Charles Richards (NASA Engineer)
Charles Richard was a design engineer, who designed the collapsible four-tube Rogallo wing used in the experimental NASA Paresev glider. The wing configuration he created was used for manned hung-pilot kite-gliders and was to be found copied only with slight ornamental variation in a decade of hang gliders. Richards was of the Flight Research Center's Vehicle and System Dynamics Branch. The four-beamed wing folded from the noseplate; one of the beams was the spreader beam that kept the flexible-wing's sweep. Those in the following decade copying the Charles Richard wing configuration expanded kiting, hang gliding, ultralight, and trike flight. Timeline * 1961 December : Charles Richard is given a directive from NASA's Paul Bikle to build quickly a cheap kite glider that could be used to give pilots practice in flying in free flight using simple weight-shifting that would change the attitude of the wing relative to the hung position of the pilot and payload. * 1962 February 12 : ...

NASA Paresev
The NASA Paresev ("Paraglider Research Vehicle") was an experimental NASA glider aircraft based upon the kite-parachute studies by NASA engineer Francis Rogallo. Between 1961 and 1965 the ability of the Rogallo wing (also called "Parawing") to descend a payload such as the Project Gemini, Gemini space capsule safely from high altitude to ground was studied.Aviation News article
The Paresev was a test vehicle used to learn how to control this parachute-wing for a safe landing at a normal airfield. Publicity on the Paresev and the Ryan XV-8, Ryan XV-8 "Flying Jeep" aircraft inspired hobbyists to adapt Rogallo's flexible wing airfoil onto elementary History of hang gliding, hang gliders leading to the most successful hang glider configuration in history.

Wing
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning has ...

Hang Glider
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to soar for hours, gain thousands of feet of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of being instructed is highly recommended and indeed a ...

Kite
A kite is a tethered heavier than air flight, heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create Lift (force), lift and Drag (physics), drag forces. A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. Some kite designs don’t need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite. The name is derived from kite (bird), kite, the hovering bird of prey. The Lift (force), lift that sustains the kite in flight is generated when air moves around the kite's surface, producing low pressure above and high pressure below the wings. The interaction with the wind also generates horizontal Drag (physics), drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of one or more of the rope, lines or tethers to which t ...

Ultralight
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and conventional three-axis control aircraft with ailerons, elevator and rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is installed. The definition means that the aircraft has a slow landing speed and short ...

Ultralight Trike
An ultralight trike is a type of powered hang glider where flight control is by weight-shift. These aircraft have a fabric flex-wing from which is suspended a tricycle fuselage pod driven by a pusher propeller. The pod accommodates either a solo pilot, or a pilot and a single passenger. Trikes grant affordable, accessible, and exciting flying, and have been popular since the 1980s. Trikes are classified as microlights in Europe, and as light-sport aircraft in the United States. The aircraft are also known by other names, including 2-axis microlights, flex-wing trikes, microlight trikes, deltatrikes or motorized deltaplanes. In the United States, they are formally recognized by the Federal Aviation Administration (FAA) as weight-shift-control aircraft. History ] The history of the trike is traced back to the invention of Francis Rogallo's flexible wing and subsequent development by the Paresev engineering team's innovations and then others. On 1948, engineer Francis ...

Paul Bikle
Paul F. Bikle (5 June 1916 – 19 January 1991) was director of the U.S. National Aeronautics and Space Administration (NASA) Dryden Flight Research Facility from 1959 until 1971, and author of more than 40 technical publications. He was associated with major aeronautical research programs including the hypersonic X-15 rocket plane, and was a world record-setting glider pilot. Civilian career Before graduating from the University of Detroit in 1939 with a BSc. degree in aeronautical engineering, Bikle's activity in the student chapter of the Institute of the Aeronautical Sciences (IAS), and the school gliding and flying clubs, led to flight instruction and a pilot's license from the C.A.A., the predecessor to the FAA. He later became a fellow in the American Institute of Aeronautics and Astronautics, the successor to the IAS. Mr. Bikle worked for Taylorcraft Aircraft in Ohio before beginning his government service career. Air Force career His career with the U.S. Air Force bega ...

Stardust (spacecraft)
''Stardust'' was a 385-kilogram robotic space probe launched by NASA on 7 February 1999. Its primary mission was to collect dust samples from the coma of comet Wild 2, as well as samples of cosmic dust, and return them to Earth for analysis. It was the first sample return mission of its kind. En route to comet Wild 2, it also flew by and studied the asteroid 5535 Annefrank. The primary mission was successfully completed on 15 January 2006 when the sample return capsule returned to Earth. A mission extension, codenamed ''NExT'', culminated in February 2011 with ''Stardust'' intercepting comet Tempel 1, a small Solar System body previously visited by '' Deep Impact'' in 2005. ''Stardust'' ceased operations in March 2011. On 14 August 2014, scientists announced the identification of possible interstellar dust particles from the ''Stardust'' capsule returned to Earth in 2006. Mission background History Beginning in the 1980s, scientists began seeking a dedicated mis ...

NASA People
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management for ...
