Abstract
680,717. Jet propulsion plant. DE HAVILLAND ENGINE CO., Ltd.. HALFORD, F. B., CLEAVER, A. V., and DOVE, E. B. Aug. 22, 1950 [July 14, 1949], No. 18568/49. Class 110(iii) [Also in Group XXIX] In a rocket motor wherein propellents are pumped into a main combustion chamber 10 and ignited by the products of combustion issuing from a pre-combustion chamber 13, an oxygen bearing gas or vapour is produced for driving the propellent pumps and a portion of the gas or vapour constitutes one of the combustible substances fed to the pre-combustion chamber. A valve 12, for controlling the supply of propellents to the combustion chamber 10, is supplied with hydrogen peroxide and fuel by pumps 15, 21 through pipes 16-19 and 22-24 respectively. The pumps are driven by a turbine 25 actuated by the decomposition of hydrogen peroxide in a generator 26. The generator 26 is recharged with hydrogen peroxide through a valve 33 controlled by a governor 36 on the turbine shaft. The pumps are primed by ejectors 39, 40 which are actuated by hydrogen peroxide drawn off through pipes 41, 42 respectively and are cut out on contact with the resulting delivery. The pre-combustion chamber 13 is supplied with hydrogen peroxide through pipes 27, 45 which have a pressure responsive valve 43 and a pressure responsive element 46 respectively. Fuel is fed to the chamber 13 through an igniting valve 58 and a pipe 28 and is fed to the valve 12 through a valve 59 which is controlled by the element 46. The first and second stage injectors of the combustion chamber 10 receive fuel and hydrogen peroxide through pipes 60, 61 and 52, 53 respectively. A lever 38 controls the governor 36, the valve 58 and the valve 12 which may incorporate the valves 58. 59. Specification 680,718 is referred to.
