The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of 1,000–1,200 hp (750–890 kW). Although the DC-3s originally built for civil service had the Wright R-1820 Cyclone, later civilian DC-3s used the Pratt & Whitney R-1830 Twin Wasp engine. The DC-3 has a cruising speed of 207 mph (333 km/h), a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of 1,500 mi (2,400 km), and can operate from short runways.
The Grumman S-2 Tracker was the first purpose-built, single airframe anti-submarine warfare (ASW) aircraft to enter service with the United States Navy. Designed and initially built by Grumman, the Tracker was of conventional design — propeller-driven with twin radial engines, a high wing that could be folded for storage on aircraft carriers, and tricycle undercarriage. The type was exported to a number of navies around the world. Introduced in 1952, the Tracker and its E-1 Tracer derivative saw service in the U.S. Navy until the mid-1970s, and its C-1 Trader derivative until the mid-1980s, with a few aircraft remaining in service with other air arms into the 21st century. Argentina is the last country to still operate the Tracker.
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner.
The Douglas C-47 Skytrain or Dakota is a military transport aircraft developed from the civilian Douglas DC-3 airliner. It was used extensively by the Allies during World War II. During the war the C-47 was used for troop transport, cargo, paratrooper, for towing gliders and military cargo parachute drops. The C-47 remained in front-line service with various military operators for many years. It was produced in approximately triple the numbers as the larger, much heavier payload Curtiss C-46 Commando, which filled a similar role for the U.S. military.
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since. The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, which had logged 400 million flight hours from 1963 to 2016. It is known for its reliability, with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A turboprop engine covers the power range between 580 and 1,940 shp, while the PT6B/C are turboshaft variants for helicopters.
The Douglas DC-5 was a 16-to-22-seat, twin-engine propeller aircraft intended for shorter routes than the Douglas DC-3 or Douglas DC-4. By the time it entered commercial service in 1940, many airlines were canceling orders for aircraft. Consequently, only five civilian DC-5s were built. With the Douglas Aircraft Company already converting to World War II military production, the DC-5 was soon overtaken by world events, although a limited number of military variants were produced.
The Rolls-Royce RB.53 Dart is a turboprop engine designed and manufactured by Rolls-Royce Limited. First run in 1946, it powered the Vickers Viscount on its maiden flight in 1948. A flight on July 29 of that year, which carried 14 paying passengers between Northolt and Paris–Le Bourget Airport in a Dart-powered Viscount, was the first regularly scheduled airline flight by a turbine-powered aircraft. The Viscount was the first turboprop-powered aircraft to enter airline service - British European Airways (BEA) in 1953.
The North American Aviation XA2J "Super Savage" was a prototype carrier-based attack aircraft built in the early 1950s. It was developed by North American Aviation (NAA) from the smaller AJ Savage.
The Grumman G-164 Ag Cat is a single-engined biplane agricultural aircraft, developed by Grumman in the 1950s.
The Handley Page HPR.7 Dart Herald is a British turboprop passenger aircraft, designed in the 1950s as a DC-3 replacement, but only entering service in the 1960s by which time it faced stiff competition from Fokker and Avro. Sales were disappointing, contributing in part to the demise of Handley Page in 1970.
The Convair CV-240 is an American airliner that Convair manufactured from 1947 to 1954, initially as a possible replacement for the ubiquitous Douglas DC-3. Featuring a more modern design with cabin pressurization, the 240 series made some inroads as a commercial airliner, and had a long development cycle that produced various civil and military variants. Though reduced in numbers by attrition, various forms of the "Convairliners" continue to fly in the 21st century.
The Basler BT-67 is a utility aircraft produced by Basler Turbo Conversions of Oshkosh, Wisconsin. It is a remanufactured and modified Douglas C-47 Skytrain / Douglas DC-3; the modifications are designed to significantly extend the DC-3's serviceable lifetime.
Conroy Aircraft was an American aircraft manufacturer founded by John M. Conroy in Goleta, California, in 1968 after he resigned as president of Aero Spacelines. The company imitated Aero Spacelines' success with its Guppy aircraft by converting a Canadair CL-44 to carry oversized cargo as the Conroy Skymonster.
The Conroy Tri-Turbo-Three was a Douglas DC-3 fitted with three Pratt & Whitney Canada PT6A turboprop engines by Conroy Aircraft; the third engine was mounted on the nose of the aircraft.
The Lockheed C-121 Constellation is a military transport version of the Lockheed Constellation. A total of 332 aircraft were constructed for both the United States Air Force and United States Navy for various purposes. Numerous airborne early warning versions were also constructed. The C-121 later saw service with smaller civilian operators until 1993.
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The aircraft was colloquially referred to as the Super Connie.
The Lockheed L-749 Constellation is the first Lockheed Constellation to regularly cross the Atlantic Ocean non-stop. Although similar in appearance to the L-649 before it, the L-749 had a larger fuel capacity, strengthened landing gear, and eventually weather radar.
A power-egg is a complete "unitized" modular engine installation, consisting of engine and all ancillary equipment, which can be swapped between suitably designed equipment, with standardised quick-changing attachment points and connectors.
The Douglas R4D-8 is a military transport aircraft developed from the civilian Douglas DC-3S airliner. It was used by the United States Navy and United States Marine Corps during the Korean War and Vietnam War.
