Calculate tsiolkovsky rocket equation to estimate maximum change of velocity of the vehicle by using simple astrodynamics calculator online.

The Tsiolkovsky rocket equation, or ideal rocket equation, describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself (a thrust) by expelling part of its mass with high velocity and thereby move due to the conservation of momentum. The equation relates the delta-v (the maximum change of velocity of the rocket if no other external forces act) with the effective exhaust velocity and the initial and final mass of a rocket (or other reaction engine).

Calculate Maximum Change of Velocity of Vehicle

Formula:

Δv=velnm0mf

where,

Δv (delta-v) = the maximum change of velocity of the vehicle.

m0 = the initial total mass, including propellant.

mf = the final total mass without propellant, also known as dry mass.

ve = the effective exhaust velocity.

ln = refers to the natural logarithm function.
