Rocket Thrust Calculator
Calculate rocket engine thrust from mass flow rate and exhaust velocity
๐ Rocket Thrust
Rocket thrust is the force produced by expelling propellant. It's calculated as the product of mass flow rate and exhaust velocity, plus pressure thrust from the nozzle.

๐ก Tips & Information
- Thrust is measured in Newtons (N) or pounds-force (lbf)
- Formula: F = แน ร ve + (pe - pa) ร Ae
- First term is momentum thrust, second is pressure thrust
- In vacuum, ambient pressure is zero
- Higher exhaust velocity and mass flow = more thrust
