Description

DEVICE for indicating spatial position.

The utility model relates to the field of vertical display using instruments based on the use of the gyroscopic effect, and can be used to indicate the spatial position of various objects, in particular roll and pitch of aircraft.

A device for indicating the spatial position of the aircraft 1, containing a built-in source of information about the spatial position, the control unit health and servo systems and the display unit.

The known device has significant dimensions and weight. In addition, some of its characteristics, such as nutrition, do not correspond to modern aircraft.

It is also known a device for indicating the spatial position of the aircraft 2, also containing a built-in source of information about the spatial position, connected to it, a health monitoring unit and tracking systems and an indication unit.

Despite the fact that this device has more acceptable weight and size and other characteristics for modern aircraft, it has insufficient accuracy and low reliability. The low accuracy of the known device is due to the fact that the built-in sources of information about the spatial position (usually gyro sensors) of such devices, due to a number of restrictions imposed on them, cannot have a sufficiently high accuracy class, and low reliability is caused by the fact that the device’s overall performance depends on mainly, from the performance of the gyro sensor, which is quite complicated and, therefore, prone to failure by the device.

IPC GDI with 19L4

The objectives of the claimed utility model are to increase the accuracy of the indication of the spatial position and reliability of the device.

The proposed device for indicating the spatial position includes a display unit, a connected health monitoring unit and servo systems, and an integrated source of information about the spatial position.

According to the claimed solution, a switching unit is inserted into the device, included between the built-in source of information about the spatial position and the health monitoring unit and the following systems, and the line of information about the spatial position and health, the inputs of which are connected to the external source of information about the spatial position, the outputs of the lines of information about the spatial position are connected to the health monitoring unit and servo systems, and the output of the health information line is connected to the switching unit.

The goals are achieved by the fact that due to the introduction of a switching unit and information lines, the device is actually supplemented by another external source of information about the spatial position, which, in particular, can be used the inertial cursor vertical of the aircraft, which has increased accuracy compared to the built-in gyro sensor and, thus, when connected via newly introduced information lines and a switching unit, significantly increasing the display accuracy of the spatial position Niya. In addition, the built-in and external sources of information reserve each other and, in case of failure of one of them, there remains the possibility of receiving information from the other, which increases the reliability of the device.

The figure shows a block diagram of a proposed device for indicating spatial position.

The device for indicating the spatial position contains a built-in source 1 of information about the spatial position, a switching unit 2, a unit 3 for monitoring health and tracking systems, and an indication unit 4.

In addition, there is no part of the device for indicating, an external source 5 of information about the spatial position, from which there is a line 6 information about health, connected to the unit 2 of the switching and lines 7 and 8 information about the spatial position, connected to the block 3 health monitoring and tracking systems. The outputs of the built-in source of spatial position information 1 are connected through the switching unit 2 and the health monitoring unit 3 and servo systems with the indication unit 4.

The device for indicating the spatial position, if you exclude the switching unit 2 and the lines connecting it to the external source 5 of information about the spatial position, as a rule, is a normal horizon for indicating roll and pitch (for example, AGR-29 model).

As an external source 5 of information about the spatial position, any inertial gyro vertical available in a modern aircraft can be used. The switching unit 2 can be implemented, in particular, on several relays according to a known scheme.

A device for indicating spatial position operates as follows.

The pilot has a toggle switch to switch between using the external 5 and built-in 1 sources of information about the spatial position.

When operating in the mode of using an external source of information, the aircraft positioning in roll and pitch is indicated from an external information source 5, i.e. from an aircraft inertial course-line, from which information about the health of an external source 5 is received via the health information line 6 to the switching unit 2, and information about the aircraft roll and pitch is transmitted to lines 7 and 8 through the health monitoring unit 3 and tracking systems to the indication unit 4 . In case of failure of the external source 5, information about this on line 6 goes to the switching unit 2. And it automatically switches the display unit 4 to work from the information of the built-in source 1, i.e. gyro sensor of the horizon.

When operating in the mode of using the built-in source of information, the aircraft position and roll pitch indication is performed from the built-in information source 1, i.e., from the gyro-sensor of the horizontal horizon, without automatically switching to work from external information source 5, but with the possibility of manual switching by the pilot to work from information from an external source 5.

Using the proposed device gives the pilot the opportunity to create a combined horizon, working in two modes: either an autonomous horizon using its own vertical sensor or in the roll and pitch indicator mode from an embedded vertical sensor with increased accuracy and reliability.
