On the start block 24 connected to the last input of the passage of the element 13 "NO" a signal appears, which the gram block 14, the static output of the block 25 signals prohibits the operation of the block C through the permission element connected to the last input of the block 4 " n"- TI "I" of block 9, memory elements of the communication block 5 from the input elements "I", the output of the switch 17 is connected by executive elements and the counter 11. is connected to the second output of the system. Block 25 of permission signals gives signals on

Block 1 of signaling devices contains block 26 of normals - block 24 of startup, which enable the start of programmers, the input of which is connected to the input of the system (from block 14 when signals appear at the output of block 1 of sensors), and its output is from the first input of block 27 left, indicating that the parameters of the two-limit restrictions of block 1 have been reached, the second and third inputs of the threshold values and signals to block 4 "n" of block 27 are respectively connected to the outputs of block 8 and input elements "I" which prohibit its operation 28 of block 2, the output of block 27 is connected to blocks 2, bot. 3, 4, 24 and 25. The last outputs of block 26, connected to When the engine is running, the signals from the sensors block 8 and switches 15 and 17. arrive to block 26 of the normalizers of block 1

Block 2 of changing the level of reconfiguration of mis-signalers, where block 28 of "OR" elements are converted into the applied voltage, the inputs of which, due to the level of constant voltage, are convenient both for analog-block 30 of changing the maximum and block 31 of variable-digital conversion, and for using the minimum level of readjustment, the block 27 connects the boundary restrictions of block 1 and block nani with the program block 14, and the output of block 28 8 controls, functioning according to the set algo- connected with the input of block 27 of block 1 alarm rhythms. The limiters of unit 27 of unit 1 are configured, the outputs of control unit 29 are reconfigured to the limit values of the parameters (both the maximum and maximum changes when connected to units 30 and 31) and issue commands of both the minimum and minimum level of debugging and upon reaching the emergency modes of operation of the gas turbine block 9 elements "I", the inputs of block 29 are connected to the binary engine, and upon reaching the imposed (non-

emergency) operating modes for turning on auto- With the time interval "T" from the moment the engine schematics end. drive 14-4 to block 19 from block 14 to encoder 22

In the process of functioning of the system, a control frequency is made on circuit 14-5 as a sequential check of the technical condition of block 21, a signal that causes its mode of operation, in which and then block 1 at the invitation of the ACS or onboard - the input of block 21 receives a frequency signal that generates so and automatic when the parameter is reached - it removes the fixation of all measured rotation levels. frame of the gas turbine engine of the limit (set) Under the influence of the signal from the setter 22, the measuring value during its operation. tract block 21 processes the control signal and

From the speed sensor (not shown), the frequency sensor removes the fixation of all measured speed levels, a signal proportional to the engine speed, which indicates the serviceability of the measuring path, reaches block 21, which processes it according to block 21. with a successful algorithm. If the data chain is broken, if the speed measurement unit 21 is working, the number of revolutions appears at the output of the unit 18, then it does not send a signal to the unit 19 of the failure of the revolutions. a signal that prohibits the output of signals from block 21. In the event of malfunctions in the path of block 21, it reaches the specified speed levels and enters through the ele- issues a signal to block 19 of the failure of revolutions, which ment 10 "OR" to the input of the counter 11, where the register- will ensure the fixing of the failure upon receipt of signals from block 14 during operation of software block 14.

Upon reaching the specified level of revolutions, with a time interval determined by the speed of the absence of a violation of the sensor chain, block 21 of the path of measuring revolutions of block 21 sends a signal to the input to start the software block 14. A signal is issued to the control block 19 via circuit 14-6. If, to receive a start signal from block 21, there is a malfunction in the functioning of the measuring path, the block 14 on the circuit 14-1 removes the signal from the electric revolutions, then in block 19, the failure of the fix 13 is "NO", as a result of which at the output of the latter is If there is a violation in the functioning of the tract, a signal appears that allows the functioning of the measurement of revolutions, then in block 19, memory elements - triggers of block 5 of communication with the voice are fixed. The failure signal from block 19 is sent to the teaching elements, as well as to block 9 of the elements of block 20 of the "I" elements and prohibits the passage of "I" and the counter 11. Then, the program block 14 sends signals from block 21 through them, after completion, it automatically passes through the chain 14-2 signal to block 5 and fixes under control. After that, the signals are removed, which, with the help of triggers, measured the state of the outputs of block 21 on circuits 14-3 and 14-5 from the output of the rotation blocking. If the signal about reaching the target 14 is sent to the block 21 and the setter 22. At the same time, the set speed level is given by the block 21, through the block 20, the input to the measuring path of the block of elements "I" is received by the block 5 for the duration of the signal from the setter 22 control frequency, self-monitoring. This provides which goes into the initial state, and the continuity of issuing commands to the executive electrical tract of block 21 is provided by a signal from the sensor ment for the period of self-control of gas turbine engine revolutions. block 21. In addition, from block 21 the signal in the form of a straight line

