Bensen B-5
The Bensen B-5 was a small rotor kite developed by Igor Bensen in the United States and offered and marketed for home building in 1954. Dubbed the "Gyro-Glider", it was the first of several such designs that would be sold by Bensen Aircraft Corporation over the following decades. The B-5 was built around a cruciform frame of aluminum tube. Landing wheels were fitted to three points of this cross, and a mast was fitted above its centre to support the rotor hub. The fourth arm of the cross provided a mounting for a large, plywood fin and rudder, reminiscent of that of the Raoul Hafner's Rotachute that had shaped Bensen's thinking about rotor kite design. The aircraft was intended to be towed behind a car, and could be built at home from easily obtained materials in about three to four weeks. The B-5 was also the model converted to the Bensen Mid-Jet The Bensen Mid-Jet (a pun on "Midget jet") was a small helicopter developed by Igor Bensen in the United States in the early 195 ...

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] |
Rotor Kite
A rotor kite or gyrokite is an unpowered, rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly. Unlike a helicopter, gyrokites and rotor kites do not have an engine powering their rotors, but while an autogyro has an engine providing forward thrust that keeps the rotor turning, a rotor kite has no engine at all, and relies on either being carried aloft and dropped from another aircraft, or by being towed into the air behind a car or boat or by use of ambient winds for the kiting. As of 2009, no country in the world requires a license to pilot such a craft. History * Thomas Ansboro of Glasgow, Scotland patented an autorotating-winged rotor kite in 1891. * Walter Van Wie filed a patent for a ''Revolving Kite'' in 1909 claiming "certain new and useful Improvements" in revolving kites" * 1933: Filed: July 11, 1933US2074327by De Courcy and Schwarz for ''Kite''. * 1936: Filed: Aug 1, 1936US2181477by Carl B. ...

Raoul Hafner
Raoul Hafner, (1905–1980) FEng, FRAes, was an Austrian-born British helicopter pioneer and engineer. He made a distinctive contribution to the British aerospace industry, particularly in the development of helicopters. Life Born in 1905, he was educated in Vienna, first at the university and then at technical college where he became interested in rotary-wing concept as a means of making aircraft land more slowly and safely. He obtained a post with the Austrian Air Traffic Company, but his heart was in helicopter design. He gave up his job to concentrate on helicopters, designing and building the Hafner Nagler R.I Revoplane in 1929 in collaboration with Bruno Nagler, then the similar Hafner Nagler R.II Revoplane in 1931.''Bristol Sycamore'' Heli Archive [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotachute
The Hafner H.8 Rotachute was a British 1940s experimental one-man rotor kite designed by Raoul Hafner. Background The Rotachute was the eventual development of a concept devised by Raoul Hafner, an Austrian engineer who specialised in rotary wing design, and who had moved to the UK in 1933 to continue his research and development work. In 1940, he proposed the use of a single-place strap-on rotor kite in place of a conventional parachute, to deliver a soldier accurately to a battlefield. The proposal was made to the Air Ministry in the light of a shortage of silk for parachute manufacture. Hafner was briefly interned as an alien, but was released to pursue the feasibility of the idea at the Central Landing Establishment (CLE) located at RAF Ringway. In October 1940, work began on design and construction of rotor systems and scale models of rotor kites. The first models were made of wood and fabric, ballasted to represent a pilot, and had a rotor span of about 3 ft (0.91 m). ...

Bensen Mid-Jet
The Bensen Mid-Jet (a pun on "Midget jet") was a small helicopter developed by Igor Bensen in the United States in the early 1950s in the hope of attracting the interest of the United States Navy. It was a single-seat, open framework machine based on the B-5 rotor kite with small, gasoline- or fuel oil-burning ramjets mounted as tipjet A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework. Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, thus not re ...s on the rotor blades. Tests carried out in 1954 showed it to be able to lift four times its own weight and cruise at 75 mph (120 km/h).

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.
