<p>The invention relates to a tethered aircraft and the control of such tethered aircrafts, for example for use in Airborne Wind Energy (AWE) applications. Tethered aircrafts can use bridles (15) distributed along the span-direction to improve the structural integrity and reduce weight, but this results in them becoming roll-limited to some extent, making normal banking and rolling inapplicable to yaw the aircraft. The invention provides solutions to yaw a roll-limited aircraft and to control the degree of roll-limitation from the bridles (15), which render the rudder and lo several other vertical control surfaces unnecessary in turning and controlling yaw of the aircraft. These can therefore be omitted with the advantages of less drag, less weight and simpler design.</p> |
