Brantly B-1
The Brantly B-1 was a 2-seat, coaxial-rotor helicopter designed by Newby O. Brantly and constructed by the Pennsylvania Elastic Company, Brantly's employer. Design and development In 1946, Brantly started flight testing the B-1 prototype (NX69125), which used a 150 hp Franklin O-335 The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of six-cylinder, horizontally-opposed layout and displaced . The power output of later variants was . ... engine in the fabric fuselage and two three-bladed rotors that rotated at 320 rpm and were fitted coaxially. The collective, cyclic, and differential controls were enclosed in the rotor hubs and ran in an oil-bath. Each rotor blade weighed 5.5 kilos. It also had a fixed wheel undercarriage with a tailwheel under the tailfin. Unfortunately, the design was too heavy and complex and was abandoned. Specifications References External links Brantly ...

Brantly International
Brantly International Inc. is an American helicopter company with its engineering and administrative offices based Coppell, Texas, United States. Manufacturing of Brantly-designed helicopters is now carried out by Qingdao Haili Helicopters of China. History Brantly Helicopter The company started out 1945 as Brantly Helicopter Corporation in Philadelphia, Pennsylvania, founded by Newby O. Brantly. Brantly was so impressed with the Sikorsky VS-300 that he decided to design his own helicopter. In 1946 his first helicopter, the Brantly B-1 with coaxial rotors made its first flight. The B-1 was not put into production. Using lessons learned from the B-1, he decided to build a two-seater with a simple rotor design. This helicopter, the Brantly B-2, made its first flight 1953. In 1957 the company moved to Frederick, Oklahoma, where the B-2 was certified in 1959. He later designed the Brantly 305, a five-seater which made its first flight 1964. It was certified by the FAA in 1965, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1946 In Aviation
This is a list of aviation-related events from 1946: Events * The American Section of the International League of Aviators resurrects the National Trophy, a Harmon Trophy awarded from 1926 to 1938 to the outstanding aviator of the year in each of the 21 member countries of the now-defunct League. It will be awarded until 1949 amid much controversy, with the awards going largely unrecognized. * The Electric Boat Company purchases Canadair from the Government of Canada, an important step toward the 1952 founding of General Dynamics Corporation. * The ''Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile'' (BEA), or Bureau of Investigation and Analysis for Civil Aviation Safety, is formed as the Government of France, French government agency responsible for investigating aviation accidents and incidents and making safety recommendations based on what is learned from those investigations. * The Nicaraguan airline LANICA begins flight operations.

Franklin O-335
The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of Flat-six engine, six-cylinder, horizontally-opposed layout and Engine displacement, displaced . The power output of later variants was . Design and development These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the Franklin 2A4, 2A4 and Franklin 4A4, 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin's United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. In 1947 this engine was modified into a water-cooled version by the Preston Tucker, Tucker Car Corporation for use in the 1948 Tucker Sedan. Tucker liked the engine so much that he purchased the Aircooled Motors/Franklin Engine Company, and it remained under the ownership of the ...

1940s United States Civil Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Coaxial Rotor Helicopters
In geometry, coaxial means that several three- dimensional linear or planar forms share a common axis. The two-dimensional analog is ''concentric''. Common examples: A coaxial cable is a three-dimensional linear structure. It has a wire conductor Conductor or conduction may refer to: Music * Conductor (music), a person who leads a musical ensemble, such as an orchestra. * ''Conductor'' (album), an album by indie rock band The Comas * Conduction, a type of structured free improvisation ... in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. Coaxial rotors are a three-dimensional planar structure: a pair of helicopter rotors (win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft First Flown In 1946
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air b ...
