Title:
IMPROVEMENT OF OPERATION STABILITY ACHIEVED BY EFFECT OF ROTATION DRIVE OF AIRCRAFT TIRE WHEEL DUE TO AIRFLOW VELOCITY AND PROFIT-AND-LOSS EFFECT DUE TO TIRE DAMAGE SAFETY
Document Type and Number:
Japanese Patent JP2015016847
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize operation stability, stability of the attitude of an airframe on landing, an economic effect of reducing exhaustion of consumable members and prevention of damage to airframe members by debris produced on rupture breaking by an effect of rotating the tire wheel of a landing gear of an air craft.SOLUTION: A knife cut groove A-A' is provided in a circumferential-part surface (tread part) of a ground surface of a tire, and a convex part B-B' is provided in the side-surface part. A tire wheel is rotated at a high speed by utilizing resistance energy of air flow. Securing stability of the attitude on landing, a profit-and-loss effect of the drive force produced by rotation force of the tire wheel on the runway surface, elimination of harmful factors in a state where bouncing occurs at an early stage and reduction of tire wear and damage are realized by securing rotation energy, with inertial energy of the rotation and a gyro effect by the rotation force combined, and releasing and discharging the rotation energy again.
