A-1 and A-2 gliders by O.K.Antonov

42k b/w A-2 single-seater, "Russian aircraft since 1940", p.517

Pre-War Antonov-designed gliders (U-4 single-seater and U-6 two-seater) were revived in peace time as A-1 and A-2. Both had similar simple open-frame construction, all-wooden with wire bracing and fabric covering.

The A-1 was designed for bungee launching and had a detachable fuselage nacelle. Two-spar rectangular wing was of a constant chord. The leading edge was reinforced by ply planking to the front spar. Tail unit was tapered with rectangular controls. Wooden 2-wheel undercarriage incorporated single rubber shock absorber. It was fitted to the fuselage frame and could be replaced by alternative single-wheel one.

Slightly more sophisticated A-2 tandem two-seater was intended for winch launching or aero-towing. It was designed in 1942.

Both gliders have been produced in large numbers. Further development of this class has been undertaken by B.R.Oshkinis (BRO-9 and 11) and at the Kazan Aviation Institute (KAI-6,9,10,11).
