摘要： The invention provides a micro-gas turbine engine and associated microcomponentry. The engine components, including, e.g., a compressor, a diffuser having diffuser vanes, a combustion chamber, turbine guide vanes, and a turbine are each manufactured by, e.g., microfabrication techniques, of a structural material common to all of the elements, e.g., a microelectronic material such as silicon or silicon carbide. Vapor deposition techniques, as well as bulk wafer etching techniques, can be employed to produce the engine. The engine includes a rotor having a shaft with a substantially untapered compressor disk on a first end, defining a centrifugal compressor, and a substantially untapered turbine disk on the opposite end, defining a radial inflow turbine. The rotor is preferably formed of a material characterized by a strength-to-density ratio that enables a rotor speed of at least about 500,000 rotations per minute. An annular, axial-flow combustion chamber is provided that is located axially between the compressor and turbine disks and that has a ratio of annular height to axial length of at least about 0.5. The micro-gas turbine engine can be configured with an integral microgenerator as a source of electrical power, and can be employed for a wide range of power, propulsion, and thermodynamic cycle applications.

摘要： The invention overcomes limitations of conventional power and thermodynamic sources by with micromachinery components that enable production of significant power and efficient operation of thermodynamic systems in the millimeter and micron regime to meet the efficiency, mobility, modularity, weight, and cost requirements of many modern applications. A micromachine of the invention has a rotor disk journalled for rotation in a stationary structure by a journal bearing. A plurality of radial flow rotor blades, substantially untapered in height, are disposed on a first rotor disk face, and an electrically conducting region is disposed on a rotor disk face. A plurality of stator electrodes that are electrically interconnected to define multiple electrical stator phases are disposed on a wall of the stationary structure located opposite the electrically conducting region of the rotor disk. A first orifice in the stationary structure provides fluidic communication with the first rotor disk face at a location radially central of the rotor blades, and a second orifice in the stationary structure provides fluidic communication with the first rotor disk face at a location radially peripheral of the rotor blades. An electrical connection to the stator electrode configuration is provided for stator electrode excitation and for power transfer with the stator electrode configuration as the rotor disk rotates.

摘要： Double-sided, high-frequency response heat flux gauge for use on metal tune blading consists of a metal film (1500A) resistance thermometer sputtered on both sides of a thin (25 .mu.m) polyimide sheet. The temperature difference across the polyimide is a direct measure of the heat flux at low frequencies, while a quasi-one-dimensional analysis is used to infer the high-frequency heat flux from the upper surface history. A new method of calibrating the heat flux gauge utilizes light source applied to a plurality of fluids covering the surface of the gauge, measuring the temporal output of the gauge and utilizing derived calibration formula.

摘要： A compressor or pump is connected to a discharge plenum. The plenum includes a movable wall whose motion varies the volume of the plenum. The wall is connected to passive elements forming a spring-mass-damper system whose characteristics are selected to damp pressure fluctuations in the plenum which would give rise to pumping system instabilities. In another aspect of the invention, a compressor is connected to a discharge plenum which in turn is connected to an exit throttle. The throttle includes a movable portion whose motion varies the throttle area. The movable portion is connected to passive elements forming a spring-mass-damper system selected to damp pressure fluctuations in the plenum. In another embodiment, the plenum communicates with a fixed area throttle and a variable area throttle. The variable area throttle includes a movable portion connected to passive elements selected to damp pressure fluctuations in the plenum. Aerodynamic surge control is effected by coupling a second Helmholtz resonator to the plenum.
