Re-entry science in the 60s

October 18th, 2011

From the NASA NIX server:

Aerodynamic Heating and Deceleration During Entry into Planetary Atmospheres. Dr. Chapman’s lecture examines the physics behind spacecraft entry into planetary atmospheres. He explains how scientists determine if a planet has an atmosphere and how scientists can compute deceleration when the atmospheric conditions are unknown. Symbols and equations used for calculations for aerodynamic heating and deceleration are provided. He also explains heat transfer in bodies approaching an atmosphere, deceleration, and the use of ablation in protecting spacecraft from high temperatures during atmospheric entry.
