A Comparison Of Aircraft Tire Skid With Initial Wheel Rotational Speed Using Ansys Transient Simulation
Based on heavy aircraft main landing gear tires touchdown skidding process, patents have been registered since
the 1940s to improve tire safety, decrease the substantial wear and smoke that results from every landing by spinning the rear
wheels before touchdown. A single wheel has been modeled as a mass-spring-damper system using ANSYS mechanical
transient simulation to analyze static and pre-rotating wheels behavior during a short period between touchdown and
skidding, to spin-up to reach the equivalent of the aircraft ground speed. In this paper, a case study is presented of a Boeing
747-400 main landing gear wheel to compare the skidding distance and time between initially static and pre-spun wheels.
