Drag on plate 1
Drag on plate 1
(OP)
Where I can find the drag on a plate moving at velocity V1 in a direction which is perpendicular to an air moving at V2. The air speed V2 is parallel to the plate while the plate moves to the side at velocity V1. What I am looking for is the drag resisting the V1.
If the air has zero velocity the drag was
DRAG = 0.5*ro*V1*V1*PLATE AREA*Cd.
How the parallel V2 affects the drag.
If the air has zero velocity the drag was
DRAG = 0.5*ro*V1*V1*PLATE AREA*Cd.
How the parallel V2 affects the drag.

Well, something like that - drawing with text isn't the easiest.

So simple!
32 years have past from the last time I calculated lift and drag (while I was an student in the aeronautics department).
I have found the free program FoilSim from NASA and with your help I can calculate the resisting induced lift.
Thanks

Not only did you provide a simple and concise answer to his question, but you even managed a little diagram in ASCII.

Drawing in ASCII takes patience and insanity - in equal measures.
