Embodiment 1
[0020] In this embodiment, the steps adopted include the following for the turning needs in any situation:
[0021] 1) The aircraft flies horizontally and reaches the sky above the mission waypoint that needs to turn. At this time, the mission waypoint is the current position.
[0022] 2) The aircraft changes from a horizontal flight attitude to a vertical flight attitude. The propellers on both sides are linked to control the tension, and the ailerons on both sides are linked to lift the nose of the aircraft. The speed of the propellers on both sides is adjusted. Adjust to vertical flight attitude.
[0023] 3) For the aircraft in the vertical flight state, the direction of the belly deflects, and the differential ailerons on both sides make the aircraft rotate around the axis, so that the aircraft rotates along the axis of the belly, and stops rotating when the belly is in line with the direction of the mission route , to keep the aircraft in vertical flight.
[0024] 4) Th...
Embodiment 2
[0028] When the aircraft performs parallel-spacing routes such as surveying or spraying pesticides, the target route is the established route
[0029] Step 1) The aircraft flies horizontally over the mission waypoint that needs to turn, and the aircraft cannot fly directly to the mission route. Therefore, at this time, the mission route must intersect the turning radius of the aircraft. At this time, the aircraft still faces the task with the minimum turning radius. The mission waypoint is the intersection point of the turning radius and the extension line of the mission route.
[0030] Step 2) When the aircraft reaches the mission waypoint, the flight attitude of the aircraft gradually changes to the vertical flight state.
[0031] Step 3) When the aircraft is in the vertical flight state, the direction of the belly of the aircraft is deflected to the direction of the mission route, and the deflection is stopped when the direction of the belly of the aircraft is consistent wi...
Embodiment 3
[0036] In this embodiment, the target route deflects, such as some tracking tasks, the direction of the target’s movement changes, and the angle between the original route and the original route is an arbitrary angle. Fly at the extension line of the mission route where the mission is to be executed. The mission waypoint is the intersection point of the turning radius and the extension line of the mission route. After determining the mission waypoint, continue to execute according to step 2).
[0037] It is worth noting that due to the continuity of the aircraft's movements, the schematic diagram of the turning attitude adjustment in this application is only used to illustrate the changes of the aircraft's movements, and does not strictly represent the flight position and state.
