7 Parachute and Descent Rates  Rocket mass = oz  Drogue chute diameter = 24 in.  Main chute diameter = 84 in.  Calculated projected velocity for each chute with online calculator and by hand  v 2 = 2F D / (ρ)(C D )(A) C D = 1.00C D = 1.00 F D = mg = (6.285 kg)(9.8 m/s 2 )F D = mg = (6.285 kg)(9.8 m/s 2 )  Hand: v drogue = ft/s Online: v drogue = ft/s  Hand: v main = ft/s Online: v main = ft/s 7 Student Launch Initiative AIAA OC Section

8 Dual Deployment  Electronics: MAWD Perfect Flight, HCX G-Wiz Partners  The electronics will “back” one another up incase one pyro (either drogue or main) does not fire.  Drogue Parachute will be deployed at apogee  Main Parachute will be deployed at 900ft  The electronics have been tested four tests have been done: Christmas tree light testChristmas tree light test Vacuum Chamber testVacuum Chamber test First flight in the scale rocket (MAWD Only)First flight in the scale rocket (MAWD Only) Second Flight in scale model (MAWD Only)Second Flight in scale model (MAWD Only) 8 Student Launch Initiative AIAA OC Section

10 Payload  G-Wiz Partners HCX flight computer - measures acceleration of the rocket  Toshiba hard drive – test subject; we will run a Linux script on the hard drive over and over again; the time the hard drive takes to run the script each time is measured  Simple net computer/Linux computer – the mini computer that will execute the Linux script on the hard drive; it will be initialized by a PC; the flight data will be recorded on a flash drive inserted into this computer  Power converter – Keeps a steady flow of power to the payload components 10 Student Launch Initiative AIAA OC Section

11 Test Plans and Procedures  February 12 launch Scale model Test dual Deployment  Ejection charges Full Scale model Test with modified ejection charge amount  Launch Scale Model March 5 and/ or March Student Launch Initiative AIAA OC Section

14 Scale Model Second Flight 14 Student Launch Initiative AIAA OC Section

15 Flight Analysis After watching the flight we knew there was some faults: 15 Student Launch Initiative AIAA OC Section FaultWhy it was madeHow we are going to fix it Complex wiringThe team was trying to fit everything in the avionics bay, and didn’t have much room Make Longer wires to be able to assemble sleds outside of the avionics bay and slide in Instability when reaching apogee Team rushed to get one more flight in Ultalize time more wisely, and not look over look any ‘small’ detail Drag/impulse SeparationA mentor advised not to use shear pins for main ‘chute Follow the design and don’t let others misguide you

16 Testing  All the testing we have done is to help ensure that our rocket is safe  Testing that has been done includes: Black PowderBlack Powder Battery LifeBattery Life GPS RangeGPS Range Scale Model LaunchScale Model Launch 16 Student Launch Initiative AIAA OC Section

17 Testing – Black Powder The table below shows the testing our team has done with black powder charges. How we did the testing was by assembling the rocket as we normally would but through the pressure hole 17 Student Launch Initiative AIAA OC Section

18 Testing – Battery Life 18 Student Launch Initiative AIAA OC Section

19 Testing – GPS Range   Our team first let the electronics connect to satellites, once it had done that then we started to walk away from the transceiver (big red bee beeline) and saw how far it would transmit while being in the rocket. 19 Student Launch Initiative AIAA OC Section

20 Educational Outreach  Cloverdale 4-H club  Girl Scouts workshop  Presentations to Sunny Hills High School Science classes to get involved  Help out ABC Unified School District with their annual Science Olympics  Articles published/ will be published in the Orange County Register, The Foothill Sentry, and the Sunny Hills High School Accolade  We have contacted the Discovery Center to participate in their Youth Booth  In the process of contacting corporations regarding fundraising 20 Student Launch Initiative AIAA OC Section
