Booster Vision Sub-System Monitoring = James Levine (*The AGTS system will be integrated into the rocket depending on final weight of the rocket. However, as seen in Vehicle Criteria- Section A of the FRR Report, the flight on April 9th, had a very close landing in proximity to the launch pad. (**We will have a Walston Tracking system for the flight vehicle by the time the team is ready for the SLI Trip.) Then, the team will bring back the payload section and the flight vehicle section, move the data into non-volatile memory and try to download the data onto a laptop computer for safe keeping. We will also slide out the payload and take a picture of the cobalt salts so that the image can be analyzed later. The flight vehicle and payload will then be inspected for any damage that would need to be repaired for another flight. Phase 4: Data Retrieval 5
    • The data collected during flight will go through a series of procedures through the TI-89 Titanium Calculator in order to move the memory from flash to standard RAM4 non- volatile memory so that the disconnection of power will not damage the data. This is for precautionary purposes. Then the LabPro will be hooked up to a computer for full data retrieval. We would connect each LabPro to a computer through the USB5 2.0 port on the LabPro and then would use LoggerPro 3.3 to download the data for viewing and analysis. The data collected through the Parallax Humidity and Temperature System (PHATS6) will be connected through the USB cord to a computer where it will be downloaded so it can be analyzed at a later time. The same will be done with the iTX system, but it will be connected through a slightly different cord arrangement (USB to Industrial Scientific converter box to the iTX). Time will also be recorded (with the same watch that recorded when it was tuned on) when the iTX is turned off so that it can determined which part of the graph corresponds to the launch time. Detailed procedures for the data retrieval process (the non-volatile memory switch and LoggerPro 3.3 download) are in Part 3 – Section F of this Report. PART II: Flight Vehicle Operation Procedures Section A: Flight Vehicle Recovery Preparation 6
    • When prepping the rocket it is important to slow down and prioritize on what needs to be down at what time goal. The goal of recovery preparation is to make sure that the rocket comes down safely; making sure that the flight will not harm the rocket, payload, or any team members as well as spectators. Step 1: Lay out all of the equipment necessary for recovery preparation. Recovery preparation also includes the use of the flight computers. Since the Payload Team will be busy prepping the payload systems. The recovery team will have prerogative over the preparation of the payload parachute, though it is a subsystem of the payload. List of Necessary Equipment for Recovery Preparation: Quantity: 4 of (1/4 inch thick) Steel Quick Links 1 Inch Kevlar Strap for the Main Parachute 1 inch Kevlar Strap for the Drogue Parachute Payload Spherachutes Deployment Bag Flight Vehicle Spherachutes Deployment Bag SkyAngle Classic 36 inch Drogue Parachute Payload Spherachutes 168 inch Parachute Flight Vehicle Spherachutes 168 inch Parachute Pull “Screamer” (the black box one. Rated at: 110db) Transolve Transbeep Light Activated Screamer (Rated at 90db) Shear Pins Quantity: 8 of (1/4 inch thick) Stainless Steel Bolts Quantity: 4 of Pyro Charges Canisters* Black Powder** Modeling Clay Masking Tape Electric Tape Extra Wire & solder Rubber Bands (if necessary) Tools: Regular and Needle Nose Pliers Wire Stripper Tool Soldering Iron Phillips and flathead screwdrivers Drill and Proper Bits (if necessary) 7
    • --List for Recovery Sub-System Preparation Phase-- □ Pyro Charges Connected □ Fold and pack drogue parachute □ Fold and pack Payload Spherachute 168” in deployment bag □ Fold and pack Flight Vehicle Spherachute 168” in deployment bag □ Organize all shock cords to ensure proper placement □ Run shock cords through pistons and caps □ Attach quick links to designated ends of shock cords □ Attach drogue parachute to quick link □ Attach screamer to quick link □ Attach main parachute to avionics bay □ Attach deployment bag to 168’’ Spherachute □ Attach Spherachute to payload □ Attach all shock cords and check □ Make sure all quick links are attached and tight □ Bolt into T-nuts □ Place in sheer pins Section B: Propulsion Preparation – Overall Motor Assembly The Motor must be only assembled by the National Association of Rocketry (NAR) Mentors associated with the team (Gabe Kolesari, Charles Marks, and Scott Goebel). Mr. Kolesari, Mr. Goebel, or Mr. Marks because of their level 2 certification with the National Association of Rocketry, will be the only people assembling and or handling the motors. Because of the rules against students handling black powder, Charles Marks and/or Mr. Goebel or Mr. Kolesari will also be the only people that will be handling the pyrotechnical charges that are an integral part of the recovery system for the rocket. This is why one of the mentors will oversee the recovery preparation where the charges will be prepared and connected to the flight computers. □ Load central 75mm motor into the rocket □ Load outboard 38mm motors into the rocket □ Tighten motor retention to ensure that motors are secure Section C: Propulsion Preparation – Ignition System and Igniter Preparation 8
