Abstract

A wear amount estimation device estimates plural kinds of wear energy depending on each of an internal pressure of aircraft tires, a load acting on the aircraft tires, a velocity of an aircraft, a slip angle caused in the aircraft tires, and a braking force of the aircraft, in accordance with each of these elements and wear energy EFR of the aircraft tires in a state of a free rolling run The wear amount estimation device estimates the wear amount wear of the aircraft tires in accordance with each of the calculated wear energy and a wear resistance R indicating a relationship between predetermined wear energy and a predetermined wear amount.
