Feasibility Study for Using Low Boiling Point Fluids to Change Aircraft Tire Deflection

摘要

An investigation carried out over a one year period showed that the use of small quantities of low boiling point liquids in the cavity of an aircraft tire results in a faster pressure rise than would be the case if the liquid were absent. This effect causes a correspondingly greater decrease in tire deflection, with less heat generation. This effect is most pronounced as significant heat is generated in the tire, typical of long taxi distances on the order of 15,000 feet or greater. At shorter or normal operational taxi lengths, less than 10,000 feet, the effect is not significantly pronounced and does not yield the required stable, safe, and typical operational values of tire deflection. Hence, the proposed concept as a self healing solution to the problem of excessive heat generation during high flotation operations appears to be infeasible.
