SDI's Landing Gear Multifidelity Simulation and Subsystem Analysis Tool
GearSim reduces the resources needed during the product development cycle of landing gear subsystems. The software enables countless tests to be conducted virtually helping our customers minimize both costs and time needed to deliver a project.
GearSim provides a high level of modeling detail without requiring a high level of modeling expertise. Reduced modeling effort allows customers without landing gear experience to efficiently perform landing gear analysis tasks.
Experienced users can utilize GearSim as a central platform to connect specialized subsystem models and manage multiple, highly detailed landing gear and aircraft models.
