Editing Rotary engine (section)

==Other rotary engines==
Besides the configuration of cylinders moving around a fixed crankshaft, several different engine designs are also called ''rotary engines''. The most notable [[pistonless rotary engine]], the [[Wankel engine|Wankel rotary engine]] has been used by [[NSU Motorenwerke AG|NSU]] in the [[NSU Ro 80|Ro80]] car, by [[Mazda]] in a variety of cars such as the RX-series, and in some aviation applications.

In the late 1970s a concept engine called the Bricklin-Turner [[Rotary Vee]] was tested.<ref>Popular Science August 1974</ref><ref>Popular Science April 1976</ref> The Rotary Vee is similar in configuration to the [[elbow engine|elbow steam engine]].  Piston pairs connect as solid V-shaped members, with each end floating in a pair of rotating cylinders clusters. The rotating cylinder cluster pairs are set with their axes at a wide V angle. The pistons in each cylinder cluster move parallel to each other instead of a radial direction, This engine design has not gone into production. The Rotary Vee was intended to power the [[Bricklin SV-1]].
