Change an aircraft. See what happens. Fly the result.
Start with a working aircraft, adjust one part, and AeroForge shows how that choice changes stability, speed, efficiency, and takeoff. No aerospace background is required.

01
T-2
Cadet
Stable beginner trainer
Rotation and natural stabilityRotation is the gentle nose-up input used at takeoff speed. Natural stability describes whether the aircraft tends to settle after a disturbance.Make first lift
Fly the baseline Cadet. Rotate gently at Vr and establish a positive climb without exhausting the stall margin.
Why this aircraft works
A straight high wing, moderate dihedral, and forward center of mass make disturbances settle instead of grow. The root stalls first, preserving aileron authority.

R-70
Peregrine
Efficient regional turboprop
Aspect ratio and induced dragAspect ratio compares wing span with area. Induced drag is the drag cost of producing lift, especially at low speed.Stretch for efficiency
Increase the Peregrine wing span by 2 metres. Predict the efficiency change, then test its new takeoff behavior.
Why this aircraft works
A straight, slender high wing is efficient at regional speeds. Large propellers move a large mass of air gently, producing useful thrust without jet-level fuel flow.

PJ-12
Solace
High-speed private jet
Wing sweep and low-speed liftWing sweep helps high-speed flight but reduces the wing’s useful low-speed lift.Trade speed for runway
Reduce the Solace wing sweep by 5°. Compare its rotation speed with the baseline and identify the cruise-speed compromise.
Why this aircraft works
A moderately swept wing balances fast cruise and landing speed. Tail-mounted engines keep the cabin quiet but ask more of the rear structure.

X-17
Vesper
Agile fighter research aircraft
Center of gravity and static marginStatic margin compares the center of gravity with the neutral point. A smaller positive margin feels more responsive; a negative margin is unstable.Move toward agility
Move the Vesper center of mass aft by 2% MAC. Watch the stability feedback, then test the more sensitive aircraft.
Why this aircraft works
Sweep and a low aspect ratio reduce transonic penalties but increase induced drag. A small static margin makes the aircraft agile and demanding.

W-900
Stratos
Long-range wide-body laboratory
Mass, wing loading, and runway lengthWing loading is aircraft mass divided by wing area. More loading usually raises takeoff and landing speed.Load the long-haul flight
Add 10,000 kg of payload to Stratos. Predict the change in rotation speed and runway distance before flying it.
Why this aircraft works
Long wings reduce vortex drag, sweep protects high-speed cruise, and a long tail arm provides stability without an oversized stabilizer.

Calculation model
The visible aircraft and the numbers use the same inputs.
Faster air pushes harder — that’s dynamic pressure, and it grows with the square of speed. The wing turns that motion into lift; its area and shape also determine how much drag the aircraft pays for that lift.
Wing loading
Mass divided by wing area
Higher loading usually means a faster stall and landing, but a steadier ride in turbulence.
Aspect ratio
Span squared divided by area
Long, slender wings reduce induced drag but demand more structural stiffness.
Static margin
CG relative to the neutral point
A forward margin self-corrects pitch. Too much feels heavy; too little can become unstable.
Tail volume
Area multiplied by lever arm
A smaller tail can still be effective when placed farther from the wing.
Glossary
Plain language first.
Angle of attack
The angle between the wing and the air hitting it. People mix this up with the aircraft's pitch, but they're not the same thing.
Aspect ratio
Wing span squared divided by wing area. For a roughly rectangular wing, that is also span divided by mean chord. Long, slender wings usually reduce induced drag.
Dynamic pressure
The air’s motion pressure, ½ρV². Doubling speed produces four times as much dynamic pressure.
Induced drag
The drag cost of making lift. It is largest when an aircraft is slow and working hard.
Lift-to-drag ratio
How much lift the wing produces for each unit of drag. Higher values mean better aerodynamic efficiency.
Static margin
A first-order measure of pitch stability based on center of gravity relative to the neutral point.
Stall
The wing loses lift because the angle of attack got too steep for the air to follow the surface. Nothing to do with the engine.
Wing loading
Aircraft mass divided by wing area. Higher loading generally raises stall and landing speed.