Next, with the specified time interval "T" after the winding pulses, the period of which is proportional to the signal to unit 5, the program unit 14 outputs the number of revolutions of the gas turbine engine, via chain 14-3, the signal to unit 21 of measurement goes to unit 7 calculator. of revolutions, which prohibits the passage of the signal and when changing the operation mode of the gas turbine engine (not shown) of revolutions and allows the passage of the engine revolutions reach the next more elimination of the pulses of the encoder 22 of the control frequency level, a signal appears at the output of the block 21, you along the path of the block 21. The signal that is issued, which starts the program block 14. At the same time, the program block 14 on the block 21 on the chain 14 - the self-monitoring cycle of the block 21, description 3, also removes the prohibition signal coming from above, is repeated. block 18 in the event of a violation of the sensor chain and Thus, on the executive elements, signals prevent the issuing of commands from block 21 during the achievement of the imposed levels of rotations are received by self-control. The control frequency from the setter 22 only after passing the self-check is absent - it ensures the fixation of all measured levels of failure speed in the path of measuring the levels of revolutions of the blocks by the unit 21. If the unit 21 of measuring the revolutions of ka 21 and only upon reconfirmation is reached, then it is working does not issue a signal to the block 19 of canceling the set speed level. After completing your spin. If there are malfunctions in the path of checking the technical condition of unit 21, measuring unit 21, it issues to the unit 19 the failure of revolutions of sig- revolutions can begin to check the technical condition of the nal, which will ensure the fixation of the failure at the super-block 1 of the signaling devices. signal flow from block 14. After the technical condition check is completed

With the time interval determined by the speed of the revolution measuring unit 21 (in the case of the revolution measurement sequence of the unit 21, before the input of the inspection), the technical unit 19 is checked by the circuit 14-4, and a signal is issued. If the state of the unit 1 of the signaling devices. violation in the functioning of the measuring path. Checking the technical condition of unit 1 of the speed signal is absent, then in unit 19, the failure of the latches is as follows. is If there is a disturbance in the functioning of the path, the Program unit 14 on the circuit 14-7 outputs a rotation measurement signal, then in the unit 19, the drive to the input of the unit 5 is fixed and fixed in it with the help. The rejection signal from unit 19 is sent to the state triggers of the outputs of unit 1 of signaling devices, unit 20 of "I" elements and prohibits the passage of signals from unit 21, if there is a permissive signal from unit 25, through them, of signals from unit 21 after the end of self-permission at the input of the corresponding element "I" control block. ku 4.

If the corresponding block 14 signals that the counter 11 has reached the signal, it removes the specified value according to the meter, the chain block 14-10 issues a readjustment command from blocks 27 of block 1 through block 4 of the "I" elements and 30 and 31 change of the maximum and minimum enabling signal is received from block 25 to the input, respectively, of adjustment levels and channels of block 27, block 1, and element "I" of block 4, then it is fixed by block 5, re-adjusted to the set (working) levels of the exchange during the self-check. sion

Simultaneously with the output of the signal through chain 14-7. Since the signals from the sensors of the controlled pads of block 5, program block 14 through chain 14-8 of the rameters will correspond to the applied levels, the signal is sent to block 29 of the adjustment control, then at the output of block 1 signaling devices, by the alarm of block 2, which fixes the initial state of the block, signals must be issued that arrive at the inputs 27 of the boundary restrictions of block 1 to provide them to the block 24 of the launch, block 25 of permission signals and reconfiguration to issue or remove signals from the block 4 "n"- input elements "I". With the interval of block 1 outputs and to control the operation of the time block after removing the signal on circuit 14-10 from the block

From the formation of failure through block 9 elements "1". ku 14 on the chain 14-13 a signal is issued, under action

Then, from the software block 14, along the chain 14-9, the triggers of the block 25, on the control inputs of which a signal is issued to the block 4 and forbids passers-by to reach the command parameters from block 1 of the signaling devices to block 5 of the limit values, change their initial state. communication with executive elements. The following co- At the same time, the corresponding inputs of block 24 of the starting command, which comes through the chain 14-10, respectively, will receive signals that prohibit the start to blocks 30 and 31 of changing the maximum and mi- of block 14, and to the corresponding elements "I" of block 4 of the minimum debugging level, if available, signals must be received that correspond to the corresponding signals from control unit 29 to other levels of parameter limitation, allowing debugging, resets unit 27 of unit 1 to pass through them to unit 5 and further to the - issuance of signals (if the signals were not issued before this time) or their removal (if the signals were issued before After this, the prohibiting signal is removed, this time). At the same time, the signal through which the signal came through the circuit 14-9 of the block 14, and the output of block 4 "n"-input elements "I" does not pass the signal, allowing the passage of signals due to the presence at its input of a restriction on the imposed levels of parameters through the signal block with program block 14. 4 "n"-input elements "I" and further through block 5

