S.P. : An Aerodynamics in Relation to an Aeroassisted Orbit Transfer Vehicle}, month = {Nov}, note = {By using a free-piston, double-diaphragm shock tube, strong shock waves around 10 km/s are generated in air of initial pressure 13.3 Pa, corresponding to the flight regiems of AOTV. A system of automatic valve is developed to remove the diaphragm between high-pressure and compression chambers, and its usage results in remarkable improvement for reproducing shock waves with the same strength in the test section, The measured risetime of radiation intensity behind the shock front, as well as the duration of light emission, exhibits good agreement with the data obtained by Allen et al.[2]. Radiation profiles and ion-probe outputs are observed in the center of cross section of the tube and near by the wall. The results show that the contact zone is retarded near by the wall due to effect of boundary layer, though appreciable differences are not observed for front structures., 資料番号: SA0033605000}, pages = {15--25}, title = {Generation and Observation of Strong Shock Waves in the Flight Regiemes of AOTV}, volume = {7}, year = {1988} }
