Flight Dynamics Flightsail VII
The Flight Dynamics Flightsail VII was a recreational aircraft marketed in the United States in the 1970s for homebuilding by Flight Dynamics, Inc., most unusual both in its design and its method of construction. The Flightsail VII was intended to be built in three stages, with each stage representing a flyable aircraft of increasing complexity, capability, and cost. It was hoped that this approach would appeal to homebuilders by minimizing the amount of time and money required to take the aircraft to a point where it could be flown. The core of the Flightsail VII was a pod-and-boom style fuselage, the pod component of which was in the form of a thick airfoil with integral pontoons at its bottom to aid stability in water. This fuselage could be fitted with flexible, hang-glider-like wings and be flown by having it towed aloft by a speedboat. It could either be left as such and operated in this form (known as a Seasprite) or serve as "Stage I" for the Flightsail VII. In "Stage II", ...

Flight Dynamics Flightsail
The Purcell Flightsail or Flight Dynamics Flightsail is an experimental towed glider by Thomas H. Purcell, Jr. He sold plans in several publications for the tow-launched hung-mass controllable kite-glider. He flew first off water in late 1961 and then arranged things for off-land and landing on land. His efforts would find similarity echo later in early 1963 by the SkiPlane of Mike Burns. Development The Flightsail is a single seat open cockpit parasol-winged glider with tricycle landing gear. The fuselage is constructed of a triangular pyramid-shaped or tetrahedral truss; the pilot was positioned in front of the triangle-control frame. The framed flexible wing resembles a hang-glider arrangement as used on the kited gliders of Paresev program and by Ryan Aeronautical Company. The glider used weight-shift pendulum control using a stick with cables that shifts the cg of the frame relative to the wing pivoting above it. The wing is constructed with a 50-degree sweep based on NAS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skycraft Scout
The Skycraft Scout is an Australian designed and built single-seat, tail dragger, microlight airplane, used primarily for recreational aviation. Design and development In July 1972 a Sydney boat builder named Ronald Gilbert Wheeler made the first flight of a minimum aircraft which he'd designed and built himself, and which he put into series production soon thereafter. At the time Ron was building catamarans in Sydney's southern suburbs. Having already develope'Tweetie' a successful hang glider, Wheeler simply modified the design of the glider to have the pilot seated instead of hanging below the wings, and of course to accommodate an engine. Marketed as the Skycraft Scout, this was the world's first commercially produced ultra light – rigid wing rather than a Rogallo – and spawned a new Australian industry. Ron had no experience in aircraft design and claims to have started the project on a whim in his spare time. Using sources referenced from the library at Sydney Technic ...

Waco CG-4
Waco ( ) is the county seat of McLennan County, Texas, United States. It is situated along the Brazos River and I-35, halfway between Dallas and Austin. The city had a 2020 population of 138,486, making it the 22nd-most populous city in the state. The 2021 U.S. Census population estimate for the city was 139,594. The Waco metropolitan statistical area consists of McLennan and Falls counties, which had a 2010 population of 234,906. Falls County was added to the Waco MSA in 2013. The 2021 U.S. census population estimate for the Waco metropolitan area was 280,428. History 1824–1865 Indigenous peoples occupied areas along the river for thousands of years. In historic times, the area of present-day Waco was occupied by the Wichita Indian tribe known as the "Waco" (Spanish: ''Hueco'' or ''Huaco''). In 1824, Thomas M. Duke was sent to explore the area after violence erupted between the Waco people and the European settlers. His report to Stephen F. Austin, described the Waco v ...

Rogallo Wing
The Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogallo Wing" and flexible wing. NASA considered Rogallo's flexible wing as an alternative recovery system for the Mercury and Gemini space capsules, and for possible use in other spacecraft landings, but the idea was dropped from Gemini in 1964 in favor of conventional parachutes. History Rogallo had been interested in the flexible wing since 1945. He and his wife built and flew kites as a hobby. They could not find official backing for the wing, including at Rogallo's employer National Advisory Committee for Aeronautics (NACA), so they carried out experiments in their own time. By the end of 1948 they had two working designs using a flexible wing — a kite they called "Flexi-Kite" and a gliding parachute they later referred to as a "paraglider". Rogallo and hi ...

1970s United States Sport Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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.

Flying Boats
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
