Two kinds of multi-nozzles, one consisting of four and the other of seven nozzles, were used. The measurements include radial distributions of Pitot pressure and gas composition at the secondary combustor exit, axial wall pressure distribution, and air stagnation pressure. The results were compared with those previously obtained in an experiment using a single nozzle, and the influence of number of nozzles, N, on the relation between length and performance of the secondary combustor was investigated. Despite the distortion of the individual exhaust jets from the multi-nozzle, combustor length for sufficient performance was found to be proportional to the diameter of rocket nozzle exit or 1/the root N., 資料番号: NALTR0728000, レポート番号: NAL TR-728}, title = {空気吸込式ロケットの研究(II)-ロケットノズル数の影響-}, year = {1982} }
