This document provides instructions for making different paper airplane models and their history. It discusses how the Chinese were the first to make paper airplanes 2000 years ago and how paper modeling became popular during World War 2 due to material restrictions. Fifteen different paper airplane models are listed along with tips for accurate folding and safe flying. In conclusion, the author enjoys making paper airplanes as a hobby with children.
The first autopilot was developed in 1912 by Sperry Corporation. It connected gyroscopic instruments to aircraft controls, allowing planes to fly straight and level without constant pilot input. In 1914, Lawrence Sperry demonstrated the autopilot by flying with his hands away from the controls. Autopilots greatly reduced pilot workload on long flights and helped enable transoceanic flights. Modern autopilots are computer controlled and can fly planes through all phases of flight except taxiing, with some able to perform automatic landings. They integrate with inertial guidance and radio navigation to fly precision routes while minimizing errors over long durations.
In Interval 1 of the Balloons module, students will:
1. Learn about the history of hot air balloons and the achievements of the Montgolfier brothers, including their first manned flight in 1783.

“History of Aviation the Wright Brothers”
Claim: Wright Brothers started the history of aviation.
Reasons:
· Bishop Wright one day brought Wilburn and Orville Wright a small toy helicopter that was made up of wood and two curled rubber bands as a small propeller. Both the brothers played with it until it broke. After that, they made new copies of toys themselves. They also sold their toys to their friends. So it developed an interest of flying in them.
· Wright Brothers started the printing business in 1889 together but after 3 years they started the business of bicycle. They started selling repaired bikes initially. They establish their own brand in 1896. By working on bikes Wright Brothers generated an idea of flight.
· They used the technology about which they got knowledge from bicycles on airplanes.
· That technology included spoke wires, sprockets, chains, and ball bearings. From bicycles they learned to balance and control their aircraft.
· Orville and Wilburn Wright performed different experiments to fulfill their dream of inventing an aircraft.
· They also learned different techniques to control aircraft such as they realized the need of 3 axes of motions.
· Orville and Wilbur got this idea from the flying bird. They saw the birds twisting and curving their wings.
· They also performed Kite/glider Experiments.
· In 1899 the Wright Brothers began their research on aeronautical research. They used to test their notions of aircraft with a small kite having a five-foot wingspan. They built a machine in 1900 that carry a pilot in it.
· Their 1900 aircraft was not that successful so they flew it as a kite and collected information to improve the functioning of their machine.
Assumptions:
· Innovators made several assumptions about the development of flight. Since all the animals that fly have wings so innovators though of developing strap on wings. To test their assumption they would have to jump from the tall building.
· Some other innovators built flying machines and took years to build costly prototypes. All of them failed during the testing process.
· The modern innovators can learn from the approaches adopted by Wright Brothers.
· The Wright Brothers were flawless experimenters.
· They adopted simple and low-risk ways to test their assumptions.
· Wright Brother flew kites to test their assumptions.
· The Innosight advised a big consumer product company to deliver a device to centralized points on campuses.
· The business plans were assumed to take 3 months to get approval to sell their devices at school. They could pilot the idea at dew schools. But school slowly processes that approval because they assumed to approach it differently.
Backing:
· As Wright Brothers started their aeronautical research in 1899, the first aircraft they flew was a kite.
· Their first experiment did not produce less lift than expected. They tested small wing model to simulate fl ...
This chapter discusses the author's interest in watching a flat Earth video in early 2016 after the US election primaries had concluded. It provides context about the author's interests in politics, biblical archaeology and banjo playing. The author decides to research flat Earth by reading online before watching videos. One video by Matt Boylan discussing Wikileaks piqued his interest and caused him to reconsider what he had been taught about the globe Earth model.
The Wright brothers faced many challenges in their quest to achieve powered flight but were determined problem solvers. They studied birds in flight and designed gliders to understand control. After many glider tests and wind tunnel experiments, they built the first successful airplane in 1903. Although early flights had issues, the Wrights persisted through failures until achieving the first 12-second flight. Their scientific approach and refusal to give up led to conquering what many thought impossible.

The Wright brothers, Orville and Wilbur, were pioneers of aviation who achieved the first controlled, powered and sustained heavier-than-air human flight. After years of research and experimentation with gliders, by December 1903 they had developed flying machines that could take off, fly, and land safely with an operator aboard. On December 17, 1903, near Kitty Hawk, North Carolina, Orville piloted the Wright Flyer which achieved the first successful controlled, powered flight in a heavier-than-air aircraft, staying aloft for 12 seconds on a 120-foot flight. This achievement by the Wright brothers is recognized as the first controlled, powered and sustained heavier-than-air human flight and marked the
The document discusses the history and development of airplanes from their invention by the Wright brothers in 1903 through World War 1 and beyond. It describes how both the German and Allied militaries began using airplanes for reconnaissance and other military purposes during WWI, with the Germans being more open to the new technology early on. It also discusses how airplanes transformed from mainly being used for transporting mail and cargo after their invention to playing a larger military role during the war.

