Modeling of a hydraulic arresting gear using fluid-structure interaction and isogeometric analysis

- (FSI) analysis of a hydraulic arresting gear is performed.
- Analysis is performed at full scale with careful experimental validation.
- New geometry modeling platform for IGA is employed.
- Platform illustrates natural application of IGA to the problem class.
- Excellent agreement is achieved with the experimental data.

Fluid-structure interaction (FSI) analysis of a full-scale hydraulic arresting gear used to retard the forward motion of an aircraft landing on an aircraft-carrier deck is performed. The simulations make use of the recently developed core and special-purpose FSI techniques for other problem classes, specialized to the present application. A recently proposed interactive geometry modeling and parametric design platform for isogeometric analysis (IGA) is directly employed to create the arresting gear model, and illustrates a natural application of IGA to this problem class. The fluid mechanics and FSI simulation results are reported in terms of the arresting-gear rotor loads and blade structural deformation and vibration. Excellent agreement is achieved with the experimental results for the arresting gear design simulated in this work.
