HELIUM USED IN TYRES.
Puncture Proof Tubes. Helium gas instead of air can be used economically in the huge tyres of Convair’s 204 passenger Model 37 airliner to save weight, it was disclosed recently by Consolidated Vultee engineers. Air required to fill the tyres would weigh 180 pounds compared with 26 pounds for helium. Tests have proved that the puncture proof tubes will hold the lighter helium gas at the required pressure. The 154 pounds saved by using helium means that extra payload can be carried, with increased revenue to the operator. Because of the diminishing earthward pull of gravity with increased altitude, the 160 ton airliner will weigh 745 pounds less at 25,000 feet altitude than on the ground.
