Gyroscopic instruments Flashcards
1
Q
The gyroscope
A
is a rotor or a spinning wheel rotating at high speed in a universal mounting called a gimbal in such a way that its axle can be pointed in any direction
2
Q
Parts of a gyroscope
A
- Gyro
- Gimbals
- Gearing
3
Q
Gyroscopic principles
A
Gyroscopic precession
Rigidity in space (gyroscopic inertia)
4
Q
How are gyros powered?
A
- Electrically Powered system
- Engine-Driven Vacuum System
- Venturi Driven Vacuum System
5
Q
The suction gauge
A
- Green Range – Normal Operating Range (4.6-5.4)
- Low pressure – inaccurate indications
- High pressure – damage to gyros
6
Q
Ring Laser gyro
A
an optical gyroscope that measures angular velocity using the Sagnac effect. It utilizes two laser beams propagating in opposite directions around a closed path (usually a ring) and measures the difference in their travel time, which is directly related to the rotation rate.

Q
mems gyro
A
measure angular rate by means of Coriolis acceleration.
