Paper plane, paper aeroplane (uk), paper airplane (us), paper glider, paper dart or dart is a toy aircraft, usually a glider made out of folded paper or paperboard. Origin of folded paper gliders is generally considered to be of ancient china, although there is equal evidence that the refinement and development of folded gliders took place in equal measure in japan. Certainly, manufacture of paper on a widespread scale took place in china 500 bce, and origami and paper folding became popular within a century of this period, approximately 460-390 bce.
Research about paper airplanes
It is impossible to ascertain where and in what form the first paper aircraft were constructed, or even the first paper plane's over a thousand years after this, paper aircraft were the dominant man-made heavier-than-air craft whose principles could be readily appreciated, though thanks to their high drag coefficients, not of an exceptional performance when gliding over long distances. The pioneers of powered flight have all studied paper model aircraft in order to design larger machines. Da vinci wrote of the building of a model plane out of parchment, and of testing some of his early ornithopter, an aircraft that flies by flapping wings, and parachute designs using paper models. Thereafter, sir george cayley explored the performance of paper gliders in the late 19th century. Charles langley, and alberto santos-dumont often tested ideas with paper as well as balsa models to confirm (in scale) their theories before putting them into most significant use of paper models in aircraft designs were by the wright brothers between 1899 and 1903, the date of the first powered flight from kill devil hills, by the wright flyer. By observing the forces produced by flexing the heavy paper models within the wind tunnel, the wrights determined that control through flight surfaces by warping would be most effective, and in action identical to the later hinged aileron and elevator surfaces used today. Their paper models were very important in the process of moving on to progressively larger models, kites, gliders and ultimately on to the powered flyer (in conjunction with the development of lightweight petrol engines). In this way, the paper model plane remains a very important key in the graduation from model to manned heavier-than-air time, many other designers have improved and developed the paper model, while using it as a fundamentally useful tool in aircraft design. One of the earliest known applied (as in compound structures and many other aerodynamic refinements) modern paper plane was in 1909.
Construction of a paper airplane, by ludwig prandtl at the 1924 banquet of the international union of theoretical and applied mechanics, was dismissed as an artless exercise by theodore von kármán:[1]. He started to explain; in the course of it he picked up a paper menu and fashioned a small model airplane, without thinking where he was. It landed on the shirtfront of the french minister of education, much to the embarrassment of my sister and others at the 1930 jack northrop (co-founder of lockheed corporation) used paper planes as test models for larger aircraft. In germany, during the great depression, designers at heinkel and junkers used paper models in order to establish basic performance and structural forms in important projects, such as the heinkel 111 and junkers 88 tactical bomber recent times, paper model aircraft have gained great sophistication, and very high flight performance far removed from their origami origins, yet even origami aircraft have gained many new and exciting designs over the years, and gained much in terms of flight have been many design improvements, including velocity, lift, propulsion,[2] style and fashion, over subsequent ed paper gliders have experienced three forms of development in the period 1930–1988:High flight g development of folded/origami gliders over the same period has seen similar sophistication, including the addition of the following construction sed fold-count, sometimes of an intricate it kirigami (cutting of paper) as a component of ements for additional ballast to ensure flight logical logy responsible[citation needed] for the proliferation of advanced paper plane construction:Inexpensive cad software for 2d part read manufacture, and inexpensive nature of acetal air-annealed glues, e. Bostick nsive ink and laser computer printers, for accurate aircraft part advent of the internet, and widespread information al ed to balsa wood, another material commonly used to fabricate model planes, paper's density is higher; consequentially, conventional origami paper gliders (see above) suffer from higher drag, as well as imperfectly aerodynamic wing r, unlike balsa gliders, paper gliders have a far higher strength-to-thickness ratio – a sheet of office-quality 80 g/sq m photocopier/laser printer paper, for example, has approximate in-scale strength of aircraft-grade aluminium sheet metal, while card stock approximates the properties of steel at the scale of paper model ions in advanced paper aircraft fied origami paper aircraft have very poor glide ratios, often not better than 7. Modification of origami paper gliders can lead to marked improvements in flight performance, at the cost of weight and often with the inclusion of aerodynamic and/or structural compromises. Ranges of flight increased from the typical 10+ meters to 85+ meters, depending on energy input into the gliders on present, the work of the two professors remains the last serious research work on improving the flight performance of paper model gliders. In addition, fuselages are either balsa-paper or paper laminates, prone to warping or breakage over a very short time. Improvement in performance is possible through modelling three-dimensional fuselages which encourage laminar flow, and in internally braced wings which can then have high-lift aerofoil profiles, such as the clark y or naca 4 or 6 series, for high japan in the late 1960s, professor yasuaki ninomiya designed an advanced type of paper aircraft, which were published in two books, jet age jamboree (1966) and airborne all-stars (1967).
