System Overview Presenter name here 5
Mission Summary Overview of mission objectives Include any external objectives 6
System Requirement Summary Overview of system (mission) level requirements Use bullets or table to demonstrate understanding of requirements Include requirements for the rover Include requirements for the rocket 7
Changes since PDR Identify all changes since PDR in overall design 8
System Level Design Present selected overall design concept Configurations of rocket and rover This is a overview of the design concept 9
System Concept of Operations Provide overview of operations of the system from launch to landing to rover operations. Launch and descent operations Robot operations Post-launch recovery Simple flow diagrams and cartoons are a good way to present the CONOPS 10
Rocket Design Presenter Name 11
Rocket Changes since PDR Identify all changes to the rocket design 12
Overview of Rocket Describe overall rocket design A drawing of the rocket identifying all of its components and dimensions Length and diameter Identify major components and locations Nose cone Number of fins and size Location and size of rail buttons Location of avionics bay if using electronics deployment with altimeter(s) Total on the pad weight of the rocket with the primary and backup motors. This includes: All recovery harnesses and parachutes Primary or backup motor Rover 13
Design of Rocket (continued) Identify the rocket s stability. The center of gravity (CG) must be ahead of the center of pressure (CP) by at least one diameter (caliber) of your rocket. With primary motor With backup motor Motor retention method Friction fit is specifically disallowed Explain how the rover is stowed and deployed from rocket 14
Rocket Materials List of materials used: Airframe material Fin material Nose cone material Type of adhesives used Rail button source and material 15
Rocket Recovery System Parachute selection Size of and how determined Identify method for protecting parachute and rationale for choice Dual deploy? What is the expected descent rate(s) Harness Show drawing of recovery harnesses for each part of rocket Type of shock cord, lengths and strengths Identify linkages and load limits Attachment points, eyebolts, fender washers, etc. and their mounting methods 16
Rocket Recovery System Deployment Method Document method of initiating recovery Altimeter(s) Parachute release mechanism Motor ejection - specify motor delay in seconds for Primary motor Secondary motor Any rockets using VMAX motors must use an altimeter that deploys the parachutes as per Tripoli and NAR rules. 17
Rocket Recovery Electronics - if used Identify which commercial altimeter(s) will be used Show wiring diagram of altimeters with charges Document the number and size of the pressure ports for altimeter Document altimeter preparation steps. Specify the quantity of black powder to be used to separate each section Specify the volume of the section to be pressurized with calculated pressure level Document charge size testing and results Specify how sections are secured before the ejection charges separate sections friction fit shear pins - number and size Other Identify how charges are fired e-matches other 18
Altitude Recording Altimeter Identify the commercial altimeter to be used to officially record the rocket s altitude If using a commercial altimeter for deployment, it can be designated as the altitude recording altimeter 19
Rocket Motor Selection Identify primary motor selection Calculate thrust to on pad weight ratio using average thrust of the primary motor Thrust to weight ratio must be a minimum of 5:1 Identify back up motor selection and what changes to rocket would be required to successfully comply with contest rules Calculate thrust to on pad weight ratio using average thrust of the backup motor Thrust to weight ratio must be a minimum of 5:1 Include a simulation plot for the primary motor Include a simulation plot for the backup motor 20
