Evolution of Airplanes By: Jared Hundt First Airplane • December 17, 1903- Orville and Wilbur Wright (aka-The Wright Brothers), created the first motor powered airplane. • The airplane was only in flight for 12 seconds, and traveled 120 feet. • The plane was made of wood and fabric, and the motor was a aluminum crankcase, which had 12 horse power. Wright Brothers First Metal Airplane • January 1st, 1917- Hugo Junker developed this airplane named the Junker J4. • Made out of a light weight aluminum called, duralumin. • Aeronautical Engineers found that there were many advantages of metal airplanes over wooden airplanes. It was more durable, to fire, did not absorb sun or moisture, and it gave the plane a sturdy structure. • Known as one of the greatest engineering successes in history. Metal Airplane The Radar • January 1st, 1935- Robert Watson-Watt, was the inventor of “The Radar,” short for “radio detection and ranging.” • This system used frequencies sent out and sent back to the radar on the airplane to show the pilot where enemy planes were located. First Jet Engine • January 1st, 1937- Frank Whittle and Hans von Ohain designed the first jet engine, which was made up of a fan, compressor, combustor, turbine, and nozzle. • August 27th, he Heinkel HE 178 was the first to fly with the new jet engine. • The engine allowed for much faster flight, and much more efficient flights. First Jet Engine Commercial Airplanes • On July 27, 1949, the first commercial airplane flight took place. • Then in 1969 the first wide winged commercial airplane was developed. • This airplane was called the Boeing 747, it had four engines, two decks, and it flew at high speeds. • This was the first step towards passenger transportation. • Something engineers did not think would happen until current day. But it happened 40 years early. Boeing 747 Airplanes Ainti-Radar • January 1st, 1990- Northrop Grumman developed the B-2 bomber. • What made the B-2 bomber near impossible to detect was what it was made out of. It was made out of composite material. • When other planes are made out of metal, wood, or fiberglass. • The composite material made airplanes more easily assembled, lighter, and more aerodynamic. • Another bomber named the F-117 stealth fighter was developed, also undetectable by radar. Stealth Bomber Modern Commercial Flight • September 1st, 2012- The eco friendly commercial airliner the A380 was created. • Only produces 75g of CO2 per passenger, which is way under the international limit per passenger. • This plane contains many recycled components, and recycles many things it uses, it is naturally lighted, and burns much less fuel. A380 Today’s uses of Airplanes • Mailing/Shipping-use the airplanes to deliver mail and ordered items. • Transportation- use Airplanes to travel almost anywhere around the world. • War- Use jets/drones to transport and assist troops. Future of Airplanes • The first major thing to accomplish will be a more fuel efficient plane. One that can run on electricity, or solar power. • Planes of the future will hopefully be a lot faster, and much more cost efficient. • And they will have new designs that look futuristic.

AMA FPG-9 Glider OBJECTIVES – Students Will Learn About the Basics of How Flight Works by Creating a Simple Foam Glider
AEX MARC_Layout 1 1/10/13 3:03 PM Page 18 activity two AMA FPG-9 Glider OBJECTIVES – Students will learn about the basics of how flight works by creating a simple foam glider. – Students will be introduced to concepts about air pressure, drag and how aircraft use control surfaces to climb, turn, and maintain stable flight. Activity Credit: Credit and permission to reprint – The Academy of Model Aeronautics (AMA) and Mr. Jack Reynolds, a volunteer at the National Model Aviation Museum, has graciously given the Civil Air Patrol permission to reprint the FPG-9 model plan and instructions here. More activities and suggestions for classroom use of model aircraft can be found by contacting the Academy of Model Aeronautics Education Committee at their website, buildandfly.com. MATERIALS • FPG-9 pattern • 9” foam plate • Scissors • Clear tape • Ink pen • Penny 18 AEX MARC_Layout 1 1/10/13 3:03 PM Page 19 BACKGROUND Control surfaces on an airplane help determine the movement of the airplane. The FPG-9 glider demonstrates how the elevons and the rudder work. Elevons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control). Thus, elevons at the wing trailing edge are used for pitch and roll control. They are frequently used on tailless aircraft such as flying wings. The rudder is the small moving section at the rear of the vertical stabilizer that is attached to the fixed sections by hinges. Because the rudder moves, it varies the amount of force generated by the tail surface and is used to generate and control the yawing (left and right) motion of the aircraft.

