Hypercone inflatable supersonic decelerator

The need for an efficient supersonic decelerator arises first for use in aero-braking planetary landers, but may also have other uses such as spacecraft crew escape and aerocapture of orbital planetary probes. Hypercone is a
concept currently under investigation for use in such applications. The paper,  Hypercone Inflatable Supersonic Decelerator was authored by: Glen J.
