English

Subject field(s)
  • Spacecraft
DEF

A device which makes use of a planet’s magnetic field to stabilise a satellite.

CONT

The angular momentum of a tumbling orbiting satellite is changed to reduce the spinning of the spacecraft such that the spacecraft can operate in an essentially stabilized condition. The change in spin rate is accomplished by the development of a magnetic torque by commutation of magnetic air coils in response to Earth sensor signals controlled by spacecraft logic. The coils are disposed to produce magnetic dipoles transverse to the satellite spin axis such that by interacting with the Earth's magnetic field a torque is developed in a direction opposite the spin vector. The logic selects the proper magnetic dipole based upon data from sensors detecting the presence of the Earth for the development of the desired magnetic torque.

DEF

Euler’s equations : A set of three differential equations expressing relations between the force moments, angular velocities, and angular accelerations of a rotating rigid body.

CONT

Forced Precession. Consider now what happens when a rotating symmetric body is subjected to a torque. It is clear from Euler's equation that when the applied torque is parallel to the angular momentum, the body experiences an angular acceleration which changes the magnitude of the angular velocity but not its direction. However, that is where the analogy to the translational case ends. Strange as it may seem, the equation implies that the response of the rotor to a torque applied normal to the spin axis is to rotate in a direction normal to both the spin axis and the applied torque. This phenomenon is also called precession.

CONT

Gyroscopes in instruments usually are in the form of a wheel that is heavily weighted around the rim to increase angular momentum. The wheel is driven by an electric motor. Once the gyroscope has been set to spinning, its response to torques can be studied; it is then considered as a dynamic torque-measuring device.

Malheureusement, la précision de nos mesures est limitée par celle des appareils utilisés, tout particulièrement le tachymètre qui oscillait constamment aux alentours d'une certaine valeur.
