Publication number: 20140099190Abstract: A turbine housing (430) includes a support housing (440) with an annular shape. The support housing (432) includes an outer surface (433) and an inner surface (434). The inner surface (434) is located radially inward from the outer surface (433). A plurality of cooling holes (431) extols through the support housing(440) from the outer surface (433) to the inner surface (434). The cooling holes (431) include a stadium shape. The stadium shape includes a rectangle with a top and bottom of a first length and ends capped with semicircles with a radius of a second length. The cooling holes (431) are disposed at an angle (98) from thirty to sixty degrees. The angle (98) is between a line (96) projected to the outer surface (433) from an axis of the turbine housing (430) and a line (97) extending through a center of each cooling hole (431) parallel to the first length.Type: ApplicationFiled: October 5, 2012Publication date: April 10, 2014Applicant: SOLAR TURBINES INCORPORATEDInventors: Christopher J.

Patent number: 5603606Abstract: Cooling air delivery systems for gas turbine engines are used to increase component life and increase power and efficiencies. The present system increases the component life and increases efficiencies by better utilizing the cooling air bled from the compressor section of the gas turbine engine. For example, a flow of cooling air is directed to a plurality of airfoils having a leading edge and includes a cooling path therein each of the plurality of blades in which is positioned a device which causes the cooling air to swirl and more effectively absorb heat and cool the leading edge of the airfoil.Type: GrantFiled: November 14, 1994Date of Patent: February 18, 1997Assignee: Solar Turbines IncorporatedInventors: Boris Glezer, Tsuhon Lin, Moon Hee-Koo
