Definitions
- the present invention relates to an actuation system for aerodynamic control systems, as well as systems for piloting aircraft piloted in pairs by aerodynamic control surfaces, comprising at least such an actuation system.
- the object of the present invention is to provide an actuation system simple, inexpensive and very slightly aging, which is susceptible meet the requirements mentioned above.
- the switching of the aerodynamic control surface from one of its stable active positions to the other is obtained simply by activating said electromagnetic coils, which causes a displacement of the movable pallet causing the switching of said aerodynamic control surface.
- document GB-A-1 057 863 describes a system actuation to bring an aerodynamic control surface into either of two active and stable positions, said aerodynamic control surface being rotatably mounted on a fixed support and said system comprising a single electromagnetic coil associated with said control surface, arranged on said fixed support and acting directly on said rudder (without interposition of pallet) to make it turn against the action of a spring, so that said control surface can take (exclusively, without neutral position) either of two extreme positions.
- the elements constituting said actuation system according to the present invention are few and of a limited cost. Therefore, on the one hand the manufacturing price of the system actuation according to the invention is low and, on the other hand, the volume of the actuation system is extremely small, which is very advantageous for its use on small aircraft, for example example of light missiles.
- said movable element consists of a shaft rotary.
- said actuation system according to the invention has high torque and response time.
- the present invention also relates to a system for piloting an aircraft piloted in pairs by at least two aerodynamic control surfaces, said control system comprising at least one system such as that described above.
- the invention relates, more particularly, to a control system of an aircraft in autorotation comprising two aerodynamic control surfaces arranged symmetrically with respect to the body of the latter.
- This piloting system can in particular be used on multi-mission missiles and light anti-mites, which are characterized by high speed and low mass after launch. Efficient torque steering does not requires only small aerodynamic control surfaces.
- Each of said aerodynamic control surfaces can be actuated by an individual actuation system according to the invention and said aerodynamic control surfaces are controlled, synchronously, symmetrically with respect to the body of the aircraft, by simultaneous activation of a coil of each of said individual actuation systems.
- control surfaces are actuated by a common actuation system, said system common actuation comprising a movable element additional identical to said mobile and integral element of said pallet in a symmetrical position by relative to that of said movable member, said movable member bearing one of said aerodynamic control surfaces and said additional movable member carrying the other said aerodynamic control surfaces.
- This control system is particularly suitable very small aircraft, in particular mini missiles, whose reduced volume does not allow the arrangement of several actuation systems, el including aerodynamic control surfaces of restricted surface are subject to relatively small forces and can therefore be operated by a single system actuating.
- Pilot systems with one or two systems actuators, such as those described above, and comprising two aerodynamic control surfaces with two stable positions each, symmetrically operated synchronously, are likely to take one either of two riding positions, depending on the common stable position in which are located said aerodynamic control surfaces.
- the desired steering force is easily obtained and this simply by putting the system of piloting, for respective durations more or less long, in either of these riding positions.
- F1 control value 2f / ⁇
- the previous switching mode has a downside when looking for strength very low steering.
- the actuation system allowing switching has a time threshold, corresponding to its response time. Therefore, it is impossible to obtain a corresponding 2S angle at a duration below this time threshold.
- the present invention also relates to a system piloting an aircraft with four control surfaces aerodynamics arranged around said aircraft evenly spaced.
- such a control system which is particularly suitable for a large air-to-ground missile or a planing bomb with limited maneuver is remarkable in that the opposing gouvemes are identical and in that each of them is actuated by a compliant individual actuation system to the invention.
- Figure 1 is a partial perspective view of a actuation system according to the invention.
- Figure 2 schematically shows the system piloting an aircraft, comprising two control surfaces aerodynamics powered by two systems separate actuators.
- Figure 3 schematically shows the system piloting an aircraft, comprising two control surfaces aerodynamics powered by the same system actuating.
- Figure 4 illustrates the generation of a lateral force piloting, according to a first piloting principle.
- Figure 5 illustrates the generation of a lateral force piloting, according to a second piloting principle.
