Abstract
1,140,563. Air cushion vehicles. DOWTY ROTOL Ltd. 4 April, 1966 [14 April, 1965], No. 16054/65. Heading B7K. [Also in Divisions F1 and G3] An air cushion vehicle has at least one compressor of rotodynamic type suitable for providing the air cushion and/or propulsive thrust for the vehicle, and the rotor of the or each compressor includes adjustable blading, adjustment of which during operation affords variation in delivery pressure and mass flow without the need to change the rotational speed. The air cushion vehicle shown in Fig. 1 has at least one centrifugal or axial-flow compressor 14 to provide the air cushion and driven through a bevel gear-box 20 by a gas turbine engine 15 which also drives a propeller 16. The compressor 14 has variable-pitch impeller blading (see Division F1) and the propeller 16 may also be of variablepitch type, whereby the thrust of the compressor and of the propeller can be varied independently without alteration of rotational speed. Two or more compressors may be provided so that slight changes of attitude of the vehicle can be made by differential adjustment of their blade pitch. The propeller may be replaced by a further ducted compressor or by using the aircushion compressor for propulsion also.
