Model development


Engine performance - Thrust profile

- Mass profile

Mission concept - Event sequence & timing

- Launch azimuth, elevation & altitude

Geometry & mass properties - Masses

- Center of graviities

- Moments of Inertia

Aerodynamics - Aerodynamic coefficients

Failure modes - Reliability / Failure probabilities

- Vehicle response to failure

- Breakup characteristics


Monte Carlo simulation

Typical computational statistics:

• 16 million simulation runs

• 80 million debris impacts

• Three calendar days for computer runs, plus post-processing