    • Again, because of the restrictions on students handling the motors the mentors associated with the team will be the only people that can prepare the igniters for the propulsion. Because of past experience, Mr. Gabe Kolesari (NAR Level 2) will be preparing the igniters for the rocket. Because we are using the G-Wiz clustering feature on this year’s rocket, before launch, the igniters will be connected to the G-Wiz and then forced through a tube which will come out the bottom of the cluster where the wires can be strung to the appropriate motors when the rocket is on the pad. □ Check igniters for resistance to ensure that they are working properly □ Feed Clustering igniters down to the outboard 38mm Motors □ Connect Wire to G-Wiz □ Connect G-Wiz Power Supply □ Set function on the G-Wiz □ Place G-Wiz into avionics bay □ Test G-Wiz to make sure functions are operating properly □ OUTBOARD MOTORS AVIONICS PROCEDURES FINISHED On the Pad □ Re-ensure that motor retention is in place □ Carefully feed igniters into the motors* □ Tape down the wires from the igniters □ Check igniter installation integrity □ SSO and Safety Director Confirm Ignition system is “safe” (*Mentor Restricted Step - Handling of all pyrotechnic materials that would classify as hazardous material) Since we will be using a cluster, Mr. Gabe Kolesari will also be preparing the motors so that all of the motors will ignite off the ground and will pressurize within the proper timeframe so that the rocket will launch as planned. More information can be found in this overall FRR Report under Vehicle Criteria Section C. Section D: Flight Vehicle Ground Stabilization System (Launch Pad) The launch pad that will be used is a trailer pad design. It has the ability to launch rockets up to 400lbs and will have a 24 foot long rail guide that is able to handle our rocket 9
    • length. Team members James Levine and David Werner will be in charge in setting up the launch pad. Section E: Overall Flight Operation Procedures and Checklists USM SLI Master Launch Checklist (Details of Phase 2 Flight Vehicle Launch Operations) Pre-Prep: □ Ground Control Center Set □ Video Camera 1, 2, 3, 4 Set □ Video Camera Pad Cam 1 Set □ Video Camera Pad Cam 2 Set □ Medium Distance Video Camera Set □ Launch Pad Set - Flight Vehicle Launch Preparation Checklist - Recovery: □ G-Wiz MC Set - Make sure that it is a new battery - Make sure that the MC switches are properly set - Ensure that the wires are connected properly to the MC - Ensure MC is not “armed” after prepped and that it is in “standby” mode □ RRC2 Set - Make sure that it is a new battery - Make sure that the RRC2 switches are properly set - Ensure that the wires are connected properly to the RRC2 - Ensure RRC2 is NOT “armed” after prep. and that it is in “standby” mode □ Pyro Charges Connected □ Fold and pack drogue parachute □ Fold and pack Payload Spherachute 168” in deployment bag □ Fold and pack Flight Vehicle Spherachute 168” in deployment bag □ Organize all shock cords to ensure proper placement □ Run shock cords through pistons and caps □ Attach quick links to designated ends of shock cords □ Attach drogue parachute to quick link □ Attach screamer to quick link □ Attach main parachute to avionics bay □ Attach deployment bag to 168’’ Spherachute □ Attach Spherachute to payload □ Attach all shock cords and check □ Make sure all quick links are attached and tight □ Bolt into T-nuts 10

Section I: Media and Documentation Equipment setup Procedures and Plan 12
    • There will be a series of camera around the launch pad to capture every angle of the flight as well as help us visually analyze the deployment of the parachutes to ensure that the recovery design is correct. Currently we have 7 video cameras that will be facing the rocket and 1 still camera. We will have 4 video cameras (Marks Home Camera held by James Levine, Ahmad Home Camera held by Jawaad Ahmad, Goebel Home Camera held by Mr. Goebel, Greaves Home Camera held by Mr. Greaves) that will be guided by people holding them, 1 medium distance video camera on a tripod (Ahmad 2nd Home Camera), 1 upward facing pad cam inside a protective lexan box (Greaves 2nd Home Camera), 1 pad camera (Bishop Home Camera), and a Booster Vision On-Board Camera System (OBCS) that will broadcasting on-board video during the rocket launch. Spencer Greaves will be using his Nikon D70s to capture still shots of the rocket during its flight. Note: The number and positions of cameras that will be documenting the rocket’s launch is not a vital part of the success of the flight. Rather, it is just for documentation purposes. A preliminary diagram of the camera positions is below. Part III: Scientific Payload Operation Procedures 13