- Figure 6 is the block diagram of the system piloting an aircraft with four control surfaces aerodynamic.
- the actuation system 1 is intended to operate an aerodynamic control surface G partially shown and schematically in this figure.
- said actuation system 1 has two electromagnetic coils identical A and B arranged opposite each other on a fixed support 2, which can be fixed on the body of a aircraft (not shown). Said coils A and B are can be activated independently, via a control system (not shown).
- Said actuation system 1 also comprises a movable pallet P fixed elastically by one of its ends 4 on the fixed support 2, via a leaf spring 5 secured to both of said end 4 and of said support 2.
- said blade of spring 5 is embedded by its opposite ends, at both in said fixed support 2 and in the end 4 of the P pallet.
- the other (free) end 6 of the P pallet is disposed between said coils A and B.
- a mobile element in this case a rotary shaft 7, is secured laterally to said pallet P at the end 4 of the latter, coaxially to the X-X axis.
- Said rotary shaft 7 carries the aerodynamic control surface G arranged parallel to the pallet P and shown in solid lines in its neutral position in Figure 1.
- control surface G is integral with the displacement of the free end 6 of the pallet P between coils A and B.
- the actuation system 1 can be used in a control system 12 of a aircraft 14 in autorotation around its Y-Y axis, of which is shown in Figure 2, partially and so schematically, the body 13.
- Said aircraft 14 is piloted in torque by two aerodynamic control surfaces G1 and G2 identical, arranged symmetrically with respect to to the Y-Y axis.
- Each of said aerodynamic control surfaces G1 and G2 is actuated by an actuation system 1 individual, and this synchronously, from so that said control surfaces are always in the same piloting plan.
- the coils A of each of the two actuation systems 1 are activated at the same time.
- coils B is true for coils B.
- control system 12 Depending on whether the control system 12 is located in either of these driving positions, it generates two steering forces of the same module, directed in the same direction Z-Z (perpendicular to the directions X-X and Y-Y) but in opposite directions.
- control system 20 comprises a single actuation system 1 for actuating the two aerodynamic control surfaces G1 and G2.
- the piloting of the aircraft 14 in autorotation is carried out in the same way for the two piloting systems 12 and 20 described above.
- the piloting system 12 or 20 is successively switched to its two piloting positions, thus generating at all times a piloting force of module f , of direction ZZ, and whose direction depends, at a given time, from the steering position used at that time.
- the control system 12 or 20 is kept in a first position of piloting for a period corresponding to an angle 2S of a circle C, representing the duration of a rotation turn of the aircraft and then is switched to the other position piloting for the rest of the duration of the said lap of rotation.
- Said first piloting position generates, at successive instants, on the circle C, along the circular arc defined by the angle 2S, radial forces of the same module f (as represented at points 21), while that the second piloting position generates piloting forces of the same module f but of opposite direction (as shown at points 22).
- this driving force F1 always remains greater than a minimum force.
- the control system 12 or 20 is switched in the same riding position for two durations corresponding respectively at two angles 2S1 and 2S2 on circle C and defined so these angles 2S1 and 2S2 are opposite and have the same L-L bisector.
- This second steering principle is particularly suitable for obtaining module driving forces F2 restricted, since it is possible to make the difference IsinS1-sinS2
- the actuation system 1 can also be used in a control system 25, as shown diagrammatically in FIG. 6, to fly relatively heavy aircraft, for example a large air-to-ground missile or a maneuvering bomb limited, through four control surfaces aerodynamics G3, G4, G5 and G6.
- Said aerodynamic control surfaces G3, G4, G5 and G6, each actuated by an actuation system 1 individual, are arranged around the aircraft (not shown), being each time removed from 90 °, so that, on the one hand, the aerodynamic control surfaces G3 and G5 which are identical and, on the other hand, the aerodynamic control surfaces G4 and G6 which are identical, are arranged symmetrically with respect to to the axis of said aircraft.
- the piloting of said aircraft is carried out by modifying activation of the electromagnetic coils A and B of different actuation systems 1, and therefore the position corresponding aerodynamic control surfaces.
