Abstract
782,396. Jet-propulsion plant. ZBOROWSKI, H. P. G. A. R. VON. Aug. 18, 1955 [Aug. 20, 1954], No. 23775/55. Class 110 (3). [Also in Group XXXIII] A ram jet has a variable area propelling nozzle controlled by means responsive to the difference in static pressures on the inside of the inlet diffuser and on the outside of the engine so that this difference remains substantially constant. The ram jet shown has a casing 1 formed as a body of revolution containing two annular burners 2. The casing may constitute the main supporting aerodynamic surface of the aircraft. The area of the propelling nozzle 3 is controlled by spoilers 4 actuated by a servomotor 14 through a link 15. The servomotor 14 is controlled by a detector comprising a box having a diaphragm 8 which divides it into two chambers connected by passages 9, 10 with the inside of the inlet diffuser 7 and the outside of the engine respectively. The diaphragm 8 carries an insulating button 11 capable of closing either of two electric switches 12, 13 which energize the servomotor 14. Closing of switch 12 due to reduction of pressure in the diffuser 7 causes a throttling of the propelling jet and closing of switch 13 causes an increase in the crosssection of the jet. The contacts 12, 13 may be mounted on a movable support controlled by a machmeter or a device responsive to the static pressure or the translational speed of the engine or both so that the control only acts above a given static pressure difference, the value of which varies with these engine operating conditions. A second control system may be provided to act independently on the spoilers 4 to produce a deflection of the jet. In a modification, the area of the propelling jet is varied by controlling air passages through the casing 1. If desired, the area of the propelling nozzle, may be varied by pivoting shutters or by introducing air under pressure into the jet, which air may be supplied by a special compressor, by another engine on the aircraft such as a turbojet, or turbo-propeller engine, or by the air flow through the ram jet.
