A study has been performed to determine the optimum, practical high-energy driver technique to be employed with the Air Force Aero Propulsion Laboratory 120-inch shock tunnel. The aerodynamic performance and engineering design and feasibility of several candidate techniques have been investigated. An internally and statically heated, 6-inch ID driver tube, employing hydrogen at a maximum pressure of 30,000 psi and a maximum temperature of 1000 F is recommended as the optimum, practical system. Such a driver will provide true speed, pressure, and temperature simulation along the corridor. Moreover, the engineering design of the heater, seals, diaphragm, and safety system are all within the current state-of-the-art, while the problem of hydrogen embrittlement of the driver tube appears solvable.
