Description[edit | edit source]

This simple calculator determines the minimum average thrust required to maintain a 5:1 thrust to weight ratio.

Usage[edit | edit source]

  1. There are several ways to invoke the command:
  2. Enter the weight of your rocket.

Calculation[edit | edit source]

Thrust to weight is calculated using the following formula:

Tmin=5mg

where

Tmin= recommended minimum average thrust
m= mass of the rocket
g=9.807m/s2, acceleration due to gravity

Units[edit | edit source]

Calculations are done using metric units, but will display in your preferred units. Values can also be entered using any supported units by including the units with the value (eg 5 oz, or 23.2 g)
