Combined electric applications in transport [PDF]

, 2008
Maximizing the efficiency in transport vehicles will be a necessity. This may be realized by introducing a power electronic conversion between the Internal Combustion Engine (ICE) and the wheels. Hence the ICE may be used at its maximal efficiency point.

An Experimental Investigation of Low-Frequency Active Excitation in Scramjet Combustor Using a Micro-Pulse Detonation Engine

Aerospace
A micro-pulse detonation engine (μPDE) was designed and installed to a direct-connect scramjet combustor of Pusan National University (PNU-DCSC). The active excitation on the scramjet combustor was experimentally studied using the μPDE operating at ...
