Regimes of continuous detonation of heterogeneous mixtures of aviation kerosene and air are obtained for the ¦rst time and studied in
a §ow-type annular cylindrical chamber 503 mm in diameter with
variations of its geometry: air supply slot, kerosene injectors, and
combustor geometry. The air §ow rate is changed in the interval
8.433.7 kg/s, the kerosene §ow rate is changed in the interval 1.38
2.05 kg/s, and the equivalence ratio is changed from 0.88 to 2.8.
Kerosene is bubbled with air. Regimes of continuous multifront detonation (CMD) are observed in the case of combustor duct constriction
at the exit. Based on the pressure measured at the combustor exit,
speci¦c impulses are determined. The maximum speci¦c impulse with
allowance for the energy of compressed air in the receivers is approximately 1400 s.
