  2. 2. What is an aircraft?<br />An aircraft is a vehicle which is able to fly by being supported by the air, or in general, the atmosphere of a planet.<br />Rockets are not considered aircraft because they do not rely on lift from aerodynamics to fly, relying instead on rocket thrust.<br />
  3. 3. First Flight<br />Orville and Wilbur Wright<br />December 17, 1903<br />First powered flight<br />Created method for pilots to control<br />Formula for lift – Smeaton coefficient<br /><br />
  4. 4. SmeatonCoefficent<br /><br />
  5. 5. 1903-1927<br />1903 – First flight by Wright Brothers<br />1909 – First flight across English Channel<br />1910 – Henri Fabre takes off from water<br />1914 – Aerial combat in WWI, no deaths<br />1919 – First transatlantic crossing by two<br />1922 – First successful parachute jump<br />1927 – Lindbergh flies solo across Atlantic<br /><br /><br />
  6. 6. 1927-1949<br />1929 – Fritz Opel makes first rocket flight<br />1937 – Hanna Reitsch pilots helicopter<br />1939 – First successful turbojet engine<br />1942 – Messerschmitt Me-262 is flown for the first time, the fastest aircraft of WWII<br />1947 – Yeager breaks sound barrier in X-1<br />1949 – B-50A circles the globe nonstop<br /><br /><br /><br />
  7. 7. 1952-Present<br />1952 – First commercial jetliner<br />1969 – Tu-144 jetliner breaks sound barrier<br />1981 – Solar powered craft flies across English Channel<br />1986 – Nonstop global flight without refuelling<br />2006 – Steve Fosset flies around the world twice<br />
  8. 8. Evolution<br />
  9. 9. Early aircraft design<br />Biplanes and triplanes<br />Number of wings meant lots of drag, but enough lift for low speed take-offs<br />Low performance<br />Weak engines<br />Wooden propellers<br />Rotary engines<br />Wooden construction<br /><br /><br />
  10. 10. Pinnacle of the Piston Engine<br />Transition to metals<br />Faster, higher flying<br />Larger payload<br />More agile<br />Powerful engines<br />Longer range<br />Hydraulic controls made high speed maneuvers possible<br /><br /><br />
  11. 11. First Turbojets<br />Turbojets used controlled explosion<br />More speed, power<br />Swept wing design lowered drag<br />Larger aircraft<br />Commercial aircraft becoming more common<br /><br /><br />
  12. 12. High Performance<br />Powerful engines such as the J-74 pushed speeds past mach 2<br />Extreme ranges and payloads possible<br />Engines became more efficient, afterburner introduced<br /><br /><br />
  13. 13. Commercial Enterprise<br />Boeing 707, Douglas DC-10 became successful<br />Efficient transport<br />More people could move through the air<br />Safe way of travel<br /><br /><br />
  14. 14. Turbofans Evolve<br />Turbofans increased efficiency<br />Fly-by-Wire<br />Increase in speed, range, payload<br />Turbofans used larger air compressors<br /><br /><br />
  15. 15. Next Generation<br />Experiments with forward swept wings for higher agility<br />F-35 JSF vertical take-off and landing<br />Improved computer power allows potentially unstable aircraft to fly with great agility<br /><br /><br />
  16. 16. Commercial Future<br />Automated landings<br />Larger passenger capacity<br />Longer flight range<br />More services onboard<br />Technologically rich environments<br />,0.jpg<br /><br />
  17. 17. Environmental and Social Impact<br />
  18. 18. Atmospheric Effects<br />Higher altitudes mean more effect of greenhouse gases on the Earth<br />Huge amounts of carbon dioxide emitted into the air<br />Approx. 1.5M people a day fly in the U.S.<br /><br />
  19. 19. Emissions Chart<br /><br />
