Bensen B-9
The Bensen B-9 Little Zipster was a small helicopter developed by Igor Bensen in the United States in the 1950s and marketed for home building. Similar in general configuration to Bensen's previous rotor kite and autogyro designs, it consisted of an open aluminum framework but substituted the autorotating main rotor for a coaxial 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 conduc ..., counter-rotating system of two, two-bladed rotors. A large tailfin provided directional stability, and the aircraft was controlled by a handlebar system extending over the pilot's head to the rotor hub.

Bensen Aircraft
The Bensen Aircraft Corporation was established by Dr. Igor Bensen at Raleigh-Durham International Airport in North Carolina in 1952 to develop and market a variety of helicopters and autogyros of Bensen's own design.

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Igor Bensen
Igor Vasilevich Bensen (russian: И́горь Васи́льевич Бенсен; April 1, 1917 – February 10, 2000) was a Russian-American engineer. He founded Bensen Aircraft, a US company which produced a successful line of gyrogliders (rotor kites) and autogyros. Early life and education He was born in Rostov-on-Don, Russia, and eventually reached the United States in 1937. He began studies at age 17 while in Belgium, won a scholarship to study in the US three years later. He received a Bachelor of Science degree in mechanical engineering from Stevens Institute of Technology in Hoboken, New Jersey in 1940, later becoming a Registered Professional Engineer. Career Bensen flew his first towed gyroglider in 1954. He founded the Popular Rotorcraft Association (PRA) in 1962, a non-profit interest group for owners and homebuilders of autogyros and helicopters, based in Mentone, Indiana. He was the group's president from 1962 to 1971. Honors and awards He received an hon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autorotation (helicopter)
Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. Bensen, Igor.How they fly – Bensen explains all" ''Gyrocopters UK''. Accessed: 10 April 2014. Quote: "air.. (is) deflected downward"Charnov, Bruce HCierva, Pitcairn and the Legacy of Rotary-Wing Flight ''Hofstra University''. Accessed: 22 November 2011. The term ''autorotation'' dates to a period of early helicopter development between 1915 and 1920, and refers to the rotors turning without the engine."Autorotation", ''Dictionary.com Unabridged (v 1.1)''.

Coaxial Rotor
Coaxial rotors or coax rotors are a pair of helicopter rotors mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau. History The idea of coaxial rotors originates with Mikhail Lomonosov. He had developed a small helicopter model with coaxial rotors in July 1754 and demonstrated it to the Russian Academy of Sciences. In 1859, the British Patent Office awarded the first helicopter patent to Henry Bright for his coaxial design. From this point, coaxial helicopters developed into fully operational machines as we know them today. Two pioneering helicopters, the Corradino D'Ascanio-built "D'AT3" of 1930, and the generally more successful French mid-1930s ''Gyroplane Laboratoire'', both used coaxial rotor systems for flight. Design considerations Having two coaxial sets of rotors provides s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury Marine
Mercury Marine is a marine engine division of Brunswick Corporation headquartered in Fond du Lac, Wisconsin. The main product line is outboard motors. It also produces the MerCruiser line of sterndrives and inboard motors. Some manufacturing is in Fond du Lac, while 40-60 HP motors are made in China. Smaller motors are Tohatsus that have been rebadged. History Founding The Kiekhaefer Mercury company began in 1939 when engineer Carl Kiekhaefer purchased a small outboard motor company in Cedarburg, Wisconsin. Kiekhaefer's original intention for the Kiekhaefer Corporation was to make magnetic separators for the dairy industry. The purchase included 300 defective outboard motors. Kiekhaefer and a small staff of employees rebuilt the motors and sold them to Montgomery Ward, a mail-order company. The motors were much improved, so the buyer purchased more. Kiekhaefer designed motors that withstood the elements better than his competition and called the motor Mercury (taking advanta ...

1950s United States Sport Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support. Severus marches to Mesopotamia to battle the Parthians. * The Roman province of Syria is divided and the role of Antioch is diminished. The Romans annexed the Syrian cities of Edessa and Nisibis.
