The aircraft was designed by F. Fecher in the
Akaflieg (academic group of flyers) of
Technische Universität Darmstadt. It was a development of
Darmstadt D-18, slightly enlarged, more streamlined and fitted with an inline engine. Thanks to strengthening it was better fit to aerobatics. Two were built in 1931. Just like the D-18, the D-22 was a cantilever biplane, with an upper wing placed low above a fuselage and ahead of a lower wing. Aerodynamic cleanliness and low weight were emphasised in the design, resulting in a small aircraft with clean lines.
Description The D-22 was of wooden construction with
cantilever biplane and oval cross-section fuselage skinned with plywood and fabric on parts of the single-spar wings, which could be dismounted and folded rearwards. The two crew sat in open cockpits in tandem, with windshields. The
landing gear was fixed with a rear fuselage skid. The engine was mounted in the fuselage nose and drove a two-bladed fixed-pitch propeller. Fuel was supplied from a tank in the fuselage. ==Operational history==
