Abstract

A rocket launch vehicle comprising a rocket body having a forward section and an aft section, a first rocket engine fixedly mounted to the aft section of the rocket body and axially aligned with the rocket body, a second rocket engine detachably mounted to the aft section of the rocket body and aligned axially parallel with the first rocket engine, a third rocket engine detachably mounted to the aft section of the rocket body and aligned axially parallel with the first rocket engine and being on the side of the first rocket engine opposite the second rocket engine, a first recovery structure fastened to the second rocket engine, a second recovery structure attached to the third rocket engine, and a plurality of propellant supply tanks connected to the first, second, and third rocket engines. Each of the rocket engines is a Space Shuttle main engine. The propellant tanks are detachably mounted to the exterior of the rocket body. Fuel tanks are affixed to the interior of the aft section of the rocket body and communicate with the first rocket engine. The recovery structure includes a parachute deployment arrangement for selective deployment of a parachute within a reentry vehicle fixedly attached to each of the second and third rocket engines. The forward section of the rocket body is a modified Titan 4 payload fairing.

Dependent claims

A method of launching a rocket vehicle having one fixedly mounted rocket engine and two detachable mounted rocket engines affixed to a structural base member, having a plurality of propellant tanks demountably fastened to the exterior of said rocket vehicle forward of said structural base member, having fuel tanks fixed to the interior of said rocket vehicle, and having a payload fairing in the forward portion of said rocket vehicle, said method of launching comprising the steps of:

igniting said fixedly mounted rocket engine and said detachably mounted rocket engines;
passing propellant to said engines from said plurality of propellant tanks until said rocket vehicle achieves a desired altitude;
stopping the passage of propellant between said propellant tanks and said two detachably mounted rocket engines such that said detachably mounted rocket engines are shut down;
detaching first each of said detachably mounted rocket engines from said rocket vehicle such that each of said detachably mounted rocket engines drop from said rocket vehicle, said step of detaching further comprising:
securing the detached rocket engines within a reentry vehicle, said reentry vehicle being a structural member having atmospheric shielding capabilities for protection of said rocket engine, said reentry vehicle having a parachute deployment section arranged therein;
demounting second said plurality of propellant tanks from the exterior of said rocket vehicle such that said plurality of propellant tanks drop from said rocket vehicle;
and
passing propellant from said fuel tanks to said fixedly mounted rocket engine, said propellant from said fuel tanks sufficient to allow said rocket vehicle to achieve an orbit.
