<h1>Engine Test Bench</h1>

<br>
It is the big aim of Lothar to reach a stage enabling him to design and
build a high speed internal combustion engine which will join the worlds top
control line combat engines. Lothar think that he has to employ advanced simulation
methods concerning fluid dynamics, thermodynamics and and stress. In tandem
with an engine test bench to get the input data for the simulation models
as well as to verify the simulation results, Lothar try to reach this aim.<br>
The picture below shows Lothars actual engine test bench. <br>

This engine test bench employs the motor of a 750 Watt vacuum cleaner
as a starter and brake-dynamometer. Engines could be driven in the motored
condition with speeds up to 20000/min. In case the vacuum cleaner motor acts
as a brake-dynamometer, the current of the stator electromagnets is adjusted
to get the required brake torque. The electrical power which is induced in
the rotor is extracted from the system using a resistor array, whereas the
current serves as a torque-monitor after calibration.<br>
