UAVs are more and more widely used in military and civilian applications. In order to make UAVs play a better role, it is necessary to use multi-UAV formation flight control to achieve tasks such as coordinated reconnaissance,drone support   combat, defense, and pesticide spraying.

The multi-UAV cooperative formation control technology mainly includes information perception technology, data fusion technology, task allocation technology, track planning technology, formation control technology, communication networking technology and virtual/physical verification experiment platform technology.

Firstly, the current status and progress of related technologies of multi-UAV formation at home and abroad are reviewed, and then the control method of multi-UAV formation is analyzed, and the problems of formation design, formation adjustment and formation reconstruction are summarized. Finally, the opportunities and challenges faced by the multi-UAV cooperative formation are prospected.

1. Always check the tension of the saw chain. When checking and adjusting, please turn off the engine and wear protective gloves.chainsaw chain   When the tension is suitable, when the chain is hung on the lower part of the guide plate, the chain can be pulled by hand.

2. There must always be a little oil splashed on the chain. The chain lubrication and oil level in the oil tank must be checked every time before work. Chains must not work without lubrication, as working with dry chains will result in damage to the cutting device.

3. Never use old oil. Old oil cannot meet the lubrication requirements and is not suitable for chain lubrication.

4. After replacing and installing a new chain, the saw chain needs 2 to 3 minutes of running-in time. Check chain tension after break-in and readjust if necessary. A new chain requires more frequent tensioning than a chain that has been used for a while.
