Walton Aero Propulsion PPT

  1. 1. Propulsion Reuben, Garrick, Collin
  2. 2. Piston Engine <ul><li>Standard Engine used in small aircraft </li></ul><ul><li>Piston torque and horsepower are decided by bore and stroke </li></ul><ul><li>Generally powers a propeller </li></ul><ul><li>Can be found in most transportation vehicles </li></ul><ul><li>Supercharges and Turbos can be added to increase power output </li></ul>
  3. 3. Radial Engine <ul><li>A radial engine has 1 or more rows of cylinders arranged in a circle around the crankcase. </li></ul><ul><li>Every row must have an odd number of cylinders, in order to operate smoothly. </li></ul>
  4. 4. Ethanol Power <ul><li>The incorporation of Ethanol into the production of airplane engines is a big breakthrough in the fight for supporting nature and reducing the amount of fossil fuels used in everyday flying.  </li></ul><ul><li>Fagen Inc. has taken Ethanol to a new level. It is now used for high performance stunts in air shows, instead of having low HP. </li></ul><ul><li>For Example: The Ethanol-Powered Fagen MX2 has a whopping 400+ HP and top speed of 275 mph. </li></ul>
  5. 5. Wankle Engine <ul><li>Internal Combustion engine; uses a rotary design </li></ul><ul><li>4 Stroke Cycle </li></ul><ul><li>Developed in the 1950’s and only recently was perfected by Mazda </li></ul><ul><li>Simpler, Lighter, and have less moving parts than piston powered engines of the same power output </li></ul>
  6. 6. Electric Engine <ul><li>Uses updraft from the props to store energy </li></ul><ul><li>Able to use solar power to help fly </li></ul><ul><li>Some have a battery for takeoff. After takeoff, it runs completely on solar power. </li></ul><ul><li>Generally glider shaped, for maximum lift with minimum power </li></ul>
  7. 7. Motorjet <ul><li>Very inefficient design for an aircraft engine </li></ul><ul><li>Drives a compressor which fires into the jet engine </li></ul><ul><li>Very fuel inefficient and produces less or equal power as a conventional jet engine </li></ul>
  8. 8. Pulse Jet Engine <ul><li>Low fuel economy, however, cheap and easy to build. </li></ul><ul><li>Not very fast </li></ul><ul><li>Pulse jet diagram: First part of the cycle: air flows through the intake (1), and mixed with fuel (2). Second part: the valve (3) is closed and the ignited fuel-air mix (4) propels the craft. </li></ul><ul><li>Used in a few German planes </li></ul>
  9. 9. Hyper Engine <ul><li>BMW 803 – one of the most powerful attempts at a hyper engine. </li></ul><ul><li>28-Cylinders, 3950 Horsepower </li></ul><ul><li>Crankshaft was too weak, so they used direct connected props. </li></ul><ul><li>HP/LB ratio is about 0.6 </li></ul>
  10. 10. Nuclear Engine <ul><li>Uses direct cycle jet engines powered by a nuclear reactor </li></ul><ul><li>Soviets were putting in great effort into developing the engine </li></ul><ul><li>Very unsafe, however very powerful if successful </li></ul>
