FEASIBILITY OF A HIGH PERFORMANCE AERODYNAMIC IMPULSE FACILITY.
Abstract
A study was conducted to ascertain the feasibility of a high performance aerodynamic impulse facility capable of producing a high velocity and high Reynolds number environment. Of many facilities considered, those most promising were magnetic annular arc tunnels and expansion tubes as single stage techniques, and a shock tunnel driving a j x B accelerator as a two stage technique. Experimental performance of the Magnetic Annular Arc (a new device for this application) implies that it can achieve the environment considered, but research directed more specifically to this goal must be performed. The expansion tube can theoretically achieve the conditions required, but experimental results indicate the prohibitive lengths and energies above 10 to the 8th power joules will be required to achieve the times necessary for aerodynamic testing. The shock tunnel driving a j x B accelerator necessary to achieve the environment will be physically large and consequently require above 10 to the 8th power joules energy, but experiments thus far indicate no limitations which will prevent attainment of the desired environment.
