Light Transport Aircraft

C-39 in flight

First flight of DC-1, with 9-cylinder Wright SGR-1820-F radial engines rated at 690 hp each. with., took place on July 1, 1933. The plane could continue flying on one engine after takeoff and land at a high-altitude and hot airfield. By that time, Douglas had already received an order for 20 improved DC-2s, then increased to 31 machines.

DC-2 differed from DC-1 in its increased length by 0.61 m fuselage, respectively, the number of seats increased to 14, respectively, it was equipped with more powerful Wright Cyclone SGR-1820-F3 engines (710 hp each). everyone). Structurally, the aircraft was an all-metal low-wing aircraft with a semi-monocoque fuselage, a cantilever wing and tail unit, and a tricycle landing gear with a rotary tail wheel. The wheels of the main landing gear in the retracted position protruded somewhat from the niches in the engine nacelles, ensuring safety during a forced landing with the landing gear unreleased. The compartment between the pilot's cabin and the passenger compartment housed up to 454 kg of cargo or mail, another cargo compartment was located behind the passenger compartment. Access to the salon was through one door on the left side, there was a buffet right behind the entrance, and a toilet at the end of the salon.

The first DC-2, took off on May 11, 1934, and three days later was transferred to the TWA airline. The seats were located on the sides and were adjustable, with the ability to turn back. Each seat was located at the porthole, so there were seven of them on each side.

The Dutch "Fokker", the Japanese "Nakajima Hikoki KK" and the British "Airspeed" signed the licensing agreements for the release of DC-2. However, neither Fokker nor Airspeed built such aircraft - 39 aircraft were delivered, including 21 for the Dutch air carrier KLM, which operated the DC-2 on European routes and on the long-distance route between Holland and the Dutch East Indies. The Soviet company "Amtorg" acquired one DC-2, but did not acquire a license for an aircraft from the USSR.

For a little more than a year, 108 DC-2 aircraft were already in operation in 21 countries of the world, having flown more than 37 million km. An operator poll by Douglas showed that American operators and Pan American Airways in South America had flown 24,139,500 kilometers in the first eight months, operating at 98.8% efficiency.

The triumphant march of the future DC-3 has begun.

The US military ordered several DC-2s: five with 710 hp Wright engines. for the US Navy (under the designation R2D-1 were used as staff transport), and 18 vehicles were acquired by the US Army Air Corps under the designation C-33, they were operated as transport (they differed in increased keel and rudders, had a cargo door on the left side). In addition, 24 former civilian DC-2s entered the US Army Air Corps as the C-32A, the military received two personal transport YC-34s, and the C-38 prototype turned out to be a kind of combination of DC-2 and DC-3. One S-38 was equipped with two Wright R-1820-45 975 hp each. That is, it had a DC-3-type tail section and became the basis for the development and construction of 39 C-39 aircraft, which combined the C-33 fuselage and center section, tail section and chassis from DC-3. Two similar aircraft - C-41 with Pratt and Whitney R-1820-21 engines with 1200 hp each. and C-42 "Flying Chief" with Wright R-1820-53 1000 hp each. - were used by the command staff of the US Army Air Force.

Construction. All-metal cantilever low-wing aircraft of the classical design with two piston engines and retractable OOSh.

The landing gear retraction system is hydraulic. Thermostatic engine heating system with interior temperature control. Goodrich pneumatic anti-icing system on the leading edges of the wing and stabilizer. Liquid anti-icing system for propellers, carburetors and windows in the cockpit. The ventilation system of the passenger cabin.

The aircraft had modern instrumentation and radio navigation equipment. Radio station, Sperry autopilot, altimeter, speed indicator, artificial horizon, magnetic compass.

DC-3 in Ufa

DST (Douglas Sleeper Transport) with 16 berths, which made its maiden flight on December 17, 1935. There was, however, a 24-seat daytime version of this aircraft, designated DC-3. It was he who achieved thanks to his reliability, the dominant position on national airlines and popularity around the world. In the United States, 10,692 of these aircraft were produced; about 2000 more were built under license in the USSR under the designation Lisunov Li-2. The robust design of the DC-3 has led international airlines to readily purchase these beautiful machines.

A cantilever low-wing aircraft, the DC-3 had an all-metal construction, with the exception of the linen plating on the steering surfaces. A feature of its wing was the multi-spar design (borrowed from the DC-1). The aircraft had an all-metal fuselage of an almost circular cross-section, a retractable tricycle landing gear with a self-orienting tail wheel and a cantilever all-metal tail. Civilian DC-3s have played a huge role in establishing reliable national air routes. The record for the 1936-41 period, when US passenger traffic increased by almost 600%, was set in large part by the DC-3 aircraft, which at the time were equipped with most US airlines and whose safety was almost legendary.

Civilian models (including DST) were built in five series, and the standard powerplant was either Wright SGR-1820 or Pratt & Whitney Twin Wasp engines ranging from 1000 and 1200 hp. at different maximum takeoff weights.

To use the DC-3 as a military transport aircraft, the rear of the fuselage and the cockpit floor were reinforced, as well as equipped with large cargo doors. The power plant of the original production version consisted of two 895 kW (1200 hp) Pratt & Whitney R-1830-92 radial piston engines. Ordered in 1940, these aircraft received the designation C-47 Skytrain.

This aircraft is powered by Pratt & Whitney R1830 90D Twin Wasp 14-cylinder radial, 1200 hp. (895 kW) each.
The military version of this aircraft, the 1945 C-47V, had an increased fuel reserve and, accordingly, the flight range. This aircraft, after restoration, with installed modern business class seats and tables, does not have commercial passenger capacity and is rather an aircraft cabin.
October 20, 2019, a/p Ufa. The plane warmed up the engines for a long time in the parking lot, then at the executive start it hummed for a long time at takeoff, reluctantly ran several hundred meters, almost immediately raising its tail, and took off. Then a slow climb was like that. Next landing in Khakassia, in Abakan ...

On October 18, 2019, on the way to the PRC, at the Ufa airport, under the control of the KVS Patrick Moland, the American Douglas DC-3 of the Second World War landed. In the Middle Kingdom, they plan to make a "flying" museum out of it.
This aircraft, Douglas DC-3C S / N 33445, was converted from the military C-47-B Skytrain S / N 77113 5 11 of 1977. It was operated in the US Air Force, then in England and Canada, in the 1980s, this aircraft carried cargo in Africa, for which it was dubbed the "Queen of the Congo" ("Congo Queen"). For some time the plane flew in Europe, and then was under restoration in Sweden.
