Its advantage is its compact design, low weight with a thrust of up to 1,300 N, and low fuel consumption in the given power category. The generator output is 750 W. One of the PBS TJ100 engine versions enables landing on water. The PBS TJ100 engine is a single-shaft jet engine consisting of a radial compressor, radial and axial diffuser, annular combustion chamber, axial turbine and a fixed outlet nozzle. The PBS TJ100 jet engine was developed for UAVs, missiles, light sport aircraft and gliders with an additional engine. We have delivered hundreds of our jet engines for manned experimental aircrafts and unmanned aircrafts all around the world.

Primary objective in wind turbine design is to maximize the aerodynamic efficiency, or power extracted from the wind. But this objective should be met by well satisfying mechanical strength criteria and economical aspects. In this video we will see impact of number of blades, blade shape, blade length and tower height on wind turbine design. The next big factor which is affecting performance of wind turbine is shape and orientation of blade cross section. A moving machine experiences fluid flow at a different velocity than the actual velocity. It is called as relative or apparent velocity. Apparent velocity of flow is difference between actual flow and blade velocity. Absolute velocity of the flow is shown in first figure, while apparent velocity in the second figure. It is clear that apparent velocity of flow is vectorial difference between actual and blade velocity. The vector difference is shown in the first figure at a particular cross section. A rotating blade will experience an apparent velocity of flow.

Are you looking to build a wind turbine, or to buy a windmill, and you want to know whether it is better to get yourself a vertical axis wind turbine or a conventional horizontal windmill? It is a good idea to educate yourself on the differences between vertical and horizontal axis wind turbines. Obviously, you want to get the one that has the best return on investment, whether you will buy a wind turbine or build it yourself.

A variable speed wind turbine is disclosed comprising a turbine rotor that drives an AC induction generator, a power converter that converts the generator output to fixed-frequency AC power, a generator controller, and an inverter controller. The generator controller uses field orientation to regulate either stator currents or voltages to control the torque reacted by the generator. The inverter controller regulates the output currents to supply multi-phase AC power having leading or lagging currents at an angle specified by a power factor control signal.

The NASA Glenn Research Center serves as NASA's lead center for aeropropuision. Several programs are underway to explore revolutiolutionary airbreathing propulsion systems in response to the challenge of reducing the cost of space transportation. Concepts being investigated include rocket-based combined cycle (RBCC), pulse detonation wave, and turbine-based combined cycle (TBCC) engines.

The SR-71 Blackbird is powered by two Pratt & Whitney J-58 turbo-ramjets, each developing 32,500 pounds of thrust with afterburning. The critical problems concerning supersonic flight with air breathing engines are concentrated in the air inlet area. The circular air intakes of the SR-71 contain a center body tipped with a conical spike. The spike is movable, forward for takeoff and climb to 30,000 feet after which, as speed builds up, it moves rearward, controlling the amount of air entering the engine. As it does so, Air Inlet Bypass Doors in the side of the nacelle close to establish the correct flow of air through the engine, holding the supersonic shock wave in it's critical position within the inlet. The engine itself operates at subsonic speed.

This book provides a practical guide to the fundamentals of performance, including the requirements of all major applications: power generation, mechanical drive, automotive, marine and aircraft installations. The new edition includes two additional chapters on performance issues of engines in-service and on the techno-economic issues that determine whether a gas turbine project will be profitable.
