Aerodynamics Dane Johannessen

Overview Aerodynamics What are the forces? How do these forces affect flight? What factors affect these forces?

What is Aerodynamics? The study of forces acting on an object in motion as it passes through air.

Laws of Motion Objects in motion stay in motion Force is the change in momentum with respect to time For constant mass For every action there is an equal and opposite reaction

What are the forces? Lift Drag Weight Thrust

Lift The vertical forces pushing up on a body during flight. General Equation: L = Lift Force ρ = density v = velociy A = area Cl = Lift coefficient that is usually determined experimentally

Lift in Air Foils Based on pressure differences (Bernoulli’s Principle) Top Higher velocity and decreased pressure Bottom Lower velocity increased pressure http://www.youtube.com/watch?v=zV06PgxarW0

Factors Affecting Lift Shape of object Higher curve = greater lift Size of the object L = constant x A Velocity of the object L = constant x v² Properties of the air L = constant x ρ Angle of attack Increased angle = increased lift

Demonstration For more information on paper airplanes Go here http://www.paperairplaneshq.com/

Drag Drag is the force that acts in the same direction as airflow General Equation: Fd = Drag Force ρ = density v = velocity A = area Cd = Drag Coefficient that is usually determined experimentally

How Shape Affects Drag Different shapes of the same frontal area lead to different drag coefficients:

Lift to Drag Ratio General Equation:

Weight Weight is the force on an object due to gravity Based on mass and gravitational acceleration General Equation: W = Weight Force m = mass g = gravity

Thrust Thrust is the force that propels an object through air General Equation: F = thrust force t = time m = mass v = velocity ṁ = mass flow rate ṁ = ρvA

Thrust Producers of thrust Main thing to take away Propellers Fans in jet engines Hot gases from rocket engines Main thing to take away Thrust must be greater than weight

Thrust to Weight Ratio General Equation: If F/W is high High acceleration High Climb rate If F/W > 1.0 Acceleration can be vertical

Summary Aerodynamics 4 Forces on a plane Lift > Drag Dependent on shape, size, velocity, air, angle Drag Dependent on shape Weight Thrust Lift > Drag Thrust > Weight
