Title: Improvements in or relating to ducted-fan gas turbine jet propulsion engines
Inventor: SCHMITT HEINZ EUGEN
IPC: F02K1/16
Filed: 1959-12-07
Abstract: 875,496. Gas turbine jet propulsion plant. GENERAL ELECTRIC CO. Dec. 7, 1959, No. 41473/59. Class 110 (3). A ducted fan gas turbine jet propulsion engine comprising a gas turbine engine disposed within a substantially cylindrical outer casing to form a by-pass duct which is provided with combustion means and an exhaust nozzle, has control vanes to control the air flow to the gas turbine engine to permit selective operation of the engine as a ducted fan engine or as a ram jet and means to vary the configuration of the by-pass exhaust nozzle in accordance with the position of the control vanes. A compressor 10 supplies combustion air to combustion equipment 11 feeding a turbine 12 driving the compressor. The exhaust of the turbine 12 is used to drive a turbine 14 before passing through a duct 20 which terminates in a convergent nozzle 24. The turbine 14 drives fan blades 15 arranged in a duct 16 formed by a casing 17 extending around the inner casing 18. Combustion means 27 is provided in the duct 16. The compressor 10 has control vanes 13 to control the air admission to the compressor which vanes are connected through linkage 23 to an actuator 21 which moves the duct 20 axially. The duct 20 has protuberances 26 which co-operate with protuberances 25 on the casing 17 to form a variable-area nozzle. At take-off and low Mach numbers, the vanes 13 are open and the duct 20 on the position shown. Since the area at X is less than that at Y, the nozzle is convergent. At Mach numbers between 2 and 3 the fuel supply to the combustion equipment 11 is gradually reduced until it is shut off. The vanes 13 are then closed. The entire air flow now passes through duct 16 and the effective area of the propelling nozzle thereby reduced by the amount W. As the area of W is half that of X the area is reduced by one third. To further reduce the area at high Mach numbers the duct 20 is retracted so that the protuberances 25 to 26 become opposite one another which further reduces the effective throat area and also forms a convergentdivergent nozzle.

[Also in Division E1] A brick or other building block is formed from compressed gypsum mixed with a suitable binding agent and is completely encapsulated with an impervious layer of a flexible synthetic plastics material. The binder may be a synthetic resin such as "Araldite" (the word "Araldite" is a Trade Mark). The gypsum binder may be pressed to the required dimensions in known manner, and opposite faces of the brick may be formed with complementary projections and recesses at corresponding positions. These formations may be arranged in one or more longitudinal rows and are conveniently pyramidal. Alternatively the gypsum binder may be forced through a rectangular orifice and suitable lengths cut from the resultant bar by forcing wires through the plastic mass. The building block may take the form of a slab with a rib and complementary groove along opposite edges, and may be moulded with through holes in the thickness thereof so that a wall built from such blocks will be ventilated. The holes may also be used to accommodate reinforcing rods which after erection of the wall can be grouted in position. The encapsulation may be effected by dipping the formed brick in polyurethane dissolved in trichlorethylene. The bricks may be used only for the partition walls of a building and for the inner faces of its cavity walls, the outer faces of the latter being built on conventional bricks and tied to the inner faces in known manner.
