The problem of computing the gyro angle setting is a trigonometry problem that is simplified by first considering the calculation of the deflection angle, which ignores torpedo ballistics and parallax. [44] For small gyro angles, θ Gyro ≈ θ Bearing − θ Deflection. A direct application of the law of sines to Figure 3 produces Equation 1.
The FMS can be summarised as being a dual system consisting of the Flight Management Computer (FMC), CDU and a cross talk bus. The modern FMS was introduced on the Boeing 767, though earlier navigation computers did exist. [1] Now, systems similar to FMS exist on aircraft as small as the Cessna 182. In its evolution an FMS has had many ...
The heading indicator is arranged such that the gyro axis is used to drive the display, which consists of a circular compass card calibrated in degrees. The gyroscope is spun either electrically, or using filtered air flow from a suction pump (sometimes a pressure pump in high altitude aircraft) driven from the aircraft's engine .
Diagram of a gyro wheel. Reaction arrows about the output axis (blue) correspond to forces applied about the input axis (green), and vice versa. A gyroscope is an instrument, consisting of a wheel mounted into two or three gimbals providing pivoted supports, for allowing the wheel to rotate about a single axis. A set of three gimbals, one ...
A ring laser gyro (RLG) splits a beam of laser light into two beams in opposite directions through narrow tunnels in a closed circular optical path around the perimeter of a triangular block of temperature-stable Cervit glass with reflecting mirrors placed in each corner. When the gyro is rotating at some angular rate, the distance traveled by ...
A rate gyro is a type of gyroscope, which rather than indicating direction, indicates the rate of change of angle with time.If a gyro has only one gimbal ring, with consequently only one plane of freedom, it can be adapted for use as a rate gyro to measure a rate of angular movement.
The diagram (right) shows one of the most common single tube reflex circuits from the early 1920s. It functioned as a TRF receiver with one stage of RF and one stage of audio amplification. The radio frequency (RF) signal from the antenna passes through the bandpass filter C 1 , L 1 , L 2 , C 2 and is applied to the grid of the directly heated ...
A reflector sight or reflex sight is an optical sight that allows the user to look through a partially reflecting glass element and see an aiming point or some image (helping to aim the device, to which the sight is attached, on the target) superimposed on the field of view.
