Discussion
Consider the following statements about landing load analysis:
1. The gear, tyres and airframe interact dynamically during the impact.
2. Drop testing of the complete gear is used to validate the analysis.
3. A static equilibrium calculation gives the peak loads accurately.
Which of the statements given above is or are correct?
Answer: A
Correct answer: 1 and 2 only
Statements 1 and 2 are correct: the impact is a dynamic event in which gear, tyres and airframe interact, and drop testing the complete gear is how the analysis is validated. Statement 3 is wrong - a static equilibrium calculation cannot capture the peak, because the peak depends on how fast the energy is absorbed, not merely on how much there is.
