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 ...
The lower gyro is torqued to precess in azimuth to drive the azimuth gimbal motors. The upper gyro is caged to the lower gyro in azimuth. The gimbal servo motors position the gimbals to compensate for the original deviation. to provide the voltages for the starting and running of the gyro spin motors.
A gyro gunsight (G.G.S.) is a modification of the non-magnifying reflector sight in which target lead (the amount of aim-off in front of a moving target) and bullet drop are calculated automatically. The first examples were developed in Britain just before the Second World War for use during aerial combat , and more advanced models were common ...
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 ...
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 illuminated projection of an aiming point or some other image superimposed on the field of view.
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.
English: Block diagram of a simple reflex radio receiver, an unusual type of radio receiver invented by Marius Latour and William Preiss in 1917 that was used to a limited extent in the 1920s. The distinguishing feature of the reflex circuit is that the amplifier is used to amplify both the radio frequency (RF) and audio frequency (AF) signals ...
The CompM2 is a battery-powered, non-magnifying red dot type of reflex sight for firearms manufactured by Aimpoint AB. It was first introduced in the U.S. Armed Forces in 2000, [1] designated as the M68 Close Combat Optic (M68 CCO; NSN: 1240-01-411-1265). It is also known as the M68 Aimpoint and is designed to meet United States military standards.
