title = "Heat Transfer Study of a Conically Shaped Hypersonic Vehicle in Glide",
abstract = "A hypersonic boost-glide trajectory is calculated for an initial altitude of 60 km and a velocity after boost of 3.7. The hypersonic vehicle travels 2750 km before it reaches its destination over a flight time of 21.75 minutes. The aeroheating effects of a conically shaped hypersonic vehicle on the re-entry trajectory is calculated using a semi-empirical model for the surface heat flux. The maximum heat flux value is calculated to be 4 at the stagnation point. The H2 vehicle surface temperature is coupled with the surface heat flux and has a maximum of 2980 K. Several materials are considered for the hypersonic vehicle and it is shown that those with a high thermal conductivity lead to reductions in the vehicle surface temperature. Comparisons of the semi-empirical model with simulations ran using ANSYS FLUENTTM show that the calculated heat flux and vehicle surface temperature agree within ±30% of the simulated values. The maximum heat flux from the simulations is 4.42 maximum of 3047.2 K.",
