Abstract
An unmanned aircraft which has uniform lift and the overall airframe dimensions of which can be made small is disclosed. This unmanned aircraft is provided with four propeller shafts jutting horizontally along diagonals from the airframe, and four propellers constituted from twin blades having folding mechanisms. Engine rotation is transmitted to the propellers by gears. The unmanned aircraft features that all of the propellers are at the same height from the tip end of the propeller shafts; the rotational ranges overlap those of the neighboring propellers; the mounting angles are set 90 degrees off from those of the neighboring propellers; and the rotational directions are mutually opposite from those of the neighboring propellers.
