 Rocket mass ratio

ID: rocket-mass-ratio

The rocket mass ratio compares the initial and final total rocket masses for a burn. It is dimensionless, and the ideal rocket equation becomes

Δ v = u ln R

. For the same fixed rocket exhaust speed, two successive burns with rocket mass ratios

R_{1}

and

R_{2}

R_{1} R_{2}

and total velocity gain

u ln R_{1} + u ln R_{2}
