Two-stage reusable carrier

A two-stage reusable carrier comprises a first sub-stage and a second sub-stage which are connected in series. The first sub-stage is an axisymmetric thin-wall cylindrical rocket body and is provided with canards, lift wings and V-shaped empennages; the lifting wings are fixed wings, are positioned at the rear part of the rocket body, adopt delta wing forms and provide lifting force or resistance for a sublevel in the horizontal return process, and the lifting ailerons are arranged below the wing bodies and can be used for steering or vertically yawing; the canard is a single-shaft swing wing, and a rotating shaft is parallel to the rocket shaft and located at the front part of the rocket body; the V-shaped empennage is a fixed wing, is positioned at the rear part of the rocket ground and adopts a symmetrical double-empennage form; the second sub-stage is an axisymmetric thin-wall cylindrical rocket body, and the layout scheme is similar to that of the first sub-stage. The invention provides a design scheme f
