BUZZ KIDS DROENS

  forward from BUZZ KIDS DRONES -------The flying principle of drones    The  rotor , like the wheel, is a magical invention, which brings us more possibilities to explore the sky. The quad-rotor  UAV  has been turned into an aerial camera, which satisfies many ordinary people’s imaginations about the sky.   The reason why the rotor can fly is that the rotor provides an upward force for the load.   People who have played with bamboo dragonfly should know that: when the hand rubs the bamboo dragonfly a rotation speed, it will generate lift force to make the bamboo dragonfly take off.  In the same way, the multi-rotor UAV is also driven by the rotation of the motor, which causes the propeller to generate lift. For example, a four-rotor UAV, when the sum of the lift of the four propellers of the aircraft is equal to the total weight of the aircraft, the lift of the aircraft is balanced with gravity, and the aircraft can hover in the air.   According to  Newton's third law , while the

    The word " drone " seems to be very big, but in modern society, it has penetrated into all aspects of people's lives.     Whether it is military, agricultural, or industrial drones, they can make their own contributions in areas where manpower cannot be used well.      With people's use of UAVs and the broadening of usage scenarios, the requirements for UAV performance are getting higher and higher.      So, for civilian drones (with a flight time of less than 30 minutes), maintaining a flight time of more than ten to twenty minutes requires a battery with a larger volume and weight, which will undoubtedly affect the overall weight and volume of the drone.     So, people will have this question, why the battery of mobile phones can be compact and long-lasting, some mobile phone batteries can even be used for more than a few days, why can’t the batteries of drones be compact and long?      How about time usage, even after a short flight, the charging time required
