The following values are required for computing the ballistics analysis:

Value \(p\) is estimated by following approximation

\( 3.0099 - 0.868106 \log_{e}(0.0014659D_h + 7.88959) \)

The formula is only accurate from 0 to 10000 barometric meters of altitude


Drag for any given velocity is determined by this formula

\( F_D\ = C_d * \frac{ p * V^{2} }{2} * d * \pi \)


The final distance per flight section achieved \( \Delta d \) is determined through the sum of integrals for each engine-phase.

The constraints \(a\) and \(b\) represent the phase of flight in seconds, where \( x = V \) and \( a > t(F_E) > b \).

Each flight section \(a\) to \(b\) is determined by the total engine stages + 1 (terminal phase where \( F_E = 0 \)).

\( \Delta d = \int_a^b \,dx = \frac{F_E - F_D}{m} \)
