Abstract: A combustor for use in a gas turbine engine is provided with a first wall defining a combustion zone; an outer casing partially defining a cooling plenum about the first wall; a second wall spaced apart from the first wall and defining together therewith a second plenum, the second wall bearing a plurality of perforations for passing fluid from the first plenum in impinging streams upon the first wall; and a plurality of ribs extending between the first and second walls and compartmentalizing the second plenum. The ribs add substantial stiffness to the combustor as well as providing for independently controlled cooling of the substantially isolated compartments formed thereby. The impinging streams provided by the perforations in the second wall substantially increase local fluid velocities and conductive heat transfer.

Abstract: A fluid pumping and energy recovery device may include a housing that defines an impeller chamber and a motor/generator chamber. An impeller may reside within the impeller chamber; and a motor/generator may reside in the motor/generator chamber. The motor/generator may include a stator and a rotor. The rotor may be coupled to the impeller and supported (e.g., by magnetic bearings) to rotate in the stator. The rotor may generate electrical power in a generating mode and rotate in response to electrical power applied to the stator in a motoring mode. Seals may be adapted to hydraulically isolate the pump chamber from the motor/generator chamber by sealing against a rotating surface of the device. In certain instances, sealing is achieved using a bidirectional seal.
