This paper describes a method for the determination of the flexible modes of an air-breathing hypersonic vehicle. The method outlined here takes into account changes in vehicle mass and structural temperature over the duration of the vehicle's trajectory. A simple sizing program is outlined to estimate the vehicle volume, mass, and planform requirements for a dual-cycle (rocket and scramjet) powered vehicle. It is shown that the varying mass effects dominate the frequencies and mode-shapes over the structural heating effects. We then discuss the effects of the structural modes on the transmission zeros.