Kites originated in China in 549 AD using materials like silk and bamboo. They were later used by a Korean general in 788 AD to scare enemies by making kites look like cannonballs. Kites have been used for both transportation and recreation purposes, such as games in Afghanistan where people cut down each other's kites. Understanding aerodynamics from kites helped with designing planes and remote controlled vehicles. The presentation provides basic instructions on how to construct a simple kite using paper, sticks, string, and tying techniques.
This document provides an overview of model aviation as an educational activity for young people. It discusses the history of model aviation, including the first rubber-powered planes and model airplane clubs. It also covers building materials, tools, flying techniques, and how model aviation can teach principles of physics, mathematics, design, and testing theories through the building and flying of model planes. Safety is emphasized as the most important aspect for any youth activity.
The document summarizes milestones in early aviation history. It describes early attempts at flight dating back to 400 BC involving wooden pigeons and kites in China. In the 1500s, Leonardo da Vinci designed ornithopters but the attempts at flapping wings failed. In 1783, the Montgolfier brothers demonstrated hot air balloon flights up to 6000 feet but they lacked control. Later attempts added directional control through elongated balloons. In the 1890s, German scientist Otto Lilienthal conducted over 2500 flights with gliders, gaining insights until his death in a crash. The Wright brothers later built on this work to achieve the first sustained, controlled airplane flight.

Title : Have a fun by flying paper airplanes
Article Author: Gangadhar BK [MS], [BE], JNVD 99passout, presently working in Honeywell as a senior engineer.
Introduction : Children love making and flying airplanes. It’s a kind of a hobby to be them. Making a paper airplane is
very easy and less time consuming. These planes are made from a standard sheet of printer paper. I hope this article will
bring inspiration and help you to design your own paper airplanes.
History of Paper Airplanes: It is generally believed that Chinese were the first to build Paper Airplanes and kites
made out of papyrus paper around 2000 years ago. Since Chinese were early innovators and invented paper “as we know
it today”, it follows that they would be among the first to find creative uses for the new substance.
The Montgovier brothers used paper to build hot air balloons. Later they used paper lined cloth to build the first human
carrying hot air balloons in 1783. The Wright brothers reportedly use paper planes, wings and airfoils in wind tunnels as
part of their quest to build the first powered human carrying airplane. In the 1930s an English business man named Wallis
Rigby brought his paper modeling company to the United States.
During World War II governments around the world restricted the use of many materials necessary for the war effort.
Wood, plastic, metal and other materials could no longer be spared for toys. Paper on the other hand was available and
became a popular material for toy making. Consequently paper modeling became popular.
After the war ended the popularity of paper models declined as the restrictions on materials was eased. In many Eastern
block countries the popularity of paper planes continued because of the difficulty of getting affordable models in those
countries.
Guinness Records with paper airplanes: Ken Blackburns currently holds the Guinness Book of World Record
for time aloft for paper airplanes. He first set the record in 1993(16.3seconds), resetting it in 1987(17.2 sec), 1994 (18.8
sec) lost the record in 1996 and set the current record of 27.6seconds on 10/8/1998 in the Georgia Dome. He currently
lives with his wife in laurel Hill, Florida and works for Jacobs Engineering as an aeronautical engineer doing research with
the Air Force at Eglin Air Force Base. One sample airplane making steps: Interceptor
Orient the template with the “UP” arrow at the top of the
page. Then, flip the paper over onto its backside
Pull the top right corner down toward you until fold line1 is
visible and crease along the dotted line. Repeat with the top
left corner.
Fold the right side over again and crease along fold line 2. Fold the nose down toward you along fold line 3.
2. 2
Fold the nose back up and crease along fold line 4. Fold the tip of the nose back away from you and crease
along fold line 5.
Flip the plane over. Fold the right half of the plane over
onto the left half along fold line 6. Cut along the dotted line
7 for the vertical stabilizer.
Flap
Tuck the flap that was formed by your cut between the two
halves of the plane and crease it along fold lines 8.
When you have completed the step above, your plane will
look like this.
Fold the wings down along fold lines 8 and the winglets up
along fold lines 9. Add wing dihedral by tilting the wings up
slightly away from the fuselage. The wings will have a slight
“V” shape when viewed from the front.

Folding Technique: Folding technique is very important for successful flights. Make each of the folds carefully and
accurately according to the instructions and steps. Creases should be made by applying pressure to the fold with the edge
of your thumbnail. This is best achieved by holding your thumbnail on the fold, applying pressure, and pulling your thumb
along the fold line toward you. This will produce clean, crisp folds that will allow for accurate paper planes. If you make a
mistake on a fold that you cannot correct, don’t be discouraged! Just print another template. EVERY paper airplane
needs fine-tuning to achieve its best performance.
Safety: NEVER throw a paper airplane at another person, animal, or object that could be damaged. Paper planes can
have sharp edges and points that can injure someone, if you are not careful. Plan ahead and fly in a park, playground, or
backyard.
Conclusion: This is one of my hobbies - making paper airplanes and I enjoy it in office and home with my son and other
children.
