Intake Compressin Power Exhaust <more>

The DBR mechanically is designed with a rotating disc (hence the moniker) that is sandwiched between plates that contain a series of small chambers that might best be described as divots.  The rotating disc itself carries spinning drive plates, that each contain a lobe, the individual lobes in turn engaging each of the chambers or divots sequentially.  With each sweep of a lobe through a chamber a complete exchange of gases occurs.

With each sweep through an individual chamber, two cycles effectively and efficiently are completed.  Specifically, air is drawn in behind one sweeping drive plate while exhaust gases are pushed out in front of it. The four Brayton cycles (as in a turbine), are positively displaced and separately processed for optimization. The aerodynamic penalty at partial power with turbines is eliminated.

This operation and functionality gives the DBRE remarkable power density potential.  A 525 cu in, 400hp engine would be about the size of an economy car’s spare tire
