Definitions
- the present invention relates to a device for correcting trajectory for gyroscopic guided projectiles.
- the known trajectory correction systems of projectiles act during the terminal phase of the trajectory.
- the first type includes a skirt formed of Deployable "petals” to control the trajectory of the projectile by increasing its drag. At an appropriate time, the rotation of a camshaft which deploys the petals.
- the major disadvantage of this type of system is that the correction only intervenes on the errors of scope. Lateral deviations due to wind or pointing errors are not not corrected.
- Duck system corrects longitudinal deviations and lateral by creating a force in a fixed plane using fins ducks arranged on the proximity rocket and turned, which are decoupled in roll of the projectile.
- the relative movement of the duck by compared to the rocket makes it possible to form an electric alternator.
- This rocket is interchangeable with respect to the projectile.
- One of the disadvantages of this type known is that the projectile (a shell in this case) thus equipped with duck becomes incompatible with the firing gun loading system existing.
- the major drawback of piloting by duck is that it does not allow not to obtain significant load factors since it displaces the projectile.
- the duck clearly decreases the aerodynamic finesse of a projectile, which is very detrimental to the range of a tight shot.
- a first system consists of two strips of material piezoelectric articulated on a rocket close to shells, and acting each on the tension of a small canvas forming a fin.
- the rocket is interchangeable with respect to the shell and is decoupled in rotation in roll.
- This system is compatible with the shell loading device in the barrel, and applies in particular to statically unstable shells.
- a second known system includes rigid micro-control surfaces arranged on the proximity rocket of a shell, and has the same advantages than the first system.
- these two known systems not suitable for piloting mortar projectiles stabilized by rotation, because these move in subsonic and transonic flight following a curved trajectory.
- the effectiveness of these micro-control systems is too low to obtain a sufficient load factor for them trajectory corrections, because the low load factor leads to the need to detect the target at a distance greater than the detection capabilities of the laser system fitted to the proximity rocket.
- the trajectory correction must be greater.
- the detection system laser fitted to these projectiles has a range not exceeding 2 km per time heavy rain, which makes it necessary to give these projectiles lift and fineness superior to that of mortar projectiles. It follows that the existing systems do not allow correct trajectory correction such projectiles.
- the subject of the present invention is a device for correcting trajectory for guided and rotating projectiles about their axis longitudinal, whether these projectiles are fired or curved, a device which significantly improves the correction of precision deviations and accuracy, which is easily adaptable to existing projectiles, and this, without considerably increasing the cost price of these projectiles.
- the trajectory correction device for guided projectiles stabilized in flight by gyroscopic effect by rotation at high speed (for example at least 200 rpm) around its longitudinal axis, has a tail arranged at the rear of the projectile and a duck piloting device arranged on the rocket near this projectile.
- the trajectory correction device of the invention is implemented work for "gyroscopic" projectiles that is to say stabilized by rotation around their longitudinal axis. These projectiles can be projectiles mortar or artillery shells.
- the trajectory errors that we want to correct are errors of precision and errors of accuracy.
- the precision refers to random dispersions of impact points inherent in the weapon systems employed, which cannot be compensated by a change in the score of these weapons. This error of precision intervenes mainly on range deviations.
- the accuracy of the shot corresponds to the repeatability of the precision error during a certain period of time, unchanging pointing. Near misses are due to atmospheric disturbances (variations in wind direction ...) and at pointing errors. These errors can be corrected by a change aiming gun. Near misses translate into longitudinal and lateral deviations of the impact points of the projectiles.
- the above-mentioned type error correction device essentially comprises a navigation control device placed in the proximity rocket of the projectile, a control device of aerodynamic piloting arranged on this rocket and a tailplane disposed on the base of the projectile.
- Figures 1 to 3 show three embodiments of the control surfaces and empennage of the conforming trajectory correction device in the invention, for a mortar projectile ( Figures 1 and 2) and for a shell artillery ( Figure 3).
- the projectile 1 of FIG. 1 essentially comprises a body 2, a warhead proximity rocket 3 and a base 4 from which protrudes the tail load carrier 5.
- the rocket 3 has only one degree of freedom with respect to the body of the projectile, rotating in roll.
- An obliquely fluted ring 6 is attached to the front of the base 4. It is used to give the projectile a movement of rolling rotation thanks to corresponding scratches in the mortar barrel.
- Articulated fins 7, for example four in number, are arranged at the rear of the base 4, and are described in detail below with reference to Figures 4 and 5.
- FIG. 2 shows another mortar projectile 8, similar to that of figure 1, but equipped with another correction device according to the invention.
- the projectile 8 has the same body 2 and the same ring 6 that the projectile 1, and its base 4 'is similar to the base 4, the only difference resides in the fact that the base 4 'carries at its rear part not articulated fins, but a set 8A of fixed micro-fins, for example 32 micro-fins.
