The Tokyo Koku Aiba 11 was a 1940s Japanese civil transport aircraft derived from the Tokyo Koku Aiba 10 trainer. Its cabin accommodated three passengers on taxi or sight-seeing flights. Though well-regarded, developing military demands prevented its production.
The Aiba 11 was a Japanese civil aircraft developed from the Aiba 10, sharing the same engine and similar flying surfaces but with a new fuselage. Both types had wooden structures with a mixture of plywood- and fabric-covering.[1]
It was a single bay biplane, with fabric-covered wings of rectangular plan out to elliptical tips. The upper and lower wings were braced together with a pair of N-form interplane struts and the upper centre-section was joined to the fuselage with outward-leaning, N-form cabane struts.[1]
Though both the Aiba 10 and Aiba 11 had uncowled Gasuden Jimpu 3 seven cylinder radial engines mounted in the nose, the fuselages aft were very different. The Aiba 11's was flat-sided, with its three seat, windowed passenger cabin between the wings. It was flown from an open cockpit behind the cabin.[1]
Both had fixed, conventional undercarriages with wheels on split axles hinged just below the fuselage centre-line on short struts. Landing legs and forward drag struts were mounted on the lower fuselage longerons.[1]
The Aiba 11 was completed in June 1941 and flown soon after.[1]
