Abstract:
PURPOSE: A pressure sensor is used to measure pressure difference between both wings of an airplane, thereby measuring position angle of the wings. CONSTITUTION: More than two pressure measuring members(10) are installed in both wings of an airplane through atmosphere connection pipes(2,3). A loaded computer(4) is installed to calculate position angle with the measured pressure of the pressure measuring members.
Abstract:
PURPOSE: A power supply system for an electric aircraft using a rotary power supply line is provided to reduce the weight of an electric aircraft and to increase the electric aircraft to a constant altitude with external power by supplying power to the electric aircraft through a rotary power supply line. CONSTITUTION: A power supply system for an electric aircraft using a rotary power supply line comprises a lifting support(100), a winding device(200), a power supply unit(420), a power charging unit(510), and a ground control unit(600). The winding device is coupled to the lifting support to ascend and descend. The power supply unit is coupled to the winding device to supply power to an aircraft. The power charging unit is installed in the aircraft and is connected to the power supply unit to receive the power. The ground control unit controls the winding device and the power supply unit.
