スクラムジェットエンジンのマッハ6燃焼試験 -ストラットと分離部の効果について- Mach 6 Combustion Tests of a Scramjet Engine -Effect of Strut and Isolator-
The main purposes of this study are to investigate the effect of strut configurations and isolator length within the engine on the engine performance at Mach 6 condition, and to determine performance of the engine by gas sampling at the exit plane. The sub-scale scramjet engine had an overall length of 2, 100mm, height of 250mm and width of 200mm and was tested at the RamJet engine Test Facility (RJTF) of the Kakuda Research Center, NAL. In the tests were ompared the effects of strut configurations in an engine with a 200-mm long isolator on the engine performance. The thrust as measured along the fuel flow rate, and the fuel distribution at the engine exit plane was measured by means of gas ampling. It was found that the strut configuration had an effect on the thrust performance, that the 200mm-long isolator as effective in preventing combustor/inlet interaction in the engine with full-height strut, and that the fuel distribution in he engine was not uniform which affected the thrust performance. The maximum thrust obtained was 1620 N at the fuel low rate of 70g/s (the bulk equivalence ratio of 0.4).
