Three series stages of a launch-system teaching architecture illuminate as mission time advances. Allocate a system reliability target equally, then compare actual subsystem rates against the implied rate budget.
• 3D scene parts: Stage A / power subsystem; stage b / control subsystem; stage c / propulsion subsystem; allocation budget display. • Controls: Required mission reliability (0.9–0.999 fraction); Mission duration (10–100 h); Stage A failure rate (0.0001–0.002 1/h); Stage B failure rate (0.0001–0.002 1/h); Stage C failure rate (0.0001–0.002 1/h). • Live readouts: System mission reliability; Equal subsystem target; Equal failure-rate budget (1/h); Reliability minus target. • Guided experiments: High subsystem rate; Tighter target. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.
Rsystem = exp[−(λA + λB + λC)tmission] Equal allocation Ri = Rtarget^(1/3) Equal rate budget = −ln(Rtarget)/(3tmission)
Representative systems-engineering teaching example. Equipment geometry and animation time are illustrative; this is not an equipment qualification, safety assessment or certification tool. Independent nonrepairable exponential components in series; constant failure rates. Motion is a mission-time sweep, not random failure sampling. No common cause, repairs or launch mechanics. Try the preset experiments, then compare the live readouts with the equations.
No. The stated model omits real qualification evidence and system-specific assumptions.
Allocate the system target to required subsystems.
