Al-Li alloys and ultrahigh-strength steels for U. S. Navy aircraft
- Naval Air Development Center, Warminster, PA (USA)
An evaluation is made of the development status and prospective performance advantages and cost reductions obtainable through the application of state-of-the-art Al-Li alloys to naval aircraft airframes and ultrahigh strength Ni-Co alloy steels to their landing gears. Structural weight fractions are expected to be reduced by 8-10 percent through substitution of high-stiffness Al-Li for conventional Al alloys. Ni-Co alloy steels enhance landing gear damage tolerance and resistance to environmental degradation, without associated weight penalty, when supplanting conventional low-alloy steels. Both materials are judged ready for immediate application to existing and next-generation U.S. Navy aircraft. 8 refs.