Glider Handbook, Chapter 2: Components and Systems
Chapter 2 Components and Systems Introduction Although gliders come in an array of shapes and sizes, the basic design features of most gliders are fundamentally the same. All gliders conform to the aerodynamic principles that make flight possible. When air flows over the wings of a glider, the wings produce a force called lift that allows the aircraft to stay aloft. Glider wings are designed to produce maximum lift with minimum drag. 2-1 Glider Design With each generation of new materials and development and improvements in aerodynamics, the performance of gliders The earlier gliders were made mainly of wood with metal has increased. One measure of performance is glide ratio. A fastenings, stays, and control cables. Subsequent designs glide ratio of 30:1 means that in smooth air a glider can travel led to a fuselage made of fabric-covered steel tubing forward 30 feet while only losing 1 foot of altitude. Glide glued to wood and fabric wings for lightness and strength. ratio is discussed further in Chapter 5, Glider Performance. New materials, such as carbon fiber, fiberglass, glass reinforced plastic (GRP), and Kevlar® are now being used Due to the critical role that aerodynamic efficiency plays in to developed stronger and lighter gliders. Modern gliders the performance of a glider, gliders often have aerodynamic are usually designed by computer-aided software to increase features seldom found in other aircraft.

Balloons and airships are lighter-than-air (LTA), and fly because they are buoyant, which is to say that the total weight of the aircraft is less than the weight of the air it displaces.1 The Greek philosopher Archimedes (287 BC – 212 B.C.) first established the basic principle of buoyancy. While the principles of aerodynamics do have some application to balloons and airships, LTA craft operate principally as a result of aerostatic principles relating to the pressure, temperature and volume of gases. A balloon is an unpowered aerostat, or LTA craft. An airship is a powered LTA craft able to maneuver against the wind. 1 NASA Web site U.S. Centennial of Flight Commission http://www.centennialofflight.gov/index2.cfm Does not Contain ITAR Controlled Data Atmospheric Airship Terminology • Dirigible – Lighter-than-air, Engine Driven, Steerable Craft • Airship –Typically any Type of Dirigible – Rigid –Hindenburg, USS Macon, USS Akron USS Macon 700 ft X 250 ft – Semi-Rigid – Has a Keel for Carriage and Engines • NT-07 Zeppelin Rigid – Non-Rigid – Undercarriage and Engines Support by the Hull • Cylindrical Class-C – “Blimp” – Goodyear, Navy AZ-3, Met Life Blimp, Blue Devil Simi-Rigid

RIGHT FLIGHT Objectives The students will: Construct a flying model glider. Determine weight and balance of a glider. Standards and Skills Science Science as Inquiry Physical Science Science and Technology Unifying Concepts and Processes Science Process Skills Observing Measuring Collecting Data Inferring Predicting Making Models Controlling Variables Mathematics Problem Solving Reasoning Prediction Measurement Background On December 17, 1903, two brothers, Wilbur and Orville Wright, became the first humans to fly a controllable, powered airplane. To unravel the mysteries of flight, the Wright brothers built and experimented extensively with model gliders. Gliders are airplanes without motors or a power source. 52 Aeronautics: An Educator’s Guide EG-2002-06-105-HQ Building and flying model gliders helped the Wright brothers learn and understand the importance of weight and balance in air- planes. If the weight of the airplane is not positioned properly, the airplane will not fly. For example, too much weight in the front (nose) will cause the airplane to dive toward the ground. The precise balance of a model glider can be determined by varying the location of small weights. Wilbur and Orville also learned that the design of an airplane was very important. Experimenting with models of different designs showed that airplanes fly best when the wings, fuselage, and tail are designed and balanced to interact with each other. The Wright Flyer was the first airplane to complete a controlled takeoff and landing. To manage flight direction, airplanes use control surfaces. Elevators are control surfaces that make the nose of the airplane pitch up and down. A rudder is used to move the nose left and right.
