There are six basic quantities that require measurement and instrumentation relevant to aerospace vehicle propulsion units, plus a host of secondary and tertiary parameters. In this chapter, only these six primary quantities will be considered because the plethora of others are specific to each type of vehicle, so are better treated in individual papers and similar publications.
These six basic parameters are fuel quantity, fuel flow, pressure, temperature, rotational speed, and vibration; fundamental methods for measuring each are presented below. Whether or not a sensor based on a given method ...
