The Ruschmeyer R 90 is a four-seat light aircraft designed and produced in Germany in the late 1980s and early 1990s.
Design and development
MF-85
Ruschmeyer Luftfahrttechnik initially designed the Ruschmeyer MF-85, intended to be powered by Porsche PFM 3200 derivatives, which was debuted at the 1987 Hannover Air Show. The MF-85 was a composite four seat aircraft, planned to be offered with Script error: No such module "convert". engines, priced at DM245,000 to DM325,000 (excluding avionics), with optional fixed or retractable undercarriage. The prototype (V001 D-EEHE) first flew with a Script error: No such module "convert". Porsche PFM 3200N, driving a 3-bladed Mühlbauer MTV.9 constant speed propeller, on 8 August 1988, piloted by Horst Ruschmeyer. The second and third aircraft, V002 (D-EERO) and V003 (D-EERH), on flew on 23 September 1990 and 12 February 1992 respectively. Despite promising flight test results, the unavailability of Porsche engines led to the development of the Textron Lycoming powered R 90.
R 90
Powered by a Lycoming IO-540-C4D5 driving a Mühlbauer MTV.14-B constant speed propeller, the production R 90-230RG was built from 1988 to the mid-1990s in Germany. The engine is de-rated to Script error: No such module "convert". to reduce noise, but still enables the R 90 to reach a maximum cruising speed of Script error: No such module "convert"..
German certification was awarded in June 1992, with 28 production aircraft built when Ruschmeyer Luftfahrttechnik filed for bankruptcy in June 1996.[2] In 1999, the assets of Ruschmeyer were purchased by Solaris Aviation of West Palm Beach, Florida, marketing the R90 as the Solaris Sigma.[2][3] In 2004, the project passed to Aircraft Technology Consulting, which restarted production in Germany, building two more aircraft by mid 2005.[2]
