AVS 1200 Lecture Notes - Lecture 1: Maximum Takeoff Weight, Relative Wind, Airfoil
Document Summary
Chord: straight line from the leading to trailing. Relative wind: wind opposite to the direction of your movement. Angle of attack: angle generated by the airfoil with the relative wind (alpha) Bernoulli: experiment with air acting like liquid. Newtonian: laws of motion, every force has equal and opposite force, air under wing. Laminar flow: smooth ow over airfoil, not smooth is turbulence, lift reduced. Payload: weight that aircraft is carrying that is earning money. Zero fuel weight: weight of fuel when empty. Ramp weight: waiting to start engines before takeoff, slitty more than max takeoff because of burning fuel while taxiing. Gas turbine engines: pulls air into engine through the tube at front, add combustable material, ignite it, air expands, accelerates. Rocket engines: generate thrust by mixing two components, carries own source of oxygen and propellant. Induced drag: generated by the fact that we are making lift. Parasitic drag: shape of airplane generates drag.
