Onboard Trajectory Generation of Hypersonic Morphing Aircraft
International Journal of Aerospace Engineering, 2021 In this paper, a trajectory optimization strategy for the hypersonic morphing aircraft is proposed, and the AMPI method is used to generate the online trajectory with initial state errors. Firstly, the aerodynamic model and propulsion model of the hypersonic morphing aircraft were established considering the wingspan and the scramjet.

Snap-through behaviour of a bistable structure based on viscoelastically generated prestress [PDF]
, 2017 A novel form of shape-changing bistable structure has been successfully developed through the use of viscoelastically generated prestress. Bistability is achieved through pairs of deflecting viscoelastically prestressed polymeric matrix composite (VPPMC)
