The BICh-3 (russian: БИЧ-3) was a tailless research aircraft designed and built in the
USSR
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen nationa ...
in 1926.
Development
After Cheranovsky's first tailless flying wing gliders, the
BICh-1 and
BICh-2, he continued developing the concept with the BICh-3. The BICh-3 was built of wood with a
parabolic wing
Parabolic usually refers to something in a shape of a parabola, but may also refer to a parable.
Parabolic may refer to:

having a straight trailing edge and a curved leading edge. The cockpit was faired into a large fin and rudder. The undercarriage consisted of a faired central mono-wheel with wing-tip skids.
The BICh-3 was flown in Moscow in 1926. It was found to be unstable in initial tests leading to modifications that improved the handling sufficiently for it to be cleared as safe to fly.