If reconfiguration of block 27 of block 1 on executive elements. is carried out according to the self-control algorithm. From the above, we can see that block 25 of the signal, determined by the signals from the output of block 1, provides permission to issue commands that are received directly, and signals that limit the levels of parameters to the executive are received from the output of the control unit 29 resets the elements when the set levels are reached by the limitation of the unit 2 through the unit 9 of the "I" elements until the control is carried out only after the control of the functional unit. This prevents false output of signals to executive elements 14-11 from software block 14 upon receipt of the next command in the chain, not recorded. Block nti. 9 elements of "I" are intended for robot control. If when changing the operation mode of the gas turbine of block Z in order to increase its trouble-free engine, the value of the parameter became below the bone. If reconfiguration of one of the limitation level channels, then the signal at the input of block 5 of block 27 of the limit limits of block 1 is due to have. The removal of the signal of the given level - the restriction of the circuit of its sensor does not occur from the output of block 5 leads to the appearance, according to the control algorithm, then due to the action of the corresponding signal generator at the output of block 6 - a prohibiting signal from block 8 to the input of the corresponding response the trigger in block 25 of element "I" of block 9 in block C also does not fix permission signals to the initial state, in which there is a failure on this channel. the corresponding element of block 4 will be sent to the

If at least one of the channels of block 1 does not issue a null, prohibiting the passage to the executive signal, (as a result of reconfiguration, and it will not be issued by the command element of the corresponding levels of restriction), or does not remove the signal of at least the parameters, and to block 24 - a signal , allowing it, he had to remove it from the output (in the absence of the start of the software unit 14 in the event of a repeated violation of the sensor circuit), then as the previously removed signal reaches the set level of the signal from the software unit 14 in the parameter limitation block. failure is recorded. The rejection signal is sent to the executive elements of the signal input of element "I" of block 4, accordingly, it refused to reach the limiting levels of the channel pair limitation. This excludes false issuance of meters, they fall only after the passage of sa- signals to the executive elements after the passage of self-control, absence of failures in the path of block 1 of self-control. signaling devices and only upon re-confirmation

In addition, the failure signal through the element 10 of the Jenny reaching its limit "OR" parameter enters the input of the counter 11 and fixes the value. The last one removes the signal that appears in it when the signal arrives via the circuit from software block 14 to the input of element 14-12 from software block 14. When 13 “NO” is received via circuit 14-1 and software block 14 sets of the signal in the circuit 14-12 in the counter 11 is fixed in the initial state. there is also a failure of the unit 21 of the measurement of revolutions. In case of a violation of the sensor circuit of one of the cat- and a violation of the sensor circuit as an alarm, of the unit 27 of unit 1 or a failure of one of the nor- and revolutions. Simultaneously with the output of the program generator block 26 of block 1, which leads to the disappearance of the signal at its output, which is equivalent to the left from the block 25 of permission signals, it issues a signal on the emergency state of the gas turbine engine, at the start of the program block 14. After receiving the treasure, at the minimum pressure oil in the oil system of the signal from block 24, program block 14 on the engine circuit, or until the signal at the input of 14-1 removes the signal from element 13 "NO", due to the corresponding channel of block 27 of block 1, which is equivalent to what at its output from a signal appears that allows the emergency state of the engine, for example, the operation of the memory elements of block 5 is flooded by the maximum oil temperature in the oil system in connection with the executive elements, block 9, the engine element, a signal will appear at the output of block 8 , ments "I" and the counter 11. which, influencing the corresponding channel of the block 27, in Next, the program block 14 issues a signal to the block 5 through the circuit 14- circuit of the sensor or the normalizer of the block 7 and fixes according to with the help of trige- 26 a violation has occurred, it prohibits issuing the state of outputs of block 1, if there is an enabling signal to the executive element. nal at the input of the block of 4 "n"-input elements "1",

