Problems solved by technology

However, limited by the energy density of lithium batteries and the structural weight of the aircraft, the lithium batteries carried on the quadrotor aircraft are limited, and because the energy storage of lithium batteries is its only energy source, the flight time of the quadrotor aircraft will inevitably be affected.
The short time to stay in the air has become the fatal weakness of the quadrotor aircraft

Embodiment Construction

[0049] Combine below figure 1 , 2 , 3 a kind of day tracking type solar quadrotor aircraft can be further explained to a kind of in the present invention:

[0050] The present invention provides a design scheme of a novel four-rotor aircraft capable of tracking the day and making full use of solar energy to realize long-time flight in the air, such asfigure 1 As shown, the solution is to install the sun tracking sensor 7 at the four rotor intersection points (ie, the central position) of the conventional quadrotor aircraft (including the motor 1, the propeller blade 2, the frame 3 and the controller 4) to measure the sun in real time. Azimuth: A two-axis motor 5 and a rotatable solar cell module 6 are installed at the midpoint of the four sides formed by the four rotors, and the measurement angle of the tracking sensor is used as the target point. The use of the two-axis motor can realize the one-time rotation of the solar battery module to the best position, which can not on...

Abstract

The invention provides a design scheme of a sun-tracking solar quadrotor aircraft. The design scheme applies a sun-tracking mechanism and a solar cell module capable of two-axis rotation to a traditional quadrotor aircraft. Using the tracking sensor and the real-time adjustment of the motor, the solar cell module can supply energy for a long time and output solar energy to the maximum extent. This solution can solve the fatal flaw of the traditional quadrotor aircraft, which is short in the air, so that the application advantages of the quadrotor aircraft can be fully utilized. At the same time, the use of two-axis motors can realize the solar cell module to rotate to the best position at one time, thereby saving the energy of the quadrotor aircraft system. The application of the maximum power tracker can make the solar cell module always work at the maximum power point, and then the maximum Maximize the use of solar energy.

Description

[0001] 1. Technical field: [0002] The invention provides a design scheme of a sun-tracking solar quadrotor aircraft, which belongs to the technical field of aerospace vehicle energy systems. [0003] 2. Background technology: [0004] The quadrotor aircraft uses four rotors as the direct power source for the flight. The rotors are symmetrically distributed in the front, rear, left and right directions of the body. The four rotors are on the same height plane, and the structures and radii of the four rotors are the same. The rotors rotate in the same direction, one group rotates clockwise, and the other group rotates counterclockwise, so that the counter torque of the rotor to the fuselage can be balanced. The four motors are symmetrically installed on the bracket end of the aircraft, and the flight control computer and external equipment are placed in the middle space of the bracket. The quadrotor aircraft can hover freely and take off and land vertically, and has a simple s...
