Abstract

PURPOSE:To make a mobile operation for a helicopter on land easy by arranging an installation unit to install helicopter carrier wheels in an alighting skid so as to connect and disconnect freely in an alighting gear having alighting skids protruding downward from its airframe. CONSTITUTION:An industrial radio control unmanned helicopter has a long and narrow airframe 2 extending in the forward and backward direction, and paired front and rear support legs 3 extend respectively from each right and left side part to the front part lower surface of this airframe 2, and alighting skids 4 are supported respectively with each support leg 3. Here, the front part of each alighting skid 4 is bent in the forward and upward direction, and on that front edge, a hook shape installation unit 13 is formed so as to open in the downward direction. On the one hand, a wheel 14 to carry the helicopter 1 is prepared beforehand, and this wheel is constituted from paired right and left wheel bodies 14a and an axle shaft 14b to connect the paired right and left wheel bodies 14a with each other so that this wheel 14 can be connected to and disconnected from the installation unit 13 and the helicopter can be moved under a condition that the tail part of the airframe 2 is hoisted.
