Berliner Helicopter
The Berliner Helicopter was a series of experimental helicopters built by Henry Berliner between 1922 and 1925. The helicopters had only limited controllability but were the most significant step forward in helicopter design in the US, until the production of the Vought-Sikorsky VS-300 helicopter in 1940. The 1922 flights of the Berliner and the de Bothezat H1 were the first by manned helicopters.''The Helicopter: A Hundred Years of Hovering'' Wired.com.

Henry Berliner
Henry Adler Berliner (December 13, 1895 – May 1, 1970) was a United States aircraft and helicopter pioneer. Sixth son of inventor Emile Berliner, he was born in Washington, D.C. He studied mechanical engineering at Cornell University for two years before attending Massachusetts Institute of Technology. After a short time as aerial photographer with the Army Air Service, in 1919 Henry moved back to Washington to help his father with the helicopter research that had been underway for many years (since 1903 New International Encyclopedia). Using a Le Rhône engine of 80 hp mounted on a test stand, Henry was able to hover and move forward, but only with assistants holding on to stabilize the contraption. In 1922, he bought a surplus Nieuport 23 fighter's fuselage, added a Bentley 220 hp engine on the front, and connected it by geared shafts to two horizontal rotors mounted on a truss extending sideways from the fuselage. A third horizontal rotor at the rear provided pit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Popular Mechanics
''Popular Mechanics'' (sometimes PM or PopMech) is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do-it-yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured. It was founded in 1902 by Henry Haven Windsor, who was the editor and—as owner of the Popular Mechanics Company—the publisher. For decades, the tagline of the monthly magazine was "Written so you can understand it." In 1958, PM was purchased by the Hearst Corporation, now Hearst Communications. In 2013, the US edition changed from twelve to ten issues per year, and in 2014 the tagline was changed to "How your world works." The magazine added a podcast in recent years, including regular features ''Most Useful Podcast Ever'' and ''How Your World Works''. History ''Popular Mechanics'' was founded in Chicago by Henry Haven Windsor, with the first issue dated January 11, 1902. ...

Pescara Model 3 Helicopter
The Pescara Model 3 was the first of several coaxial helicopter designs by Raúl Pateras Pescara to demonstrate sustained controlled helicopter flight. Development Argentinian engineer Pescara started helicopter development in 1916. Alberto Santos-Dumont helped fund experimentation on designs in France. Multiple examples were built, demonstrated, crashed, improved and rebuilt owing to conflicting and different names for the various versions. Anticipating success with the counter-rotating mechanism, Pescara patented a design with a streamlined fuselage with one set of rotors above, and one below the fuselage. The model three was the first example to use control mechanisms as modern helicopters. The helicopter is based around a central shaft with counter-rotating rotors. Each rotor was doubled into a biplane arrangement with cable supports. It used a cyclic stick for forward and lateral control with rotor warping, and wheel for yaw anti-torque control. The main rotor shaft was able ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Bothezat Helicopter
The de Bothezat helicopter, also known as the Jerome-de Bothezat Flying Octopus, was an experimental quadrotor helicopter built for the United States Army Air Service by George de Bothezat in the early 1920s, and was said at the time to be the first successful helicopter. Although its four massive six-bladed rotors allowed the craft to successfully fly, it suffered from complexity, control difficulties, and high pilot workload, and was reportedly only capable of forward flight in a favorable wind. The Army canceled the program in 1924, and the aircraft was scrapped. Development and testing Self-described as "the world's greatest scientist and outstanding mathematician",Young 1982, p. 36. and having written one of the first scientific papers on the aerodynamics of rotary-wing flight, George de Bothezat was a refugee from the Russian Empire who had fled to the United States in the wake of the Russian Revolution. Having written and lectured extensively on rotorcraft theory, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentley BR2
The Bentley B.R.2 was a nine-cylinder British rotary aircraft engine developed during the First World War by the motor car engine designer W. O. Bentley from his earlier Bentley BR.1. Coming as it did near the end of the war, the BR.2 was built in smaller numbers than the earlier BR.1 – its main use being by the Royal Air Force in the early 1920s. Design and development The initial variant of the BR.2 developed , with nine cylinders measuring for a total displacement of 1,522 cubic inches (24.9 L). It weighed , only more than the Bentley B.R.1 (A.R.1). This was the last type of rotary engine to be adopted by the RAF – later air-cooled aircraft engines such as the Cosmos Jupiter and Armstrong Siddeley Jaguar being almost entirely of the fixed radial type. With the BR.2, the rotary engine had reached a point beyond which this type of engine could not be further developed, due to its inherent limitations. Applications The type selected as the standard single-seat fighter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
College Park Aviation Museum
College Park Airport is a public airport located in the City of College Park, in Prince George's County, Maryland, United States. It is the world's oldest continuously operated airport. The airport is located south of Paint Branch and Lake Artemesia, east of U.S. Route 1 and the College Park Metro/MARC station and west of Kenilworth Avenue. History College Park Airport was established in August 1909 by the United States Army Signal Corps to serve as a training location for Wilbur Wright to instruct two military officers to fly in the government's first airplane. Leased on August 25, the first airplane, a Wright Type A biplane, was uncrated and assembled on October 7. Civilian aircraft began flying from College Park Airport as early as December 1911, making it the world's oldest continuously operated airport. In 1977, the airport was added to the National Register of Historic Places. College Park Airport is home to many "firsts" in aviation, and is particularly significant f ...

Smithsonian Air And Space Museum
The National Air and Space Museum of the Smithsonian Institution, also called the Air and Space Museum, is a museum in Washington, D.C., in the United States. Established in 1946 as the National Air Museum, it opened its main building on the National Mall near L'Enfant Plaza in 1976. In 2018, the museum saw about 6.2 million visitors, making it the fifth-most-visited museum in the world, and the second-most-visited museum in the United States.
