Abstract:

The fuel mass flowmeter system demonstrated in a previous Army program, consisting of an ultrasonic flow velocimeter and a capacitance-type densitometer, was adapted to T-700 gas turbine engine requirements. Mechanical adaptations included the reduction in size and weight of the flow cell to fit the configuration and mounting constraints of a T-700 engine. Electronic developments included repackaging into a portable field-type case, configuration switching and digital delay equalizers, and the substitution of a microprocessor for a previously used calculator chip, resulting in a choice of response times, or integration times, selectable from approximately 50s down to approximately 0.5s.
