Abstract

754,579. Elastic-fluid turbines; turbinedriven fans. GARRETT CORPORATION. May 12, 1954 [June 1; 1953], No. 13865/54. Class 110(3) [Also in Group XXXIII] A turbine-driven fan comprises a stationary shroud structure disposed axially within a housing, a wheel rotatably mounted in the shroud structure and carry ing fan blades which are disposed within the passage formed between the shroud structure and the housing, nozzles for directing driving fluid into a diffuser carried by the wheel radially inwardly of the fan blades, and passage means within the fan blades for conducting the driving fluid through the fan blades and expelling it through the trailing edges thereof. Motive fluid, such as compressed air, passes through a duct 24 to a chamber 21 and thence through stationary nozzle blades 66, impinging on diffuser blades 60 carried by a wheel 41. After expansion in the diffuser, the air enters a chamber 64 from which it passes to the interior 50a of each fan blade 50. The air is exhausted as a propulsive jet through nozbles 54 at the trailing edge 53 of each blade 50. The wheel 41 is rotated partly by these propulsive jets and partly by the action of the air on the diffuser blades 60. The air exhausted from the nozzles 54 joins the air impelled through an annular passage 51. A fairing 18, forming the chamber 21 and supporting the nozzle structure, and a fairing 26 housing the shaft bearings are supported within the fan casing 11 by struts 22, 27 respectively. A shroud 73 is secured, as by brazing, to the nozzle blades 66. A labyrinth seal 75 is provided. The fan blades 50 may be formed separately from the wheel 41 and secured in place. The diffuser blades 60 are formed on a diffuser 55 which is bolted to the wheel 41. Alternatively. the diffuser 55 may be formed integrally with the wheel 41 or the diffuser blades 60 may be formed on the radially extending surface 63 of the wheel. The diffuser blades may be of sheet metal.
