In 1933 Putilov started the design of a flying wing 18 passenger transport with the intention of achieving very high levels of efficiency. The broad rectangular centre section housed the cabin and a fully glazed cockpit on the centre line, with long and shallow fins at its extremities and a large elevator at the trailing edge. The tapered outer wings carried the slotted flaps and ailerons. The structure was to be entirely formed from ''Enerzh-6'' stainless steel tubing and rolled sections covered with bakelite-impregnated ply (similar to ''Delta-wood'') on the centre section and fabric elsewhere. Structural test specimens were tested, including a complete wing spar, and a 1/4 scale model powered by two
