Transformable and Reconfigurable Entry, Descent, and Landing Systems and Methods

NASA has developed a game-changing deployable aeroshell concept for entry, descent, and landing (EDL) of large science and exploration-class payloads. The Adaptable, Deployable Entry Placement Technology (ADEPT) concept is a mechanically deployable semi-rigid aeroshell entry system capable of achieving low ballistic coefficient during entry suitable for a variety of planetary or Earth return missions. It leverages Ames expertise in Thermal Protection Systems (TPS) material and entry system design, development, and testing. The deployable decelerator systems offer a lighter-weight solution to current rigid, high-ballistic-coefficient aeroshells. The deployable feature of ADEPT allows each mission to utilize an entry system design that fits within existing launch vehicle systems, and later transforms into a low ballistic coefficient configuration for EDL. Consisting of rigid ribs and a TPS, deployment can be done for inspection in Earth orbit by extending the ribs and stretching the TPS in between (in a method similar to an opening umbrella), and thereby reducing the mission risk.
