Aerospace calcs where every unit is accounted for
Performance and loads work mixes SI, imperial and atmospheric data. ProveCalc keeps every quantity with its unit, confirms that coefficients really are dimensionless, and leaves a worksheet you can hand to a reviewer.
Dimensionless means dimensionless
Every result carries its units, so a CL or a factor of safety that comes out with leftover units is visible at once instead of passing as a plausible number.
Works where you work
Offline by design: the calculation never leaves your machine, which matters for controlled data.
AI that drafts, not decides
Ask the assistant to set up a calculation from a sketch or a problem statement; it proposes worksheet steps you review, and the engine computes them.
What you can calculate
- ✓Lift, drag and required lift coefficient at a flight condition
- ✓Dynamic pressure and airspeed at altitude
- ✓Column buckling and effective length
- ✓Torsion of shafts: torque, shear stress and twist
- ✓Vector moments and forces in three dimensions
- ✓Space trusses, solved joint by joint and drawn in 3D
Worked examples
Euler buckling load of a pinned column
P_cr = 548.3 kN, so the factor of safety against buckling is 4.57.
Solid shaft in torsion: torque, shear stress and angle of twist
T = 98.79 N·m, τ_max = 18.63 MPa and the shaft twists 0.712° over 0.8 m.
Lift coefficient needed at cruise
q = 1921 Pa and the wing needs C_L = 0.378 for level flight.
Buy once, own it forever
$200 one time. No subscription, no renewal, and the version you bought keeps working.
No connection needed
Works offline. The only network use is checking for updates and a one-time activation check.
AI-native, never required
The assistant drafts on the same worksheet you work on. You can do everything without it, and it never does the math: the engine does, with units, and checks it.
