Abstract : In the report an analysis yielding the modal responses of a rocket, constrained or in free flight, is presented. The effects of a tangential end thrust are considered as are the influences of shear and structural joints. The modelling was accomplished by employing the finite element technique. The resulting program, called Vibration Analysis of an Axially Loaded Rocket (VAALR), is discussed and a section on user procedures is included. Examples are offered to aid the engineer in data card preparation. The results of parameter studies are considered to offer some suggestions in modelling. Among the parameter studies is an analysis of the THAD T-6 missile. (Author)
