A nozzle, comprising a housing; and an assembly including at least two deformable conjugated parts separated by a spacer seal, the assembly being arranged in the housing so as to form a nozzle outlet, the housing and the parts and the spacer seal being deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing; wherein the parts and the spacer seal are configured so that a force needed for inserting the assembly into the housing exceeds an assembly force that deforms of at least one of the housing and the assembly, and wherein the parts and the housing are deformed by the assembly force when assembled together to create a seal between the parts and the housing; and wherein the housing is fabricated from material having a lower hardness than the parts and the spacer seal.

Method for fluid jet formation and apparatus for the same

A nozzle having a housing and an assembly including at least two conjugated parts separated by a spacer seal. The assembly is arranged in the housing so as to form a nozzle outlet. At least one of he housing, the parts, and the spacer seal are deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing.

The method of and the apparatus for the formation of a high-speed fluid or slurry jets of a desired geometry are invented. According to the present invention a fluid or slurry jet is formed by the expelling of a compressed fluid via a slot formed by two attached plates separated by the insertion. The shape of the slot is determined by the forms of the plates and the insertion. This shape is also determined by the deformation of the plates and the insertion by the external forces applied to the plates, for example by the fasteners connecting the plates.

A method for formation of slugs in a gun barrel and acceleration of these slugs up to the speed of 3 km/sec and more is suggested. A selected region of the barrel is filled by water or another liquid, mixture of liquids or slurry. The refrigerating media is supplied into a heat exchanger cooling the selected section of the barrel. The freezing conditions (rate of the heat removal, duration of cooling) assure desired cohesion of the slug and its adhesion to the barrel. When freezing is completed, the axial pressure is exerted on the internal edge of the slug. When the pressure exceeds the adhesion forces, the slug will move toward the open end with acceleration determined by the axial forces. If the exerted pressure force is not sufficient for the slug separation the expansion radial forces are applied to the barrel or the interface between the slug and the barrel is heated. After the separation the compressed media drives the slug toward the open end of the barrel. In the course of the motion the slug accelerates up to the maximal available velocity of the driving fluid. After exiting the barrel the slug impacts a target similarly to a striker or bullet. The impact conditions are determined by the slug velocity, dimensions, shape and structure and are selected to assure a desired material modification (penetration, fracturing, spallation, and plastic deformation). In the course of impact the slug is decomposed, melted and the generated liquid is removed from the impact zone.

Selfrechargeable gun and firing procedure

A device for transverse movement of a vehicle has longitudinal rotatable axles and transverse rotatable axles, four rotatable wheels fixedly connected with two longitudinal rotatable axles, couplings through which the wheels are connected with four transverse rotatable axles, so that when wheels of a vehicle cooperate with the device, the device displaces the vehicle to the right and to the left depending on direction of rotation of the wheels of the vehicle.
