The use of a multistage gearbox in an electric drive on quadcopters

The purpose of the work is to develop a multistage gearbox for quadcopters with an additional mass of approximately 700 g, for example: a topographic camera, a small parcel, or, as in the case under consideration, anti-radiation protection and a sensor for measuring radiation levels. We will develop such an electric drive that will ensure the preservation of maximum speed and maximum speeds of climb and descent, as well as select a new battery to preserve such characteristics as maximum range and altitude, maximum flight time and maximum hover time. The article discusses the main stages of selecting the components of an electric drive, taking into account their mass in the required thrust, to ensure the functioning of an average quadcopter upgraded for the study of a radiation-contaminated area. An example of solving the problem of insufficient traction of electric drives is considered. Comparing the use of a multistage drive with the traditional use of an engine without a gearbox on quadcopters, it is worth noting that a multistage drive is more technologically expensive, as well as has a large mass, but at the same time it provides higher useful thrust than most engines used on modern quadcopters. Also, the advantage of the developed drive is the protection of the motor board from radiation by the housing and gearbox, which increases the service life of the quadcopter in the conditions under consideration.
