ASK by V.Ya.Krylov, I.M.Zharnylski, G.I.Bakshaev and L.S.Vilgrube

54k b/w ASK from "History of aircraft construction in the USSR", Vol.1 p.585

Original catamaran flying boat of wooden construction with single M-22 engine installed above the wing. Landing gear (retractable backwards) was attached to inner side of the hulls. Each hull has enclosed compartment for three passengers. Pilot's cockpit (open on the prototype) was located in small nacell on the wing center. Three tailfins were installed. Two-step hulls had 3 to 8mm thick plywood skin. Two-spar wing had plywood skin in the center and on outer panels - fabric.

Aircraft was built in Leningrad within GVF system. Intended for operations in Northern regions (so the ASK designation), it was designed and assembled in period 1933- 1935, and flown first time in Spring 1935 by pilots B.V.Glagolev and P.P.Skarandaev. ASK was flown on skis (from the ice), on wheels and from the water. Single minor accident involved broken landing gear.

In October 1936 ASK was damaged by flood. Pre-service continued after repair, but Autumn 1937 flood turned fatal for the project...
