Transcript

  • 1. Reuben, Garrick, Collin
  • 2.  Standard Engine used in small aircraft  Piston torque and horsepower are decided by bore and stroke  Generally powers a propeller  Can be found in most transportation vehicles  Supercharges and Turbos can be added to increase power output
  • 3.  A radial engine has 1 or more rows of cylinders arranged in a circle around the crankcase.  Every row must have an odd number of cylinders, in order to operate smoothly.
  • 4.  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.  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.  For Example: The Ethanol- Powered Fagen MX2 has a whopping 400+ HP and top speed of 275 mph.
  • 5.  Internal Combustion engine; uses a rotary design  4 Stroke Cycle  Developed in the 1950’s and only recently was perfected by Mazda  Simpler, Lighter, and have less moving parts than piston powered engines of the same power output
  • 6.  Uses updraft from the props to store energy  Able to use solar power to help fly  Some have a battery for takeoff. After takeoff, it runs completely on solar power.  Generally glider shaped, for maximum lift with minimum power
  • 7.  Very inefficient design for an aircraft engine  Drives a compressor which fires into the jet engine  Very fuel inefficient and produces less or equal power as a conventional jet engine
  • 8.  Low fuel economy, however, cheap and easy to build.  Not very fast  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.  Used in a few German planes
  • 9.  BMW 803 – one of the most powerful attempts at a hyper engine.  28-Cylinders, 3950 Horsepower  Crankshaft was too weak, so they used direct connected props.  HP/LB ratio is about 0.6
  • 10.  Uses direct cycle jet engines powered by a nuclear reactor  Soviets were putting in great effort into developing the engine  Very unsafe, however very powerful if successful
