Find the burnout velocity of a rocket with Hydrogen-Fluorine as the fuel oxidizer combination.
Find the burnout velocity of a rocket with Hydrogen-Fluorine as the fuel oxidizer combination. Ratio of initial weight before making blast off to the final weight at burnout is 7.
Burnout velocity of a rocket is the velocity of the rocket at the time when there is depletion of the fuel and oxidant or the propellants. It is the maximum velocity achieved by a rocket. Burnout velocity is given as:
\[{V_b} = {g_0}{I_{sp}}\ln \left( {\frac{{{M_i}}}{{{M_f}}}} \right)\]
\[ \Rightarrow {V_b} = \left( {9.8} \right)\left( {390} \right)\ln \left( 7 \right) = 7437.27\,m/s\]
