1. An inflatable wing for a rotary-wing aircraft, the inflatable wing comprising: a wing part configured to be installed on a fuselage of the rotary-wing aircraft, wherein the wing part includes a main wing having a predetermined width and a predetermined length, an aileron extended from the main wing in a width direction of the main wing, and a moving guide part provided in the main wing to guide an expansion of the main wing and provide a support force to the wing part; andan air supply part including an air supply apparatus, the air supply apparatus being configured to inject air into the wing part and discharge the air from the wing part,wherein the wing part is configured to be installed on the fuselage along a width direction of the main wing, and the main wing and the aileron are configured to be expanded in a length direction of the main wing by the moving guide part when the air is injected into the wing part by the air supply apparatus. 2. The inflatable wing of claim 1, wherein the wing part further includes an air inlet through which the air is injected into and discharged from the main wing and the aileron. 3. The inflatable wing of claim 2, wherein the air supply part further includes an air supply pipe having one side communicating with the air supply apparatus and the other side communicating with the air inlet of the wing part. 4. The inflatable wing of claim 1, wherein the aileron is comprised of a first aileron linked with the main wing and a second aileron linked with the first aileron, the first aileron is injected with the air independently from the second aileron, and the second aileron has pneumatic coupling with the main wing. 5. The inflatable wing of claim 4, wherein an angle formed by the second aileron and the main wing is controlled depending on an amount of the air injected into the first aileron. 6. The inflatable wing of claim 1, wherein the moving guide part includes a fixing guide provided at a center of the main wing and moving guides provided on both sides of the fixing guide.
