A linear accelerometer using a single-degree-of-freedom gyro having a pendulosity along the spin axis that is servo-driven about the input axis at a rate that balances the torque induced by sensed acceleration along the input axis. The angle through which the servoed axis rotates is proportional to the integral of the sensed acceleration.  3, record 1, English, - pendulous%20integrating%20gyroscopic%20accelerometer

The intercontinental ballistic missiles(ICBM) and submarine-launched ballistic missiles(SLBM) developed over the past 50 years have employed successive generations of increasingly accurate inertial guidance systems. The comparatively short time of guided flight and high acceleration levels characteristic of the ballistic missile application place a premium on accelerometer performance to achieve desired weapon system accuracy. To date, the accelerometer design of choice for strategic missiles has been the Pendulous Integrating Gyroscopic Accelerometer(PIGA) instrument, an accelerometer whose origins trace back to the German V2 rocket, and has been refined through several generations of development to achieve unsurpassed performance.  4, record 1, English, - pendulous%20integrating%20gyroscopic%20accelerometer

Any spinning object posesses gyroscopic characteristics. The central mechanism of the gyroscope is a wheel similar to a bicycle wheel. It’s outer rim has a heavy mass. It rotates at high speed on very low friction bearings. When it is rotating normally, it resists changes in direction. The gyroscope exhibits two predominant characteristics. Rigidity in space. Precession.  2, record 2, English, - gyroscopic%20characteristic

The gyro has been applied as a controller in the steering systems of ships, planes, and torpedos. In these applications, the important gyroscopic characteristic being used is rigidity in space, i. e. the spinning gyroscope maintains it orientation in space.  3, record 2, English, - gyroscopic%20characteristic

De façon générale, les gyrovibrants sont des systèmes mécaniques dont certains modes de vibration présentent des propriétés de type gyroscopique. Dans le travail en cours, on s'intéresse plus particulièrement aux gyrovibrants dont le système mécanique sous-jacent est constitué par une coque mince. [...] Plus spécifiquement, les objectifs sont de 1.Mieux comprendre les phénomènes mécaniques qui sont à la base des propriétés gyroscopiques des gyrovibrants en général, et des coques résonnantes en particulier; [...]  2, record 2, French, - propri%C3%A9t%C3%A9%20gyroscopique
