Innovative Solutions for Multi-Rotor Flight Endurance

We propose to continue the successful development of an innovative ‘linear’ multirotor topology. Simple rotors are positioned to maximize disk area which will reduce power consumption while navigating narrow spaces. Independent control of pitch, roll, yaw and heave is accomplished like a typical quad, without the added complexity of swashplates or tilting mechanisms. Additional rotors add degrees of freedom to allow independent control of all 6 degrees of freedom. In P1 we showed that a VTOL version can transition to level outdoor flight. A 1/2kg fuel injected series hybrid power supply extends the hovering endurance from 20 minutes to several hours and allows cruise endurance which can rival any other SUAS.
