Boeing Model 299
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (later, the USAAF) promoted the aircraft ...

Martin XB-14
The Martin B-10 was the first all-metal monoplane bomber to be regularly used by the United States Army Air Corps, entering service in June 1934.Jackson 2003, p. 246. It was also the first mass-produced bomber whose performance was superior to that of the Army's pursuit aircraft of the time.Eden and Moeng 2002, p. 931. The B-10 served as the airframe for the B-12, B-13, B-14, A-15 and O-45 designations using Pratt & Whitney engines instead of Wright Cyclones. A total of 348 of all versions were built. The largest users were the US, with 166, and the Netherlands, with 121. Design and development The B-10 began a revolution in bomber design. Its all-metal monoplane airframe, along with its features of closed cockpits, rotating gun turrets (almost simultaneously with the 1933 British Boulton & Paul Overstrand biplane bomber's own enclosed nose-turret), retractable landing gear, internal bomb bay, and full engine cowlings, became the standard for bomber designs worldwide for de ...

Martin BM
The Martin BM was a 1930s American torpedo bomber built by the Glenn L. Martin Company for the United States Navy. Design and development To meet the requirement for a special-purpose dive bomber for the United States Navy and United States Marine Corps, the US Navy's Bureau of Aeronautics designed a biplane with fixed tailwheel landing gear, designated Bureau Design 77. It had room for two crew in tandem. Two prototypes were ordered in June 1928, one from Martin (designated the XT5M-1) and one from the Naval Aircraft Factory (designated the XT2N-1). The Martin XT5M-1 was powered by a Pratt & Whitney R-1690-22 Hornet radial engine, and, following test during 1930, the Navy ordered 12 aircraft from Martin with the designation BM-1. The BM-1 had a more powerful R-1690-44 engine. A further order for four was followed by an order for 16 for the BM-2. Martin moved to a new factory in Baltimore, Maryland, where the XT5M-1 was built, and it was first flown on 17 May 1929. During tes ...

Lockheed Model 14 Super Electra
The Lockheed Model 14 Super Electra was an American civil passenger and cargo aircraft built by the Lockheed Aircraft Corporation during the late 1930s. An outgrowth of the earlier Model 10 Electra, the Model 14 was also developed into larger, more capable civil and military versions. Design and development The design, developed by a team led by Don Palmer, was a scaled-up version of the original Model 10 Electra, with passenger seating increased from 10 to 14. It was intended to compete commercially with the contemporary Douglas DC-2 and the Boeing 247. The first Model 14 flew on July 29, 1937, piloted by Marshall Headle. Early 14's used the Pratt & Whitney R-1690 Hornet engine; later the Wright R-1820 Cyclone 9 was offered as an option. Lockheed built a total of 114 Model 14s; another 119 were built under license in Japan by the Tachikawa Aircraft Company under the designation Tachikawa Type LO Transport Aircraft ''Thelma''. Another 121 were built by Kawasaki Aircraft Compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keystone B-3
The Keystone B-3A was a bomber aircraft developed for the United States Army Air Corps by Keystone Aircraft in the late 1920s. Design and development The B-3 was originally ordered as the LB-10A (a single-tail modification of the Keystone LB-6), but the Army dropped the ''LB-'' 'light bomber' designation in 1930. Although the performance of the B-3A was hardly better than that of the bombers flown at the end of World War I, it had come a long way. In terms of its safety, it was far superior to its oldest predecessors. Operational history The B-3A was a member of the last family of biplanes operated by the US Army; it remained in service until 1940. A few years after it was first produced, the introduction of all-metal monoplanes rendered it almost completely obsolete. Variants ;LB-10 :The last of the 17 LB-6s ordered (S/N 29-27) was converted with a re-designed single fin and rudder and two 525 hp Wright R-1750E engines. Delivered to Wright Field on 7 July 1929, it was wreck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers W 34
The Junkers W 34 was a German-built, single-engine, passenger and transport aircraft. Developed in the 1920s, it was taken into service in 1926. The passenger version could take a pilot and five passengers. The aircraft was developed from the Junkers W 33. Further development led to the Junkers Ju 46. Production and service One Junkers W 34 be/b3e managed to break the then-current altitude record on 26 May 1929 when it reached . That aircraft carried the markings D-1119 and it was equipped with a Bristol Jupiter VII engine. The airplane was flown by Willi Neuenhofen. The Junkers W 34 was manufactured in many different versions. The total production numbers for the civil market were around 1,000, a further 2,024 his and haus were built under license for the RLM and ''Luftwaffe''. The unit price was between RM 65,000 and 70,400. On 31 January 1944 the ''Luftwaffe'' still had 618 W 34''his and 516 W 34haus in service: the majority were used by flight schools; mainly as nav ...

