal protection system requires high-precision and high-reliability CFD simulation for validation. To accurately predict hypersonic aerodynamic heating, an overall strategy based on mutual selection is proposed. Foremost, grid criterion wall cell Reynolds number developed. Subsequently, dependence turbulence model discretization scheme considered. It suggested that appropri...

The aerodynamic heating environment with ablation injection and the mass loss rate of the ablator under the superorbital re-entry condition of the MUSES-C sample return capsule are numerically studied by solving the viscous shockIayer (VSL) equations with the nonequilibrium chemistry of both the air and the ablation gas. The boundary conditions at the ablator surface are formulated by consideri...
