The proposed invention relates to the field of radio engineering, in particular to devices diagnosis and repair of radio equipment.

Known selected as the closest analogue of the method of diagnosis and repair of gas turbine propulsion, running on liquid fuel, which consists in registering the current values of the criteria for the status of the propulsion system, comparing them with predetermined reference values, the elimination of the revealed defects and carrying out of inspections, checks for signals in the electrical and low voltage circuits, the work of replacement of electrical and low voltage wiring harness, blocks and nodes, checking for the presence of signals in circuits, automatic control systems, measuring and recording control of recording equipment, check the operation of the circuits (RF Patent No. 2173451, CL IPC G 01 M 15/00, publ. 10.09.2001,, bull. No. 25).

The disadvantage of this method is the lack of control of radio equipment after it is subjected to artificial aging, which in turn significantly reduces the reliability of the determination of the technical condition and does not allow to evaluate the resource of its further operation.

The technical objective of the proposed method is an extension of the functionality and increase the reliability of determination of t the economic condition of the radio equipment of missile weapons after its operation and/or long-term storage.

The technical problem is achieved in that in the method of assessment of technical condition of radio and video communication range of missile weapons, which consists in registering the current values of the criteria of the state radio and video communication within complex missile weapons, comparing them with predetermined reference values, the elimination of the revealed defects and carrying out of inspections, checks for signals in the electrical and low voltage circuits, the work of replacement of electrical and low voltage wiring harness, blocks and nodes, checking for the presence of signals in circuits, automatic control systems, measuring and recording control of recording equipment, check the operation of the circuits, and then in it is removed from the missile weapon complex blocks of radio and video communication, conduct accelerated aging by thermal and mechanical effects. When this thermal effect on blocks of radio and video communication within 1347 hours at a temperature of 343 Kelvin, with every 270 hours to produce a registered current value criteria state building blocks radio and video communications and compare them with predetermined reference values. In addition, the mechanical stresses on the composite blocks radio and video communication through the vibration is ion effects at frequencies of 5, 10, 22 Hz, and the amplitude vibro should be 2.5 mm, and at frequencies 50, 100, 200, 400, 800, 1600, 2000 Hz the amplitude of the vibration must be 49,1 m/s2when this vibration exposure for each frequency is carried out for 40 minutes. Then assess the technical condition and decide on the prolongation of the operation of radio and video communication range of missile weapons.

Method of assessment of technical condition of radio and video communications (includes radio receivers and video signals, radio transmitters and video signals, receiving and transmitting antenna) range of missile weapons is as follows.

First inspect electrical and low voltage circuits, radio and video communications complex missile weapons on the subject of insulation, wiring, fixtures, replace defective electrical and low voltage wiring harness, check the operability of the circuits. Then check the signals in the circuits of the control and recording equipment. Then check the operability of the building blocks of radio and video channels of communication and their interaction with each other. Validation is performed in complex missile weapons, with a registration signal blocks radio and video communication, comparing them with predetermined reference values and the deviation value is deposits recorded signals from the reference to the value, exceeds the maximum blocks radio and video communications are recognized as unsuitable for further use. If the recorded signals are within acceptable limits, then blocks of radio and video communications are subjected to accelerated aging by thermal and mechanical effects for several of the pieces from the party, consisting of 20-40 pieces. Blocks of radio and video channel connection is removed from the missile weapons, and stand for thermal test set in the heat chamber, heated to a temperature K (Kelvin) for the period 1347 hours. Every 270 hours then removed from the heat chamber and re-check the operability of the building blocks of radio and video channels of communication and their interaction with each other. After conducting a thermal test blocks radio and video communications are mounted on stand mechanical impacts, where they are subjected to vibration according to the following scheme: consistently set frequency 5, 10, 22 Hz, and the amplitude vibro should be 2.5 mm for frequencies 50, 100, 200, 400, 800, 1600, 2000 Hz the amplitude of the vibration must be 49,1 m/s2(5g). The dwell time at each frequency 40 minutes At the last minute blocks radio and video communications include and verify their performance, then they switch off. After the arsenia vibration impacts assess the technical condition and decide on the prolongation of the operation of radio and video communication range of missile weapons.

Thus, by introducing the method of assessment of technical condition of radio and video communication range of missile weapons accelerated ageing by thermal and mechanical effects with subsequent health checks are expanding the functionality of the method, and also increases the reliability of the determination of the technical state radio and video communication range of missile weapons after its operation and/or long-term storage.
