The Issues Faced in Drone Use
The more prevalent use of drones has made unmanned aircraft a common sight in the skies today and they are widely claimed to be what will drive big changes in how we live our lives. Yamaha Motor’s work in the unmanned aircraft field began in the 1980s with the development of an industrial-use unmanned helicopter aimed at bringing greater automation and labor savings to Japan’s agriculture industry. Today, Yamaha’s helicopters play an important role in aerial crop dusting as well as professional surveying and surveillance operations.
Recent years have seen a rapid growth in drone use across a wide range of jobs, and battery-powered models are the mainstream choice due to their ease of operation and relatively low purchase and introduction cost. Another reason driving the spread of drones lies in the advantages provided by their electric motors, such as instant delivery of strong torque, excellent response and highly controllable power.
However, there are tasks that require a full day’s worth of flying and this inevitably entails battery swaps. This in turn means operating a drone comes with limitations that must be taken into account, such as a work environment where recharging can be done and allowances for charging time. In short, if you want longer range and flight time, you have to increase the capacity of the battery.
However, that will naturally make the battery bigger and heavier, introducing a new problem of adding onto the overall weight of the aircraft. This presents a dilemma for drones that fly only on the power of the battery and motor—enlarging the power source does not necessarily bring a proportionate increase in range, flight time and payload.
So, how you get that power becomes key.
