Abstract:

The preliminary design of 8.5-inch ID, statically and internally heated hydrogen or helium shock tunnel driver is described. The driver is designed for a maximum performance of 1000 degrees F and 30,000 psi and will provide true temperature and pressure simulation of the air breathing propulsion system corridor. The heat transfer from the heater rods is considered and the results used to calculate the heating cycle and the temperature distribution history of the driver structure. A heating time of from one to two minutes is predicted. A preliminary design of the driver is presented which employs a liquid layer between the potentially embrittleable driver liner and the pressure shell. The temperature distribution predictions are employed to calculate the combined thermal and mechanical stresses in the structure. Finally, the preliminary design of the heater structure, liquid layer, seals, and double diaphragm section is given. Author