A signal about a violation of the sensor circuit, which is received from the block of 25 permission signals. failure of the normalizer of block 26 of block 1 from the output If the signal that indicates the achievement of block 8 also falls on the corresponding element with the parameter of its limit value, "|" is issued block 9 and, thus, prohibits the formation of "I" elements by block 1 through block 4, based on the presence of a failure signal on the current channel in block C with an enabling signal from block 25 at its input, then the passage of self-control, since it is broken and fixed by block 5 for the period of self-operation mode of the alarm in case of failures in lanmo control. This ensures the continuity of the sensor yoke. The failure of the appropriate normalizer for issuing commands to the executive elements for the period of block 26 of block 1 will be detected by the consequences of the self-monitoring of block 1. Decryption of flight data registered in Simultaneously with the issuance of a signal via chain 14-7 to the emergency registration system after each flight to block 5, program block 14 by circuit 14-8 of the aircraft. In addition, the signal about the signal to the control unit 29 of reconfiguration of the sensor circuit or the failure of the normalization of unit 2 and the control cycle of the operation of unit 26 of unit 1 through element 10 "OR" of unit 1 is performed according to the above algorithm to the input of the counter 11 and the current is fixed in it. when passing self-control. Calculation and issuance of signals, characteristics

If a short-term violation of the chain of dating the physical state of the parameters of the gas turbine engine occurred during the period of the absence of self-control, the engine, to the emergency registration system (for a time longer than the time constant of the normalizers for the preservation of information in the event of a disaster of the flight unit 26 of unit 1, then only the release of the device will be prohibited ), as well as the formation of boundary signals and erroneous command from the output of the corresponding limiter to block 5 is carried out in the next block of block 27 of block 1. If the command is issued in order. occurs due to the failure of one of the channels of block 27. As mentioned above, from the output of block 21 of measuring block 1, during the self-control of fixing the revolutions, the failure of the corresponding channel is sent to the input of block 7 of the computer, and the command sends a sequence of rectangular pulses, the period of which in the event that the executive element is not detected, which is proportional to the number of revolutions, it is gassed. If during several cycles of a reciprocating engine. the role of, for example, three at the output of block Z is preserved. As a result of the further functioning of the block, the signal of failure of at least one channel of block 7 of the computer pulse sequence, which follows 27 of block 1, when at least one of the block 1 is violated, is counter-pumped from the output of block 21, turns into double-circuited chains of sensors or failure, at least the code, which is fixed in the memory of block 7. of one of the channels of block 26 of block 1, as well as at Then block 7 of the computer emits signals, upon the appearance of a failure signal at the output of block 19 at the output, for example, in the form of a binary code, a stable failure signal 15 is issued to the switch of the counter 11 for alternate connection of signals from the output or violation of the sensor circuit. In the presence of block 26 of normalizers of block 1, whose signal values from the output of counter 11 and element 10 characterize the physical state of gas parameters - "OR" appears at the output of element 12 "AND" of the engine. As a result, the signal from the nal output, which through block 5 enters the on-board sys-block 26 of block 1 through the switch 15, is sent to the subject of information display. analog-to-digital converter 16, where the

In the event of a short-term, accidental violation, the binary code is broken into. With a time interval, the sensor circuit at the moment of action of the vibration pre-determined speed of the converter 16, after pulling or receiving a signal of failure of the signal to its input from the output of the torus commutator of block 27 of block 1, or block 21 of measurement 15, the computer block 7 registers in to its memory of revolutions from a random failure during the functioning of the binary code from the output of the analog-digital conversion or self-control, the next cycle of the generator 16. After the conversion of all controls, it does not give confirmation of the specified failures, which are necessary for the calculation of analog signals, as a result of which the counter 11 is reset to zero, i.e. from the output of block 26 of block 1, as well as the recording of the resul- returns to the initial state. Tats of conversion into memory block 7, the last

The automatic control mode functions - it stops issuing signals to the switch 15 and, according to the start signal from the block 24, starts to calculate the ratio of the parameters, defined in the following. When reaching one, the speed of their growth, etc. taking into account the many parameters of its limit value, block 1 will make the engine revolutions, and the calculation results give a signal to the start-up block 24, which, in connection with analyzing, for example, according to algorithms, the tolerance on its second input of the enabling signal - th control. The results of parameter calculation

and tolerance control are registered in the memory After the end of the pulse sequence on the block 7 - exceed the limit values, then block 7 forms the engine parameters, issuing signals to block 5, which, in turn, forms the co-result of the tolerance counter to block 5 and the command to executive elements. transmission of information to the emergency register system

From the emergency registration system to the entrance Z bloration is repeated. 7 of the computer receives a signal that is This and the cycle of calculation is completed, a form for the formation of a frame from the grounding information (according to the result of the tolerance control) and stored in the memory of the block 7 and proceeding to the output of signals characterizing the physical state of the switch 17 from block 26 of block 1, which characterizes the parameters of the gas turbine engine, to the executive physical state of the parameters of the gas turbine two elements and to the emergency registration system, for the gun. preservation of information in the event of an aircraft accident
