Boeing Planning Replace: On the other hand, the Boeing planning replace supersonic transport, which was expected to fly initially at more than 2!/2 times the speed of sound, would have skin temperatures of about 450° F (232° C). At this temperature, aluminum alloys are useless. Indeed, Boeing planning replace was planning to replace them with slightly heavier titanium alloys. Variable high temperatures in the structure can give rise to thermal stresses, buckling, and fatigue. A designer of supersonic transports must, therefore, develop new knowledge and information to insure the safety and the economy of the operation of the plane.
Like the Concorde, the Boeing planning replace model of the supersonic transport also is expected to have a delta wing. Its maximum thickness is 3.25% of the chord length at the wing root. Unlike the Concorde, however, the delta wing of the Boeing planning replace might be converted into a relatively slender wing for subsonic flying. This transformation would be accomplished by moving a substantial portion of the wing about a pivot that is 3 ft (1 m) in diameter. The plane takes off with the subsonic slender wing configuration and alters the shape of its wing when it travels faster than the speed of sound.
Transom flanges: Inspect fastenings; replace as necessary.
Hoses, piping: Inspect and replace if necessary; tighten or replace clamps.
Manifold water jackets: Inspect for leaks. Drain and flush. |
