Abstract
BISPLINGHOFF has given a comparative graph showing the relative importance of the parameters of design at various Mach numbers. At Mach numbers above five, i.e. in the range of missile flight, creep becomes the critical design factor. Even though the time of flight of the missile is very short, and not enough to cause any considerable amount of creep, the deflexions caused will be enough to disturb the stability of compression members. Also the aerodynamic shape can be distorted with serious effects on the flow characteristics of the profile.
