Three is that the hitch point inside umbrella rib can move forward and backward, the flexible member such as spring or rubber parts strain in front portion.When low speed towed flight, in umbrella body, it is maintained at front portion along by flexible member pulling force, increases umbrella body front face area;When high speed towed flight, under wind-force effect, along overcoming flexible member pulling force to be displaced outwardly backward in umbrella body, reduce umbrella body front face area.
Four is that the rigidity being designed as umbrella body being connected with each umbrella rib is individual.Drogue is made up of umbrella rib and some umbrella sheets of some annular array, and umbrella sheet, is connected with umbrella rib fixed hinge along heading front end away from umbrella rib axle center;Rear end near umbrella rib axle center, its connection hinge with umbrella rib can on umbrella rib slide anteroposterior, and be maintained at front portion by flexible member.When low speed towed flight, umbrella sheet rear end is the most inwardly rotated by flexible member effect, and umbrella sheet front face area is big;When high speed towed flight, the wind-engaging power effect of umbrella sheet rear end is turned out backward, and umbrella sheet front face area is little.
The present invention can be used for the tapered sleeve drogue of tanker aircraft, the drogue of aerial tow target, and any utilizes air drag that object carries out the device stablized or slow down.
