Abstract:

A literature review on planetary atmospheres is presented. The ranges of atmospheric scale heights for Mars and Venus are noted and their subsequent effects and uncertainties in heating and loads discussed. Simplified relationships are developed for laminar and turbulent heat transfer and loads that are adequate for preliminary investigations of ballistic vehicle entries into the atmospheres of Venus and Mars. Comparison of the heat transfer predictions with a limited amount of experimental data is included. Author
