Siemens-Schuckert D.III

The revolutionary Siemens-Halske engine was the foundation of the Siemens-Schuckert D.III fighter, but the engine proved troublesome and the type was frequently grounded. The engine was an eleven-cylinder engine with the crankshaft rotating in one direction at 900rpm and the crankcase and cylinder rotating in the other at 900rpm, which was supposed to reduce the gyroscopic forces and allow the propeller to run at a lower, more efficient speed. All good in theory. Then engine ran hot (since it was rotating at half speed compared to a conventional rotary) and frequently seized due to poor-quality lubricant.

When its engine was working, the D.III had outstanding climbing characteristics and it was quite nimble.
