aeroshell
Noun
Meaning
aeroshell (plural aeroshells)
An aerodynamic shell that protects a spacecraft during travel from lift-off through the atmosphere from aerodynamic forces
Examples
An inflatable aeroshell provides one alternative for enlarging the drag area with a low-mass design.
Based upon Allen and Eggers discovery, maximum aeroshell bluntness (maximum drag) yields minimum TPS mass.
In November 1964, von Braun proposed a more ambitious plan to build a much larger station built from the S-II second stage of a Saturn V. His design replaced the S-IVB third stage with an aeroshell, primarily as an adapter for the CSM on top.
It is incorrect to reapply an aeroshell design intended for Titan entry ( Huygens probe in a nitrogen atmosphere) for Mars entry ( Beagle-2 in a carbon dioxide atmosphere).
PICA was patented by NASA Ames Research Center in the 1990s and was the primary TPS material for the Stardust aeroshell.
The MSL aeroshell TPS is currently designed to withstand a peak heat flux of 234 W/cm².
