Definitions
- Universal liquid angle indicator relates to information measuring equipment and can be used to control and measure the angle of inclination of the surfaces of stationary and moving objects, vehicles, including in aviation and marine vessels as a backup horizon, which does not require power supply.
- the axis of rotation of the rotor be directed vertically.
- the gyroscope's own axis of rotation is brought into a vertical position by the pendulum correction system based on the signals of the liquid pendulum sensors [1].
- the air bubble in the liquid pendulum sensors shifts relative to the electrodes and the contact surface area of the electrolyte with the platinum electrodes changes. As a result, currents different in value and direction flow through the control windings of the correction motor.
- the engine will create a moment relative to the suspension axis of the outer frame, and the gyroscope will begin to precess relative to the suspension axis of the gyro.
- Horizontal correction is triggered in such a way that the correction motor causes the gyroscope to precess in the direction at which the mismatch angle between the main axis and the plane decreases [2].
- There is a contact in the lateral correction circuit which breaks the circuit when the aircraft makes a U-turn, reducing the turn error. Highlighted in italics - features inherent in the subject of the claimed invention.
- a disadvantage of the known device is the complex and expensive design, as well as the purpose only for a specific correction task.
- the device consists of a housing, two or three transparent tubes filled with liquid, in which a small amount of air is enclosed. Highlighted in italics - features inherent in the subject of the claimed invention.
- a disadvantage of the known device is the limited number of measured angles 0 °, 90 °, which depend on the number of transparent bubble tubes.
- a disadvantage of the known device is the limited number of measured angles 0 °, 30 °, 45 °, 60 °.
- the device comprises a fixed base with a scale, a movable base on which a transparent tube with a liquid and an air bubble (ampoule) is fixed.
- the movable base with the ampoule rotates until the air bubble reaches a horizontal position. In this case, the position of the movable base relative to the scale will reflect the measured angle. Highlighted in italics - features inherent in the subject of the claimed invention.
- a disadvantage of the known device is the establishment of a movable base in a horizontal position with each measurement. In dynamic objects with frequent changes in the angle of inclination, the use of this device is excluded.
- the objective of the invention is the elimination of time loss during the operational measurement of the tilt angles of stationary and dynamic objects in a wide range (0 ° - ⁇ 180 °, 0-360 0 ), which does not require power supply.
- the technical result is achieved by the fact that to measure the tilt angles, a liquid, an air bubble or an index ball located in the cavity of a semicircular or circular transparent tube, without being brought into a horizontal position under the influence of gravity, directly displays the measured angles relative to the scale applied to the transparent tube.
- the universal liquid angle indicator contains a semicircular or circular transparent tube 1, in the cavity of which there is a liquid 2, an air bubble 3 or an index ball 4.
- the presented diagrams (Figs. 1-8) with the base are directly placed on the measured object.
- the indicated circuits consist of bases on which semicircular transparent tubes with an open circuit are fixed, and are intended for measuring angles in the range 0 ° - ⁇ 180 °.
- the device (Fig. 3) measures angles in the range 0 ° - ⁇ 180 °
- the device (Fig. 4) measures angles in the range 0 ° - 360 °
- the indicators are physical pendulums - balls moving relative to the scale deposited on transparent semicircular tubes.
- Devices (Figs. 5-6) measure angles in the range 0 ° - ⁇ 180 °
- devices (Figs. 7-8) measure angles in the range 0 ° - 360 ° relative to the X or Y axes (Fig. 7), X axes, and At (Fig. 8).
- Transparent tubes made in the form of a semicircle or a circle with a closed circuit, reduce the parasitic inertial forces exerted on the liquid when measuring angles in dynamic objects.
- mutual compensation of inertial forces inertial forces directed clockwise and counterclockwise are mutually compensated
- Figs. 5-8 as backup non-electric devices (with phosphor scales) for measuring roll and pitch angles in aviation and maritime navigation
