Description

The present invention relates to the field of automatic control systems and can be used to provide automatic guidance and stabilization of the payload, for example, weapon systems located on a helicopter or other mobile carrier.

Known installations that use electro-hydraulic drives [1], using the energy stored in the accumulator for emergency operation when the power pressure disappears in the main source of hydraulic power. It is also known a device [2] used in a mobile helicopter gun mount helicopter, having a drawback, namely the lack of the possibility of combat use of weapons after an emergency reduction of the control object to the locked position.

The proposed technical solution is aimed at expanding the functional capabilities of the use of a movable helicopter cannon mount by ensuring its combat use after putting it in a locked position.

The essence of the proposed technical solution lies in the fact that the system for automatically guiding and stabilizing a movable helicopter gun installation contains a hydraulic power source, a check valve, a hydraulic accumulator, an actuator connected to the gun installation, a pressure loss warning device, an electro-hydraulic crane, the first "I" circuit and locking device, made with the possibility of interaction with the cannon installation and the formation of the output signal when triggered, moreover, the accumulator the heator is connected to the actuator via an electro-hydraulic valve, the pressure loss indicator is connected to the output of the hydraulic power source by the input, and the output to the first input of the first "I" circuit and the input of the actuator, the second input of the first "I" circuit is connected to the output of the locking device, output of the first circuit "I" is connected to the control input of the electro-hydraulic crane, and the accumulator is installed between the check valve and the electro-hydraulic crane, while it is equipped with a command generator forks to the stopper, by the second “I” circuit and the operation enable driver, wherein the input of the arming command shaper is connected to the second output of the actuator, the output of the arming command shaper is connected to the first input of the second “And” circuit; the second input of the second AND circuit is connected to the output of the locking device, which generates a signal when triggered, and the output of the second I circuit is connected to the input of the firing permit shaper.

The invention is illustrated in the drawing, which shows a block diagram of a system for automatically pointing and stabilizing a movable helicopter gun mount.

Information confirming the possibility of implementing the proposed technical solution to obtain the above technical result is as follows.

The system for automatic guidance and stabilization of a movable helicopter gun mount (hereinafter the system) (see drawing) consists of a series-connected hydraulic power supply 1, a check valve 2, a hydraulic accumulator 3, an electro-hydraulic crane 4, an actuator 5 and a gun installation 6. The system includes locking device 7, configured to interact with the cannon launcher 6 and generate an output signal when triggered, as well as a pressure loss indicator 8, the input of which is connected inen with the output of the hydraulic power source 1, and the output is connected to the second input of the actuator 5. In addition, the system includes an "I" circuit 9, the first input of which is connected to the output of the pressure loss indicator 8, the second input to the second output of the locking device 7 moreover, the output of the circuit "And" 9 is connected to the control input of the electro-hydraulic crane 4. The system also includes a shaper of the arming command 10, a second circuit of "I" 11 and a shaper of firing permission 12, and the input of the shaper of arming the supports 10 is connected to the second output of the actuator 5, the output setting command to the stopper driver 10 is connected to the first input of the second circuit "and" 11; the second input of the second AND circuit 11 is connected to the output of the locking device 7, which generates a signal when the locking device 7 is triggered, and the output of the second AND circuit 11 is connected to the input of the firing permit shaper 12.

The proposed installation works as follows. In normal mode, the cannon mount 6 is moved by the actuator 5 due to the energy of the hydraulic power source 1. In emergency mode, when the actuator 5 receives a signal from the actuator 5 to set the stopper 10 to bring the control object to the locked position at the output of the stopper putter 10, which means that the enable signal appears at the first input of the second AND circuit 11. At the second input of the second circuit "And" 11 at this moment there is a inhibit signal. After bringing the cannon launcher 6 to the locked position and the locking device 7 is activated, the locking signal appears at the output of the locking device 7, and therefore, at the second input of the second AND circuit 11. After this, the second circuit "And" 11 is triggered, and at its output, and therefore, at the input of the firing permit shaper 12, a signal appears allowing firing from the locked position.

Thus, after placing the cannon mount 6 on the stopper, firing from the locked position is allowed, and thereby expand the functional capabilities of the combat use of the system for automatic guidance and stabilization of a movable helicopter cannon mount.

The proposed technical solution was introduced into the design documentation of the modernized mobile helicopter gun mount, and bench tests and full-scale testing confirmed the possibility of the combat use of the system for automatic guidance and stabilization of the mobile helicopter gun mount from the locked position.
