Abstract: An aircraft having propulsion units for both conventional aircraft flight in the atmosphere and for high-altitude operation as a rocket. The aircraft is divided into a payload compartment and a compartment containing rocket propulsion unit propellant or fuel, and includes a long transverse wing with a small back-sweep to favor lift in the dense layers of the atmosphere and to thus make it possible to climb to high altitudes at a subsonic speed before using the rocket propulsion units. The return flight portion is performed by gliding or controlled as for a conventional aircraft.

Abstract: This aircraft comprises both propulsion units (7, 16, 17) for conventional aircraft flight in the atmosphere and for high-altitude operation as a rocket. It is divided into a payload compartment (8) and a compartment (13) essentially containing rocket propulsion unit ergols. It comprises a long transverse wing (3) with a small back-sweep to favour the lift in the dense layers of the atmosphere and make it possible to climb to high altitudes at a subsonic speed before using the rocket propulsion units. The return is performed by gliding or controlled as for a conventional aircraft.
