element code that executes quickly because the blade section lift, drag and pitching moment coefficients are determined offline and stored in a lookup table. The sample cases provided by AMI used the XFOIL code [2] developed by MIT to calculate the 2D section lift and drag coefficients up to the stall angle. Beyond the static stall

Airfoils, Lift and Bernoulli's Principle

Near and beyond the speed of sound (about 330 m/s or 700 mph on earth), shock waves are produced that affect the lift and drag of the object. Density Altitude may be one of the most important factors affecting lift. Think about moving in water, versus moving in steam. ...

Drag Measurement

May 05, 2015· On this page, we will discuss the measurement of the drag force to demonstrate the basic principles involved with force balances. This configuration is called a one component balance since it only measures one force. There are more sophisticated, threecomponent balances that can simultaneously measure lift. drag and pitching moment.

The Four Forces | How Things Fly

Four Forces Affect Things That Fly: Weight is the force of gravity. It acts in a downward direction—toward the center of the Earth. Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
