Aircraft Horizontal Tail plane Case

Problem

  1. Model-test mismatch
  2. Inaccurate flutter and LCO predictions

Impact

  1. High test/model cost
  2. Lower performance

Root cause

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.

Solution

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

Benefits

Efficiency gain through fast and accurate test-model correlation. Better confidence in flight envelope prediction leading to enlarged flight envelope.
