A wind-tunnel type power generator includes an outer cover, a turbine rotor, an air escape valve, and at least a rear fin. The outer cover is a convergent-divergent shape and the turbine rotor is installed into an inner flowing path thereof, the air escape valve is installed on the outer cover and the rear fin is installed on the surface of the outer cover. The acceleration of the outer cover, the higher efficiency of the turbine rotor, and the reducing pressure of the air escape valve is to gain the wider operation area, smaller space, lower weight, lower noise, and higher efficiency of the wind-tunnel type power generator.

A recuperated gas turbine engine. The gas turbine engine includes a heat exchanger, and gas turbine (including compressor, can-type combustor and turbine). The heat exchanger includes a compressed air passageway and a turbine exhaust gas passageway adjacent to each other within the casing which extend spirally throughout the heat exchanger and towards an inner cylindrical chamber in which the combustor is positioned approximately to the center of the casing. Improved engine fuel efficiency is achieved by preheating the compressed air before it reaches the combustor with the higher-temperature exhaust gas. A can-type combustor is used for alleviating heat-dissipation issues to improve efficiency of the combustion. A concentric back-to-back rotor arrangement significantly shortens the length of a conventional engine turbine rotor which improves on the operational stability of a gas turbine engine.

Gas turbine engine

An engine core structure for a gas turbine engine includes an outer annular shaft body, a turbine rotor body, turbine rotor blades radially connected between the outer annular shaft body and the turbine rotor body to hold the turbine rotor body in the rear section of the outer annular shaft body, the outer annular shaft body including slots through which compressed air passes in a radially inward direction, and a can type combustor mounted in a receiving clamber inside the outer annular shaft body to enlarge the diameter of the core shaft, to avoid vibration due to resonance, to save space, to eliminate dissipation of heat, and to improve the thermal efficiency of the gas turbine engine.

A front plunger pressure-swirl atomizer is disclosed, which is applied to a fuel atomizer of a micro gas turbine engine and includes a nozzle cap, a central plunger swirler, a central plunger fastening barrel. The front plunger pressure-swirl atomizer is installed at the seat of an engine. The present invention has the advantages of occupying a smaller space, only needing a small operating pressure, a simple flow channel structure, and fewer components, being easily assembled and a superior atomizing property. Therefore, the defects, such as complex finishing process of flow channel and difficult to be assembled, in the prior art are improved effectively.
