Brayton Cycle Experiment – Jet Engine - Turbine Technologies

Instrumentation.
The sensors are routed to a central access panel and interfaced with data acquisition hardware and
software from National Instruments. The manufacturer provides the following description of the
sensors and their location.
“The integrated sensor system (Mini-Lab) option includes the following probes:
Compressor inlet static pressure (P ), Compressor stage exit stagnation pressure
1
(P ), Combustion chamber pressure (P ), Turbine exit stagnation pressure (P ),
02 3 04
Thrust nozzle exit stagnation pressure (P ), Compressor inlet static temperature
05
(T ), Compressor stage exit stagnation temperature (T ), Turbine stage inlet
1 02
stagnation temperature (T ), Turbine stage exit stagnation temperature (T ), and
03 04
thrust nozzle exit stagnation temperature (T ). Additionally, the system includes a
05
fuel flow sensor and a digital thrust readout measuring real time thrust force based
upon a strain gage thrust yoke system.”
