US Patent:

45121583, Apr 23, 1985

Filed:

Jun 16, 1983

Appl. No.:

6/504995

Inventors:

Edmund E. Striebel - South Windsor CT
John A. Matthews - Melrose CT
Domingo Sepulveda - Vernon CT
Francis C. Pane - South Windsor CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02C 720

US Classification:

60740

Abstract:

This invention minimizes wakes manifested by a fuel nozzle support structure extending through an annular diffuser engine to the burner in a gas turbine engine, spaced walls extending from the inner and outer wall of the diffuser project toward the nozzle support downstream of the support that passes transverse to the flow, one wall being shaped conically and the other being shaped bell-mouthed and convergent.

Vito J. Sarli - Manchester CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F23R 310
F02C 718

US Classification:

60 3932

Abstract:

This invention relates to the construction of the fuel nozzle guide of a turbine power plant and provides sealing while allowing relative movement between the fuel nozzle and combustion liner, and includes the judicious location of cooling passages that permit constant cooling and purging for preventing local hot spots resulting from unwanted flame holding. CROSS REFERENCE This invention is related to the invention disclosed in copending patent application entitled FUEL NOZZLE GUIDE HEAT SHIELD FOR A GAS TURBINE ENGINE, filed by S. C. Peterson, L. W. Stevens and I. S. Tanrikut on even date and assigned to the same assignee of this application.

Appl. No.:

7/068870

John A. Matthews - Melrose CT
Melvin H. Zeisser - Marlborough CT
Robert E. Coburn - Mansfield Center CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02C 100

US Classification:

60757

Abstract:

A seal assembly secured to the downstream end of a gas turbine engine combustor liner forms a gas path seal at the upstream facing platforms of turbine inlet guide vanes and also cools the vane platforms. The seal assembly includes an annular coolant compartment which feeds cooling air to a plurality of circumferentially spaced apart, axially extending open-ended channels formed between a conical portion of the downstream-most combustor liner and an annular baffle member disposed on the non-gas path side of the conical liner. The seal assembly is supported and axially located on a cylindrical surface which permits locating the seal assembly such that the downstream end of the conical liner is closely spaced from the turbine inlet guide vane platforms to reduce leakage from the gas path. The open-ended channels are also closely spaced from the vane platforms and located to direct high velocity coolant fluid against the upstream facing surfaces of the platforms at circumferential locations where the pressure in the gas path is highest, thereby further reducing leakage from the gas path.

International Classification:

G21C 1102

US Classification:

376287

Abstract:

A radiation-reducing door assembly which may be configured as either an entry port or a ventilation port. The door assembly includes a split ring flange-type mounting bracket which can be quickly and easily installed on a manway flange regardless of the state of the manway cover mounting studs. A pair of radiation shielding doors or a ventilation port door may be quickly and easily coupled to the split ring mounting bracket.

International Classification:

B05B 1500

US Classification:

2393975

Abstract:

A fuel nozzle for a gas turbine engine is constructed with two major castings where one is the support and the other is the head, both welded together adjacent the fuel orifice plate. The fuel passage is cast into the support providing a smooth radius from the radial to axial flow path and a smooth transition from the circular to the annular cross section. This configuration allows dimension control over the filming lip and other critical dimensions of the nozzle.
