Thrust-to-Weight Ratio

The TWR determines whether a vehicle can lift off and how quickly it accelerates.

Formula

TWR = F / (m * g)

  • *F* = engine thrust in newtons
  • *m* = total vehicle mass
  • *g* = local gravitational acceleration

    • TWR must exceed 1.0 for liftoff. Most launch vehicles aim for 1.2 to 1.8 at ignition.

    Ejemplo Resuelto

    Saturn V first stage: 7 607 000 N thrust, 549 054 kg.

    1. TWR = F / (m * g)
    2. Weight = 549054 * 9.80665 = 5 384 000 N
    3. TWR = 7607000 / 5384000
    4. TWR = 1.413
