Definitions
- the present invention is in the field of solid propellant engines. It concerns more especially the destruction of reformed engines including engines that have reached the limit operational use and which are removed from service.
- a solid propellant engine includes basically a cylindrical shell hollow to inside which is placed at least one block of solid propellant, to simplify we will say by the following a block of propellant.
- One end of the envelope is closed by a dome and the opposite end by a nozzle; the dome and the nozzle will be considered as part of the envelope.
- the engines considered here are engines for which the solid propellant block has been joined with the envelope and can not be removed simply from the envelope. It's basically engine said "molded-glued" for which the block of propellant is molded and glued during the manufacture of the engine in the envelope properly prepared for this purpose. We assimilate to this type of engine those for which the propellant block, prepared otherwise, is introduced and stuck irreversibly in the envelope, this wedging being wanted or accidental. We will keep the expression engine molded glued to designate the motors treated in this invention.
- the destruction of an engine consists of first time to put it in such a state that it does not can ensure its propulsion function and then in a second step to separate the envelope and the propellant to treat them separately, given that only the propellant presents a pyrotechnic hazard that requires precautions and special conditions in his treatment for the purpose of scrapping or recycling certain elements.
- the process and the destruction facility must be able to operate at a very high cadence: it is therefore requested a process with steps simple and fast and a rustic installation.
- US Patent 5,220,107 discloses fragmentation of a block of naked propellant, that is to say not glued to inside the casing of an engine, by cooling at very low temperature of the propellant block and use of a grinder or press for fragment.
- U.S. Patent 5,025,632 discloses the extraction of propellant of a molded-glued engine with a central channel using at least one jet of cryogenic liquid. This destruction process derived from the "water knife”, is very long and does not meet the need for great pace of work. Moreover, it is potentially dangerous because we work on a whole engine.
- U.S. Patent 5,552,093 discloses the extraction of propellant of a molded-and-glued engine that has been cooled by immersion in liquid nitrogen: the block is fragmented by shocks applied in particular to the block of propellant.
- the application of shocks on propellant even cooled remains potentially dangerous and this danger is increased by the fact that, here again, an entire engine.
- fragments get stuck in the envelope and require manipulations to extract them from the envelope.
- the present invention aims to solve difficulties which are not taken into account by these various processes when one is led to design a destruction process at a very high rate and this without unreasonably multiplying the facilities running in parallel to destroy a lot engines.
- the present method therefore relates to solid propellant for which the propellant block is integral with the envelope; the engines that go into this method does not include an ignition device: it is disassembled and removed from the engine in an operation preparation before delivery of the engines to the site of destruction.
- the engine casing is either fully metal, or composite material.
- the block of propellant has a central channel that spans whole length or only part of it: in this last case the portion of the side opposite the nozzle no channel.
- the propellant block can be possibly full over its entire length, that is to say does not have a central channel.
- the sections containing propellant have a ratio length "1" of the section on outside diameter "d" of the section less than or equal to 2.5, (1 / d ⁇ 2.5).
- the process uses several jets arranged in parallel and prepositioned with respect to the motor to cut the different sections into one surgery.
- the sections containing propellant are, using appropriate means of handling, transported and immersed in a bath of a neutral cryogenic liquid vis-à-vis the section components; usually the Cryogenic liquid used is liquid nitrogen.
- the immersion of the sections lasts long enough to that the cooling of the envelope and the propellant be quite important and that the contractions differentials of the envelope and propellant create tensions cracking and cracking the propellant and also taking off from the envelope.
- the target end temperature for the engine section is at least 20 ° C below glass transition temperature range of the binder propellant.
- the sufficiently cooled sections are directed to a station to extract the propellant, weakened by the cold.
- the propellant is extracted imposing slight deformations on the envelope: these deformations remain in the elastic domain of deformation of the envelope at this temperature.
- the propellant breaks into fairly large fragments, typically the size of a closed fist.
- the stretch has been arranged vertical axis and the propellant fragments fall by gravity and are recovered either on a conveyor belt or in a receptacle containing water to render inert the propellant fragments.
- the engine section having a relatively small length compared to its diameter, 1 / d ⁇ 2.5, the propellant fragments do not get stuck in the envelope.
- the engine section cooled, vertical axis and opening of larger diameter directed downwards is arranged between a stop and a cylinder head.
- the cylinder axis is horizontal and perpendicular to the axis of the section of engine.
- the displacement of the cylinder head is calculated so that the deformation of the envelope remains in the field of elastic deformation of the envelope.
- the engine section cooled is driven between two rollers rolling mill, these rollers are suitably spaced for impose, again, a deformation that remains in the field of elastic deformation of the envelope.
- the rollers drive and slightly deform the section from the bottom of said section to its part high which facilitates the extraction of fragments of propellant by gravity.
- the empty envelope section optionally comprises some residual traces of thin propellant remained stuck in certain points of inside the envelope.
- the empty stretch is recovered for a subsequent step of disabling such residues.
- this deactivation is done in a closed chamber that includes burners whose flames burn the traces of propellant.
