DAQ Test #1: Oven Test

Test Breakdown

Date to be conducted: 3/16/2019

Test Article: Test NC, from layup #1

Benchmark	Test Config.	Criteria for Success
I. DAQ must be continuously operational under [TBD] F, [TBD] C	NC is mounted on a test jig to isolate it from the floor of the oven DAQ is mounted on a test jig to isolate it from the floor of the oven	Records accurate temperatures (within expected 5 degree error, or allowable by reason) in SD Card and NAN Flash Memory for 8 min
II. Determine approximate thermal boundary conditions between inner wall and outer surface of NC at one selected node point	NC is mounted on a test jig to isolate it from the floor of the oven DAQ is mounted on a test jig to isolate it from the floor of the oven NC is plugged on both ends with insulation	Records accurate temperatures for the node point (within expected 5 degree error, or allowable by reason) in SD Card and NAN Flash Memory for 7 min
III. Epoxy joints must survive continuous heating up to 8 minutes	Same as above	Sensor leads must feel secure when tugged after continuous heating.

Conclusions:

Oven Temperature Tracking:

5:30 -> ~130 F

3/13/2019 (Diane, Miske, Juan):

Brought test NC w/ 6 thermocouples installed from lab to oven room in basement of 37
Discussed and outlined Oven Test above
"Wool" insulation, nose cone mold for support, foam cut outs for support, test for thermal coefficient, test for daq nominal operation

3/16/2019 (Diane, Miske, Juan):

Used four (4) masonry blocks to support NC in oven
Used normal PVC insulation wire for power, route through thermocouple inlet
Mounted daq with Kapton tape on a masonry block
Created a NC template of the top and base of the NC by marking a trace on the insulation
Added Kaowool (ceramic based) insulation inside the base and top of the NC prior to oven insertion
Discussed preheating oven to 257 F (125 C) before powering on
