How Do I Compute Lift and Drag? | COMSOL Blog

Therefore, we will use total stress to compute lift. At a zero angle of attack, the lift is simply -spf.T_stressy. If the angle of attack is nonzero, we can project the force onto the direction of the lift using the following expression: spf.T_stressx*sin (alpha*pi/180)-spf.T_stressy*cos (alpha*pi/180).

An airplane in flight is always in the middle of a tug-of-war with the four forces. For an airplane to takeoff, thrust must be greater than drag and lift must be greater than weight. To maintain level flight, lift must equal weight and thrust must equal drag. For landing, thrust must be less than drag, and lift . [PDF]احصل على السعر

DRAG AND LIFT FORCE IN FLUID MECHANICS

Lift force is basically defined as the force exerted on the body in a direction perpendicular to the direction of motion when fluid is moving and body is stationary or body is moving and fluid is stationary. Lift force will be represented by the symbol FL. Where, CD = Co-efficient of drag. CL = Co-efficient of lift.

The lift/drag ratio increases very rapidly up to about 3 deg or 4 deg, at which angles the lift is nearly 24 times the drag (some aerofoils give an even greater maximum ratio of lift to drag); the ratio then gradually falls off because, although the lift is still increasing, the drag is increasing even more rapidly, until at the stalling angle ...

Lift-to-drag ratio. In aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by a wing or vehicle, divided by the aerodynamic drag it creates by moving through the air. The term is calculated for any particular airspeed by measuring the lift generated, then dividing by the drag at that speed.
