Abstract: An air-inlet duct includes an outer wall, an inner wall, and a splitter. The splitter cooperates with the outer wall to establish a particle separator which separates particles entrained in an inlet flow moving through the air-inlet duct to provide a clean flow of air to a compressor section of a gas turbine engine.

Abstract: An adaptive inertial particle separation system may include an active configuration and a passive configuration. The system may comprise an air-intake duct including an outer wall spaced apart from a central axis, an inner wall located between the outer wall and the engine rotation axis, an intake passage defined in part by the inner wall and the outer wall, and a splitter located between the outer wall and the inner wall. The system may further include a sensor operatively connected to the air-intake duct and operative to initiate at least one of the active configuration and passive configuration.

Abstract: An enhanced pressure-wave supercharger for a combustion engine utilizes a superior pressure wave process cycle design. The design utilizes a select final portion of the compressed gas stream exiting the rotor, and supplies it to a subsequent inlet port ahead of and prior to the introduction into the rotor of the aspirated air to be compressed. Work is extracted within the rotor from this gas stream and transferred into rotational energy of the rotor through using a portion the available momentum of the compressed gas via incidence on the rotor webs to turn the rotor by means of conventional turbomachinery principles.
