A Rumanian Trainer: The I.A.R.22
CONSTRUCTED by the Societate Anonima Industria Aeronautica Romana, of Brasov, Rumania, the I.A.R.22 is a new type of school machine which has given very satisfactory results in tests before the Acceptance Commission
of the Rumanian Air Ministry. For normal flying training work the machine is fitted with a D.H. "Gipsy Major" engine of 130 h.p., but the fuselage and wing cellule have been made strong enough for almost any engine up to 300 h.p. to be fitted, which makes the machine suitable for instructional work with guns, camera and wireless.
The aircraft is a low-wing cantilever monoplane of wooden construction, the wing having two spruce box spars and webs of Okume plywood. Plywood covering is used over all the wing except the trailing edge, which is covered with fabric.
The fuselage is constructed as a Warren truss, the members being assembled by duralumin gussets. Plywood covering is used for covering the forward portion of the fuselage, and fabric for the remainder. Ball bearings are employed for all controls, and all the movable surfaces axe balanced. The engine mounting is of welded steel tubes, and the petrol tank, which is of the "droppable" variety, is of riveted duralumin.
"Airwheels," Palmer differentially-operated brakes and I.A.R. shock absorbers are used for the undercarriage.
