Multi-RotorPopular PlatformVarious number of rotorsStable against windHeavy-lifter
Multi purpose platformDeployable in nearly every application area
Lifting power
Proprietary & Confidential 2015-2016 5
Multi-Rotor
As number of rotors increase:+Wind resistance+Stability+Lifting power
Proprietary & Confidential 2015-2016 6
Fixed WingBest choice for:
Long flight durationLong distances
Mostly used for:Mapping
Proprietary & Confidential 2015-2016 7
HelicopterStable platform;
Generally uses petrol/nitro enginesLong flight duration
Proportional to tank size, can reach 1 hour and more Inner combustion engine allow it to service larger areas
Proprietary & Confidential 2015-2016 8
Balloon DronesOperational principals
Balloon carries drone and its payloadAdditional engines try to maintain target GPS positionEnabling drone-balloon hover over around the same area Usually solar or battery powered
Yet experimental but;Meteorologists use similar equipment for measurementGoogle is experimenting to provide internet service using drone-balloons (Project Loon)
