Definitions
- the present invention relates to devices which can be released from an aircraft, of the type provided with passive aerodynamic stabilization means, such as fins, intended to take an initial trajectory after dropping substantially parallel to the speed of the aircraft.
- passive aerodynamic stabilization means such as fins
- aircraft should be interpreted as covering both rotary and fixed-wing aircraft.
- the invention finds an important application in the field of infrared or electromagnetic decoys which, to be effective, begin to play their role near the aircraft to cause the attachment of a self-steering or a radar. a hostile, then must move away in a sufficiently progressive way so that the auto-director or the radar remains hung on them, but sufficiently fast so that a missile auto-director or a radar cannot, after extinction of the lure , hang on the aircraft again.
- a non-propelled, aerodynamically stabilized lure is given a drag coefficient Cx such that it gives the machine a satisfactory separation from the plane at high speed and low altitude, this coefficient cannot provide sufficient separation for ejection at lower speed or higher altitude, due to the drop in dynamic pressure.
- the machine further comprises flaps which can be deployed automatically after release.
- each of these flaps 17, four in number is constituted by a spring steel plate, the front part of which is held pressed against the body by fixing means, such as screws 18.
- the flaps 17 are kept applied against the body of the machine, under the fins 14, and are therefore compact. They are preformed in the deployed position, so that they are then under tension and that in the absence of stress they take a free position making a determined angle a with the axis of the machine ( a ⁇ 45 ° for example).
- the elasticity of the flaps is such that the dynamic pressure exerted on them in flight gives them an angle relative to the axis of the body which depends directly on the dynamic pressure and which is less than a .
- the length of the flaps 17 and the fins 14 is such that they do not project beyond the rear of the body.
- each flap 16 is reinforced by shorter elastic strips 20 whose presence modifies the law of deformation. These additional blades will be present or not according to the law of variation of the drag to be given to the machine. They are fixed flat on the flaps, for example by rivets 22.
- the shape of the fins 14 and that of the flaps 17, as well as the nature of the means for fixing the flaps, depend on the envisaged application. It may be indicated by way of example that, in the case of a device constituted by a decoy having a caliber of 30 mm and about twenty centimeters in length, four flaps devoid of reinforcing blades, of 0.6 mm thick spring, fixed to the body by a few solder points.
- each flap 17a is constituted by an elastic metal blade (spring steel in general), articulated on the body to the back of the skates.
- each flap 17a can be welded to one of the elements of a hinge 24 placed immediately behind the rear sockets 16.
- the hinges have a limited clearance, so that the flap in the free state, once turned towards the rear , make an angle b of about 45 ° with the axis of the body, near the hinge.
- the flap 17a is designed to be folded towards the nose of the vehicle when it is stored and to be kept in abutment against the body by a fin 14 (FIG. 4).
- the flap can be preformed so as to take the form shown in solid lines in FIG. 5 as soon as the machine is ejected and the fins 14 deployed.
- the flaps 17a have a raised beak 26, their deployment is caused by the action of the wind on the spout.
- the wind action can be replaced or supplemented by that of other means, for example by a pincer spring mounted on the hinge 24, a spring intended to slightly detach the flap from the body when it is released, or a wire of traction connected to the corresponding fin.
