Abstract: A system and method for conducting electronic warfare on a target site includes the use of a small unmanned aircraft system (SUAS) having a fuselage and a Prandtl wing, wherein at least two electric ducted fans are positioned on the fuselage. A power system of the SUAS has a plurality of hydrogen fuel cells positioned within the Prandtl wing. An electronic warfare payload is carried by the fuselage, wherein the electronic warfare payload and the at least two electric ducted fans are powered by at least a portion of the plurality of hydrogen fuel cells. During an operation, the SUAS may launch near an IAD site and initiate an electronic warfare effect on an integrated air defense site with electronic warfare payload carried by the SUAS to interfere with at least one surface-to-air missile (SAM) system.

Abstract: This invention relates to a wing comprising a generally aerofoil (or airfoil) shaped body having a leading edge, a trailing edge, a span, and first and second major surfaces extending between the leading edge and the trailing edge, where at least one of said first or second major surfaces comprises cyclic spanwise variations at or near the leading edge thereof, but not the trailing edge thereof. In preference, the cyclic spanwise variations extend substantially chordwise from at or near the leading edge, progressively diminishing as they extend chordwise so as to disappear at or before reaching the trailing edge of the wing.

Abstract: The new Deturbulator could be is a really significant drag-reducing aerodynamic invention since the development of the now-common laminar-flow airfoils that were developed some 65 years ago. Its small size and lightweight make it easy to apply on a sailplane wing. Its location on a sailplane wing may be critical, and if similar performance improvements can be achieved with the many types of high performance sailplanes.

Abstract: The invention relates to a wing for generating lift and comprises a trailing edge, a leading edge, an inner end, an outer end, a top surface and a bottom surface. The wing comprises an aerofoil with a chord line and a span direction. The leading edge comprises a kink between the inner end and the outer end. The leading edge comprises a forward sweep part between the inner end and the kink extending towards the kink presenting an angle relative to the span direction. The leading edge comprises a backward sweep part between the kink and the outer end extending from the kink presenting an angle relative to the span direction. The top surface comprises a flow control means for controlling the lift at least partly located between a leading edge part between the kink and the outer end and located between the leading edge and the trailing edge.
