The foldable DEA actuator
Micro Air Vehicle demo
We developed a remotely controlled fixed wing micro air vehicle (MAV) as an application to demonstrate the feasibility of the foldable actuator to a challenging problem. The aircraft shown below has a wing span of 40 cm and a mass of 137 grams and uses two foldable actuators as elevons for pitch and roll control. We have flown the MAV numerous times and found the DEA actuators allow for excellent controllability of the aircraft, as well as being very resistant to harsh handling.
Details of the actuator design and aircraft performance can be found in our publication in IEEE Transactions on Mechatronics.
