NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...

The Midnight Hawk features a single main rotor, a single-seat open cockpit with a windshield, tricycle landing gear with wheel pants and a four-cylinder, air-cooled, four-stroke, 90 hp (67 kW) Subaru EA-82 automotive conversion engine in pusher configuration. The engine is available with a belt reduction drive or as a direct drive version. [1] [2]
According to the Sagnac effect, rotation induces a small difference between the time it takes light to traverse the ring in the two directions.This introduces a tiny separation between the frequencies of the counter-propagating beams, a motion of the standing wave pattern within the ring, and thus a beat pattern when those two beams interfere outside the ring.
The Microsoft SideWinder Force Feedback Wheel is a steering wheel controller for sim racing. It was the first wheel controller to contain force feedback. [ 14 ] The USB version of the wheel is compatible with one PlayStation 2 game, Tokyo Xtreme Racer Zero .
Inside the tire was a 25.5-inch-diameter (65 cm) titanium bump stop frame to protect the hub. Dust guards were mounted above the wheels. Each wheel had its own electric drive made by Delco, a brushed DC electric motor capable of 0.25 horsepower (190 W) at 10,000 rpm, attached to the wheel via an 80:1 harmonic drive, and a mechanical brake unit ...
The XOZ-1 naval autogyro, as a landplane The XOZ-1 naval autogyro, as a floatplane. In 1935 Pennsylvania Aircraft produced a two-seat trainer version of the Gyroplane, generally known by its US Navy name Pennsylvania XOZ-1.
Three types of electric road systems. An electric bus (black) receives power from the road: (A) with three inductive pickups (red) from a strip of resonant inductive coils (blue) embedded several centimeters under the road (gray); (B) with a current collector (red) sliding over a ground-level power supply rail segment (blue) flush with the surface of the road (gray); (C) with an overhead ...
