Tamara - look into combustion simulation (Rpa emailing for full license, contact burnsim) , email GTL regarding thermal camera.
Jorian - nail down percentages of aluminum boride, find suppliers
...
Lee - magnesium boride
Simulation update:
- NASA Software requires higher level access, self verification with social security number. (Thoughts?)Jorian requested NASA RoCETS software.
- Emailed Zolti for suggestions, no response yet, thermal camera in GTL, burnsim recommended.
- Flow 3D could be viable, has free academic license but needs to be installed department wide- possibly negotiable over email though.
- Propep (used before)
- There are combustion temperature equations that we could theoretically code but that's a lot of work.

Need to find a way to test propellant burning in vacuum. try to find professional solid prop person to ask about how to simulate this/do appropriate testing
Notes on plasticizers:
- IDP is the overall best plasticizer. There are different plasticizers with slightly better mechanical properties, but are much more difficult to process. (https://d11fdyfhxcs9cr.cloudfront.net/templates/170652/myimages/plasticizers.pdf)
- Increasing percentage of IDP improves processability and pot life. (https://d11fdyfhxcs9cr.cloudfront.net/templates/170652/myimages/plasticizers.pdf)
Looked into an alternative to HTPB: PBAN (used on NASA boosters). But PBAN is more difficult to mix, and has similar performance. (https://www.nasa.gov/returntoflight/system/system_SRB.html) (http://www.braeunig.us/space/propel.htm#:~:text=PBAN%20formulations%20give%20a%20slightly,more%20flexible%20than%20PBAN%20binder)
We can decrease burn rate by including a suppressant, such as oxamide (which should not impact performance). (https://www.nakka-rocketry.net/burnrate.html)