    • Section A: Pre-Flight Payload Setup Procedures The payload must be assembled and ready so that it can be easily inserted into the payload airframe and properly armed for launch. These steps are the Pre-Flight Payload Setup Procedures. In this the sensors and the LabPro systems are mounted on to the payload pallet and the entire payload pallet system us prepped and ready to be armed. Below is a list of Pre- Flight Payload Setup Procedures. ADD related Payload Sub-Systems □ Load LabPro “Blue” into Payload Pallet □ Load LabPro “Gold” into Payload Pallet □ Mount CO2 Sensor inside ADD7 □ Connect ADD hose to Gas Pressure Sensor □ Mount Temperature Sensor □ Mount Accelerometers □ Mount iTX and test sub-system to ensure that it is working properly □ Load Cobalt Salt Plate into the ADD □ Connect Temperature Sensor to proper LabPro and hot glue into place □ Connect 3 Axis-Accelerometer to LabPro and hot glue into place □ Connect 25g Accelerometer to LabPro and hot glue into place □ Connect CO2 sensor to LabPro and hot glue into place □ Connect Gas Pressure Sensor to LabPro and hot glue into place □ Connect Barometer to LabPro and hot glue into place □ Load Batteries into Power Supply Packs □ Connect Power Supply to LabPro □ Go through arming procedures to ensure that the LabPro is working properly □ Re-set to Standby mode □ WHEN ALL OTHER PAYLOAD PREPERATION STEPS ARE COMPLETED: turn on the iTX [make sure that the 4 stopwatches are set when the iTX is turned on. Two will be shutoff when the rocket launches, the other two when the payload hits the ground. Christian Bauzenberger (Stopwatch 1), Colin Weber (Stopwatch 2), David Werner (Stopwatch 3), William Bishop (Stopwatch 4)]. PHATS (Parallax Humidity and Temperature Sub-System) □ Mount Parallax Board and Connect Power Supplies □ Ensure HOBO is connected to □ Use Bluetooth “ToothPic” system to setup program on Parallax □ Go through arming procedures to ensure that Parallax is working properly Section B: Pre-Flight Avionics Setup Procedures 14
    • The Pre flight avionics setup procedures mainly includes the setup of the AGTS system and the FC-877, a accelerometer based recording flight computer which will be linked to the AGTS system to give the USM SLI real live flight data in the form of a data uplink between the AGTS system and a system on the ground. □ Mount the AGTS to the Payload Pallet □ Mount the FC-877 to the payload pallet. □ Connect the battery supply to the AGTS system. □ Connect the AGTS system (serial RS-232 port) to the serial port on the back of the computer. □ Setup 877 (pyro outputs 1-4 are disabled & acceleration based apogee detect) □ Ensure that the AGTS and FC-877 are working simultaneously and in conjunction with each other -Commence Pre-Flight Operations Calibration and Uplink Check Phase- □ Using the CATS8 system software, check the uplink status and make sure that the AGTS address and module setup function* is operational. (*Make sure that there is no-one in the area flying a rocket on the same model frequency or the lock on the AGTS may be lost during flight). □ Using CATS: Set Network Address □ Using CATS: Set Code □ Using CATS: Check Signal Strength □ Using CATS: Ensure that the AGTS is properly programmed □ Using CATS: Ensure that the AGTS is broadcasting correct positional data □ Mark down the launch coordinates and enter waypoint into GPS “Garmin eTrex Legend” to ensure that there is a low reading discrepancy between the AGTS and the handheld GPS system. At the Launch Site: □ Arm the FC-877 □ Arm the AGTS □ Check AGTS Broadcasting Signal □ AVIONICS ARE GO FOR FLIGHT Section C: Pre-Flight Outreach Program “mini-payload” Setup Procedures 15
    • - Remove Outreach Payload from the nosecone (un-screw 3 #8 screws from T-Nuts) - Cut zip-ties and remove canister - Insert crickets into canister - Re-position canister and zip-ties - Arm LabPro and begin data collection - Mark time for when LabPro was armed. Section D: Pre-Flight Booster Vision On-Board Camera System Setup The booster vision ground station will be connected through and inverter which will directly connected to a Macintosh PowerBook and will be imported directly to the hard drive using iMovie. The Booster Vision Camera will broadcast its signal on 2400 MHz to the ground station. Booster Vision On-Board Camera System Setup Steps for USM SLI Launch This step will be that last step that will be completed before the launch sequence is initiated. □ Make Sure Camera is facing downward at the right angle □ Check all wiring connections □ Install the Nosecone on top of the rocket □ Arm OBCS □ Check OBCS Broadcasting Clarity Section E: Flight Payload Procedures – Software Prep Operations 16

    • □ Payload Ready Section G: Overall Post Flight Procedures – Data Analysis and Recovery After the data has been collected during launch, the LabPro will be connected to the calculator and the data in the flash memory will be moved into a safe memory area known as Standard RAM. This memory port is a non-volatile memory port that will store our data just in case we have a sudden power failure or another problem that would make us lose the data we collected during the launch. Then the LabPro will be connected through the USB port on the LabPro to the USB port on the computer. Then the data will be downloaded to a software program known as LoggerPro 3.3 for analysis. The data collected through the Parallax Humidity and Temperature System (PHATS10) will be connected through the USB cord to a computer where it will be downloaded so it can be analyzed at a later time. The same will be done with the iTX system, but it will be connected through a slightly different cord arrangement (USB to Industrial Scientific converter box to the iTX). Time will also be recorded (with the same watch that recorded when it was tuned on) when the iTX is turned off so that it can determined which part of the graph corresponds to the launch time. Section H: Risk Mitigation and Analysis There are many things that can go wrong with our payload because of the fact that it is very complicated. That is why we have this extensive procedures list for the preparation of the payload and flight vehicle. Some possible problems that could occur are listed on the next page. 20
