Abstract: The fuel spray device is adapted for use in the thrust augmentor or afterburner of a gas turbine engine. The fuel spray device includes a fuel spray manifold having a plurality of spaced apart ejection orifices and a plurality of nozzle pintles each having a decreasing cross-sectional portion, such as a conical portion, against which the orifice wall seats when there is no fuel pressure and relative to which the orifice wall moves as fuel pressure increases to increase fuel flow rate and each pintle having a substantially constant cross-sectional portion, such as a cylindrical portion, downstream of the conical portion to accommodate movement of the orifice wall of the manifold with a minimal effect on fuel flow rate through the orifice.

Abstract: A power recovery expander for use with a motive fluid of hot gas with entrained particulates is disclosed. Means for removal of entrained particulates and for cooling portions of the turbomachine are provided. Additionally, cooling fluid is directed to a separate cooling chamber, said cooling fluid being used to draw additional particulate matters from the motive fluid.

Abstract: A turbocharger of the present invention is provided with a thermo-reducing means between the turbine housing and the bearing housing in order to reduce the heat transferred from the turbine housing to the bearing housing. The thermo-reducing means comprises a thermo-isolating means such as an annular member made of a low heat conductive material. Also, the annular member contacts with the wall of the turbine housing which has a high thermal resistance, so that the heat transferred from the turbine housing to the connecting portion is reduced. The thermo-reducing means also comprises a sensible heat reducing means which is composed of a layer made of a low conductive material, on the inner surface of the wall of the turbine housing, preventing the heat transferred from the exhaust gas to the wall, and a layer made of a high emissive material, on the outer surface of the wall of the turbine housing radiating out the heat effectively.

Abstract: Means are provided for controlling and modulating the temperature of the hot gas exiting the combustor associated with a gas turbine engine. The means establish a preselected temperature gradient in the hot gas so as to provide a flow of hot gas at a relatively higher temperature through gaps between adjacent turbine vanes and a flow of hot gas at a relatively lower temperature upon the vanes.

Abstract: A system for the collection and storage of energy, wherein compressed air from any source is utilized to make a fully automatic, sequential series of chamber-to-chamber blow-type vertical water lifts to an elevated water storage reservoir. Potential energy stored in the reservoir is extracted by means of an hydraulic air compressor located below the reservoir and functioning by virtue of the resultant pressure head.
