Design and Implementation of On-board Hybrid Generator for Rotary Wing Drone

Drone which power up with Lithium Polymer (LiPo) battery doesn't have long duration flight time. The average enterprise-class rotary wing drone that weighs more than 10kg has a flight duration of less than 20 minutes. By developing an on-board generator system, it is expected that flight time of enterprise-class drone increase significantly. This development has many challenges such as the output of generator must have a large amount of power, the system needs a battery as fail-backup system so the charging system must be developed. The weight of developed system is one of consideration whether this system can be used as an on-board system or not. This paper discuss how the process of power generation that used by propeller done and how charging system work with Lithium Polymer.
