Three-axis aircraft and moving and taking off method

Abstract

The invention provides a three-axis aircraft with high maneuverability. The three-axis aircraft comprises a fuselage, rotors and a power device driving the rotors to rotate. The rotors include the first rotor, the second rotor and the third rotor. The first rotor and the second rotor are symmetrically mounted on the two sides of the fuselage and near the front end of the fuselage. The third rotoris mounted at the position near the back end of the fuselage. A deflection driving device is mounted on the fuselage to drive the third rotor to obliquely rotate around the axis of the length direction of the fuselage. The first rotor and the second rotor have the same diameter, and the diameters of the first rotor and the second rotor are greater than the diameter of the third rotor. The maneuverability of the three-axis aircraft is advantageously improved.

Description

technical field [0001] The invention relates to a multi-axis aircraft, in particular to a high-maneuverability three-axis aircraft and a mobile take-off method. Background technique [0002] A multicopter usually includes a fuselage, an arm, a flight control device, a power supply, an ESC, a drive device, a rotor and functional sensors. The drive unit that drives the rotor to rotate can be a motor, an oil engine or a power unit with a speed changer. The power plant of some aircraft is connected with the differential gear input shaft, and the two output shafts of the differential gear are respectively connected with a rotor. A power unit can be used to drive two rotors to rotate through a differential. [0003] The announcement number is CN105059558A, which discloses a take-off and landing system for unmanned ship-borne UAVs. for multicopters. In a suitable airflow environment, cancel the electromagnetic force between the unmanned ship and the UAV, and release the UAV. I...

AI Technical Summary

Problems solved by technology

[0004] Existing multi-axis aircraft basically only adjust the flight attitude by changing the rotor speed. Translational flight needs to tilt the fuselage, thus increasing the windward area of ​​the fuselage, resulting in an increase in flight resistance, making the multi-axis aircraft slow in response and poor in maneuverability , the frequent acceleration and deceleration of the motor causes a large loss of kinetic energy, large heat loss of the motor, and low efficiency

Under the action of high-speed airflow, it is difficult to take off and land safely

Before taking off on the high-speed mobile platform, the multi-axis aircraft has no protection measures, not only is it easy to be blown off by the high-speed airflow, but also cannot achieve safe and stable mobile take-off and landing