- the “skirt” 9A of the proximity rocket 9 of the projectile 8 covers the front part of the body of the projectile to which it is connected by a ball joint device, as shown in figure 9.
- the artillery shell 10 of FIG. 3 has at the front of its warhead 11 a proximity rocket 12 similar or identical to rocket 3, with the same duck system.
- a proximity rocket 12 similar or identical to rocket 3, with the same duck system.
- the projectile is equipped with four fins 7 identical, arranged at 90 ° around the axis of symmetry 16 of the projectile.
- these fins 7 have an elongation (ratio between their wingspan E and their width L) of 4, their wingspan being 100 mm and their width of 25 mm.
- These fins 7 have an aerodynamic profile symmetrical suitable for transonic flight, profile known per se, in order to minimize their wave train.
- the cover 17 After ejection of the projectile from its launch tube, the cover 17 is ejected, and its fins deploy by centrifugal effect and are blocked at an angle ensuring an arrow F about 15 ° (this arrow F is the angle formed between the leading edge of the fin and the plane P perpendicular to the axis of symmetry 16, and tangent to the edge leading edge at its lower part, the leading edge being behind this plane).
- This arrow F decreases the critical Mach number at the incidence of operation of the projectile.
- Each fin 7 is mounted by means of a device 18 of ball type on a support 19 fixed on a disc 20 common to all fins and which is parallel to the plane P.
- a blocking device 21 of the ball and spring type is mounted cooperating with a suitable notch 21A, formed on the leading edge of the fin, almost at the level of the articulation device 18, to allow blocking the fin at said inclination ensuring the arrow F.
- the disc 20 is mounted free in rotation around the axis 16 on a self-lubricated ring 22, for example of the “Metapharm” type, resistant to gradients of important temperatures.
- the ring 22 is fixed on a sleeve 23, itself attached to the rear face of the base 4.
- FIG. 6 shows, in a simplified manner, part of the set 8A of micro-fins fixed on the base of the projectile 8 of FIG. 2.
- This assembly 8A comprises a ring 24 which is fitted to the part rear of the base 4 '.
- the outer peripheral surface of the ring 24 is conical in shape, opening towards the front of the projectile.
- the opening angle A of this conical surface is approximately 5.7 °.
- We fix on this conical surface a large number, for example 32, of radial micro-fins, regularly distributed, of which only one, referenced 25, has been represented in FIG. 6.
- the ring 24 and the micro-fins are fixed relative to the projectile.
- the micro-fins have a shape suitable for subsonic and transonic flight.
- each micro-fin 25 has, in plan, a shape trapezoidal, with a length L 'of 11 mm and a height H of 9 mm, this which corresponds to an elongation of L '/ H of about 1.2.
- the arrow F ' (defined in the same way as the arrow F of the Figure 5) is approximately 15 °.
- the total span E (measured from the axis of the projectile) of the micro-fins is approximately 120 mm.
- the device 14 of micro-fins mounted on the rear part of the shell of shell 10 and fixed by compared to the latter.
- This device 14 includes a large number, for example 32, of micro-fins, of which only one, referenced 26, was represented.
- These micro-fins are fixed evenly on a ring 27 whose outer peripheral surface is conical, with an opening angle A 'of approximately 7.5 °, for example. They have, like the micro-fins 25, a substantially trapezoidal shape, but their large dimension, instead of being directed radially as it is the case in figure 6, is directed longitudinally.
- the arrow F "on the leading edge of each micro-fin is about 45 °
- its height H "(height on the side opposite the leading edge) is about 14 mm
- the wingspan E "(measured between the axis of symmetry of the shell and the side 26A) is 155 mm.
- the proximity rocket 28 can equip the projectiles of Figures 1 and 3, has been shown in a very simplified manner in Figure 8. It is mounted on a bearing 29 centered with respect to the axis of symmetry 30 of the projectile, this bearing being fixed by a screw 31 on the front face of the warhead 32 of the projectile (this warhead is either the warhead 2A of the projectile of FIG. 1, or the warhead 11 of the shell of FIG. 3).
- the rocket 28 has a degree of freedom, in rotation around axis 30.
- the rocket 28 contains, inter alia, a computer 33 connected to a laser detector 34 and to motors, only one of which, referenced 35, was represented.
- the number of these motors is equal to the number of duck fins namely four in this case. All of these motors are, for example piezoelectric type.
- the motor 35 controls, via a train of gears 36, a "duck" fin 37 and a complementary fin, called “Tab” 38, arranged behind the duck fin. These fins are movable in rotation in laces and in pitch, the fin 38 being optional.
