US Patent:

51276062, Jul 7, 1992

Filed:

Nov 16, 1990

Appl. No.:

7/614884

Inventors:

Chi F. Chan - Mesa AZ
John E. Hill - Phoenix AZ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

B64D 2700

US Classification:

244 54

Abstract:

An aircraft engine mount adapter and method is provided that permits the coupling of an aircraft engine to an aircraft when the pickup points on the engine are incompatible with the location of the mounting pins on the aircraft. The adapter consists of an arcuate shaped member having sufficient lateral curvature so as to be selectively positionable along the length and about the circumference of the engine's casing. Means for locking onto the mounting pins are disposed along the outer surface of the member. The member has a plurality of flanges which are bolted to flanges extending outwards from the engine's casing.

Assignee:

AlliedSignal Inc. - Morris Township NJ

International Classification:

F04D 2944

US Classification:

415206

Abstract:

To contain high energy fragments generated by a hub burst, a compressor containment assembly in a gas turbine engine includes a diffuser housing having an arcuate portion that defines a channel which traps the high energy fragments and an axial facing U-shaped which imparts flexibility. The assembly also includes a concave back shroud having a series of grooves that create resistance for the fragments as they slide along its surface. At its radial outer end the back shroud has an annular rim that absorbs some of the energy and delays the shearing of bolts. A bumper is disposed between the back shroud and a turbine wheel to limit the deflection of the back shroud during a hub burst.
