The BICh-14 (aka TsKB-10) was a twin-engined tailless sport / touring aircraft designed and built in the USSR from 1934.

Development

Further development of the BICh-7A led to an enlarged twin-engined version, a model of which was tested in a wind tunnel, as the BICh-10, with two M-11 engines on the leading edge of the parabolic wing either side of the cockpit nacelle. Full scale development emerged as the BICh-14, a 2x scaled up BICh-7A, with Townend Ring cowlings and up to five seats in the cabin. Construction was of wood with plywood and fabric skin or covering, four spars and sixty ribs. Flight testing began late in 1934 piloted by Yu. I. Piontkovskii, and later in Template:Avyear at the NII VVS by P.M. Stefanovskii, M.A. Nyukhtikov and I.F. Petrov. Results of the flight tests were not encouraging as the aircraft was found to have marginal control and stability, with high stick forces required to raise the nose on landing, as well as an in-effective rudder. Despite the shortcomings of the BICh-14 testing continued through to Template:Avyear.
