Spacecraft Launcher Nozzle

Problem

1. Model/test mismatch

Impact

1. High test/model cost
2. Lower performance
3. High operation cost

Root cause

The nozzle was made of 2 main pieces joined by a combination of bolts and elastomeric joints. This complex connection was a source of nonlinearity which contributed to test-model differences.

Solution

Proper identification of the nonlinear connection and creation of a nonlinear model allowed to properly represent the dynamics of the spacecraft structure.

Benefits

Efficiency gain.

Lower launch cost through safety margin and weight reduction.
