Burnout Mass of a Cold Gas Propulsion Rocket In The Context of Rocket Equation Calculator

The burnout mass of a solid-liquid rocket refers to the mass of the rocket after both the solid and liquid propellants have been fully consumed. In the context of the rocket equation, this parameter is essential for assessing the rocket’s performance characteristics.

The rocket equation for a solid-liquid rocket can be expressed as:

Here’s the formula for calculating the burnout mass of a rocket in the context of the rocket equation, expressed in SI units:

Where:

• m_f is the burnout mass of the rocket (kg),
• m₀​ is the initial mass of the rocket, including propellant (kg),
• $\Delta V$ is the change in velocity required for the mission (m/s),
• I_sp​ is the specific impulse of the rocket engine (s),
• g₀​ is the acceleration due to gravity at the Earth’s surface (approximately 9.81 m/s^s)
• $e$ is the mathematical constant approximately equal to 2.71828.
