Третий курс. |
Завтра первой пары не будет. Для тех, у кого нет методы и кто об английском ничего не знает: к завтрашнему нужен перевод текста, который изложен далее. Это текст из методы, которую надо было взять в библиотеке (розовая метода, Панкова, Немирова).
INTRODUCTION For many applications in guidance and control it is necessary to have available certain directional references. This references, which serve as the basis for obtaining navigational data or for stabilisation of a vehicle or some of its equipment, must be maintained despite various interferences. The device which has proved most suitable for the instrumentation of a reference direction is the gyroscope.
The word gyroscope received its name about the middle of the 19th century when. Foucgault, the French Academician, invented an instrument to demonstrate the daily rotation of the earth, and the name gyroscope was given to the apparatus.
The word is derived from two Greek words, gyros, "a circle", and skopeo, "I see", and was a very appropriate term to apply to an instrument which enabled one to see the earth's rotation1, relative to a revolving wheel more or less stable in direction with reference to the distant heavenly bodies.
A gyroscope is a heavy wheel on an axle mounted in a special frame which in ordinary applications gives to the axle the ability to move in any direction. When rotating at a high rate of spe-ed the gyroscope will take up a position from which it may only be shifted by the application of a considerable force. If the gyroscope - is big enough the efforts required to shift it rapidly may be beyond human strength. If, therefore, a big enough gyroscope be rigidly installed in an aeroplane or a ship, that aeroplane or a ship refuses to shift under the influence of air pockets or under the action of the waves.
Although Foucault's Instrument was put into use in 1852 it is known that something similar to the gyroscope was in existence as far back as in 1816-1817. Lately, however, the gyroscope has come into wide use in connection with the instrumental determination of various phases of the flight of aircraft2, That's why the aircraft instruments based upon the gyroscopic principle may roughly be defined as gyroscopic instruments. Notes to the Text:
1. … which enabled one to see the earth's rotation - который ПОЗВОЛИЛ увидеть вращение земли.
2. … in connection with the instrumental determination of various phases of the flight of aircraft – в связи с тем, что различные стадии полёта ведутся по приборам.
