摘要

PURPOSE: A multi-purpose unmanned aircraft for local monitoring, taking pictures, watching and communication is provided to promote long-time specific local monitoring and watching impossible for an airplane or a helicopter by improving the structure for vertical rising and falling as well as flight at a standstill. CONSTITUTION: An unmanned aircraft(1) is fixed as each ring hinged from a foothold portion in the center of a truck is connected to four hooks under the aircraft. To launch the unmanned aircraft, a worker unlocks the four hooks from the rings of the foothold. Then, the worker sets a multi-step aircraft control switch on a control console to a lower step of falling and turns on a power switch. A motor(3) of the unmanned aircraft is driven and blades(2) connected to the motor are rotated at the minimum speed. The rotation speed of the blades rises up slowly when the worker changes the multi-step aircraft control switch to a higher step of rising from the lower step of falling. The lift force of the unmanned aircraft rises up gradually and the unmanned aircraft is lifted vertically. In addition, the unmanned aircraft can fly at a standstill when the control switch is fixed by a locking bar at the desired height. The unmanned aircraft is useful for long-time local monitoring, taking pictures and watching. Therefore, the unmanned aircraft promotes the maximum efficiency and good points in cost to effect.
