Atmospheric Entry Simulator

(c. 1956) Alfred Eggers, Jr., standing beside the Small-Scale Atmospheric Entry Simulator, a pilot counterflow ballistic tunnel built to validate his concept that a model shot through air that was flowing in the opposite direction through a hypersonic nozzle would simulate the conditions a spacecraft might encounter re-entering the Earth’s atmosphere. Its successful operation led to the construction of the larger, faster Atmospheric Entry Simulator.
