2.  Length: 99.875 inches  Diameter: 6.00 inches  Mass: 277.42 oz. / 17.34lbs.  Span: 13.50 inches  Center of Gravity: 56.3919 inches  Center of Pressure: 64.0575  Safety Margin: 1.28

3. Flight Sequence

4.  Dual Deployment ◦ Drogue chute and main chute  Black powder charges will be calculated using vernk.com and verified with ground testing

5.  Dual deployment system  Two MAWD altimeters used for redundancy ◦ Measures barometric pressure ◦ “Mach” delay for safety ◦ Deploys drogue parachute at apogee ◦ Deploys main parachute at 3000 ft AGL and payload parachute at 1000ft AGL  Will be programmed and Pre-tested for scale launch

7.  Airframe – carbon fiber ◦ superior strength to weight ratio ◦ Ease of workability  Fins – birch plywood in carbon fiber ◦ Combines the strength of both materials for a more rigid, strong, and lightweight fin  Bulk-Head/Centering ring – 0.5 inch birch plywood ◦ Cabinet quality grain, few knots, and locally available

8.  Nosecone ◦ Will be purchased to insure proper functionality  West Systems Epoxy ◦ Used to bind the above materials together as well as some hardware (bolts, nuts, threaded rods)

9.  Fins – symmetric shape and quantity allows for ease of construction, trapezoidal shape limits potential damage to fins upon landing  Diameter – 6” diameter allows for ease of assembly and plenty of work space. ◦ Also allows for better utilization of scrap components, and expansion of internal components if necessary

13. CritiqueScore 1/5 1 = Bad 5 = Good Comments Is this design safe?4This design will allow for ease of construction and eliminate safety concerns associated with more complex construction methods Is this design limiting? 4 Altitude is expected to be reached and the design will accommodate larger motors and payload components Does this design meet the requirements of the payload/rocket? 3This current rocket design satisfies the requirements for the projected payload. Will this design land safely? Parachute sizes, impact absorbing design? 4The current size rocket and parachutes have the rocket descending rapidly under drogue, but slowing to under 25 ft/s under main. Does this design maximize performance? 3The rocket has been designed to accommodate the payload as well as larger motors as the design is refined. Are the materials selected the best for this scenario? 4Carbon fiber is a strong yet lightweight material that we have had success with in years prior. Past experience with phenolic tubing has yielded structural failure. Any additional comments? -------Conduct additional tests and review plan to ensure continued safety

14.  Minimum velocity for stable flight: 25.63 ft/s  Exit rail velocity: 32.81 ft/s  A series of 3 rail beads will be used to ensure the rocket reaches adequate speed off of the rail while maintaining proper orientation

15.  A series of sub-scale launches are planned and will be conducted to verify design  Construction and test of the sub-scale will take place from 11/23-12/14  Planning for construction of full-scale starting 12/14  At least one test flight with the final rocket will take place

16. Justifications  54.0 mm diameter allows for easy down- scaling  Black Max Propellant provides the high visibility tracking of dense black exhaust Manufacturer:AeroTech Mfr. Designation:K513FJ Motor Type:reload Diameter:54.0mm Length:41.0cm Total Weight:1647g Average Thrust:556.8N Maximum Thrust:658.3N Total impulse:1496.3Ns Burn Time:2.8s

18.  The handling of the motors, including purchasing and assembly, will be under the supervision of our NDRA members.  North Dakota Rocketry Association (NDRA) Section #628  Certified NDRA team mentor: ◦ Dr. Tim Y. #76791 Level 2  We are planning to test fire the K513FJ motor in our static ground test. We are not planning a test of the sub-scale motor.

19.  Sub-scale launch – November 22 nd  Full-scale test flight #1 – February 22 nd to March 8 th  Full-scale test flight #2 – March 18 th to April 6 th  Final launch – April 10 th

20.  Rocket launch ◦ Reaching an altitude of 3000 feet at apogee.  Rocket recovery ◦ The recovery system deploying properly at the appropriate altitude and recovering the rocket on the ground such that it is deemed reusable for future launches  Payload ◦ The payload should be ejected from the rocket at 1,000 feet and return to the ground with its own parachute.

21.  Physics Day at UND - November 12, 2012  This is a program for local middle school to high school students to learn about the many different facets of physics. ◦ We gave a presentation about rocketry ◦ Introduced them to the USLI program and shared our past history with the competition ◦ Reached about around 200 students.

22.  Outreach at Grand Forks Area middle school  Our team is in the process of scheduling a date to visit the local middle schools. ◦ For an entire day, we will teach a science class. ◦ Give a brief lecture about rocketry ◦ Prior to us visiting, we will have the students design rockets out of 2 liter pop bottles. ◦ We will supervise and moderate the launch water rockets ◦ Have a Q & A session on why some rockets did work and other did not. ◦ Expect to reach about 30-80 students.

23.  Astronomy Talk  Scheduled for February ◦ Hour long lecture ◦ Aimed at introductory level astronomy students ◦ Content could include: History of Rocketry ◦ By the date of the talk, we might be able to give a demonstration of our AGSE
