AbstractA load carrying aerial device having an inflatable component which is inflatable from a collapsed configuration to an inflated aerofoil configuration and which is maintained inflated in flight by air introduced into the component through an air intake as a result of relative motion of the component and the surrounding air. The leading edge of the component throughout its length or substantially throughout its length is closed or maintained closed in flight and is inclined at such an angle to the longitudinal axis of the component that the internal stagnation pressure of the air within the component at the leading edge produced by the relative motion of the component and the air always exceeds the external static pressure of the air on the leading edge, thereby ensuring maintenance of the profile of the leading edge in flight.
