Dragonfly concept and Modelling
Large surface area
Low centre of rotation
Light and easily deployed/assembled for remote locations
‘Wings' can be fabric and ‘trimmed' for different conditions
Works with low wind speeds
Modeled using computational fluid dynamics, ‘Orcaflx'
Can be up to 3.5 m length wings or greater
Rudder can be disengaged to immobilise
Dragonfly modelling by Simon Hindley Solis Marine
Wind speed is 10m/s and playback is real time. The main body with wings when ‘flipping’ does so at about 2rad/s, the yaw rate is about 1.5rad/s. The wings move over a range of 70deg and the yaw motion is +/-40deg (range of 80deg). The rudder angle is proportional to the rotation of the wings around the main fuselage.
