A system is disclosed for lifting a rocket into the upper atmosphere and
establishing forward flight at several hundred miles per hour, before the
rocket engines are ignited and the rocket is released from the lifting
system. The main subassemblies of this lifting system comprise: (1) an
array of large helium-filled dirigibles, of a size that can provide
hundreds or thousands of tons of lifting force; (2) a tank-holding
assembly that will be tethered to the dirigibles, and that will contain
pumps and high-pressure tanks, to recapture and store the helium for use
in subsequent launches; and, (3) a winged platform, with wings that can
be rotated vertically during liftoff, and horizontally to establish
forward flight after a desired altitude has been reached, and having
conventional aircraft engines on each wing. This system enables safer,
less expensive, and more efficient launching of rockets and heavy
payloads into space, using easily reusable subassemblies.
