Change the conditions. Watch the airflow. Discover how a swept-wing aircraft responds as angle of attack rises toward a stall.
teaching modelOriginal simplified 3D reconstruction. Not an official F-15 asset or a flight simulator.
Start with a question.
Choose a guided setup, change one condition at a time, and capture the force readings in your notebook.
How does speed affect aerodynamic force?
Start at 70 m/s and capture a reading. Raise speed to 140 m/s while holding angle and density steady. Capture again and compare.
Look for: lift and drag should each be about four times greater because dynamic pressure scales with speed squared.

From flow to force.
L = ½ρV²S CLLift grows with air density, the square of speed, reference area, and lift coefficient.
D = ½ρV²S CDDrag uses the same dynamic pressure. Its coefficient includes baseline, induced, and a teaching approximation for separated-flow drag.
Readouts use S = 1 m² to show force per area. Coefficient curves and the 15° stall threshold are illustrative, not measured F-15 data. They omit Mach effects, Reynolds number, trim, weight, thrust, and control laws.
Find the stall boundary.
Hold speed steady. Increase angle of attack from 6° past 15°. Lift first climbs, then falls as our model represents separated flow. Drag continues to rise. Lower the angle to restore attached flow.
Record what you observe.
Capture the current controls and readouts, then compare trials. Notes stay in this browser.
