Definitions
- the present invention relates to a method of automatic management of a component-type self-steering device connected to the frame, which is mounted on a flying machine, and a flying machine, in particular an air-to-air missile, which is provided with such a homing device .
- a "component linked to the frame" (“strapdown") self-redirector has, in the usual way, a fixed direction of observation, which is linked to the axes of the flying machine on which it is mounted.
- a typical homing device of a missile represents a very significant part of the total cost of this missile and can correspond to the most expensive part (sometimes up to half the cost), due in particular to the complexity of the mechanisms guidance, the details required for this orientation, and their control.
- a homodirector of "component-linked components” makes it possible, by releasing these mechanisms, to reduce their cost considerably (generally by a factor of 3 to 10), which justifies the interest of such a device. self-steering especially on a missile at low cost.
- the field of view of a component-type self-redirector linked to the frame is generally larger than that of a conventional self-redirecting optical aiming device, to allow the missile to continue to see the target despite an impact and / or missile slip, and despite the speed of the target.
- the flying machine does not arrive at the place where it is supposed to arrive and / or it is misdirected, and does not see the target;
- the target may have moved and no longer be in the predicted viewing area of the homing device at the end of the mid-race phase.
- the present invention aims to overcome these disadvantages. It relates to a method of automatic management of a component-type self-steering device connected to the frame, which is mounted on a flying machine, in particular an air missile, which has a hooking phase during which it seeks to detect a target and which comprises an observation direction, said observation direction being fixed with respect to the machine and being directed along the longitudinal axis of the latter, this management method making it possible to increase the capabilities of detection (hanging) of the target, regardless of the nature of any error (navigation error or error due to the displacement of the target), and this by avoiding the use of any sensor or additional cost.
- said method is remarkable in that it controls (or pilot) automatically said flying machine so as to describe the longitudinal axis of said flying machine, during the attachment phase of the 'homing, a circle of increasing radius as a function of time, and this until the detection of the target.
- the invention can be applied to any type of missile homodirectector component type linked to the frame (or “strapdown") and whose attachment (observation and tracking of the target) is after shooting, type LOAL ( "Lock-On After Launch”), without any other constraint (scope, job concept, 7), including a low-cost air-to-ground missile.
- type LOAL "Lock-On After Launch”
- the initial amplitude of the control depends on the field of the homing device, and is for example equal to the half-field of said homing device.
- the flying machine is subjected to two commands intended to vary, respectively, on the one hand the angle between a steering vector linked to the longitudinal axis of the flying machine and a first gear axis. , and on the other hand the angle between said director vector and a second gear axis, these two gear axes defining a plane which is perpendicular to the longitudinal axis of the flying machine, and these two commands are such that said angular variations are sinusoidal and out of phase by ⁇ / 2.
- the entire machine is imparted an oscillatory movement of its axis, to allow the homing device to scan an observation area which is considerably larger than the only field of view of the latter.
- the period of said sinusoidal angular variations increases slightly over time to allow the flying machine to widen the search area.
- the present invention also relates to a flying machine, in particular an air-to-air missile, provided with a component type self-redirector connected to the frame, which has a hooking phase during which it seeks to detect a target and which comprises a direction of observation, said observation direction being fixed relative to the flying machine and being directed along the longitudinal axis thereof.
- said flying machine is remarkable in that it comprises automatic control means for controlling (or piloting) said flying machine so as to describe its longitudinal axis, during a flight of the flying machine during the attachment phase of the homing, a circle of increasing radius as a function of time, and this until the detection of the target.
- said automatic control means are formed so as to subject the flying machine simultaneously to two commands intended to vary, respectively, firstly the angle between the director vector linked to the longitudinal axis. of the flying machine and a first gear axis, and secondly the angle between said steering vector and a second gear axis, these two gear axes defining a plane which is perpendicular to the longitudinal axis of the flying machine, and these two commands are such that said angular variations are sinusoidal and out of phase by ⁇ / 2.
- said automatic control means are part of an automatic control system of said flying machine, which comprises in a usual manner all the means necessary to fly the flying machine and guide it.
- Figure 1 shows very schematically a missile provided with a homing device, to which the present invention is applied.
- Figure 2 is a graph for explaining the characteristics of a preferred mode of control of a missile.
- the present invention is applied to a flying machine 1, in particular an air missile, shown schematically in FIG. 1, and is intended for managing the operation of a component-type self-steering device 2 connected to the frame, which is mounted on said flying craft 1.
- such a self-redirector 2 has a hooking phase during which it seeks to detect a target C, in particular a moving target.
- This autodirector 2 has an observation direction 3 which is fixed relative to the flying vehicle 1 and is directed along the longitudinal axis 4 of the latter.
- This flying machine 1 comprises usual control means 5 which are part of a usual control system 6 (connected by a link 7 to the homing device 2 and shown very schematically in FIG. 1) and which comprise all the elements necessary for guide and control the flying machine 1 so that it can reach a target C, generally mobile.
- control means 5 include information processing means which automatically generate data. piloting orders allowing the flying machine 1 to follow an intercept trajectory of the target C and control means (not shown) such as control surfaces or any other type of known elements, which automatically apply these control commands to the flying machine 1. All these usual means (of system 6) are well known and will not be further described hereinafter.
- said flying machine 1 is a "LOAL" ("Lock-On After Launch”) missile for which, by definition, the homing device 2 locks on the target C after the launch.
- This missile does not see target C at the beginning of the mission.
- the mission begins with a so-called “mid-course” guidance phase, the purpose of which is to bring the said missile at a distance sufficiently close to the target C so that the latter can then be detected by the homing device 2 .
- said flying machine 1 further comprises automatic control means 8 for controlling (or piloting) said flying machine 1 so as to describe to the longitudinal axis 4 of said flying machine 1, during a during the attachment phase of the homing device 2 (that is to say during the search for the target C), a circle of increasing radius as a function of time. This control is implemented until the detection of the target C.
- the flying machine 1 is guided and controlled according to a usual trajectory by the means 5, to which guidance and guidance is usually added the control implemented by the control means 8 to describe the flying vehicle 1 a circle around its direction of flight.
- the area which is observed by the self-steering 2 during the hooking phase is increased.
- the homing device 2 is, in fact, able to scan an observation area which is much larger than its only field of view of fixed dimensions. By therefore, the capabilities of the homing 2 to detect the target C are considerably increased, regardless of the nature of any error (navigation error or error due to the displacement of the target), and this while avoiding the use of any sensor or additional cost.
- said automatic control means 8 are part of said automatic control system 6, which comprises in a usual manner all the means necessary to fly the flying machine 1 and guide it towards a target C.
- the control means 8 are intended to vary these two angles av and aw.
- the amplitude of the angular control is preferably initially close to the value of the field of view of the homing device 2 (and may in particular be equal to the half-field of the latter, for example 1 5 °), which ensures coverage of a large angular area, without creating a blind spot in the center.
- the period is chosen according to the time necessary for observation on the zone to ensure the detection of the target C and is only given as an example in FIG. 2. It can also slowly increase over time to provide the opportunity for the flying machine 1 to expand the search area if a first pass has been unsuccessful.
- the present invention which thus widens the search area, makes it possible to reduce the impact of the drift of navigation as well as that of the displacement of the target C, and not (as the usual solutions mentioned above) only one of these two. phenomena.
