Abstract: The paper describes results of a trajectory generation technique suitable for real-time implementation. The technique is used for energy extraction in wind shear. It is based on the direct method of Taranenko and is used for generating trajectories for a powered sailplane. The trajectories are generated to minimize the energy used per distance travelled in the lateral direction in the dynamic soaring cycle. The trajectories are also generated to maximise the speed. The trajectory following issues are addressed and an architecture for the control system is briefly described. Simulation is performed using a full model of a powered sailplane to verify the trajectory generation method. The results of fuel saving benefit quantification using linear wind shear models and also nonlinear windshear models are described.

Optimal morphing – augmented dynamic soaring maneuvers for unmanned air vehicle capable of span and sweep morphologies
TL;DR: The morphing UAV can perform dynamic soaring in an environment, where fixed configuration UAVs might not, because of lesser available wind shears, and the results achieved strongly support the idea of integrating dynamic soaring with morphing capabilities and its potential benefits.
