US Classification:
416244R
Abstract:
A rotor assembly for a miniature gas turbine propulsion system comprises a centrifugal compressor wheel, a turbine wheel, a shaft and a tie bolt. The centrifugal compressor wheel includes a first curved tooth coupling, and the turbine wheel includes a second curved tooth coupling interconnected with the first curved tooth coupling. The shaft extends from the centrifugal compressor wheel, and the tie bolt extends between the shaft and the turbine wheel to bring the first curved tooth coupling into compression with the second curved tooth coupling. As such, the compressor wheel and the turbine wheel are assembled and remain, over the operational envelope of the propulsion system, in a reliably robust aligned configuration.
Torque Meter

46906142, Sep 1, 1987
Filed:
Nov 4, 1985
Appl. No.:
6/794651
Inventors:
Reginald G. Keetley - Daphne AL
Keith Allen - Hollingworth Via Hyde, GB2
Keith Allen - Hollingworth Via Hyde, GB2
Assignee:
Teledyne Industries, Inc. - Los Angeles CA
International Classification:
B64C 1138
US Classification:
416 43
Abstract:
A torque meter is provided for use in conjunction with a layshaft having a forward and rear end and which is rotatably mounted in a housing. The layshaft is axially movable with respect to the housing between a forward and a retracted position while a gearing arrangement in mesh with the layshaft urges the layshaft towards its forward position with a force proportional to the shaft torque. The torque meter comprises a body secured to the housing adjacent the front end of the layshaft which forms a chamber open to the front end of the layshaft while a piston is axially slidably mounted within the chamber. The chamber is pressurized with a fluid, such as oil, which urges the piston against the front end of the layshaft with a force proportional to the pressure so that the piston balances the layshaft against the axial force imposed by the engine. A fluid pressure gauge determines the pressure within the chamber which varies proportionately with the layshaft torque. In addition, a piston ring on the piston opens the fluid chamber to an opening in the body and a passageway in the housing when the layshaft moves to its rearward position, indicative of a negative shaft torque condition, whereupon fluid discharges from the chamber, through the passageway, and activates a control assembly.

48541265, Aug 8, 1989
Filed:
Oct 29, 1987
Appl. No.:
7/115599
Inventors:
Robert W. Chevis - Conventry, GB2
Reginald G. Keetley - Daphne AL
Reginald G. Keetley - Daphne AL
Assignee:
Teledyne Industries, Inc. - Los Angeles CA
International Classification:
F02C 100
US Classification:
60726
Abstract:
A one-piece housing casting comprising a hub adapted to receive a turbine shaft therethrough and a radially extending flange on the outer periphery of the hub. The flange includes radially aligned annular surface portion and means for spacing the surface a predetermined distance from a radially aligned housing wall close to the outlet of the centrifugal compressor. The flange also includes an axially extended portion having an axially extended surface and means for spacing the surface away from an axially extending surface on a turbine housing wall to define a passage therebetween. Preferably, the means for spacing the walls apart from the turbine housing wall surfaces comprise diffuser vanes integrally formed on the radially and axially aligned surfaces of the flange of the diffuser member.
