The evolution of airplanes

  1. 1. By Christian<br />Product Evolution: Fixed-Winged Aircraft<br />
  2. 2. Unpowered Aircraft<br />Balloons, gliders, hang gliders, paragliders, kites<br />Fly without onboard propulsion<br />Most are mainly used for recreation<br />
  3. 3. Propeller Aircraft<br />Make use of reciprocating internal combustion engines that turns a propeller.<br />Quieter than jet aircraft.<br />Fly at lower speeds, and have lower load capacity that jet aircraft.<br />
  4. 4. Jet Aircraft<br />Make use of turbines for the creation of thrust<br />Greater weight capacity and fly faster than propeller driven aircraft<br />Very noisy<br />
  5. 5. Supersonic jet Aircraft<br />Military fighters and bombers, Concorde, and others.<br />Make use of turbines (often utilizing afterburners), that generate the huge amounts of power for flight faster than the speed of the sound(768 mph).<br />
  6. 6. Solar Powered Aircraft<br />Generates the needed energy by means of solar cells<br />Still mainly in experimental stages<br />
  7. 7. Unmanned Aircraft<br />No person aboard the aircraft and control is achieved remotely<br />Aircraft is controlled only by remote controls or other electronic devices.<br />
  8. 8. Rocket Powered Aircraft<br />Not in common usage today<br />Rocket-assisted takeoffs are used for some military aircraft.<br />SpaceShipOne is the most famous current rocket aircraft, being the test bed for developing a commercial sub-orbital passenger service.<br />
  9. 9. Ramjet Aircraft<br />A ramjet is a form of jet engine that contains no major moving parts.<br />The SR-71's Pratt & Whitney J58 engines ran 80% as ramjets at high speeds (Mach 3.2 or 2,304+mph) and have max altitude of 100,000+ ft.<br />
  10. 10. Scramjet Aircraft<br />Scramjet aircraft are in the experimental stage<br />The Boeing X-43 is an experimental scramjet with a world speed record for a jet-powered aircraft – Mach 9.7, nearly 12,000 kilometers per hour (7,500 mph) at an altitude of about 36,000 meters (118,000 ft).<br />
