ABSTRACT:
An improved multistage launch vehicle provides a redundant stage wherein, for N stages in total, N-1 stages will suffice to lift the payload into earth orbit. At least two of the N stages are ignited in parallel at lift off. Interstage coupling and payload stage coupling mechanisms allow the successful completion of the mission and lifting of the payload into orbit irrespective failure of a stage. Interstage propellant transfer is provided to increase efficiency of the parallel stages and allow the increased thrust of parallel ignition at lift off.
