Boland V-8
The Boland V-8 was an aircraft engine that was developed by the Boland Brothers Frank Edward Boland (July 31, 1873 – January 3, 1913), James Paul Boland (August 20, 1882 – December 19, 1967) and Joseph John Boland (May 27, 1879 – September 12, 1964) were early aircraft designers from Rahway, New Jersey who started ... for use in their tailless aircraft. Between 1908 and 1914, four versions of this motor were produced ranging in power from to . The Boland motors all used an unusual concentric overhead valve. This arrangement positioned the intake valve in the middle of the exhaust valve. These were actuated by a single push rod and rocker arm. Variants ;60 HP :The prototype of this motor first appeared in a Boland aircraft 1908. According to a Boland advertisement from 1911, they claimed that this single original motor powered all of the various iterations of the early Boland aircraft for three years without the need for repair or rebuild ;70 HP :Bore: , Stroke: , Di ...

Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intr ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Boland 1911 Tailless Biplane
The Boland 1911 Tailless Biplane was an American pioneering aircraft. At the end of 1909, Wilbur R. Kimball bought Dr. William Greene's 1909 biplane and took it to Rahway, New Jersey where he and Frank Boland removed the tail and began experimenting with a novel control system that eventually led to the first Boland Brothers 'jibbed' tailless biplane. Design and development Frank Boland was convinced that a traditional tail rudder and ailerons/wing warping was unnecessary to provide lateral control for an airplane. He started experimenting with different control mechanisms in 1908. More enthusiastic and daring than skilled engineer, Boland and Kimball spent 1910 experimenting with, crashing and rebuilding the Greene biplane while they worked out and refined what Boland called the 'jibbed' control. The resulting airplane was very easy to fly. To go left or right, you would turn the wheel in the direction you wished to go and up and down was controlled by pushing and pull ...

Boland 1911 Conventional Biplane
The Boland 1911 Conventional Biplane was an American pioneering aircraft. During the winter of 1911-1912, Frank Boland built a conventional pusher biplane. Boland built this aircraft to compare it with the tailless aircraft that he'd been building for the 3 previous years. Design and development Frank Boland wanted to make sure that he fully understood the dynamics of a conventional biplane so, in the winter of 1911-12, he constructed an aircraft of his own design in Mineola, Long Island Mineola is a Administrative divisions of New York#Village, village in and the county seat of Nassau County, New York, Nassau County, on Long Island, in New York (state), New York, United States. The population was 18,799 at the 2010 census. The n .... This conventional pusher biplane had an interconnected forward and rear elevator. A movable rudder is mounted in the rear. Roll control was achieved using wing warping. Boland used this aircraft to contrast with the performance of his uno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boland 1912 Tailless Biplane
The Boland 1912 Tailless Biplane was a refinement of the Boland 1911 Tailless Biplane. The major change in the 1912 biplane is the addition of a central nacelle that contained the pilot, passenger and the engine. Design and development The Boland 1912 biplane was more of a refinement of Frank Boland's previous tailless aircraft. Still using the wing 'jibs' he developed for lateral control, this aircraft introduced a crudely constructed nacelle for the pilot, passenger and engine. This was the aircraft that Boland took on tour to Venezuela and the West Indies in 1912, becoming the first person to fly an aircraft in Venezuela. It was also the aircraft he was flying in Port of Spain, Trinidad Port of Spain (Spanish: ''Puerto España''), officially the City of Port of Spain (also stylized Port-of-Spain), is the capital of Trinidad and Tobago and the third largest municipality, after Chaguanas and San Fernando.

Boland 1914 Monoplane Flying Boat
The Boland 1914 Monoplane Flying Boat was a tailless, pusher flying boat built by the Boland Aeroplane and Motor Company Design and development This aircraft was the only monoplane development from the Boland brothers that used their unusual 'jib' method of lateral control. The pilot and passenger were arranged in tandem, with the pilot in the forward position and the passenger seated to the rear, directly over the center of gravity of the aircraft. A small cockpit fairing was located in front of the pilot. The hull was a narrow two step, flat bottom design that was slightly concave in the rear most section. The hull was almost rectangular in section. It was constructed of mahogany ribs with a single ply spruce skin covered in doped and varnished linen. A small, rectangular rudder was mounted under the rear of the hull to provide steerage in the water. The wings were mounted above the hull. A lightweight cantilever structure extended from the hull to provide the lower suppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
