Abstract:
PURPOSE: A driving apparatus and an air vehicle are provided to make a flying object fly upward, downward, frontward and backward freely by realizing the motion of a bird or an insect's wings. CONSTITUTION: A flapping apparatus(300) and a lagging apparatus(400) comprise driving arms, rotors, piezoelectric actuators, housings, insertion grooves and guide slots respectively. The driving arms generate flapping or lagging displacement by adding force to the end of blades. The rotors rotate the driving arms vertically or horizontally. The piezoelectric actuators rotate the rotors by forming driving grooves in the rotors and inserting in the driving grooves. The housings store the rotors. The insertion grooves are formed in the housings to insert the piezoelectric actuators. The guide slots guide flapping or lagging movement passages of the blades by the driving arms. Thereby, an airplane to be freely flown upward, downward, frontward and backward is realized.
Abstract:
PURPOSE: A VTOL(vertical takeoff or landing) aircraft by using a variable vane system is provided to control the yaw of a fuselage by offsetting torque from a propeller with plural variable yaw vanes and adjusting the angle of the vane, and to adjust pitch and rolling by using the drag with operating pitch and roll vanes. CONSTITUTION: A VTOL(vertical takeoff or landing) aircraft is composed of a propelling system having a propeller(1) and an engine(2); a torque control unit having a fixed yaw vane(3) and a variable yaw vane(4) installed in the lower part of the propeller to control yawing of the fuselage; a front pitch vane(5) and a rear pitch vane(6) controlling the direction of the fuselage pitch; a right roll vane(7) and a left roll vane(8) controlling rolling of the aircraft; and a duct(9) surrounding the propeller. Torque from the propeller system and yawing of the fuselage are controlled with the fixed yaw vane and the variable yaw vane. The size of the fuselage is reduced by eliminating a tail rotor from the yaw vane system, and breakage of the aircraft is minimized against collision. The structure is simplified, and maintenance is conveniently performed by using pitch and roll vanes. The performance of the propeller is improved with protecting the propeller by the duct.

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.