Junkers Ju 86
The Junkers Ju 86 was a German monoplane bomber and civilian airliner designed in the early 1930s, and employed by various air forces on both sides during World War II. The civilian model Ju 86B could carry ten passengers. Two were delivered to Swissair and five to Deutsche Luft Hansa. In addition a single civilian Ju 86Z was delivered to Sweden's AB Aerotransport. Design and development In 1934, a specification for a modern twin-engined aircraft, capable of operating both as a high-speed airliner for the German airline Luft Hansa and as a medium bomber for the nascent Luftwaffe, was issued to both Junkers and Heinkel. Five prototypes were ordered from each company; the Junkers Ju 86 and Heinkel He 111.Green and Swanborough 1982, p. 15. Junkers' design was a low-winged twin-engined monoplane, of all-metal stressed skin construction. Unlike most of Junkers' previous designs, it discarded the typical corrugated skinning in favour of smooth metal skinning which helped to reduce drag ...

Junkers Ju 52
The Junkers Ju 52/3m (nicknamed ''Tante Ju'' ("Aunt Ju") and ''Iron Annie'') is a transport aircraft that was designed and manufactured by German aviation company Junkers. Development of the Ju 52 commenced during 1930, headed by German Aerospace engineering, aeronautical engineer Ernst Zindel. The aircraft's design incorporated a wikt:corrugated, corrugated duralumin metal skin as a strengthening measure, which was very unusual at the time. The Ju 52's maiden flight was performed on 13 October 1930. It was initially designed with a single engine, however, it was produced in quantity as a trimotor. The primary early production model, the ''Ju 52/3m'', was principally operated as a 17-seat airliner or utility transport aircraft by various civil operators during the 1930s. Following the rise of Nazi Germany, thousands of Ju 52s were procured as a staple military transport of the nation. The ''Ju 52/3mg7e'' was the principal production model. The Ju 52 was in production between 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granville Gee Bee R-6
The Granville Gee Bee R-6 International Super Sportster, named "Q.E.D." (latin: ''quod erat demonstrandum'' "it is proven"), and later named "''Conquistador del Cielo''" (Spanish: "sky conqueror"), was the last in a series of racing and touring monoplane aircraft from the Granville Brothers. The R-6H was dogged with bad luck throughout its career and never finished any race it entered. Development Design work on the Gee Bee R-6 had begun in 1933, but the firm went bankrupt shortly afterwards in October 1933. Then, on 11 February 1934, Zanford Granville died in Spartanburg, South Carolina, when he crashed in the Gee Bee Model E Sportster he was delivering. This aircraft was intended to finance a new company to be based in New York called Granville, Miller & De Lackner. The R-6H would eventually be completed for Floyd B. Odlum, on behalf of Jacqueline Cochran for the MacRobertson Air Race in 1934. The touring aircraft was designed with large fuel tanks to handle the long legs ne ...

Granville Gee Bee Model R Super Sportster
The Gee Bee Model R Super Sportster was a special-purpose racing aircraft made by Granville Brothers Aircraft of Springfield, Massachusetts at the now-abandoned Springfield Airport. ''Gee Bee'' stands for Granville Brothers. Design and development The 1932 R-1 and its sister plane, the R-2, were the successors of the previous year's Thompson Trophy-winning Model Z. Assistant Chief Engineer Howell "Pete" Miller and Zantford "Granny" Granville spent three days of wind tunnel testing at NYU with aeronautical engineering professor Alexander Klemin. Granville reasoned that a teardrop-shaped fuselage would have lower drag than a straight-tapered one, so the fuselage was wider than the engine at its widest point (at the wing attachment point within the length of the wing chord). The cockpit was located very far aft, just in front of the vertical stabilizer, in order to give the racing pilot better vision while making crowded pylon turns. Operational history The R-1 won th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