- the fumes are folded and washed with water: therefore no gaseous effluent is not released into the atmosphere.
- the wash waters are collected to be processed and decontaminated according to known methods.
- the deactivation any propellant residues adhering to the inside of the envelope is done by dipping the empty envelope section in said liquid.
- the oxidizing charge is dissolved in the liquid, it does not remains more on the inner wall of the envelope than matrix flaps consisting of binder and filler fuel without pyrotechnic danger.
- the kinetics of diffusion of the oxidizing charge and its dissolution in the liquid is advantageously accelerated in heating the liquid.
- the liquid containing the charge oxidant in solution is recovered for treatment subsequently by known methods. Frequently the charge oxidant is ammonium perchlorate and the liquid used to dissolve it is water.
- the propellant fragments obtained after the elastic deformation of the envelope are usually pretty big: a few inches, about the size with a closed fist.
- To move to the next stage of propellant treatment it is necessary to proceed to finer grinding of said fragments so as to obtain grains of propellant, grains whose dimensions are of the order of not more than one centimeter and preferentially a few millimeters.
- This grinding can be done in different ways but preferentially we use grinders to knives and advantageously grinding is done under water spray.
- the next stage of propellant treatment, as well put in grains, is the dissolution of the oxidizing charge in a suitable liquid, for example water when the oxidizing charge is perchlorate.
- the liquid that contains the oxidative charge in solution is separated from the solid residue; this last includes the binder and the possible fuel charge, it does not present a pyrotechnic hazard.
- the residue solid is either directly landfilled in a landfill, be upgraded to extract the metal fuel charge after known and conventional treatments for waste industrial.
- the liquid is either treated by biodegradation such as that described in the patent FR 2 788 055 or its correspondent US 6 328 891 for degrade the oxidative charge, be treated for revalorize said oxidizing charge and recrystallize it by known methods.
- Figure 1 schematically represents a installation for the implementation of the method.
- Figure 2 is a blueprint of a propellant fragmentation facility after cooling of the section.
- Figure 1 schematically represents the succession of different posts for the implementation of the process.
- the engines are brought to a storage workshop, identified for the traceability of the operation and are placed one by one on a conveyor and are introduced, one to one, through a first airlock in the facility.
- the engine is immersed in a tray containing water and positioned on a bench turning in relation to a ramp of several jets to high pressure suitably arranged: the engine is cut into sections.
- the high pressure ramps are made with standard equipment eg DIGITAL CONTROL, supplying high-pressure jets, approximately 300 MPa using two pumps. In general, there is a section that does not contain propellant but a great part of the nozzle, that section not containing pyrotechnic product is removed from the sequence.
- this post essentially includes a bath of great length in which are immersed several sections suitably spaced; the sections move as the process unfolds and so stay long in the liquid which promotes cooling to temperatures about -100 ° C.
- the suitably oriented section is deformed by compression of the envelope: the propellant, weakened, cracked and cracked by cooling fragments.
- the fragments are recovered for a further processing.
- the sections of empty propellant casing are directed to a residue deactivation station 6.
- the deactivation of sections is, in this example, made by immersing said sections in a vessel containing some water.
- the propellant fragments are directed to a fine grinding station 4 using knife mills with water spray.
- Standard devices powerful, with some security adaptations, can treat up to 1000kg / hour of propellant.
- the grains obtained after fine grinding are introduced to the dissolution station 5 in a reactor of large volume, said reactor is perfectly agitated and thermoregulated to increase the kinetics of dissolution the oxidizing charge in the water.
- Figure 2 schematically represents views a) in profile and b) in plan of an extraction apparatus 11 of the propellant of a cooled engine section 10.
- the apparatus essentially comprises a frame rectangular 13, anchored on four feet with a stop 14 on one side of the frame and a hydropneumatic cylinder 15 fixed on the opposite side; the cylinder is arranged horizontally.
- the motor section 10 to be treated is hooked, vertical axis to a handling means schematized by the reference 12. Said handling means brings the section motor 10 between the stop 14 and the cylinder rod 16.
- the cylinder rod 16 is supported on the envelope from the engine section to about one-third of its height from the bottom of the section. Moving the stem jack 16 is determined to impose a deformation to the envelope that remains in the elastic domain of deformations of it and fragment the propellant cold and separate it from the envelope.
- a receptacle 17, containing water to make inert the propellant fragments that fall by simple effect of gravity is placed under the stretch of engine; said receptacle 17 is only shown in Figure 2a).
- This unit is placed in a suitable room with entry and exit lockers and all easements necessary for remote operation.

- les tronçons ne contenant pas de propergol sont retirés de la suite de la séquence,
- les tronçons contenant du propergol sont refroidis à une température très inférieure au domaine de température de transition vitreuse du liant du propergol,
- le propergol est séparé de l'enveloppe de chaque tronçon, le tronçon est ainsi vidé du propergol qu'il contenait,
- les tronçons d'enveloppe vides sont récupérés pour une étape complémentaire de désactivation des éventuels résidus de propergol,
