Abstract
Regimes of continuous detonation of aviation kerosene and air mixtures are obtained for the first time and studied in a flow-type annular cylindrical chamber 503 mm in diameter with variations of its geometry. The air flow rate is varied in the interval 8.22–33.95 kg/s and the kerosene flow rate is varied in the interval 1.39–2.05 kg/s, producing an equivalence ratio in the range of 0.85–2.8. In the fuel injection system, kerosene is bubbled with air. Regimes of continuous multifront detonation are observed in the case of combustor duct constriction of the exit of three times. Regimes with four counter-rotating detonation waves with mean rotation velocity of 1.02–1.22 km/s and rotation frequency of 2.59–3.09 kHz are observed in the case with the air injection slot of 3.5 mm. Regimes observed for an air injection slot of 10.5 mm have two counter-rotating detonation waves with the mean rotation velocity of 0.79–0.87 km/s and rotation frequency of 1.0–1.1 kHz. The influence of the flow rate of the kerosene–air mixture and the combustor geometry on the detonation operating range is analyzed. It is shown that an increase in the slot width in the case of critical exhausting of the products from the combustor leads to subcritical injection of air into the combustor and, hence, to the reduction in hydraulic losses of the flow. Based on the pressure measured at the combustor exit, thrust force and specific impulses are determined. The maximum specific impulse, taking into account the energy of compressed air in the supply tanks, is approximately 1400 s.
