Definitions
- the present invention relates to a missile provided with a releasable or separable protective cap.
- the present invention applies to a missile comprising at least one propulsion stage which is intended to propel the missile and which can be separated from the latter, and a terminal vehicle which is arranged at the front of this stage. propulsive and which makes a terminal flight towards a target.
- a terminal vehicle comprises at least one sensor, for example part of a homing device, which is sensitive to temperature.
- the present invention applies more particularly to a missile having a flight range remaining in the atmosphere and which has kinematic performance to bring the terminal vehicle at hypersonic speeds. At these high speeds, the surface temperature of the missile can reach several hundred degrees Celsius under the effect of the aerothermal flow, which can be detrimental to the strength and performance of structures, and electronic equipment and sensors present.
- the missile is generally provided at the front of a protective cap, which generally comprises several individual shells and which is intended to thermally and mechanically protect the vehicle terminal.
- This protection cap must be removed at the appropriate time, especially to allow the use of the sensor placed on the terminal vehicle in the terminal phase of the flight.
- a localized protection cap is often provided which is thus relatively light. But it is then necessary to thermally protect directly parts of the terminal vehicle that are not covered by the protective cap.
- the set is generally lighter but once the terminal vehicle disheveled, its agility is penalized by the mass of these elements of thermal protection.
- an architecture that provides that the hulls of the protective cover are articulated on the terminal vehicle, generates a large residual mass on the vehicle, due in particular to the mass of hinges or hull joints used for this purpose, and penalizes its performance during the terminal flight.
- the present invention aims to overcome this disadvantage. It relates to a missile comprising at least one separable propulsion stage and a terminal vehicle which is arranged in front of the propulsion stage, said missile being provided at the front of a separable protective cover (or releasable) comprising at least two individual hulls.
- said missile comprises a connecting piece linked to said missile, rearward beyond the position of the rear end of the terminal vehicle, and said protective cap, when mounted on the missile, surrounds all said terminal vehicle and is connected by a rear end to the connecting piece by means of articulated connecting elements.
- a protection cap that is encompassing, that is to say, which completely surrounds the terminal vehicle in normal protection position.
- Such an encompassing protective cap is certainly larger and therefore heavier than a localized protection cap, but this bounding cap structure which is linked to the missile, rearward beyond the position of the rear end of the terminal vehicle (via the connecting piece), minimizes the residual mass on the terminal vehicle after the separation, as specified below. This minimization of the mass maximizes the performance of the terminal vehicle in the terminal phase (which is the most sensitive).
- a localized protection cap is lighter than a protective covering cap as mentioned above, but requires to thermally protect all parts of the terminal vehicle that would not be covered by the protective cap.
- the set is usually more light but, once the terminal vehicle disheveled, his agility is penalized by all the mass of thermal protection become superfluous;
- said connecting piece has a general shape of a ring.

- this intermediate piece is able to be separated from said terminal vehicle.
- the protective cap, the connecting piece and the rotary connection elements form a one-piece assembly, the connecting piece being adapted to be fixed on a so-called support part of the missile.
- this support part is an intermediate part of the body of the missile, which is arranged between the terminal vehicle and the propulsion stage, and which is capable of being separated from said terminal vehicle.
- the missile comprises at least one unit for regulating the internal pressure.
- this internal pressure regulating unit comprises at least one valve arranged in at least one channel generating an air passage between the inside of the protective cap and the outside of the missile.
- said at least one channel is formed in said intermediate piece.
- the pressure difference between the inside and the outside of the protective cap may be important, the internal pressure regulating unit makes it possible to prevent the cap from deforming in flight and creates an opening allowing the introduction of the aerothermal flow liable to damage structures, equipment and a sensor of the terminal vehicle.
- said intermediate piece is configured to support the terminal vehicle and comprises ejection elements of the latter.
- the missile comprises intermediate support elements arranged between the protective cap and the end vehicle, these intermediate support elements being fixed on an inner face of the protective cap and simply being in contact with each other. an outer face of the terminal vehicle.
- the terminal vehicle also participates in maintaining the protective cap, which ensures a reasonable sizing (sufficiently low mass) of the latter.
- the missile also comprises at least one shear force recovery system between the shells of the protective cap.
- the hulls do not have to be too thick (and therefore too mass) to be able to benefit from sufficient stiffness.
- the missile also comprises means configured to create electrical continuity between adjacent shells, electrically conductive, of the protective cap, which allows in particular to provide electromagnetic protection.
- FIGS. 1 and 2 show schematically an example of a missile to which the present invention applies, provided with a protective cap which is, respectively, in a position mounted on the missile and in a release or opening position.

- the terminal vehicle 6 includes all the usual means (not further described), which are necessary to achieve this terminal flight.
- the protective cap 2 is dropped or at least open, after separation of the different shells 3 and 4, by example by pivoting, to release the terminal vehicle 6 (flying) which then separates from the rest of the missile 1.

- the protection provided by the protective cap 2 thus benefits not only the sensor 8, but also the entire terminal vehicle 6.
- the protective cap 2 encompasses the entire vehicle terminal 6 and is removed just before the use of the sensor 8 and the autonomous flight of the terminal vehicle 6.
- the autonomous flight time of the vehicle terminal 6 (with a use of the sensor 8 ) being short, it can indeed do without thermal protection during the terminal phase of the flight.
