PROBLEM TO BE SOLVED: To stably and surely recover an aircraft without having impact on an aircraft regardless of kinetic energy of the aircraft during landing.SOLUTION: A recovery system 120 includes: an engagement part 150 provided rotatably on a horizontal surface to make a looking part engaged with so as to brake an aircraft in engagement with a hooking part 138 provided in an aircraft 110; a rotation detection part 152 for detecting a value resulting from rotation of a rotating shaft 150b of the engagement part; a rotor 154 provided in the rotating shaft of the engagement part and composed of one or more blades 154a; MR fluid 156 filled in a container 156a to come into contact with the blades of the rotor; a magnetic field application part 158 for applying a magnetic field to the MR fluid; and a system control part 160 for changing the magnetic field so as to make a detection result of the rotation detection part approach a target value. |
