Blunt body reentry
WebAll spacecraft use blunt-body geometry to survive reentry. The space shuttle has a complex geometry, but it behaves essentially as a blunt-body reentry vehicle during the most intense part of reentry. The shock waves that form are crucial for protecting the shuttle. The shuttle enters the atmosphere with the blunt underside of WebSpace Shuttle Discovery as it approaches the International Space Station during the STS-114 on 28 July 2005. The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the searing 1,650 °C (3,000 °F) heat of atmospheric reentry.

GOAL: I'm trying to get a first-pass analytical approximation for the lift and drag coefficients for hypersonic flow over a blunt-body capsule spacecraft (similar to NASA's Apollo or SpaceX's Dragon) during atmospheric reentry from LEO.
WebDec 7, 2009 · H. Julian Allen is best known for his "Blunt Body Theory" of aerodynamics, a design technique for alleviating the severe re-entry heating problem which was then delaying the development of ballistic missiles. His findings revolutionized the fundamental design of ballistic missle re-entry shapes.

Practical development of reentry systems began as the range, and reentry velocity of ballistic missiles increased. For early short-range missiles, like the V-2 , stabilization and aerodynamic stress were important issues (many V-2s broke apart during reentry), but heating was not a serious problem.
