- Thrust-Weight-Ratio
- The Ratio between the total mass of the vehicle and the available thrust of all propulsion devices of the vehicle/current stage. A TWR > 1 means the craft will have enough thrust to accelerate and ascend. A TWR below 1 won't be able to counteract gravity and drag at low altitudes, though a low TWR might totally suffice in space. Because the weight (W) of the craft depends on the current gravitational acceleration (g) the TWR depends on the position of the craft. The acceleration at Mün's surface is only 16.6 % of Kerbin's acceleration so at the surface a TWRKerbin = 1 would be a TWRMün = 6.
