Fundamental study on magnetorheological fluid brake for regional jets

Abstract

　Non-contact type brake is excellent in maintainability so it is optimum as an axle brake for aircraft. In this paper, basic experiments were carried out using magnetrheological fluid brake experimental equipment to study non-contact type brakes, the axle size of regional jets was investigated. The maximum brake torque of a regional jet's axle size based on the experimental equipment was 2,421 Nm. This can satisfy only about 27 % of the necessary torque. In order to increase brake torque, increase the number of discs and decrease the gap h.
