Gyroscopic basics Flashcards
- Turn and bank indicator
- Directional gyro
- Gyro horizon (artificial horizon)
- Autopilot
- Drift meter
- Gyro stabilized fluxgate compass
- Inertial navigation system
Instruments that rely on a gyro for their operation.
Great weight for small size (high density)
Rotation at high speeds with low friction
Two important design considerations for a gyro instrument
Rigidity in space
A gyro when rotated at high speed will remain ______ in the plane in which it was spinning
rigid
Precession
If a force is applied to a spinning gyro, its effect will be felt at a point ______ degrees from the point of application
90 degrees
The rigidity is _______ as the mass at the rim of the gyro wheel is increased and as the speed of rotation is increased
increased
The _________ properties of a spinning wheel have made precision instrument flying precise navigation, and pinpoint bombing practical and reliable.
Gyroscopic
A _______ is a pivot point (mountings) that allow the gyro to rotate about its axes. They may be circular rings, rectangular frames, or in flight instruments.
Gimbal
indicates the number of directions in which the gyros rotor can move.
Explain the term ‘planes of freedom’
indicates the number of directions in which the gyros rotor is free to move. This disregards the gyros spin axis.
Explain the term ‘degrees of freedom’
The number of gimbals is EQUAL to the numbers of ______.
degrees of freedom
The Gimbaling system isolated the ______ from the base rotation (in out case, the aircraft’s rotation)
ROTOR
2 General types of mounting for gyros:
Free (Universal)
Restricted (Semi-Rigid)
The tilting force that causes a gyro to precess is called a ______.
torque
Type of mounting that is free to move in all direction.
Used in directional and attitude gyros
Free (Universal) mount
Type of mount that is commonly known as RATE GYRO
One of the plane of freedom is held fixed in relation to the base.
Restricted (Semi-Rigid)
