US Patent:

52243419, Jul 6, 1993

Filed:

Jan 6, 1992

Appl. No.:

7/817195

Inventors:

Alan D. Munroe - Glastonbury CT
Karl D. Blume - Rocky Hill CT
Robert E. Gurney - Hampden MA

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02C 720
F02K 302

US Classification:

602261

Abstract:

A method and apparatus which facilitate separation of a gas turbofan powerplant into modules for shipping, maintenance and repair is disclosed. Various construction details are developed which provide means for mounting a fan cowling to an engine core in a manner which permits transference of operational loads from the fan cowling to the engine core and separation of the fan cowling from the engine core. In one embodiment, a fan cowling (46) is attached to an engine core (18) by a plurality of radially extending through struts (64). The through struts include a bolted joint (72) which permits separation of a powerplant (12) into a first module and a second module. For this embodiment, a method for varying between an assembled and disassembled condition is comprised of manipulating the joints between an engaged and disengaged position and axially moving the separate modules along a longitudinal centerline (14).

Abstract:

A linkage system for the variable stator vanes of a gas turbine engine is augmented by control means operable as a function of compressor speed designed to match the aerodynamic requirements of the airflow through the compressor so as to define the rate of schedule change of the vanes over its angular movement by compensating for the inadequacies inherent in the capabilities of the linkage system.
