Keystone XLB-3
The Keystone XLB-3 (originally built under the Huff-Daland name) was a prototype bomber biplane developed in the United States in the late 1920s. It was a twin-engine development of the single-engine LB-1, brought about by a change in policy by the United States Army Air Corps (USAAC). Design and development The shift from a nose-mounted engine to engines mounted in nacelles on the lower wing created an opportunity to provide stations for two extra crewmembers: a bombardier and a nose-gunner, bringing the total to five. The LB-1's single tailfin and rudder was augmented by an extra rudder either side of it. Operational history A single prototype was constructed, and delivered to the USAAC for evaluation at the end of 1927. Evaluation, however, showed that performance was actually inferior to that of the single-engine LB-1. The decision was taken to change the XLB-3's air-cooled inverted Liberty engines for air-cooled radials, at which point it was redesignated XLB-3A. With perf ...

Light Bomber
A light bomber is a relatively small and fast type of military bomber aircraft that was primarily employed before the 1950s. Such aircraft would typically not carry more than one ton of ordnance. The earliest light bombers were intended to drop their bombs in level flight over a target. During World War I some air forces began to distinguish between light bombers and the earliest purpose-built attack aircraft which carried out ground attack, close air support, anti-shipping and similar missions. After World War I, attack aircraft were typically identifiable by their ability to carry multiple fixed machine guns, automatic cannons and rockets in addition to bombs. Light bombers have often served as attack aircraft and vice versa. Purpose-built light bombers disappeared from military aviation by the end of World War II, as advancements in propulsion and aeronautical design enabled newer attack/strike aircraft, fighter-bombers, and multirole aircraft types to deliver equal ...

Keystone Aircraft
Keystone Aircraft Corporation was an early American airplane manufacturer. History Headquartered in Bristol, Pennsylvania, the company was formed as "Ogdensburg Aeroway Corp" in 1920 by Thomas Huff and Elliot Daland, but its name was quickly changed to " Huff-Daland Aero Corp", then to "Huff-Daland Aero Company". The company made a name for itself in agricultural aircraft, and then in the United States Army Air Corps' early bomber aircraft. From 1924, James McDonnell was the chief designer. In 1926, Huff left the company, and it was soon purchased by Hayden, Stone & Co., who increased capital to $1 million (United States) and renamed it Keystone. In 1928, it merged with Loening and was known as Keystone–Loening. In 1929, it was taken over by Curtiss-Wright. Also in 1929, the Keystone–Loening plant on the East River in New York City was closed by Curtis-Wright and the operation was moved to the Bristol, Pennsylvania. Keystone plant.

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the Department of the Air Force.

Huff-Daland LB-1
The Huff-Daland LB-1 was an American biplane light bomber aircraft operated by the United States Army Air Service in the 1920s. Derived from the XLB-1 prototype bought by the Army in 1923, the LB-1 development aircraft was powered by a single Packard 2A-2500 engine and carried an extra crewman. It proved underpowered in service trials, and was replaced by the twin-engined XLB-3. Variants ;XLB-1: Prototype aircraft, powered by an 800-hp (597-kW) Packard 1A-2500 piston engine; one built (S/N 23-1250). ;LB-1: Single-engine light bomber biplane, powered by an 800-hp (597-kW) Packard 2A-2500 piston engine; nine built (S/N 26-377/385).

Keystone LB-5
The Keystone LB-5 (originally ordered under the Huff-Daland name) was a bomber aircraft produced in the United States in the late 1920s. Its manufacturer nicknamed it the Pirate, but this name was not officially adopted by the United States Army Air Corps (USAAC). Design and development The LB-5 was a member of the family of closely related bomber designs that had debuted with the XLB-1 in 1923, and as such, was a large, single-bay, conventional biplane. Like most of the family, it was a twin-engine machine, with engines mounted in nacelles on the lower wing. The prototype XLB-5 had a single tail fin like the XLB-1, the 10 LB-5 production machines were designed with a triple-finned tail under the Huff-Daland name, but the final batch of 25 was redesigned with twin tails and designated LB-5A. Operational history Its Liberty L-12 engines featured duralumin adjustable-pitch propellers built by the Standard Steel Propeller Company of Pittsburgh, Pennsylvania, (forerunner of the ...

Allison VG-1410
The Liberty L-12 is an American water-cooled 45° V-12 aircraft engine displacing and making designed for a high power-to-weight ratio and ease of mass production. It saw wide use in aero applications, and, once marinized, in marine use both in racing and runabout boats. A single bank 6-cylinder version, the Liberty L-6, and V-8, the Liberty L-8, were derived from the Liberty L-12. It was succeeded by the Packard 1A-2500. Development In May 1917, a month after the United States had declared war on Germany, a federal task force known as the Aircraft Production Board summoned two top engine designers, Jesse G. Vincent (of the Packard Motor Car Company of Detroit) and Elbert J. Hall (of the Hall-Scott Motor Co. in Berkeley, California), to Washington, D.C. They were given the task of designing as rapidly as possible an aircraft engine that would rival if not surpass those of Great Britain, France, and Germany. The Board specified that the engine would have a high power-to-wei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney R-1340
The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine-cylinder, air-cooled, radial design, and 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 Historic Engineering Landmark from the American Society of Mechanical Engineers.

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

Huff-Daland Aircraft
Huff-Daland was an American aircraft manufacturer. Formed as Ogdensburg Aeroway Corp in 1920 in Ogdensburg, New York by Thomas Huff and Elliot Daland, its name was quickly changed to Huff-Daland Aero Corp and then in 1925 it was changed again to Huff-Daland Aero Company with its main headquarters in Bristol, Pennsylvania. Huff-Daland produced a series of biplanes as trainers, observation planes, and light bombers for the U.S. Army and Navy. From 1923-1924, Huff-Daland developed the first aircraft designed for crop dusting and began selling and promoting the new service through a subsidiary Huff Daland Dusters founded on March 2, 1925. Though acquisitions beginning in 1928, the dusting subsidiary became a founding component of Delta Air Lines. In 1927, the corporation was taken over by Hayden, Stone & Company, a New York City brokerage firm and in the course of the merger it became the Huff-Daland Division of the Keystone Aircraft Corporation.
