Built-In DOE & Optimization
Run design of experiments and optimization studies at the component or full-system level to identify optimal sizing, weight, and performance trade-offs without external tools.
Thermal-Hydraulic Performance Analysis
Capture thermal effects within the hydraulic circuit, including heat generation from hydraulic losses and water hammer events, to support component sizing and system-level thermal performance analysis.
Water Hammer & High-Frequency Dynamics
Simulate high-frequency hydraulic phenomena including water hammer, cavitation, aeration, and compressible liquid behavior to accurately predict transient loads and pressure surges across the landing gear system.
Unified Landing Gear Development
Develop and integrate hydraulic actuation, multi-body mechanics, oleo strut design, actuators, detailed pump dynamics, and braking within a single simulation environment, eliminating the need for multiple disconnected tools.
Landing Gear FAQs
Answers to the most common technical questions from engineers evaluating GT-SUITE for landing gear applications
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.
