27 February 1965: The first flight of the Antonov Design Bureau An-22 Antheus took place at Sviatoshyn Airfield, Kiev, Ukraine. The An-22 was the world’s largest airplane at the time, and it remains the world’s largest turboprop airplane.
The An-22 is 57.9 meters (190.0 feet) long with a wingspan of 64.40 meters (211.29 feet) and overall height of 12.53 meters (41.11 feet). The heavy-lift strategic transport has an empty weight of 114,000 kilograms (251,327 pounds) and maximum takeoff weight of 250,000 kilograms (551,156 pounds). It is powered by four Kuznetsov NK-12MA turboprop engines producing 15,000 horsepower, each, and which drive eight four-bladed, counter-rotating propellers.
The An-22 is operated by a flight crew of six and can carry 29 passengers, It’s payload capacity is 80,000 kilograms (176,370 pounds). It has a maximum speed of 740 kilometers per hour (460 miles per hour) and a range of 5,000 kilometers (3,107 miles) with a maximum payload.
Antonov produced 66 An-22 transports at the Tashkent Aircraft Production Corporation at Tashkent, Uzbekistan, between 1965 and 1976. 28 of these were the AN-22A variant. Several remain in service.
9 January 1943: At the insistence of the Army Air Forces, Boeing’s Chief Test Pilot, Eddie Allen, made the first flight of the Lockheed L-049 Constellation prototype, NX25600, from Lockheed Air Terminal at Burbank, California, to Muroc Army Airfield (today known as Edwards Air Force Base). Lockheed’s Chief Test Pilot, Milo G. Burcham, was the co-pilot.
When the flight ended after 58 minutes, Allen said, “This machine works so well that you don’t need me anymore!” With that, Allen returned to Seattle.
The Lockheed Model 49-46-10, company serial number 049-1961, was designated XC-69 by the U.S. Army Air Forces and assigned serial number 43-10309.
The Constellation was operated by a flight crew of four: two pilots, a navigator and a flight engineer. It could carry up to 81 passengers. The airplane was 95 feet, 3 inches (29.032 meters) long with a wingspan of 123 feet (37.490 meters) and an overall height of 23 feet, 8 inches (7.214 meters). It had an empty weight of 49,392 pounds (22,403.8 kilograms) and maximum takeoff weight of 86,250 pounds (39,122.3 kilograms).
The prototype was powered by four 3,347.66-cubic-inch-displacement (54.858 liter) air-cooled, supercharged, fuel-injected, Wright Aeronautical Division Cyclone 18 745C18BA3 (also referred to as the Duplex Cyclone), a two-row, 18-cylinder radial engine with a compression ratio of 6.5:1. They were rated at 2,000 horsepower at 2,400 r.p.m., or 2,200 horsepower at 2,800 r.p.m. for takeoff, (five minute limit) burning 100/130 aviation gasoline, and drove 15 foot, 2 inch (4.623 meter) diameter, three-bladed Hamilton Standard Hydromatic 43E60 constant-speed propellers through a 0.4375:1 gear reduction. The 745C18BA3 was 6 feet, 4.13 inches (1.934 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,842 pounds (1,289 kilograms). 41 of these engines were built by Wright.
The L-049 had a cruise speed of 313 miles per hour (504 kilometers per hour) and a range of 3,995 miles (6,429 kilometers). Its service ceiling was 25,300 feet (7,711 meters).
The prototype XC-69 was later re-engined with Pratt & Whitney Double Wasp 2SC14-G (R-2800-83) engines and designated XC-69E. These had a Normal rating of 1,700 horsepower at 2,600 r.p.m., to 7,300 feet (2,225 meters), 1,500 horsepower at 17,500 feet (5,334 meters), and 2,100 horsepower at 2,800 r.p.m. for Takeoff.
After the war, the Constellation prototype was sold to Howard Hughes’ Hughes Aircraft Company for $20,000 and registered as NX67900. In May 1950, Lockheed bought the prototype back from Hughes for $100,000 and it was again registered as NC25600. It had accumulated just 404 flight hours up to this time.
Lockheed then converted 049-1961 to a prototype for the L-1049 Super Constellation with another registration, NX6700. In 1952, it was once again converted, this time as an aerodynamic test aircraft for the U.S. Navy PO-1W radar early warning aircraft (later redesignated WV-1 and EC-121 Warning Star). It was also used to test the Allison YT56 turboprop engine by placing it in the #4 position.
Finally, in 1958, the first Constellation was purchased as a source of spare parts by California Airmotive Corporation and was dismantled.
23 December 1941: Although hundreds of Douglas DC-3 commercial transports had been impressed into military service directly from the production line and designated C-48, C-49 and C-50, the first airplane of the type specifically built as a military transport, C-47 Skytrain, 41-7722, made its first flight at Daugherty Field, Long Beach, California, on this date. More than 10,000 C-47s would follow. In service with the United States Navy, the Skytrain was designated R4D-1. In British service, it was called the Dakota Mk.I.
The primary differences between the civil and military airframes was the addition of a cargo door on the left side of the fuselage and a strengthened floor in the cabin.
The Douglas C-47 Skytrain is an all-metal twin-engine, low wing monoplane transport with retractable landing gear. It was operated by a minimum flight crew of two pilots, a navigator and a radio operator. The wing is fully cantilevered and the fuselage is of semi-monocoque construction. Control surfaces are fabric-covered.
The C-47 is 64 feet, 5½ inches (19.647 meters) long with a wingspan of 95 feet (28.956 meters) and height of 17 feet (5.182 meters). Empty weight of the C-47A is 17,257 pounds (7,828 kilograms) and the maximum takeoff weight is 29,300 pounds (13,290 kilograms).
The C-47 is powered by two 1,829.4-cubic-inch-displacement (29.978 liter) air-cooled, supercharged R-1830-92 (Pratt & Whitney Twin Wasp S1C3-G) two-row 14-cylinder radial engines. These had a maximum continuous rating for normal operation was 1,060 horsepower at 2,550 r.pm., up to 7,500 feet (2,286 meters), and 1,200 horsepower at 2,700 r.p.m., at Sea Level, for takeoff. Each engine drives a three-bladed Hamilton Standard Hydromatic constant-speed full-feathering propeller with a diameter of 11 feet, 6 inches (3.505 meters) through a 16:9 gear reduction. The R-1830-92 is 48.19 inches (1.224 meters) long, 61.67 inches (1.566 meters) in diameter, and weighs 1,465 pounds (665 kilograms).
The C-47 has a cruising speed of 185 miles per hour (298 kilometers per hour) at 10,000 feet (3,048 meters) and service ceiling of 24,100 feet (7,346 meters).
The C-47 could carry 6,000 pounds (2,722 kilograms) of cargo, or 28 fully-equipped paratroopers. Alternatively, 14 patients on stretchers could be carried, along with three attendants.
9 November 1944: Boeing’s senior test pilot, Albert Elliott Merrill, and co-pilot John Bernard Fornasero make the first flight of the Boeing Model 367 prototype, XC-97 43-27470.
Boeing built 888 C-97 Stratofreighters and KC-97 Stratotankers between 1947 and 1958. The type was finally retired from the U.S. Air Force in 1978. Another 56 Model 377 Stratocruisers civil transports were produced.
The Berlin Airlift officially ended on 30 September 1949, after fifteen months. In total the United States Air Force, Royal Air Force and Royal Australian Air Force delivered 2,334,374 tons, nearly two-thirds of which was coal, on 280,290 flights to Berlin.At the height of the Airlift, one plane reached West Berlin every thirty seconds.
