Coaxial-rotor aircraft: Difference between revisions

[[Multirotor]] type [[unmanned aerial vehicle]]s exist in numerous configurations including duocopter,<ref>{{Cite web|title=DuoCopter, the perfect drone|url=https://www.research-drone.com/en/DuoCopter.html|access-date=2021-11-13|website=www.research-drone.com}}</ref> tricopter, [[quadcopter]], hexacopter and octocopter. All of them can be upgraded to coaxial configuration in order to bring more stability and flight time while allowing carrying much more payload without gaining too much weight. Indeed, coaxial [[multirotor]]s are made by having each arm carrying two motors facing in opposite directions (one up and one down). Therefore, it is possible to have ana quad-axis, octorotor airframe thanks to coaxial configuration. Duocopters are characterised by two motors aligned in a vertical axis. The control is performed by the appropriate acceleration of a single rotor blade for targeted thrust generation during revolution. Having more lifting power for a greater payload explains why coaxial multirotors are preferred for nearly all large-payload commercial applications of [[Unmanned aerial vehicle|UAS]].<ref>{{cite web|url=http://www.coptercraft.com/multirotor-frame-configurations/|title=Multirotor Frame Configurations|work=Coptercraft|access-date=23 December 2015}}</ref>
