Subsonic Wind Tunnel Tests on the Use of Streamers to Stabilize the FOIL Bomblet

Abstract

The aerodynamics of a FOIL bomblet stabilized by streamers was studied in a small subsonic wind tunnel. For this investigation the size and shape of the streamers was based upon an earlier parametric study of the drag of isolated streamers. The reduction in drag of a streamer operating in the bomblet wake was measured and measurements were also made of the static and dynamic stability and spin damping. These measurements were compared with results obtained for a similar bomblet stabilized with a conventional fin. It is shown that whilst streamers may provide adequate static stability and spin damping, the dynamic stability at small angles of incidence is poor compared with fins though streamers may be as effective as fins in damping out very large angles of incidence.
