Private Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bensen B-10
The Bensen B-10 Propcopter was an unconventional VTOL aircraft developed by Igor Bensen in the United States in the late 1950s. The pilot sat astride a beam that had an engine mounted at either end of it, each driving a rotor to provide lift. Each of these rotors was surrounded by a system of four pivotable vanes to direct its downwash In aeronautics, downwash is the change in direction of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the process of producing lift.Crane, Dale: ''Dictionary of Aeronautical Terms, thir ..., and linked to a control stick for the pilot, this provided control of the craft. Only a single prototype (registered ''N56U'') was built.

Gyroglider
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.

Gyrocopter
An autogyro (from Ancient Greek, Greek and , "self-turning"), also known as a ''gyroplane'', is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift (force), lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down. The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. He first flew one on 9 January 1923, at Cuatro Vientos Airport, Cuatro Vientos Airfield in Madrid. The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. Cierva's autogyro is considered the predecessor of the modern helicopter. The success of the autogyro garnered the interest of industrialists and under license from Cierva in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bensen X-25
The Bensen B-8 is a small, single-seat autogyro developed in the United States in the 1950s. Although the original manufacturer stopped production in 1987, plans for homebuilders are still available as of 2019. Its design was a refinement of the Bensen B-7, and like that aircraft, the B-8 was initially built as an unpowered rotor-kite. It first flew in this form in 1955, and on 6 December a powered version, designated B-8M (M for motorised) first flew. The design proved to be extremely popular and long-lasting, with thousands of sets of plans sold over the next thirty years. Design and development The B-8's design is extremely minimalist, with not much more to the aircraft than a pilot's seat, a single tailfin, a rotor, and (in powered versions) the powerplant. In May 1968 a B-8 and B-8M were studied by the USAF under the Discretionary Descent Vehicle (DDV) program as the X-25B and X-25A respectively. In this scheme, it was proposed to integrate combat aircraft ejection seats ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

Bensen B-12
The Bensen B-12, variously dubbed the Sky-Way or Sky-Mat was an unconventional multirotor developed by Igor Bensen in the United States in the late 1950s. Extremely unorthodox, the design sprang from Bensen's thinking about the engine redundancy necessary to ensure the safe operation of small, personal rotorcraft operating at low altitudes and slow speeds. The result was a broad aluminum framework supporting an array of ten engines and rotors that Bensen likened to a "magic carpet A magic carpet, also called a flying carpet, is a legendary carpet and common trope in fantasy fiction. It is typically used as a form of transportation and can quickly or instantaneously carry its users to their destination. In literature One o ...".Bensen 1992, 110 The design was later refined to include eight rotors, each driven by two engines for a total of sixteen.

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.
