Abstract

L'antenne filaire comprend une carène (2S) en aile d'avion montée à rotation libre autour d'un brin d'antenne (1S). La liberté en rotation de la carène apporte un gain considérable sur la traínée d'un engin portant l'antenne. Pour ne pas augmenter la poussée lors du décollage de l'engin, un porte-brin (3S) tourne dans l'engin pour déployer le brin seulement après le décollage depuis une position repliée sensiblement contre l'engin, vers une position (PD) formant un angle aigu avec un axe longitudinal de l'engin. L'antenne peut comprendre deux brins symétriques développés perpendiculairement au plan de sustentation de l'engin. The wire antenna includes a hull (2S) in an airplane wing mounted with free rotation around an antenna strand (1S). The freedom in rotation of the hull brings a considerable gain on the drag of a machine carrying the antenna. In order not to increase the thrust during takeoff of the craft, a strand holder (3S) turns in the craft to deploy the strand only after takeoff from a position folded substantially against the craft, towards a position (PD) forming an acute angle with a longitudinal axis of the machine. The antenna may include two symmetrical strands developed perpendicular to the plane of lift of the machine.
