Boeing 314 Clipper
The Boeing 314 Clipper was an American long-range flying boat produced by Boeing from 1938 to 1941. One of the largest aircraft of its time, it had the range to cross the Atlantic and Pacific oceans. For its wing, Boeing re-used the design from the earlier XB-15 bomber prototype. Twelve Clippers were built, nine of which served with Pan Am. It was the first aircraft to carry a sitting American president, when in 1943 Franklin D. Roosevelt flew from Miami to the Casablanca Conference in Morocco, via Trinidad, Brazil, and The Gambia. Development Background As early as 1935 Pan American had identified that a truly trans-Pacific flying boat with unprecedented range and double the passenger payload of the airline's Martin M-130 would be required particularly if they were to provide a service across the longer more difficult Atlantic route and requested proposals from a number of American manufacturers.Trautman, pp. 54-56 In February 1936, not long after the M-130s were introduce ...

Pratt & Whitney R-1830 Twin Wasp
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It has 14 cylinders, arranged in two rings of seven. It displaces and its bore and stroke are both . The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s. It was selected as the power plant for both the four-engined Consolidated B-24 Liberator heavy bomber and the twin-engined Douglas DC-3 transport, two of the most-produced aircraft. The production run of 173,618 R-1830 examples makes it the most-produced aviation engine in history. A further developed version, the R-2000, was produced starting in 1942. The R-2000 was "bored-out" to and had a number of other minor changes to improve fuel economy and allow it to run at higher power ratings on lower-octane fuel. The primary user of the R-2000 was the Douglas DC-4. Mostly retired today, the R-1830 is still used on Douglas DC-3 and va ...

Wright R-2600 Twin Cyclone
The Wright R-2600 Cyclone 14 (also called Twin Cyclone) is an American radial engine developed by Curtiss-Wright, and widely used in aircraft in the 1930s and 1940s. History In 1935, Curtiss-Wright began work on a more powerful version of their successful R-1820 Cyclone 9. The result was the R-2600 Twin Cyclone, with 14 cylinders arranged in two rows. The R-2600-3 was originally intended for the C-46 Commando (being fitted to the prototype CW-20A). It was also the original engine choice for the F6F Hellcat; a running change (one which would not stop production) for the CW-20A, and one in late April 1942 for the second XF6F-1, led to the adoption of the Pratt & Whitney R-2800 Double Wasp in the R-2600's place for both designs. The Twin Cyclone went on to power several important American World War II aircraft, including the A-20 Havoc, B-25 Mitchell, TBF Avenger, SB2C Helldiver, and the PBM Mariner. Over 50,000 R-2600s were built at plants in Paterson, New Jersey, and Cinci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind-tunnel
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. In this w ...

Boeing XB-15
The Boeing XB-15 (Boeing 294) was a United States bomber aircraft designed in 1934 as a test for the United States Army Air Corps (USAAC) to see if it would be possible to build a heavy bomber with a range. For a year beginning in mid-1935 it was designated the XBLR-1. When it first flew in 1937, it was the most massive and voluminous airplane ever built in the US. It set a number of load-to-altitude records for land-based aircraft, including carrying a payload to on 30 July 1939. The aircraft's immense size allowed flight engineers to enter the wing through a crawlway and make minor repairs in flight. A flight took 33 hours at its cruising speed; the crew was made up of several shifts, and bunks allowed them to sleep when off duty. Design and development The specification that produced the XB-15 began in mid-1933 as "Project A", USAAC discussions regarding the possibility of flying a very large bomber with a range of . In April 1934, the USAAC contracted with Boeing and M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-45
The Sikorsky S-45 was a proposed Double-deck aircraft, double-deck transoceanic flying boat originally designed in 1938 by Sikorsky Aircraft for Pan Am. The high wing monoplane featured a single-step hull (watercraft), hull with a triple-tail and was to be powered by six Wright R-3350 Duplex-Cyclone engines which were being developed at the time. The aircraft would have competed with the Boeing 314 Clipper, Boeing 314 but no examples of the S-45 were ever manufactured.

Martin 156
The Martin 156, referred to in the press variously as the "Russian Clipper", "Moscow Clipper", or "Soviet Clipper" was a very large flying boat aircraft intended for trans-Pacific service. The single example of the M-156 was designed and built in response to a request from Pan American Airways to provide a longer-range replacement for the Martin M-130. Design and development Martin delivered three Martin Ocean Transport Model-130s (M-130) to Pan Am in 1935 which were flown as the ''China Clipper'', '' Philippine Clipper'' and ''Hawaii Clipper''. Pan Am rejected the M-156 in preference to the Boeing 314 for its replacement. Pan Am was seeking to expand its trans-Pacific air service between San Francisco and Hong Kong in 1937. This route had been pioneered by the Martin M-130 and Pan Am was in need of a larger aircraft. The San Francisco to Hawaii flight was and took 18 to 20 hours. Pan Am would have configured the M-156 as a 26-berth sleeper. The trans-Pacific flights flying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Consolidated Aircraft
The Consolidated Aircraft Corporation was founded in 1923 in aviation, 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors.Yenne 2009, p. 15. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Asiatic-Pacific Theater, Pacific and European Theater of Operations, European theaters. In 1943 in aviation, 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair. The Los Angeles-based Consolidated Steel Corporation is not related.
