Abstract: A construction of a gas turbine combustion chamber which facilitates relighting the fuel immediately after flame-out. The construction comprises a catalytic coating on the combustor wall, preferably with areas left uncoated to allow the flame to propagate away from the combustor wall and into the bulk gas flow.

Abstract: The disclosure relates to a ring type seal with positive self centering anti-rotation characteristics intended to enhance seal life and reliability by elimination of lateral displacement forces arising from conventional anti-rotational features which may cause uneven or excessive seal wear. The invention disclosed is particularly suited to segmented ring seal constructions.

Abstract: A turbine wheel made up of a hub having carbon cloth discs impregnated with a carbon bearing resin, integral blades formed of chopped carbon fibers impregnated with the resin, and continuous carbon strengthening fibers in the hub and blades which extend circumferentially around the hub and radially through the blades to provide maximum strength. The method of manufacture comprises providing a fixture having slotted tip and root section template rings and aft and forward plates, alternately laying cloth discs within the inner ring and threading carbon fibers in and then out of the templates, adding chopped carbon fibers between the templates, impregnating the material with a carbon bearing resin, densifying the wheel by chemical vapor deposition, and machining the blades around the radial portions of the threaded carbon fibers.

Abstract: Methanol is delivered by a fuel pump to a reformer at a relatively high pressure, where it is heated by exhaust gases from a spark ignition engine and decomposed over a catalyst bed to form carbon dioxide and hydrogen, this being a constant pressure process. The mixture is fed to an auxiliary turbine which helps drive the output shaft of the spark ignition engine. The low pressure exhaust gases from the auxiliary turbine are mixed with air and fed to a spark ignition engine where they are combusted.

Abstract: An engine speed governor which utilizes the fuel mass itself as a control element, combined with fuel pressure regulation and orifice pressure drop. The fuel is fed through an orifice and then inwardly through radial slots in a shaft rotating at a speed proportional to engine speed, the rotating columns of fuel in these slots being subjected to centrifugal force and opposing external supply pressure. Equilibrium is achieved when the inlet pressure equals the sum of orifice and slot pressure drops. In the illustrated embodiment, fuel pressure is supplied by pressurizing a fuel tank with compressor discharge air, and thus pressurizing fuel in a manner compensating for slightly lower governed speed when fuel demands are higher. The illustrated embodiment also includes multiple speed selection achieved by selectively opening a plurality of bleed orifices leading from the compressor line to the fuel tank.
