Abstract This paper introduces the current situation of verticality adjustment launch vehicles at home and abroad, analyses problems risks existing in abroad. A new scheme for vertical a vehicle is proposed this paper. The compares old schemes with actual application certain type vehicle. cancels level measuring instrument on rocket, simplifies operation rocket launching site, reduces design re...

This work is an example of application of nonlinear programming to a problem of three-dimensional trajectory optimization for multistage launch vehicles for geostationary orbit missions. The main objective is to minimize fuel consumption or equivalently to maximize the payload. The launch vehicle considered here, Europa-II, consists of 5 thrust phases and 2 coast phases. Major parameters of the...

Vibrations of launch vehicle conical fairings are investigated. Fairings simulated using thin conic shells. The modal analysis a elastic shell is based on the use developed finite element model an inhomogeneous shell. In general, technique makes it possible to investigate geometrically nonlinear deformation, stability, and post-buckling behavior wide class structure implemented at each step sta...
