As NASA missions to Mars progress with science and complex human exploration missions, spacecraft will require larger heat shields to protect against the extreme heat of entering a planet’s atmosphere and decelerating at a safe altitude in the thin Martian atmosphere.
Today’s rockets have limited space to accommodate spacecraft and their heat shields. However, engineers at NASA’s Ames Research Center in Silicon Valley, California, have a solution to accommodate that limitation.
NASA’s Adaptive Deployable Entry and Placement Technology (ADEPT) is one solution. ADEPT is a mechanically-deployable heat shield concept using carbon fabric: a flexible heat shield that expands to “open” like an umbrella. Recently, Ames’ engineers
Surface temperatures on the test article reached 3,100 degrees Fahrenheit. The bluish-hue streaks, streaming away from the test article, are due to the decomposition of the resin-infused protective layers that prevent degradation of the stitched fabric joints.
Extensive instrumentation and imaging products from the test will be used to validate how materials respond to the testing conditions, and thermo-structural design codes. The testing approach demonstrated with this test will enable future, more extensive testing of the ADEPT configuration – toward possible future use of the system on missions bigger than anything NASA’s ever flown.
The ADEPT project is led by NASA’s Ames Research Center, with contributions from multiple other NASA centers. Testing, conducted by Ames’ Entry Systems and Technology Division, was funded by the Game Changing Development Program within NASA’s Space Technology Mission Directorate.
