Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Role of Magnetic Materials in a Novel Electrical Motogenerator for the More Electric Aircraft
IEEE Transactions on Magnetics, 2014 The more electric engine concept considers the electric motor-generators included inside aircraft reactors. Because of the environment characteristics, the problem of reducing the losses in these machines becomes crucial. For such a purpose, this paper focuses on the magnetic losses, analyzing a small (10 kW) 12-phase induction motor-generator ...
