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.
