Design
The Ka-22 was in essence a fixed-wing aircraft with rotors fitted above the wing tips. An engine was mounted on each wing tip, with drive to both a forward-pulling four-blade propeller and a vertical four-blade rotor. The rotors were larger derivatives of those fitted to the Mi-4. The original prototype was powered by 5,900shp Kuznetsov TV-2VK engines, although these were later replaced by the 5,500shp Soloviev D-25VK. The fuselage contained three-seat cockpit above the glazed nose and a main cargo area large enough to contain 80 seats or 16.5 tonnes of cargo. The entire nose could swing open to starboard for loading bulky items. In helicopter mode the propeller drive was disconnected and the flaps were lowered to 90 degrees. In fixed-wing mode, the lifting rotors were free to windmill, and the aircraft was controlled by the ailerons and tail surfaces. The twin-wheel landing gear was fixed.

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
