The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...
On the other end a transformer enables the generator to work more efficiently into the electrical load. An explosively pumped flux compression generator (EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive. EPFCGs are physically destroyed during operation, making them single-use.
The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage.

They comprise a compressor, combustor, impeller/turbine and electric generator on a single shaft or two. They can have a recuperator capturing waste heat to improve the compressor efficiency, an intercooler and reheat. They rotate at over 40,000 RPM and a common single shaft microturbine rotate usually at 90,000 to 120,000 RPM. [2]
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
Kirloskar Brothers Limited Kirloskarvadi; Kirloskar Brothers Limited Kirloskarvadi-Palus, SPP Pumps (UK), Braybar Pumps Ltd., (South Africa) and Kolhapur Steels Ltd. [3] [4] Kirloskar Brothers produces Centrifugal pumps from 0.1 kW to 26 mega-watts single pumps, pumping liquids in excess of 35,000 liters/sec thus producing some of the largest pumps by size and horsepower.
