TheGrob G 110was a single-engined two-seat light aircraft, made mainly ofglassfibre,that was designed and built by the German manufacturerGrob Aircraftin the early 1980s. Two prototypes were built, with the first example making its maiden flight on 6 February 1982, but development was abandoned after the first prototype crashed later that year.
Design and development
[edit]In 1972, the German machine tool manufacturer, Burkhardt Grob Untermehnensbereich Maschinenbau, set up a subsidiary, Grob Flugzeugbau, to build aircraft. Grob Flugzeugbau started by buildingSchempp-Hirth Standard Cirrusgliders under license before switching to its own designs of gliders andmotor gliders.[1][2]In 1982 Grob revealed a more conventional powered light aircraft, the Grob G 110. This was a two-seat low-wingmonoplanesuitable for use as a training aircraft for flying clubs. It was powered by a singleLycoming O-235piston enginerated at 88 kW (118 hp) and had a fixedtricycle landing gear.Pilot and passenger sat side by side in an enclosed cabin. Grob had considerable experience in composite aircraft construction from its years of usingglassfibrein its Gliders, and the G 110 was largely built of glassfibre.[1][3][4]The wings used anairfoilsection designed to givelaminar flow,in order to improve performance.[5][6][7]
Two prototypes were built, with the first making its maiden flight on 6 February 1982. This aircraft crashed in August 1982 while testing the aircraft'sspinningcharacteristics, when it could not be recovered from aflat spin,thetest pilotescaping by parachute.[1][8][4]Although testing continued with the second prototype,[8]the type was abandoned without entering production with Grob designing a new two seat trainer, theGrob G 112.This too was a failure, as it was overweight, but the companies third attempt to enter the trainer market, theGrob G 115,flew in 1985.[4]
