pressure: 95” from nose• Location of center of gravity:

76” from nose• Thrust to weight ratio: 11.25• 4.85 calibers of stability

Materials• All body components

are made of fiberglass• Kevlar shock cords• Nylon Parachute

Vehicle Summary

Vehicle

• Collaborate with NAR member throughout the entire construction process

• Multiple computer simulation will be analyzed to ensure rocket performs as desired and in a safe manner

• Ground tests will be conducted to verify optimal performance of recovery system and subsystems

Motor Selection

• Aerotech 54 mm K828FJ reloadable motor• Altitude optimization tests performed in

OpenRocket to reach 5,280 feet

Motor Selection

Motor Safety

• Motor will be purchased by overseeing NAR member and he will be present during all handling of motor

• Store materials in proper containers• Wear proper protection when handling• Inform all team members of proper handling

procedures and have MSDS sheets readily available

Payload Design

• Main sensors will be attached to the Arduino• PerfectFlite altimeter will be used to

determine the altitude of the rocket• Altus Metrum GPS will contain an

accelerometer and GPS system• Information from Arduino, PerfectFlite

altimeter, Altus Metrum GPS will all be transmitted to a ground computer

Payload Design

Payload Safety

• Payload may become too large for the rocket so team members must communicate effectively to ensure this does not occur

• There could be a payload connection failure. Design of payload must prevent this. Plenty of testing is necessary

• Component, subsystem, and system testing• Sensors may fail. A large amount of testing can

prevent this

Payload Safety Continued

• LEDs• Power Switches• Sufficient testing must be done to resist data

logging failure• Redundancy• Components may not handle acceleration.

Recovery System

• Dual Deployment System• Rocket Man R12 Nylon for main parachute• Kevlar Shock Cords

Recovery System Safety

• Ground tests will be conducted to ensure that the parachutes eject properly

• Learn proper parachute folding procedures
