The P-51 [fighter], particularly with the advent of the K-14 gyro gunsight and the development of "Clobber Colleges" for the training of fighter pilots in fall 1944, was a decisive element in allied countermeasures against the Jagdverbände [German fighter unit]. 7, record 1, English, - gyro%20gunsight

En 1944, une innovation importante apparaît sur les P-51D : le montage du collimateur gyroscopique K-14. Par la suite, tous les nouveaux Mustangs sont dotés de cet équipement. Ce viseur, basé sur les modèles Ferranti britanniques, prévoit grâce à un calculateur analogique la position de tir souhaitable, le pilote rentrant uniquement l'envergure de l'adversaire et la distance de tir grâce à une molette sur la manette des gaz. 1, record 1, French, - collimateur%20gyroscopique

The gyros are used to maintain the platform's inertial orientation by sensing rotations of the platform caused by vehicle-rotation-induced friction at the gimbal pivot points... One gyro-called the vertical gyro-is oriented so its input axes are aligned with the X and Y platform axes; its input axes provide IMU [Inertial Measurement Unit] platform roll and pitch stabilization. The second gyro is oriented so that one input axis lies along the platform's Z axis and the other lies in the X-Y plane. This gyro-the azimuth gyro-provides platform yaw stabilization with the Z input axis, while the second input axis is used as a platform rate detector for built-in test equipment. 3, record 3, English, - azimuth%20gyroscope

The sensors for angular velocity are vibrating gyroscopes (3 axes, to detect rotation and pitch/roll pendulations of the payload). An error signal is obtained differencing the signal from the azimuth gyroscope and a constant level settable from the telemetry, which controls the speed of rotation. Such error signal drives an analog PID [Proportional Integral Differential] circuit; the output of the PID is connected to the PWM [Pulse Width Modulation] driver supplying current to the pivot azimuth motors. 3, record 3, English, - azimuth%20gyroscope

Le gyrolaser est constitué par un oscillateur optique (laser) émettant deux ondes progressives parcourant en sens inverse un chemin optique de forme en plan triangulaire, dont les sommets sont constitués par des miroirs. Lorsque l'ensemble tourne, un effet relativiste modifie les longueurs des trajets optiques, et une différence de fréquence apparaît entre les deux signaux; cette différence, enregistrée par un photodétecteur, permet de mesurer la rotation de l'ensemble avec une très bonne précision, et une insensibilité quasi totale aux conditions ambiantes (accélérations, vibrations, variations de température), d'où le développement accéléré de ce type de gyroscope au sein de l'industrie aérospatiale. 4, record 4, French, - gyrolaser

The three angular rate gyros use vibrating piezoelectric ceramic transducers to measure the Coriolis acceleration. In the 1830's G.

Notice that there is no knob to set the heading of the DG [directional gyro] to match that of the compass. Why? Because it is slaved. Slaved? Back in the tailcone of the aircraft, away from all ferrous metal, is a magnetic compass. The output of this compass is electrically "enhanced" and amplified through a "flux gate"... This signal is fed to the HSI to drive the DG portion of the unit. What this means is that the reading is very accurate, not subject to the vagrancies of the regular magnetic compass, and is constantly being corrected for drift. On some aircraft, this signal is also used to slave the ADF heading card. 2, record 7, English, - corrected%20for%20drift

Where positioning accuracy is concerned, it may seem surprising that the accuracy provided by the gyros has more impact than that of the accelerometers... This is due to the fact that navigation in fact occurs on a sphere, the Earth. It will therefore be readily understood that traveling along a straight line on the Earth comes down in fact to a rotation, and that rotation is detected by the gyros. In practice, gyros are subject to a zero-error known as gyro bias : When there is no rotation, a gyro should indicate zero, but in fact measures something that is the bias value. When an inertial navigation system is immobile, the gyros measure bias values that are integrated by the calculator and the unit thinks that it is rotating, and therefore advancing across the surface of the terrestrial globe, which generates a position error. It will be understood that position error shows linear growth over time and there is a direct relationship between the accuracy of a gyro and position drift. 1, record 11, English, - zero%2Derror

Les erreurs de mesure des gyromètres laser peuvent être représentées par des modèles mathématiques beaucoup plus simples que ceux intervenant dans l'étude des gyromètres classiques. Cela résulte essentiellement de l'insensibilité des gyromètres laser aux accélérations. La description de l'erreur d'un gyromètre laser fait intervenir : a) une erreur de zéro, due à des différences de propriétés physiques pour les ondes circulant en sens inverse dans le mélange gazeux ionisé; [...] b) une erreur imputable au blocage [...] c) une erreur de facteur d'échelle [...] 2, record 11, French, - erreur%20de%20z%C3%A9ro

The paper presents the results of development of the precision gyro device complex, designed to be used as part of control systems for carrier rockets and boosters, and also basic inertial measuring devices involved in this complex. These devices are a single-degree-of-freedom gyro unit and a gyroscopic integrator of linear accelerations with gas-static support. Essential advantages of the gas-static support usage when designing precision inertial devices as against the floated support are stated. 2, record 13, English, - gyroscopic%20integrator%20of%20linear%20accelerations

Ces mesures sont ensuite intégrées une ou deux fois pour obtenir les variations de position ou d'attitude.

The basic attitude sensor was the three-gyro inertial reference package. It contained two air-tight integrating gyro units to sense pitch and yaw, and one miniature integrating gyro unit to sense roll. The pitch and roll gyros were torqued by signals obtained by two Barnes mod IIA infrared horizon sensors. Gyrocompassing oriented the vehicle to an orbit plane yaw reference by detecting a component of the programmed pitch rate through the roll horizon sensor. The geocentric pitch rate(typically 4 deg/min, for a low-altitude orbit) was programmed as a constant torque to the pitch gyro. This pitch component, if a yaw error was present, would be sensed differentially when compared with the roll components of the two horizon-sensor heads. The differential would be seen as a function of yaw error. 2, record 14, English, - roll%20component

During heading align, the rotor of the resolver is positioned so that it transforms the N-S and E-W liquid level signals into pitch and roll components which are referenced to heading. The pitch component is amplified, demodulated and summed with amplified and demodulated feedback signals from the VG [vertical gyro] roll and pitch pickoffs and the pitch synchro. The combined signal is then modulated, amplified and converted to DC [direct current] to drive the platform pitch gimbal torque motor until the input signals are nulled. 1, record 14, English, - roll%20component
