FASTER PLANES
, NEW METAL EVOLVED WASHINGTON. The United States Navy has developed a new liglit-weight metal which will enable jet planes to climb faster and fly further. Idle new metal, developed by the Navy Bureau of Aeronautics, is a liglit-weight titanium alloy, as strong as high-strength steel but only hall as heavy, the Defence Department said.- It is already being used in parts of new jet planes where strength at high temperatures is of major importance. These include turbine blades, tailpipe shrouds, engine firewalls ana in tlie engine itsef. Other metals now in use including aluminium and magnesium, do not retain their basic properties at high temperatures. The new alloy, composed basically of 5 per cent, chromium, 3 per cent, aluminium and the remainder titenium, possesses the advantageous physical properties of several metals now in use. The Defence Department said use of the new alloy would make possible improvement of several flight characteristics, including rate of climb, range, payload and manoeuvrability. Titanium ores are available in large quantities in both the United States and Canada. —Reuter.
