→Limit and failure modeling

Component failure is modeled gradually where applicable - while a tire can only blow or not blow, an airfoil or a thruster for instance may lose a certain percentage of its efficiency. | Component failure is modeled gradually where applicable - while a tire can only blow or not blow, an airfoil or a thruster for instance may lose a certain percentage of its efficiency. | ||
In addition to failures induced by limit violations, the simulation also supports failure scenarios designed to model typical failure modes which could be expected to occur during operations, such as for instance engine failures or lock-up on ascent, coolant loop failures or leaks or similar. Rather complex chains of failures are modeled, for instance a failure of a coolant water spray boiler will lead to subsequent overheating of an APU unit - if this is not realized and proper action taken, the APU will fail subsequently, causing in turn a failure of one hydraulic system which potentially causes downstream failures of airfoil actuators or main engine gimbal capability. | |||
