The power source for such a gyroscope is typically an integral electric
motor but may also be a stream of air. Regardless of the power source,
a figure of merit for a gyroscope is what is known as ``coast time'',the
time for a gyroscope spinning at full speed to slow to a stop whenits
power source is removed. For example, a 16 minute coast time is
B. F. Goodrich manufactures a wide variety of flight information systems,
among which are gyroscope based attitude indicators; typical of these
is the Model XYX.
Recently the suspension bearings of the Model XYX were improved,
increasing the life expectancy of the XYX from 3000 hours to 20,000
The goal of this project is to predict the remaining useful life of
new and/or used gyroscopes.
A variety of data taken from new and used gyroscopes are available for
analysis. Some of this data is life test data used to predict the lifeexpectancy
of the original and improved XYX gyroscopes by simple rules of thumb.
In addition, the customer service department tests and records thelow
speed torque requirement and the 22,000 RPM vibration spectrum of
gyroscopes returned for service (returns are not necessarily prompted
by time in service or gyroscope mechanical problems).
The ideal completed project deliverable would be a test specification
and algorithm for predicting the remaining useful life of an XYX model
gyroscope from spectral and torque data.
