Abstract
An air vehicle has a gas-filled hull of a flexible sheet material. Strakes extend along an exterior of the hull, each strake comprising a gas-filled tube of a sheet of a flexible sheet material. A rigid board extends outwardly from the gas-filled tube and away from the vehicle. A further sheet of a flexible sheet material extends from one side of the strake over the board to another side of the strake, to provide a strake that is generally triangular in cross section.
