<p>An air launched buoy 1, eg a bathythermal buoy, is described comprising a plurality of hinged petals 6 of plastics material disposed around the body 2 of the buoy 1, the petals 6 in the pre-launch condition being retained in a forwards pointing direction and having a cylindrical skirt 9 provided between the petals and the body 2. When the buoy is launched the petals 6 are released and the petals 6 and skirt 9 assumed a rearwards and outwards configuration (Figure 2), the skirt 9 being outwards of the petals 6, retarding and stabilising the ballistic flight of the buoy 1. <IMAGE></p> |
