Aircraft Horizontal Tail plane Case
- Model-test mismatch
- Inaccurate flutter and LCO predictions
- High test/model cost
- Lower performance
The HTP includes interface connections that demonstrate strong nonlinear behavior. These complex connections contributed to test-model differences and hence to the flutter prediction limitations.
Proper identification of the nonlinear connection and creation of a nonlinear model allowed to properly represent the dynamics of the aircraft structure.
Efficiency gain through fast and accurate test-model correlation. Better confidence in flight envelope prediction leading to enlarged flight envelope.
