The invention relates to a long-cylinder parking rack for aircrafts on an aircraft carrier. The long-cylinder parking rack comprises a rack body (1), a shaft seat, a motor and a transmission device. When the rack body (1) rotates, the parked aircrafts are prevented from rolling; the gravity moment of the rack body (1) is zero, and the gravity moment of the parked aircrafts is counteracted; the dynamic moment required for the rotation of the rack body (1) is relatively small, thereby remarkably saving energy; the aircrafts can be quickly parked in and picked up from the rack body (1) in batches; and after the aircrafts are parked in the rack body (1), air in the aircraft parking space is purified immediately, thereby maintaining aircraft bodies, engines and electronic components in time, and prolonging the service life of the aircrafts.
