VFW-Fokkers' Rhein-Flugzeugbau subsidiary is now flight testing the Sirius II in its investigation of integrated ducted fan propulsion. First flown on 18 January 1972, Sirius II has two 30 hp Fichtel & Sachs Wankel-type engines driving the high-speed propeller that is contained in a duct forming an integral part of fuselage design, and the wing and tail unit of a Caproni Vizzola Calif A 21 sailplane. Use of Wankel type engines makes intermediate gears unnecessary and two-engined reliability is achieved with a single propeller.
