Abstract
709,222. Jet propulsion plant. ENGINEERING CORPORATION, Ltd. July 18, 1951 [July 20, 1950]. No. 17024/51. Class 110(3) [Also in Group XII] In an intermittently-working ram-jet propulsion engine having a combustion chamber 2, the air inlet valve 3 is opened by aerodynamic pressure and is closed by combustion pressure, the outlet or discharge valve 6 being controlled on the air inlet valve by a member such as spring 17, and the discharge valve 6 is closed during combustion so that combustion occurs at constant volume. In Fig. 1 the inlet valve 3 slides on a piston 14 and is separated therefrom by the spring 17, the piston being secured on the hollow spindle 16 which slides in a guide 15 and carries at its other end the discharge valve 6. The valve 3 is opened by aerodynamic pressure and the valve 6 follows up the movement to close the discharge opening. Fuel is injected througli the injector 4 and combustion started by igniter 5, the resulting increase in pressure closing the valve 3. The valve 6 follows up the movement and allows the gases to pass to the nozzle 10. Air passing through the spindle 16 cools the spindle and valve 6 and provides a supplementary mass of air. The embodiment of Fig. 2 is similar to that of Fig. 1 except that the area of the rear surface 14 of the piston 14 is less than that of the forward surface 6' of the valve 6. When combustion occurs the inlet valve 3 slides forward on the piston 14 and closes the air inlet and at the same time allows the full combustion pressure to act on the rearward-facing surface 21 of the piston 14. As the area of the surface 21 is greater than that of the surface 6'. the discharge valve is caused to open suddenly. The engine may comprise a plurality of combustion chambers arranged in diametrically-opposed pairs.
