This paper investigates the dynamical behavior of an assembled beam like structure with tip masses as a model of a two stage rocket. The beam like structure is composed of two different beams connected together carrying two tip masses at the ends for modeling the warhead and the nuzzles. The...

The concept is comparable to Falcon 9, but it relies on a two-stage system, the first one of its kind. Its design puts the payload inside the “belly” of stage 1, while the second stage is located inside the rocket, exposed by opening the payload fairing. ...
