What does drone headless mode mean?

During the flight, if the geographical coordinate system is taken as the reference coordinate system, the plane will fly in headless mode. Headless mode is more common in multi-rotors, such as four-axis and six-axis aircraft.

Any plane must have its own coordinate system, that is, the head and tail of the plane, that is, the plane's own coordinate system mentioned above. If you press the remote control to fly forward, the plane will still fly in the direction indicated by the nose when taking off. Even if the plane changes the direction of the nose during flight (manipulating the heading angle of the remote control), the plane will run in headless mode.

Performance index of UAV

1, range: an important indicator to measure the combat distance of unmanned aerial vehicles. It is related to the airfoil, structure and power plant of UAV. In addition, the US military has been studying the aerial refueling technology of unmanned aerial vehicles to increase the range of unmanned aerial vehicles.

2. Endurance: an important indicator to measure the continuity of UAV mission. Different types of UAV systems have the same requirements for battery life. The time that an aircraft can continue to fly after running out of available fuel is called the maximum endurance.

3. Upper limit: The maximum flying height that an aircraft can keep level flight is called the upper limit, which is divided into theoretical upper limit and service upper limit. Flight altitude is an important index for military aircraft to ensure the completion of combat tasks.

4. Flight speed: Flight speed is an important data to measure the flight ability of UAV, even the penetration and attack performance, including cruising speed and maximum speed. Cruise speed refers to the horizontal flight speed of the aircraft in the cruising state, which is generally 70% ~ 80% of the maximum speed.

5. Climbing rate: the height that the aircraft rises in unit time under certain flight weight and engine working conditions. It can also be expressed by how long it takes to climb to a certain height.
