Gyros Flashcards
Name the 2 behaviours of a rotating mass?
Rigidity and precession
What can increase the stability of a Gyro?
Increasing the Mass or Speed
What speed do the Vertical (attitude) gyro and Directional (heading) gyro spin?
15,000 rpm and 10,000 rpm respectively
A gyro is distorted, in which direction will it deflect?
90 degrees from the point of application in the direction the wheel is spinning
Precession is not desired in directional and vertical gyros but may be used in a?
Rate gyro because the amount of precession is related to the amount of force that caused it.
How many degrees of freedom does a vertical and directional gyro have?
2
How many degrees of freedom do a rate gyro and rate integrating gyro have?
1
What is a vertical gyro used for?
Pitch 85 Degrees and Roll 360 degrees indication
In what ways can the vertical gyro be erected?
Air Driven, Electric Driven or with two small steel balls
Apparent Drift is caused by?
The earths rotation
What is the earth rotation?
15 Degrees and hour
At which point on earth does a vertical gyro have maximum apparent drift?
At the equator
At which point on earth does a directional gyro have maximum apparent drift?
At the poles
What instrument is a rate gyro used in?
Turn and slip indicator
The bank angle of a correct flown aircraft depend on?
The speed of the aircraft
