Scott Manley | How NASA Tests Heat Shields Using a Plasma Wind Tunnel @scottmanley | Uploaded 2 months ago | Updated 4 days ago
At NASA Ames Research Center in California there is a specialized wind tunnel facility known as the ArcJet complex. This is for testing heat shields on spacecraft, high temperature, highly ionized plasma is created by heating the air with an electric arc, and then the high pressure plasma flows out a rocket nozzle at hypersonic speeds into a test chamber where samples of thermal protection material are tested.
