1. A wing system, comprising:
a stowable aerodynamic wing structure configured to be rolled and/or folded,
the wing structure comprising spars having a plurality of pressure chambers made of a flexible material, which extends along a span width of the wing structure, and
a tear-resistant outer skin fabric, which encases the wing structure,
wherein the pressure chambers are arranged extending adjacent to one another and/or one over another in a filled state;
wherein the pressure chambers of the wing structure are fillable with a liquid, and the wing system comprises a pump system, wherein the liquid is held at pressure over 50 bar in the pressure chamber; and
wherein the pressure chambers are connected to one another with bracing threads to increase dimensional stability of the wing structure.
