A thermal abatement system comprises an axial inlet, radial outlet supercharger. A main case comprises at least two rotor bores, an inlet plane and an outlet plane. The inlet plane is perpendicular to the outlet plane. An inlet wall comprises an inner surface. Two rotor mounting recesses are in the inner surface, and the inlet wall is parallel to the inlet plane. An outlet is in the outlet plane. An inlet is in the inlet plane. At least two rotors are configured to move air from the inlet to the outlet. The main case comprises at least two backflow ports. An intercooler is connected to receive air expelled from the supercharger, to cool the received air, and to expel the cooled air to the at least two back flow ports.

Thermal abatement systems

A supercharger outlet resonator comprises a housing, a first surface comprising a first opening and a housing axis bisecting the first opening, and a second surface comprising a second opening, the second surface located parallel to the first surface. A channel is perpendicular to the housing axis and connects the first opening to the second opening. The channel comprises at least one sidewall. An envelope is fluidly separated from the channel by the at least one sidewall, the envelope at least partially surrounds the channel, and the envelope extends from the first surface to the second surface. The envelope comprises a third opening and at least one second sidewall. A noise-reducing material located on the housing.

A leak detection system for a high-temperature aerospace fluid duct may include a rigid metal fluid duct, an electrically conductive polymer disposed around the high-temperature fluid duct, the conductive polymer configured to melt in response to a leak of high-temperature fluid from the high-temperature fluid duct. The system may include a sensor configured to monitor at least one electrical characteristic of the electrically conductive polymer. The system may include a layer of insulation disposed between the electrically conductive polymer and the high-temperature fluid duct.

A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the 'pressure cell') partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.
