Abstract

745,693. Controlling boundary layer. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 31, 1951 [Jan. 4, 1951], No. 23600/53. Divided out of 745,630, [Group XXVI]. Class 4. [Also in Group XXVI] A device for controlling the flow of a gaseous fluid between adjoining blades of cambered shape, disposed in a row such as in a turbine or compressor, comprises nozzle means on said blades opening out on the concave surface thereof and directed towards the convex surface of the next successive blades in said row, said nozzle means being fed with gaseous fluid under pressure, the flow of which is controlled by valve means. The blades 21 are stator blades and the blades 21a rotor blades, a cavity 19 in each blade being supplied from a common source with gas under pressure, the rate of flow of the gas being made dependent on the operation of the turbine or compressor by the operation of a controllable valve (not shown). The direction of the nozzle 20 of each cavity 19 may be inclined with respect to the portion of blade surface surrounding it in order to control the boundary layer flow over the convex surface of the adjoining blade or it may be substantially normal to such surface in order that the rate of flow of the operating fluid through the blading may be controlled.
