A secondary airflow path can be provided for a compressor of a compressor system. The secondary airflow path can provide pressurized air to a boost port in communication with a closed compression cell of the compressor.

A system for cooling a superconducting motor includes a combustor and fuel tank that contains a fuel. The system further includes a cooling system that provides the fuel to the superconducting motor or a cryocooler to cool the superconducting motor, resulting in at least partially vaporized fuel coming out of the superconducting motor or cryocooler. The cooling system also a cryocooler and a two-phase ejector that mixes the fuel from the tank and the at least partially vaporized fuel to produce a mixed fuel. The combustor receives the mixed fuel and generates electric power due its combustion. The power can be provided to the superconducting motor.

A system of an air-augmented gas turbine engine is provided comprising a gas turbine engine drawing air into an increasingly narrow and elongated compression chamber, the action compressing drawn-in air. The system also forces the compressed air into and through a narrowed section of the compression chamber before the air reaching a combustion chamber, the section running alongside a lengthwise exterior surface of the combustion chamber, positioning of the section causing the compressed air to receive increased heating based on proximity of the section to the combustion chamber. The system ignites in the compression chamber a mixture of the heated compressed air and injected fuel, causing increase in temperature and velocity of the mixture. The system also directs the superheated mixture from the combustion chamber through a combustion nozzle and into an entrained state with a larger volume of cooler air, resulting in increased power and efficiency of the engine.

An energy generating system (10) includes: (i) a first conduit (14) for conveying air there along, which first conduit defines: a first conduit inlet for receiving air; and a first conduit outlet (14a) for discharging air; (ii) a turbine rotor (22); (iii) a turbine housing (20) radially surrounding the turbine rotor; and (iv) an exhaust conduit (18) that extends from the turbine housing to convey air discharged from the turbine rotor. The turbine housing and first conduit define an annular gap (24) therebetween; and the turbine rotor is: (a) disposed within the annular gap defined between the turbine housing and the first conduit; and (b) rotatably secured to the first conduit.

A gas turbine system, comprising a combustor apparatus, which includes at least one combustion chamber configured to: receive compressed gas and a combustion fuel, generate combustion of the compressed gas thereby generating combusted gas; and to release the combusted gas toward a turbine for rotating the turbine. The at least one combustion chamber is configured to have a plurality of discrete sequential combustion cycles, each combustion cycle having an initial time interval in which the compressed gas and the combustion fuel are received, and a final time interval in which the combustion is performed and the combusted gas is released toward the turbine, the initial and final time interval being sequential to one another.
