US Patent:

42905583, Sep 22, 1981

Filed:

Sep 18, 1979

Appl. No.:

6/076638

Inventors:

Robert E. Coburn - Mansfield Center CT
Ronald M. Gabriel - Glastonbury CT
Richard S. Tuthill - Bolton CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

B05B 710

US Classification:

239400

Abstract:

An annulus formed in the nut of a fuel nozzle to collect, distribute and atomize water droplets fed into the fuel nozzle for increased thrust produced by a turbine type power plant powering aircraft is discretely formed adjacent the discharge juncture point and discharged angularly into and with respect to the fuel spray emitted into the combustion zone for smoke reduction purposes.

Filed:

Mar 3, 1986

Appl. No.:

6/835136

Inventors:

Robert E. Coburn - Mansfield Center CT
John A. Matthews - Melrose CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02C 306
F02C 720
F02C 100

US Classification:

60 3936

Abstract:

A sealing device which is adapted to cooperate with and be secured to the outwardly extending tabs on the inlet vanes for the turbine in which the tabs provide a forwardly facing surface and the sealing device has a rearwardly facing surface in contact with one another and with the parts secured together by a row of bolts in which the sealing element has a flange along the outer edge of the element between certain bolts to reinforce the plate and between other bolts the sealing element is reinforced by plates extending between adjacent bolts and secured to the forward side of the sealing element by said bolts.

International Classification:

F02C 720

US Classification:

60 3932

Abstract:

A sliding expansion joint (68) for the interface between an annular combustor head (24) and a downstream-extending liner (47) of a combustion chamber (18) includes an inward facing cylindrical surface (78) on the head (24) and a thickened upstream ring (74) in the liner (47). A cooled, radially extending bulkhead (36) isolates the joint (68) thermally from the high temperature combustion reaction (50). A region of reduced static air pressure is induced adjacent the joint (68) by the flow of air (86) over the convex combustor dome (30). Any air leakage through joint (68) adds to the existing flow of cooling air (106) adjacent the liner (47).
