Evaluation of a rocket burnout velocity from ground and free flight tests
Abstract
A new methodology was developed for preparation of Firing Tables in which the effective burnout velocity is evaluated both from the static stand data and from the free flight trajectory measurements. The initial velocity of the powered free flight phase (rocket leaves the launcher) was measured by fixed cameras. That velocity is used to initialize the simulation from which the burnout velocity was evaluated. A very good agreement between the simulated velocities (from the powered and ballistic phase data) and that measured by fixed cameras was achieved. Combining the ground test measurements and the free flight test results reduces enormously the number of rockets to be fired. It is highly cost-effective and efficient.
