      • Know How... 168: Geared Turbofan, WinDroid, & Google History

        Pratt & Whitney's new Super Engine

      • Modern aircraft are all about the turbofan engine
      • The Turbofan combines massive amounts of power, with decent efficiency and impressive reliability.
      • Even the non-exotics are amazing works of engineering

        • Here's how a traditional turbofan works:

      • A Jet engine compresses air, adds fuel, burns it, then is thrusted forward by the expansion of exhaust gasses
      • A "Fan" moves huge amounts of air, thrusting itself forward (Think of the props on a Quadcopter)
      • A Turbofan combines the two: a HUGE fan in front of, and drive by a jet engine

        • In a modern high-bypass turbofan you have:

      • The Fan
      • The low-pressure compressor
      • The High pressure compressor
      • The Combustion chamber
      • High pressure turbine
      • Low pressure turbine

        • Here's the key

      • The low pressure turbine is connected by a shaft to the low pressure compressor and fan
      • The high pressure turbine is connected to the high-pressure compressor
      • So, as the gasses and burned and expanded, they provide the power to the fan and compressors that allow for the gasses to be burned and expanded.

        • This is a good system... but the folks at Pratt and Whitney just made it obsolete!

        The Pratt & Whitney "PurePower" Geared Turbofan

      • They burn 16% less fuel for the same thrust
      • They put out less NOX for the same thrust
      • The create 75% less noise while on the ground
      • It cost 30 years and $10 billion to make them work

        • Why is it so much better?

      • Let's talk about propellors.
      • Small props that spin quickly, vs large props that spin slowly
      • Large is more efficient, and less noisy
      • But we wouldn't use larger fans on Turbofans because the speeds as which you needed to spin the shaft for the compressors was spinning too fast for the ideal-sized fan.
      • So... P&W added a gear box (It's 20 inches in diameter and weighs 250lbs)

        • They used a orbital gear design to step down the speed of the low-pressure turbine/compressor shaft.

      • This allows the fan to spin much more slowly, but with far more torque
      • Slower speeds with more torque means they can use a more aggressive fan that moves more air at lower speeds.
      • While a traditional turbofan might have a 5:1 bypass... PurePower does 12:1

        • So... more efficient, more thorough burn (less pollutants), and MUCH quieter on the ground.

        WinDroid & Google History

        AMIDuOS!

      • Created by AMI - "American Megatrends - The company that so many of us know from their BIOS days"
      • They were founded in 1985 by Pat Sarma and S. Shankar (who will be on Triangulation in the future)
      • Their first customer was "PC's Limited" which became "Dell Computers"

        • But this is DuOS...

      • Unlike "Bluestacks" which is an Android App Emulator, DuOS is full-Android in either a VM or a Container
      • It gives FULL access to all the major peripherals (this was a major problem with emulators)
      • Keyboard, Mouse, touchscreen, microphone, ambient light sensor, accelerometers, compass, orientation, etc.
      • It also supposed variable screen sizes.

        • Notes:

      • There are two versions: AMIDuOS 1.1 (Running Android Jellybean) and AMIDuOS 2.0 (Running Android Lollipop)
      • Jellybean will cost you $10 // Lollipop will cost $15
      • Once you install, you WILL need to install Google Apps and Services

        • Let's talk about what Google stores in your online history

      • Websites
      • Voice Commands/Searches
      • Connected Devices
      • Location History
