Multi-Domain Hydraulic Integration
Integrate hydraulics with 1D, 2D, or 3D rigid or flexible body mechanics.
Solutions
Landing Gear Simulation
Design, analyze, and optimize aircraft landing gear systems within GT-SUITE
Solution Overview
Robust Gear Modeling
Models can be used to study performance of the landing gear, retraction, extension, steering, and braking.
GT-SUITE’s comprehensive library of templates empowers users to quickly create complete landing gear system or component level models. Within system level models, fidelity of components (pumps, valves, linkages, etc.) can be easily interchanged. Advanced thermal hydraulic models integrated with multi-body mechanics enable studies of component sizing as well as high frequency behavior such as water hammer effects.

Landing Gear FAQs
Find answers to common questions about using GT-SUITE for landing gear simulation.
-
What types of landing gear systems can GT-SUITE simulate?
Landing gear modeling in GT-SUITE spans the full system: hydraulic actuation for extension and retraction, oleo strut dynamics, steering mechanisms, braking systems, actuators, detailed pump behavior, and FPMU (Flight Power and Motion Unit) components.
-
How does GT-SUITE integrate hydraulics with mechanical dynamics for landing gear modeling?
Hydraulics and mechanical dynamics are coupled directly in GT-SUITE, combining 1D, 2D, or 3D rigid and flexible body mechanics in one environment. This lets engineers analyze fluid behavior and mechanical response together, rather than stitching results from separate tools.
-
Can GT-SUITE handle high-frequency hydraulic effects in landing gear systems?
High frequency hydraulic behavior, including water hammer, compressible liquids, cavitation, aeration, and gas transport, is captured through a fully transient Navier-Stokes solver built into the platform. This gives engineers the transient fidelity needed to evaluate fast acting landing gear hydraulic events, not just steady state flow.
-
How does GT-SUITE support landing gear development from CAD to full system optimization?
The workflow starts with CAD: 3D geometry can be converted automatically into a 1D flow system model, cutting down manual setup time. From there, electrical and control components can be layered into the same model, and built in DOE and optimization tools carry the analysis from individual component sizing all the way to full system performance tuning.