Designs from these books were later sold as the 'white wings' series of paper glider packs from the 1970s to the present wings are a stark departure from conventional paper aircraft, in that their fuselages and wings are paper templates cut and glued together. Construction of the models is of kent paper, a grade of cartridge paper sold in early models were explicitly hand drawn, but by the 1980s these had their parts drafted with the use of cad below is the n-424 glider from jet age jamboree (1966) the glider fuselage is constructed from several laminations of paper glued together. Ninomiya's designs also included, for the first time in any paper model, working propellers driven by airflow, in particular for his profile scale models of the cessna skymaster and piaggio p. Noteworthy as well was the careful design of gliders so that they could fly without ballast – his f-4 phantom ii model is able to be flown immediately without recourse to paperclips high performance gliders have fuselages that are kept rigid by the use of a balsa fuselage profile bonded to the paper components. The paper used is quite heavy, approximately twice the weight of standard drawing cartridge paper, but lighter than lightweight cardboard. Book was very successful, leading to additional volumes, paper pilot 2 (1988), paper pilot 3 (1991), 12 planes for the paper pilot (1993) and ju-52, a stand-alone book featuring a scale ished models include an airbus a320 scale model much like the ju-52, seen on the tekkies youth program in books featured patterns of parts printed on lightweight cardstock, to give the aircraft good flight penetration performance for long distance and interest in the gliders, and their publishing success, allowed some of the development to be broadcast on south african television during 1988 on the first book's release, and again 1993, to coincide with a national paper aeroplane competition tied to paper pilot 3's namic design of the gliders was achieved making use of an optimised small wind tunnel - the flat-glider britten norman trislander was filmed in this facility, with weight balances being used to demonstrate the optimisation of design of parts of the gliders was achieved using autodesk autocad r12, then the most advanced version of this cad software, and one of the first publicly available paper model aeroplanes designed using this uction of the gliders closely parallels that used in the white wings series of gliders of dr. Their design, like the white wings gliders, is very sensitive to trim, and in fact have the capacity to make indoor flights in confined spaces under average in initial editions are equipped with catapult hook patterns, and demonstrate an ability to fly the length of a rugby pitch when so editions and gliders were equipped with a bungee hook, the construction of which was included in paper pilot 3 and 12 planes for the paper bungee system publish parallels, at a smaller scale, the practice used in radio controlled and full-size sailplane launches, at a fraction of the cost and complexity. To date, this is the only known example of such a launch system applied to a paper model aeroplane type published in book performance on bungee is very good - one glider in particular, a scale model u-2 (in the last book of the series) had demonstrated flight performance in excess of 120 meters, on bungee hook launch. Mathews is the papercopter, a model helicopter whose 'wing' is a trimmable annular ring which, using rotational aerodynamics to provide good forward flight performance without need for a tail rotor.
A model helicopter 'body' is suspended beneath the ring, and uses airflow to stabilise itself in the direction of flight, much like a weather papercopter design permits flights of approximately 10–14 meters on helicopters (autogyros). World's first known published paper autogyro (engineless helicopter) by richard k neu appeared in "the great international paper airplane book" published in 1967. This basic design has been published several times and is widely world's first known published forward-gliding paper autogyro with forward-pointing body lifted by spinning blades was built by james zongker. It appears on page 53 of "the paper airplane book: the official book of the second great international paper airplane contest" published in 1985 by science magazine. Its twin contra-rotating blades automatically spin on paper axles upon launch to provide noted above (see entry, paper pilot), e. While not an autogyro per se, this paper model aircraft class falls within the general design of a paper model helicopter, and does possess a rotational flight element producing lift during forward flight. Papercopters, as professor mathews labeled them, are unique among paper model rotorcraft in having a range and velocity far in excess of all other classes, able to fly quite quickly, and with a range of between 10–15 m. Have been many attempts over the years to break the barriers of throwing a paper plane for the longest time aloft. Ken blackburn held this guinness world record for 13 years (1983–1996) and had regained the record on october 1998 by keeping his paper plane aloft for 27.
