Construction of the models is of Kent paper, a grade of cartridge paper sold in Japan. The early models were explicitly hand drawn, but by the s these had their parts drafted with the use of CAD software. Seen below is the N glider from Jet Age Jamboree The glider fuselage is constructed from several laminations of paper glued together. The wings are of two laminations, and the tailplane and tailfin of a single lamination. 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 etc.
The 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.
Original White Wings were entirely paper, requiring patience and skill. Later however, balsa-wood fuselages were used, and White Wings were sold "pre-cut", making construction easier. In , Professor E. Mathews, lecturer in Thermodynamics at the University of the Witwatersrand , South Africa published his first compendium of high-performance model aircraft. This book was Paper Pilot Struik, This book was very successful, leading to additional volumes, Paper Pilot 2 , Paper Pilot 3 , 12 Planes for the Paper Pilot and Ju , a stand-alone book featuring a scale model.
Unpublished models include an Airbus A scale model much like the Ju, seen on the Tekkies youth program in The books featured patterns of parts printed on lightweight cardstock, to give the aircraft good flight penetration performance for long distance flight. Public interest in the gliders, and their publishing success, allowed some of the development to be broadcast on South African television during on the first book's release, and again , to coincide with a national paper aeroplane competition tied to Paper Pilot 3's release.
Aerodynamic 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 flight. The 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 technology. Construction of the gliders closely parallels that used in the White Wings series of gliders of Dr.
Ninomiya for flat gliders. Later gliders with three-dimensional fuselages use a lightweight construction optimised for flight performance. Innovations include functional wheeled undercarriage which does not contribute to the drag budget while permitting good landings. Paper pilot gliders make use a curved-plate aerofoil shape for best performance. 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 conditions.
Most in initial editions are equipped with catapult hook patterns, and demonstrate an ability to fly the length of a Rugby pitch when so launched.
Later 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 Pilot. The 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 form.

Flight 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 meters, on bungee hook launch. A unique development of Prof. 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 vane.

Its wings fly in a circle around a central ballast shaft as it descends vertically. This basic design has been published several times and is widely known. The world's first known published forward-gliding paper autogyro with forward-pointing body lifted by spinning blades was built by James Zongker. Its twin contra-rotating blades automatically spin on paper axles upon launch to provide lift.
As noted above see entry, Paper Pilot , E.
Paper plane - Wikipedia
Mathews developed a flight-stable paper model helicopter. This has a ring wing, and flaps for adjusting for flight for stability, positioned on the inboard edge of the ring. 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. The longest flight time is For every goal there is a typical plane and sometimes a world record.
There 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 and had regained the record on October by keeping his paper plane aloft for This was confirmed by Guinness officials and a CNN report. As of [update] , Takuo Toda holds the world record for the longest time in air 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 materials. In general, there are four aerodynamic forces that act on the paper aircraft while it is in flight:. Altogether, 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 one. The most common adjustments, modelled after glider aircraft, are ailerons , elevators , and rudders.
The Reynolds number range of the paper model aircraft is reasonably wide:. These ranges are indicative. Paper 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 turbulent.
Most 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 insects. High 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 limitations. Experiments 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 penetration.
More marginal performance and scale types generally do not benefit from heavier, shinier surfaces. Scale types have experience negative performance at the addition of heavy shiny papers in their construction. Camber of profiles varies, too. In general, the lower the Re, the greater the camber.
Origami types will have 'ludicrous' or very high cambers in comparison with more marginally performing scale types, whose escalating masses demand higher flying speeds and so lower induced drag from high camber, though this will vary depending on type being modelled. In the case of scale performance and scale models, the modellers intent will define the type of aerofoil section chosen.
WWI biplanes, if designed for flight performance, will often have curved-plate aerofoils, as these produce a highly cambered surfaces and Coefficient of Lift Cl for low gliding airspeeds. WWII monoplanes will often have very scale-like sections, though with increased trailing edge droop to improve camber in comparison with scale counterparts.
Similarly, 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 material. 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. He uses the real-life B-2 Spirit flying wing bomber as an example, stating that the weights along the wing should be put forward in order to stabilize the plane.
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. Independently, Edmond Hui invented a Stealth Bomber -like paper plane called the Paperang in ,  based on hang glider aerodynamics.
Uniquely, it has properly controlled airfoil sections, high-aspect-ratio wings, and a construction method designed to allow the builder to vary every aspect of its shape. It was the subject of a book, "Amazing Paper Airplanes" in , and a number of newspaper articles in 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 stability. In , origami artist Michael LaFosse designed a pure origami one sheet; no cutting, glue or staples Though 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 Press. Although 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 year-old paper plane  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 successfully.
After the folding there are still gaps between different layers of folded paper tearoff edge. These and the kinks transversal to the airflow may have a detrimental effect on aerodynamics, especially on the upper side of the wing. Bestselling Series. Harry Potter. Popular Features.
