초록

It is known to use a rigid cone to provide stability to a body being towed by an aircraft. However, such cones are useful over a limited range of speeds. The invention provides a drag-producing aerodynamic device in which the cross-sectional area of the structure producing drag is variable. The cross-sectional area of the structure producing drag decreases as the towing speed, and hence the dynamic air pressure acting on the structure producing drag, increases and vice versa.

청구항

[ We claim:] [1.] An aerodynamic device for producing a variable drag during towing to provide stability to a towed body, said device comprising:a) a sleeve extending along a longitudinal axis and mounted on the body for longitudinal movement along said axis;b) resilient means mounted on the body and resiliently bearing against, and resiliently resisting the longitudinal movement of, the sleeve with a restoring force; andc) a plurality of drag-producing blades having a first set of end portions pivotably mounted on the sleeve and arranged about said axis...
