Known multifunctional measuring system for determining the characteristics of rapidly moving objects, in particular warheads of missile and artillery weapons (Bulletin of the Russian Academy of Missile and Artillery Sciences, No. 3, 2006, p. 65, M. 2006), which was chosen as prototype for the greatest number of similar features and the problem to be solved. This complex includes an experimental test track (a platform for functional testing of rocket and artillery weapons), a test object, which is a warhead rocket, means for launching a test object, which is an accelerating device that moves along the track along with the test object, a block of recording equipment and a simulator of a target, which can be an object of various shapes, depending on the type of study, for example, an armored plate, a container with sand, etc. The target simulator can be equipped with dynamic protection, and the recording equipment block contains a synchronous-ballistic camera, a pulsed light source, electron-optical cameras, a high-speed camera and photodetectors installed along the track, recording the process of moving the test object along the track.

The disadvantage of this complex is the impossibility of obtaining sufficient information about the shape and spatial position of the object of study, which is a damaging element that is formed in the process of moving along the route, as well as at an unusually fast speed (during and after the object under study imitates the target).

The task in this technical field and the proposed solution is aimed at, is to create conditions for acceptance tests in the production process of warheads, in particular projectile-forming (SFBCH), to determine their combat characteristics in accordance with the given requirements. Necessary conditions can be provided by creating a multifunctional complex for

research and testing of warheads, including structures, measuring equipment and various devices that are maximally adapted to solve the problems of gas-dynamic tests and experimental studies: calibration of numerical methods, study of the processes of formation of PE, determination of the parameters of PE at different distances, etc.

The technical result of the proposed solution is to expand the functionality of the measuring complex by combining various studies to determine the characteristics of the test object in one experiment.

The specified technical result is achieved due to the fact that in the multifunctional measuring complex for determining the characteristics of a fast moving object containing an experimental test track, the test object, means of launching the test object, a block of recording equipment, fixing the process of moving the research object along the route, and a target simulator, means The launch of the test object includes an optical aiming system and an explosive charge, and a block of recording equipment, f The x-ray process of moving the test object along the track includes at least one radar installation, as well as portable x-ray installations placed on opposite sides of the track and at an angle to its surface, the target simulator being made up of a set of targets, the first of which, in the direction of the strike element, placed punched target, and the next one, made of several layers, delaying the fragments of the target.

The inclusion of an optical aiming system and explosive charge in the launch vehicle of the object of study allows you to create a striking element, set the target simulator at the required distance from the launch vehicle and get into it with great accuracy.

Using a radar installation allows continuous recording of speed depending on the time of the striking element on the track.

Portable x-ray installations located on opposite sides of the track and at an angle to its surface allow multi-angle, multiple shooting of the process of moving, forming and spatial position of PE.

An example of a specific implementation of the claimed device can be created at the enterprise measuring complex. This complex includes an experimental test track, which is a sandstone embankment 200 m long, 0.6-1 m high, 3 m wide, covered with concrete slabs. Along the route, several expanded platforms were made for the placement and storage of interchangeable equipment. To ensure measurements, underground in metal pipes, cable lines were drawn that had access to the armored wells with electrical connectors located near the expanded sites. The complex of devices located on the track provides with the given accuracy a quick convenient installation and fixation of the tested SFBCH, which is an explosive charge installed in the housing with a lining, from which the PE - object of study will be formed. SFBCH is equipped with an optical aiming system in the form of a cold aiming tube (TXP) installed in a mandrel on the body of the SFBCH. The track is equipped with VS-Fast high-speed color digital video installations, AKS-4M video camera and compact, weighing 3 kg., Radar installations with λ = 2.8 cm. X-ray installations in

4-10 pcs. opposite each other in pairs on both sides of the proposed trajectory of the PE. The range of operating temperatures for the operation of X-ray installations is from -25 ° C to + 60 ° C. The arrester is designed for a voltage of 200 kV, is filled with hydrogen under pressure, which provides a resource of more than 1 million inclusions and a spread in the amplitude of voltage pulses generated on the x-ray tube ± 3%. The diameter of the focal spot is 1.5 mm, and the pulse duration is 5 ns. The target simulator is a set of targets: punched, made of duralumin sheet with a thickness of 2 ... 3 mm, and delaying fragments, made in the form of a package of plywood sheets, with a total thickness of up to 100 mm. A stationary X-ray unit is located in a casemate. The pulse duration is not more than 100 ns, the size of the focal spot is not more than 4 mm, the radiation energy is from 0.2 to 2 MeV, the transmittance is 100 mm of iron.

The operation of the measuring complex is as follows. After assembling the experimental test track 1 and equipping it with all the necessary measuring equipment, install SFBCH 2, at a distance of 200 m from the simulator of target 5 on the aiming line, which is marked at a height of ~ 1.5 m from the surface of the track of the experimental test track 1. Aiming at the target is carried out using an optical aiming system 3 with a magnification factor of 5 times. To determine the immutability of aiming after removing the thermoplastic thermometer, the position of the housing of the SFBCH 3 is controlled by a laser beam. The error of hitting the target is not more than 20 cm. After undermining the SPBCH 2, the object of study begins to form and move - the damaging element. Portable x-ray installations 4 record the process of formation of PE and make it possible to obtain high-quality x-ray shadow images of the shape and spatial position of PE at different points in time. Radar installations 7 allow you to measure the speed of movement of PE with an error of not more than 20 m / s at a distance of 50 m. After the experiment, information

read from the monitor in the form of a graphical dependence of speed on time. High-speed video installations 8, 10, 11 and a movie camera 9 record the process of PE flight, its separation, interaction with a barrier simulator. The size of the holes in the duralumin sheet of the target simulator 6 in accordance with the OST determine the slaughter fragments. The technique is calibrated using PE of various weights and speeds. The use of the inventive measuring complex allows you to get a wide range of characteristics of PE at the initial stage of its formation, during the flight along the entire trajectory, as well as when penetrating the simulator of the target and after-impact.
