METHOD FOR DETERMINING THE AERODYNAMIC MOMENT OF RESISTANCE OF A WHEEL

摘要

A method for determining the aerodynamic moment of resistance Maero-EM of a wheel arranged on an axis, by measuring the value of the mechanical power Pm to be applied to the wheel in order to maintain it in rotation at a constant speed ω, the said wheel being equipped with a rotational-drive means and with a device for picking off and/or recording the numerical values of the said mechanical power and those of the rotational speed. The wheel is protected by a removable cap and is subjected to a flow of air.
