| 12 | 1 | J. Simmons | |
| 13 | 3 | Aaron Harper | *BA2.* Undergraduate aerospace and high level high school students and Mach30 Volunteers. |
| 14 | 1 | J. Simmons | |
| 15 | 1 | J. Simmons | h3. BQ3. How will this be used? |
| 16 | 1 | J. Simmons | |
| 17 | 4 | Aaron Harper | *BA3*. Demonstrate fundamentals of propulsion systems design and testing of a cold gas thruster to include thrust, specific impulse, expansion ratio, chamber pressure, throat area, and controls. |

| 24 | 1 | J. Simmons | |
| 25 | 1 | J. Simmons | h3. TQ1a. What features does it need to have (now)? |
| 26 | 1 | J. Simmons | |
| 27 | 1 | J. Simmons | *TA1a.* _The project needs to:_ |
| 28 | 1 | J. Simmons | |
| 29 | 7 | Aaron Harper | * The thruster components from expansion chamber to nozzle are modular to allow experimentation and projects to be tested using the same hardware and parameters. |
| 30 | 7 | Aaron Harper | * Includes a set of sample CAD models for modification (templates) |
| 31 | 7 | Aaron Harper | * Gas flow must include a tank of fixed volume, pressure gauge, electrically actuated valve, and timing circuit to make comparison of designs possible. |
| 32 | 7 | Aaron Harper | * Must be operable indoors |
| 33 | 7 | Aaron Harper | * Control system must be integrated with test stand controls for synchronization and testing. |
| 34 | 1 | J. Simmons | |
| 35 | 1 | J. Simmons | h3. TQ1b. What features does it need to have (later)? |
| 36 | 1 | J. Simmons | |
| 37 | 1 | J. Simmons | *TA1b.* _In the future, the project (or related projects) may need to:_ |
| 38 | 1 | J. Simmons | |
| 39 | 7 | Aaron Harper | * Variable gas flow for throttling |
| 40 | 7 | Aaron Harper | * Variable time valve operation for pulse width modulation and flow characteristics. |
| 41 | 7 | Aaron Harper | * Demonstrate ideal expansion, under- and overexpansion characteristics. This may require flow visualization capability (schlieren and/or CO2 vapor) |
