タイトル（掲載誌）航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-573
一般注記Subsonic(downstream choking) mode combustion in cylindrical secondary combustors of air breathing rockets was investigated. Two different types of experimental apparaturs(A and B) were used. Apparatus A inhaled atmospheric air using ejector exhaust system, so that the air stagnation pressure was kept at a constant one atmosphere. In apparatus B, compressed air was supplied to the secondary combustor, in order to keep air flow rate constant. Axial wall pressure distribution, air flow rate(in apparatus A) or air stagnation pressure(in apparatus B), and the radial distribution of Pitot pressure and temperature(only in apparatus A) at the exit of the secondary combustor were measured. These experimental results were compared with ideal conditions at the exit and the air inlet of the secondary combustor, which were then calculated on the assumption of the complete mixing and burning primary rocket exhaust and air stream. A one-dimensional analysis with the measured wall pressure distribution made it possible to calculate axial distribution of other properties such as Mach number, stagnation temperature, and so on. From the stagnation temperature distribution in a sufficiently long secondary combustor, we determined “effective flame length”lf and used it as a measure of necessary combustor length. The performances of the secondary combustors were well correlated to the non-dimensional combustor length, L/lf.
