Tire Selection for a Military Training Aircraft

Abstract

AbstractThe aircraft tire is a complex, composite product of vital importance to all aircraft composed of rubber compounds (elastomers), fabric materials (nylon, aramid, or Kevlar), and steel wires (wire beads). The aircraft tire is subjected to very high mechanical stresses during parking, takeoff, and especially on landing, various thermal demands, solar radiation, the action of ozone, and partial discharge of the electrostatic charges accumulated on the outer surface of the aircraft. From the construction point of view, tires are bias tires or radial tires. Most aircraft tire companies recommend inflating their tires with nitrogen because it keeps out moisture, protects against corrosion, promotes compatible pressure, and is nonflammable. The selection of aircraft tires is made according to the stress to which tires are subjected and according to the recommendations of aircraft tire companies, based on the application of the Taguchi classification and the AHP multicriteria analysis methodology.
