Justin Silva (RIT Student) Write MATLAB script for losses in fuel line.	8/2/2020	8/10/2020	8/6/2020	Code is partly written, but valves and piping properties need to be replaced with those of the parts used in RL-36.	Since flow rates are very low for the piping size used throughout the feed system, losses are minimal. At higher flow rates, such as in future, higher-thrust engines, these losses become significant.
Justin Silva (RIT Student) Write MATLAB script for high-pressure gas tank pressurization.	8/2/2020	8/10/2020	8/31/2020	Code is partly written but needs pressure downstream of fuel tank to be calculated first.	Nitrogen tank can be pressurized to 1000 psi. This accounts for the ullage volume that need to be pressurized when nitrogen flows into fuel tank. This will not have a great impact on flow rates, and it requires a purchase of 20 kg of nitrogen gas.
Derek Basta (RIT Student) Investigate combustion chamber geometry and update CAD.	8/2/2020	8/9/2020	8/8/2020	Ensure design conforms to established theory and is as easy to manufacture as possible.	According to RPE, converging nozzle section "has never been critical in achieving high performance," therefore we can continue to adjust it to whatever is easiest to manufacture. Justin Silva (RIT Student) suggested making the chamber area 3x the throat area; current chamber area is 25x throat area. This change would make the engine significantly smaller than current design, further discussion should take place.
Derek Basta (RIT Student) Add renders of engine components to website.	8/2/2020	8/16/2020	8/16/2020		Added renders of exploded engine assembly and test stand. May add more renders in future. Also, renders will have to be updated after final design changes.
Justin Silva (RIT Student) Write MATLAB script for losses in oxidizer line.	8/9/2020	8/18/2020			Due to very low flowrates, the losses in the oxidizer line are negligible.
Justin Silva (RIT Student) Run CEA for gasoline fuel and updated area ratio.	8/29/2020	8/31/2020	8/31/2020		Doing CEA analysis with gasoline is very difficult because the chemical composition of gasoline is not available to the public. Gasoline is a mixture of dozens of hydrocarbons, and the ranges for percent composition by weight are wide.
Justin Silva (RIT Student) Brahm Soltes (RIT Student) Update BOM based on feed system components that team either has or needs.	8/29/2020	9/5/2020	8/31/2020		Five adapters in the nitrogen line were traded for two more simple adapters. A total of eight new adapters are needed to fill remaining gaps in all lines.
Justin Silva (RIT Student) Take oxygen and nitrogen tanks to Airgas to find out what kind of shutoff valves can be placed on the tanks.	8/31/2020	9/12/2020			Airgas account is set up. COTS tanks will be used to fill the custom tanks. Sizes and pressures for COTS tanks have been calculated. Both oxygen and nitrogen tanks will be 200 cf at 2000 psi.
Justin Silva (RIT Student) Create annual budget proposal.	10/11/2020	10/18/2020	10/17/2020		Budget proposal was presented and approved at leads meeting.
Justin Silva (RIT Student) Create cold-flow test procedure.	10/18/2020	10/26/2020	10/26/2020	Include how tanks will be used, which pressurizing gas will be used, and how combustion chamber will be secured inside bunker.	Went over cold flow procedure with Jim Heaney.
caw5317 Program control system.	2/13/2021	2/22/2021		Program igniter and solenoid valves so that they can be ethernet controlled from outside of bunker.
Derek Basta (RIT Student) Write introduction to technical report.	2/13/2021	2/22/2021
Justin Silva (RIT Student) Write feed system layout part of technical report.	2/13/2021	2/22/2021		Should include why certain valves were placed where they are in the system, as well as P&ID diagram.