- the proximity rocket 9, shown in a very simplified manner in Figure 9, is that fitted to the projectile of Figure 2. It is connected to the face frontal of the projectile warhead 2A by a ball joint 39, the ball joint being centered on the axis of symmetry (and rotation) 40 of the projectile. Because the skirt 9A covers the end of the warhead, the angular movement of the rocket in planes passing through the axis of symmetry 40 is limited. In an example embodiment, this travel is ⁇ 20 ° from the central position of the rocket (the one for which its own axis of symmetry is confused with axis 40). On the other hand, the rocket can rotate freely in roll around axis 40.
- the rocket 9 comprises, inter alia, a computer 41 connected, of a part, to a laser detector 42, and secondly to motors 43, the number is equal to the number of duck fins fitted to the rocket, namely four in this case.
- Each of the motors 43 controls, by via a gear train 44, a duck fin 45, these fins being regularly distributed around the periphery of the rocket.
- the center of gravity of the rocket can advantageously coincide with the center of the sphere of the ball joint 39.
- the rocket conical in shape, has an apex angle of about 24 °, which provides said travel of ⁇ 20 °.
- the focus of each fin duck is advantageously in coincidence with the center of gravity of the rocket.
- the fins 37 have, in a example of an E1 10 mm wingspan, a C1 cord of 4.5 mm and an arrow 30 ° F1, which allows the fins to operate at a total incidence (i.e. own incidence of the projectile, plus angle of steering of the rocket relative to the axis of the projectile) of approximately 30 °.
- the piezoelectric motors can be very small (for example example about 1 cm in diameter).
- Their gear trains 36 increase the steering precision of the rocket and the torque supplied by motors.
- Tabs 38 are turned in the opposite direction that of the corresponding fins 37, in order to reduce the moment of hinge due to the fins.
- Tabs 38 have a span (measured as E1) of approximately 5 to 8 mm and a cord (measured as C1) of approximately 1 to 1.5 mm. Their distance to the corresponding fin (distance between their edge leading edge and trailing edge of the fin) is approximately 0.5 to 1 mm.
- alternator the fixed and movable parts of which are integral with the parts fixed and mobile bearing, respectively.
- This alternator then constitutes a energy source for the electrical and electronic circuits of the rocket.
- the operating principle of the projectile 1 of FIG. 1 is breaks down into three phases.
- the first corresponds to the launch and start of the trajectory.
- the fins 7 are folded and held in position by the protective cover 17.
- the projectile accelerates into the tube and rotates with the scratches on the tube.
- the projectile and the load carrier 5 are not separated. Flight stability is provided by the gyroscopic effect.
- the load carrier separates from the projectile carrying with it the cover of closing.
- the fins are driven by friction in rotation. They unfold by centrifugal effect and lock in their position thanks to the system 21 ball with spring (for example).
- the projectile During the second phase of flight, the projectile has a gliding type trajectory with finesse corresponding to the configuration with unfolded fins. The tail fin 7 is braked to a stop by aerodynamic forces.
- the laser detector 34 identifies the exact position of the goal. Projectile piloting begins and ends continues until the target hits. It is possibly possible to treat moving targets indicating future goal at launch. The detector obviously requires a known laser target designation system of those skilled in the art.
- Errors in precision and accuracy and variations in initial conditions and atmospheric conditions for a 120 projectile mm "spinned" (rotating on itself) are included in a standard deviation equal to 50 m radius. It is considered that 99% of the shots are in a circle with a radius of two standard deviations, i.e. 100 m for a span of the order of 8 km and a flight time of 40 seconds.
- the load factor admissible by the projectile allows to correct the trajectory of 100 m on a distance of 530 meters.
- the detection capacity is around 5 km per clear weather and only 2 km in heavy rain. Therefore, we have plenty of time to make this course correction.
- the operating principle of the projectile of figure 2 is breaks down into two phases: a ballistic phase corresponding to the start of the trajectory, which remains identical to that of the standard projectile, because the zero incidence drag is identical, and a terminal phase controlled.
- the performances of this type of projectile allow to correct the dispersion of a mortar projectile over a flight distance of 1200 m. These performances are lower than those of the projectile of figure 1, but sufficient.
- the advantage of this projectile is that it does not require no changes to the load carrier tail, and therefore is a lot less expensive.
- the operating principle of the projectile of figure 3 is breaks down into two phases: a ballistic phase corresponding to the start of the trajectory, which remains identical to that of the standard projectile and a piloted phase.
- the performances of this type of projectile allow correct the dispersion of an artillery shell over a distance of 2000 m.
- the fineness of the projectile being greater than with a projectile, standard, its range can be increased by a gliding flight.
- the advantage of this type is that it does not require modification of the shell artillery, while ensuring a good capacity of correction.
