Lockheed Y1C-25
The Lockheed Altair was a single-engined sport aircraft produced by Lockheed Aircraft Limited in the 1930s. It was a development of the Lockheed Sirius with a retractable undercarriage, and was the first Lockheed aircraft and one of the first aircraft designs with a fully retractable undercarriage. Development and design Lockheed designed an alternative wing fitted with a retractable undercarriage for the Lockheed Sirius as a result of a request from Charles Lindbergh, although Lindbergh in the end chose to buy a standard Sirius. The first Altair, converted from a Sirius, flew in September 1930.Francillon 1982, p. 101. Like the Sirius, the Altair was a single-engined, low-winged monoplane of wooden construction. The undercarriage, which was operated by use of a hand crank, retracted inwards. Four Altairs following the prototype were converted from examples of the Sirius, with another six Altairs built from scratch: three by Lockheed, two by the Detroit Aircraft Corporation, and ...

Vega Aircraft Corporation
The Vega Aircraft Corporation was a subsidiary of the Lockheed Aircraft Company in Burbank, California responsible for much of its parent company's production in World War II. History The company was first formed in August 1937 as the AiRover Company to produce a new light aircraft design. It was renamed in May 1938 to honor Lockheed's first aircraft design, the Vega. The AiRover Model 1 was a Lockheed Altair fitted with a Menasco Unitwin 2-544 engine, which featured two engines driving a single shaft. The AiRover Model 2 was a new design named the Vega Starliner. One Starliner prototype was built and tested, but the design did not go into production. In 1940, with World War II already underway in Europe, Vega changed its focus from light aircraft to military aircraft. The company began by producing five North American NA-35 trainers under license with North American Aviation. Production by Vega really got underway with the Hudson, a patrol bomber designed for use by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockheed Model 9 Orion
The Lockheed Model 9 Orion is a single-engined passenger aircraft built in 1931 for commercial airlines. It was faster than any American military aircraft of that time. Designed by Richard A. von Hake, it was the last wood aircraft produced by the Lockheed Aircraft Corporation. Design The Orion was the last design using many identical elements from the Lockheed designs preceding it. It primarily used all the elements of the Lockheed Altair, Altair, but included a forward top cockpit similar to the Lockheed Vega, Vega, plus the NACA cowling introduced in the Lockheed Air Express, Air Express. Lockheed used the same basic fuselage mold and wing for all these wooden designs (the Lockheed Explorer, Explorer wing was unique), hence the close similarities between them. The Orion featured an enclosed cabin with seating for six passengers. The Orion received its Type certificate, Approved Type Certificate on 6 May 1931. Gerard F. Vultee was Lockheed's chief engineer in 1928 through 1931 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Explorer
The Lockheed Explorer was the least successful wooden airplane design produced by the Lockheed Aircraft Company. The Vega fuselage was combined with a cantilevered low wing. Seating for a single pilot was provided in an open cockpit behind the wings. Design and development Work on the Explorer was commenced in 1927 for Sir Hubert Wilkins as an aircraft for use in exploration of Antarctica. However, this configuration was judged impractical, and Wilkins opted to use a Vega equipped with floats instead. The incomplete aircraft was brought out of storage to make an attempt at a nonstop flight between Japan and the United States, funded by lumber dealer John Buffelen and members of the Tacoma Chamber of Commerce. Named ''City of Tacoma'', the first Pacific crossing attempt ended in disaster when overfilled fuel tanks spilled over on takeoff. Two subsequent attempts in newer Explorers also met with failure. The wing of a wrecked Explorer was fitted to the fuselage of an Orion by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Air Express
__NOTOC__ The Lockheed Air Express was the second aircraft design created by the Lockheed Aircraft Company after its founding in 1927; the type first flew in April 1928.Francillon 1982, p.85. Description The Air Express design incorporated the original fuselage of the Vega, but in order to meet the requirements of Western Air Express, the wing was raised to a parasol configuration above the fuselage and the cockpit was moved behind the wing, while a more powerful Pratt & Whitney Wasp engine was fitted to ease operations over the Sierra Nevada mountains.Francillon 1982, pp. 84–85. The design was a commercial success for the company although only seven were built, plus one Air Express Special. No Air Expresses have survived to the present day. One, registered NR3057, was flown by Roscoe Turner. Variants ;Lockheed 3 Air Express: Single-engined passenger and mail transport aircraft, seating between four and six passengers in an enclosed cabin, able to carry up to 1,000-lb ...

Lockheed Vega
The Lockheed Vega is an American five- to seven-seat high-wing monoplane airliner built by the Lockheed Corporation starting in 1927. It became famous for its use by a number of record-breaking pilots who were attracted to its high speed and long range. Amelia Earhart became the first woman to fly solo across the Atlantic Ocean in one, and Wiley Post used his to prove the existence of the jet stream after flying around the world twice. Design and development Designed by Jack Northrop, John Knudsen Northrop and Vultee Aircraft, Gerald Vultee, both of whom would later form their own companies, the aircraft was originally intended to serve with Lockheed's own airline routes. They set out to build a four-passenger (plus pilot) aircraft that was not only rugged, but also one of the fastest aircraft of its era. Using a wooden monocoque fuselage, plywood-covered cantilever wings and the best engine available, the Vega delivered on the promise of speed. The fuselage was built from she ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Pratt & Whitney R-1340
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating engine, reciprocating type that was widely used in United States, American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Pratt & Whitney Wasp series, Wasp series. It was a single-row, nine-cylinder (engine), cylinder, air-cooled engine, air-cooled, radial engine, radial design, and engine displacement, displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced. As well as numerous types of fixed-wing aircraft, it was used to power helicopters, the Agusta-Bell AB.102 and the Sikorsky H-19, and a class of airship, the K-class blimp. In 2016, it received designation as a List of Historic Mechanical Engineering Landmarks, Historic Engineering Landmark from the ASME, American Society of Mechanical Engineers.
