Development of a magnetic suspension system for a wind-tunnel model levitating in two-degree of freedom

Abstract

A magnetic suspension system for a wind-tunnel model is developed. The goal of this development is to clarify flow fields around flying body in unstable motion. This system noncontactly supports a wind-tunnel model that includes a neodymium magnet. The model has two-degree of freedom, pitch rotation and translation in lift direction, during magnetic levitation in air flow of the wind-tunnel. This study reports the conceptual design of the magnetic suspension system which consists of magnetic circuit and a feedback control system.