Contest-winning paper aircraft are a class of model plane, and so do not experience aerodynamic forces differently from other types of flying model. However, their construction material produces a number of dissimilar effects on flight performance in comparison with aircraft built from different general, there are four aerodynamic forces that act on the paper aircraft while it is in flight:Thrust, which keeps the plane moving forward;. Which counteracts lift and pulls the plane downward; drag, which counteracts thrust and reduces the plane's forward ther, the aerodynamic forces co-interact, creating turbulence that amplifies small changes in the surface of the paper aircraft. Modifications can be made to most paper airplanes by bending, curving or making small cuts in the trailing edges of wings and in the airplane's tail, if it has article: roll, pitch, and most common adjustments, modelled after glider aircraft, are ailerons, elevators, and reynolds number range of the paper model aircraft is reasonably wide:2,000–12,000 for origami aircraft. As noted above the mass: density ratio of paper prevents performance from reaching those of balsa models in terms of expressions of power to weight, but for models with wingspans of between 250 mm and 1,200 mm, the critical re is very similar to balsa model gliders of similar models typically have a wing aspect ratio that is very high (model sailplanes) or very low (the classic paper dart), and therefore are in almost all cases flying at velocities far below their wing planform and aerofoil critical re, where flow would break down from laminar to origami paper darts tend to be flying within turbulent air in any case, and as such, are important to research into turbulent flow as are low-re lifting surfaces found in nature such as leaves of trees and plants as well as the wings of performance profile and scale models do approach their wing section's critical re in flight, which is a noteworthy achievement in terms of paper model design. Performance is derived of the fact that wings of these gliders are in fact performing as well as it is possible for them to perform, given their material ments in different material finishes in recent years have revealed some interesting relationships in re and paper models. Performance of origami and compound origami structures improves markedly with the introduction of smooth paper, though this is also aided by the paper's higher mass and consequently better marginal performance and scale types generally do not benefit from heavier, shinier surfaces. Performance profile-fuselage types do experience somewhat improved performance if shiny, slippery paper is used in construction, but although there is a velocity improvement, this is offset very often by a poorer l/d ratio. Scale types have experience negative performance at the addition of heavy shiny papers in their profile sections in models vary, depending on type:Origami : göttingen flat-plate, or jedelsky-form for folded leading nd origami: identical with origami, though often with sealed edges – 45% improvement in e performance: göttingen curved-plate, with profile similar to göttingen performance: göttingen 801 or any other wing models: this varies on model type (see below).
Wwii monoplanes will often have very scale-like sections, though with increased trailing edge droop to improve camber in comparison with scale rly, size, airspeed and mass will have very big impacts on choice of aerofoil, though this is a universal consideration in model plane design, no matter the former guinness world record holder tim richardson disagrees with the decision to put a 'tail' on the paper plane. His explanation of paper plane aerodynamics on his website mentions that the tail is not needed. Note: paper planes do not need a tail primarily because they typically have a large, thin fuselage, which acts to prevent yaw, and wings along the entire length, which prevents pitch. Edmond hui invented a stealth bomber-like paper plane called the paperang in 1977,[7] based on hang glider aerodynamics. It was the subject of a book, "amazing paper airplanes" in 1987, and a number of newspaper articles in 1992. It is ineligible for most paper plane competitions due to the use of a staple, but it has extremely high gliding performance exceeding glide ratios of 12 to 1 with good 1975, origami artist michael lafosse designed a pure origami (one sheet; no cutting, glue or staples... Its aerodynamic form mimics some hang glider and supersonic airfoils, its invention evolved from exploring the beauty of folded paper first. Its glide ratio and stability are on a par with many of the best paper wing constructions that use glue, tape or staples. Martin's gh it is a common view that light paper planes go farther than heavy ones, this is considered to be untrue by blackburn.
Blackburn's record-breaking 20-year-old paper plane[8] was based on his belief that the best planes had short wings and are "heavy" at the point of the launch phase in which the thrower throws the paper plane into the air, and at the same time longer wings and a "lighter" weight would allow the paper plane to have better flight times but this cannot be thrown hard with much pressure into the air as a "heavy" weighted launch phase. According to blackburn, "for maximum height and for a good transition to gliding flight, the throw must be within 10 degrees of vertical" — which shows that a speed of at least 60 miles per hour (97 kilometres per hour) is the amount needed to throw the paper plane the folding there are still gaps between different layers of folded paper (tearoff edge). The other uses a swept wing or axial folding to produce something like a fuselage extending out of leading edge of the example of an asymmetrical custom paper airplane, which exhibits large torque due to unbalanced forces on the wings. The flight path assumes a somewhat parabolic shape, before descending in a rapid counter-clockwise spiral, as viewed from is possible to create freestyle versions of paper aircraft, which often exhibit an unusual flight path compared to more traditional paper darts, jets and gliders. Walkalong gliding involves the continuous propulsion of paper airplane designs (such as the tumblewing, follow foil[9] and paper airplane surfer[10]) by soaring flight on the edge of a sheet of may one day be a paper plane launched from space.
