Abstract:
종래의 하방날개형 비행체는 프로펠러의 회전으로 발생하는 비행체의 반토크를 제거하고 비행체의 비행을 위해, 여러 쌍의 고정판과 전후진 조정날개 및 좌우회전 조정날개를 각각 장착하여 조정함으로 비행체의 구조와 조정이 복잡하며 비행체의 무게와 부피가 대형화하게 되어 협소한 공간에서 정찰 및 감시에 어려운 문제점이 있었다. 그러나, 본 발명은 비행체의 반토크를 제거하지 않고 1개의 조정날개로 비행체가 계속하여 회전하면서 정지, 전후진, 좌우회전, 좌측진, 우측진 등의 비행을 가능하게 한 것을 특징으로 하는 비행체로서, 비행체의 구조와 조정을 간단하게 하여 무게와 크기를 줄일 수 있어 협소한 장소에서의 비행 뿐 만아니라, 실내에서의 정찰과 감시 등을 가능하게 하고, 동력효율을 높일 수 있는 회전하는 하방날개형 비행체를 제공한다. 고정피치, 가변피치, 프로펠러, 고정판, 조정날개, 카메라
Abstract:
PURPOSE: A three bottom-blade vehicle is provided to improve power efficiency and length the flying duration, and to reduce the affects of wind by securing enough distance between the rudders. CONSTITUTION: A fixed-pitch propeller(2) is horizontally installed around a central shaft(1). A power unit(3) is installed on the top of the central shaft of the propeller. A control unit(4) is installed on the bottom of the central shaft of the propeller. One end of each of first to third attachment plates(11~13) is successively attached to the control unit at the angle of 120 degrees. The other end of each attachment plate is attached to a round frame(5) and leg plates(32,33).
Abstract:
A dual ducted fan arrangement in which the duct components (203), engine (10), and avionics/payload pods (300, 302) are capable of being quickly disassembled to fit within common backpacking systems. Each duct is identical in fan (201), stator (102), and control vane design. Assembly connections between ducted fans (203) and electronic modules are also identical. An engine (10) or APU drives the dual ducted fans (203) through a splined shaft (601) to a differential (600) or through electric motors. Energy is transferred to the ducted fans by a single gear mounted to the stator (102) hub. Relative speeds of the individual ducted fans are controlled through separate frictional or generator load control braking mechanisms (603) on each of the splined shafts (601) between the differential (600) and ducted fans (203). In the electric motor case relative speed is through electronic speed control. The fans (201) are counter rotating for torque balancing. The electronic module locations are vertically variable for longitudinal center of gravity for variations in payloads.

Abstract:
Disclosed is an unmanned aerial vehicle take-off and landing control system and a control method. The control system comprises a magnet assembly provided at the side of an unmanned aerial vehicle (1) and a magnetic field assembly provided at the side of a parking platform. An electrified coil (2) is provided in the magnetic field assembly. A current is supplied into the electrified coil (2). A supporting magnetic field is generated by the magnetic field assembly at the side of the parking platform, so that a thrust force acting on the unmanned aerial vehicle (1) is formed. A resultant force is formed by the thrust force and a lift force or resistance force in the process of take-off or landing of the unmanned aerial vehicle (1) to supplement the lift force or the resistance. In the process of take-off or landing of the unmanned aerial vehicle (1), the current in the electrified coil (2) is changed to form a uniform magnetic field, the thrust force acting on the unmanned aerial vehicle (1) is generated to supplement the lift force or the resistance in the process of take-off and landing , thereby improving the safety performance of the unmanned aerial vehicle (1), reducing the energy consumption of the unmanned aerial vehicle (1) when it is used, and prolonging the service life of the unmanned aerial vehicle (1).
