Abstract
1,213,551. Generating combustion products under pressure. ROLLS-ROYCE Ltd. June 6, 1969 [June 14, 1968], No.28389/68. Heading F1L Combustion apparatus 10 comprises a toroidal combustion chamber 12 around which rotate continuously combustion initiating detonation waves, and means for successively supplying a region of the chamber, between the passage of successive wave crests therepast, with a supply of a gaseous oxidant followed by a supply of a detonatable mixture of the oxidant and of a fuel, the oxidant forming a barrier layer between the combustion gases and the mixture to prevent pre-ignition. The combustion chamber 12 has inlet and outlet ducts 13,14 respectively, the duct 13 communicating with a mixing chamber 16. The latter is connected through annular ducts 20, 21 with annular fuel and oxidant manifolds 22, 23 respectively. The fuel manifold 22 contains atomized kerosene or gaseous methane, ethylene or hydrogen and the oxidant manifold 23 contains air, oxygen – enriched air or pure oxygen. Rotation of the detonation waves around the combustion chamber 12 is initiated by an igniter 15. At any point of the chamber 12 the pressure reaches a maximum value (e.g. 150p.s.i.) when a detonation wave crest passes that point and then falls off until the next wave crest arrives. Since the oxidant in manifold 23 is maintained at a higher pressure (e.g. 60 p. s. i.) than the fuel in manifold 22 (e.g. 30 p. s. i. ), oxidant enters the combustion chamber 12 when the pressure at a point behind a detonation wave crest has fallen below the oxidant pressure. When the pressure has fallen still further to below the fuel pressure a mixture of fuel and oxidant enters the chamber 12 and subsequently ignites. The oxidant admitted prior to the mixture thus prevents pre-ignition by providing a barrier layer between the mixture and the combustion gases.
