The efficiency of helicopters is limited due to the high power losses of combustion engines, a fraction of which can be recovered and provided to the electrical bus by exploiting the heat found in the exhaust gases and through power electronics converters. The first system recovers energy through a thermoelectric generator, whereas the second through a permanent magnet generator rotated by a steam...
Mechanical load simulators are useful in various cases, where we wish to test an electromechanical system. A mechanical load simulator can be used to emulate a wide variety of loads, such as industrial loads, electric vehicle drivetrain, etc. In this paper, a load simulator build for the testing of various electromotion systems, with the capability of four quadrant operation (positive or negative...
Research in modern helicopters is targeted into the increase of their efficiency due to economical and ecological pressures. This paper introduces two innovative methods of absorbing a ratio of the energy remains of the main engine exhaust gases and converting it to electrical energy. The recovered power is then injected to the electrical bus of the helicopter through power electronics converters...
