AUTONEWS
A team of engineers from Flowcopter (Scotland) is building a high-capacity, heavy-duty drone powered by a Rotax main engine that drives four main hydraulic motors. Already during the first test flights it became clear that he could lift a weight of around 100 kg without any problems.
In the future, Flowcopter production models will deliver a payload of up to 150 kg over a distance of up to 900 km, thus forming a new "ultra-long" niche of UAVs, which, for example, will be involved in transporting cargo to remote settlements, to offshore oil platforms or participate in search and rescue operations.
Participation in the Rotax aircraft engine is not accidental - drones with electric motors will not be able to handle such loads. However, ICE also has its own problems. One is the difficulty in instantly adjusting the torque to balance the drone in flight.
The use of hydrocarbon fuel, however, can cause complaints from environmentalists. However, if we compare this drone with a helicopter, its emission level will be, in any case, much lower.
The UAV, designed by Scottish engineers, is powered by a Rotax engine and inclined axis hydraulic motors. Details about the device told newatlas.com.
The device, dubbed the Flowcopter, promises a range of 900 km and over 6 hours of battery life, as well as a massive maximum payload of 150 kg. It was created to deliver cargo to remote settlements and coastal oil platforms, as well as to participate in search and rescue operations and agricultural use.
Engineers decided that batteries, like internal combustion engines, were not suitable for these tasks. So they decided to run the Rotax aircraft engine with a digital piston pump that can quickly and accurately control the pressure applied to the high-torque hydraulic motors that drive each propeller.
