Attitude Control of Aircraft Using Only Synthetic Jet Actuators When Stall Occurs

IEEE Access, 2018
This paper proposes a novel active flow control method for a special aircraft, that using only synthetic jet actuators (SJAs) to achieve pitch-roll-yaw attitude control at a high angle of attack when the stall occurs.

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.

Simultaneously Boosting Freshwater Productivity and Antifouling Efficacy of Membrane Distillation Through In Situ Micro‐Bubble Generation

Advanced Science, EarlyView.
A superhydrophobic functional coating composed of γ‐MnO2 and perfluorodecyltrichlorosilane (FDTS) is capable of decomposing H2O2 and generating in situ micro‐bubbles on the membrane surface. The dynamic bubbles intensify the turbulence, enhancing the heat and mass transfer during membrane distillation (MD).
