Definitions
- the present invention relates to guided missiles intended for the neutralization of air attackers more particularly those animated by a very high speed on trajectory, having a great capacity of maneuver, with approach of final attack possible either in gliding flight, or in very strong dive.
- a target is more particularly characterized by its displacement: speed, direction, maneuverability, trajectory.
- the target can be hit by a guided missile according to a law of guidance (alignment guidance, proportional guidance, etc.), which brings the missile closer to the target as the latter moves slowly and regular.
- alignment guidance proportional guidance, etc.
- An end-of-travel error must be compensated by a final maneuver of piloting the missile towards the target.
- the load factors in particular in the vicinity of the interception, must be all the more important and the response times all the shorter, the greater the maneuverability-escape performance of the target.
- a typical offensive target representing a threat that is particularly difficult to neutralize
- a supersonic missile which is extremely maneuverable and makes a final approach in sharp dive or in leveling.
- the late discovery of the hostile missile requires neutralization as soon as possible in order to ensure the security of the site to be protected.
- control surfaces causing this incidence are either of the aerodynamic type, or with control surfaces in the jet of the main propellant, or else by lateral auxiliary jets supplied from the main propellant or from independent elements.
- a response time of a few hundredths of a second can be obtained by the use of forces passing practically through the center of gravity, these forces being able to be acquired aerodynamically or by lateral jets. In this case, there is little or no aerodynamic incidence taken but direct displacement of the center of gravity.
- PAF force piloting
- the invention relates essentially to a combination of aerodynamic steering "PAF", providing in particular a high load factor with steering "PIF which on the one hand provides a great speed of response and which also makes it possible to significantly raise the total maneuverability of the missile.
- PAF aerodynamic steering
- This invention makes it possible, in combination with numerous known devices, to define various new weapon systems, capable in particular of ensuring the destruction of a supersonic aerodyne with very high maneuverability performing an approach in low-angle flight or at a very high angle. of dive.
- a first weapon system consists in vertically ejecting a missile with its accelerator off, tilting it in the direction of the target using the "PIF” piloting system, and switching on the accelerator to carry the missile at very high speed then, at the end of combustion of said accelerator, the center of gravity of the missile now remaining fixed, to be able to use “PIF-PAF” piloting.
- a second weapon system consists of dropping the missile from an aerodyne and using its specific devices to carry out a rapid rally towards the objective.
- the missile according to FIGS. 1 and 2 comprises, in the usual manner, a three-axis autopilot.
- the detection of the target is carried out on the site (for example: a surveillance radar 11A on a surface building 11 which gives the situation of the target on site, deposit and distance) and the elements treated are communicated to said missile.
- the invention proposes to associate with a missile comprising an aerodynamic piloting means with a high load factor called "PAF”, a force piloting mode called “PIF”, said piloting mode comprising means producing forces passing near the center of gravity as suggested by the examination of Figure 1.
- references 1 and 2 respectively designate the missile and its releasable accelerator.
- the missile 1 comprises: a seeker 3; piloting and guiding equipment 4; a force piloting mode “PIF itself comprising a device for deflecting jets 5 producing forces passing near the center of gravity C G and the propellant devices 6A and 6 B arranged in the vicinity of the deflection device 5 so that the known displacement of the center of gravity C G is very low during propellant of the propellant; a set of wing and aerodynamic control surfaces “PAF” bearing the general reference 7.
- the reference 8 designates the deployable stabilizer in this case the releasable accelerator 2.
- FIGS. 2 and 3 This is illustrated in FIGS. 2 and 3 where we see respectively a high performance objective 10, attacked during phase IV (FIG. 2) or even less effective but more distant objectives such as helicopter 13 or attacked plane 12 during phase V ( Figure 3).
- objectives 12 or 13 could, a fortiori, be neutralized during phase IV.
- the composite 1 + 2 missile and accelerator assembly extinguished is ejected from a site 11 at a speed of the order of a few tens of meters / second, for example using a gas generator associated with the launch tube 11 B.
- phase I the first “PIF” force piloting regime is initiated, making it possible to achieve, in phase II, the tilting of said assembly in a few tenths of a second.
- phase III the accelerator is on, causing the missile to accelerate to around 1,000 m / s.
- the seeker begins its search for target 10 and, in the event of a catch before the end of acceleration phase III, a first correction of orientation of the missile is then carried out by means of the "PIF" .
- the trajectory in the vertical plane is carried out in a slight dive in order to avoid certain possible effects such as the “image on the sea” effect for example.
- yaw and pitch control is ensured by the first operating level of the "PIF", that is to say with action of said “PIF” device, offset from the center of gravity.
- the yaw / pitch autopilot is a load factor control with high dynamic performance. It comprises a conventional aerodynamic pilot, of the “PAF” type, with a time constant of the order of a few tenths of a second, associated, in accordance with the invention, with force control, of the “PIF” type, at the center of gravity, this practically fixed time, whose response time is then very short, of the order of a hundredth of a second.
- pilot's response time is slightly lower than that of each of its components while remaining fairly close to that of the fastest.
- the third mode which corresponds to piloting in free flight, after stopping the “PIF” device, becomes of the classic aerodynamic type.
- the “PIF” device can be reactivated later.
- the actual guidance includes pre-steering and autoguiding.
- the pre-guidance is inertial, carried out from information from the center, possibly readjusted in flight every second, and data from a “strap-down” type central unit for example.
- It comprises two stages, one of tilting during which a attitude control is carried out controlled by the “PIF” device., The other of acceleration during which the missile always controlled by the “PIF” device, the other d acceleration during which the missile still controlled by the “PIF” device is directed towards an intermediate point between the current and the future goal.
- Autoguiding begins immediately after the release of the accelerator, which requires approximately 0.1 seconds.
- the guidance law is pure proportional navigation with a coefficient of around 4 with correction of the deceleration of the missile in the undisturbed flight phase.
- the increased guidance order from the output of the model 15 serves as input to the aerodynamic pilot.
- the aerodynamic pilot's servo error serves as input to both the device 16 for controlling the "PIF" and to its operating simulator 15.
- the “PIF” works as a vernier on the error of the “PAF” which makes it possible to obtain an overall device whose operating capacity is the sum of the operating capacity of the partial devices and whose response time is close to the response time of the fastest partial device.
