Launch Vehicle Specs
University of Central Florida
Selected Payload Options
3.1 The rocket will include a camera that will scan the ground for landing hazards and the data will be transmitted in real time to a ground station and analyzed using custom made on-board software.
Video will be taken using a CMOS 728x488 camera module.
An Arduino Uno microcontroller equipped with an Arduino Video Experimenter ShieldSoftware on the Arduino will analyze the video for hazards.
A 5.8 GHz lightweight video transmitter will be connected to the Arduino.

Duties of the Safety Officer
The duties of the safety officer will be constrained to explicitly to maintaining the integrity of the team’s safety.
The safety officer must remain on site at all times when the handling of hazardous materials of rocket parts is occurring.
The safety officer must be onsite to supervise the team and monitor all actions while onsite.
University of Central Florida
Duties of the Safety Officer
The safety officer must take special note to ensure all safety protocols are being followed properly, along with proper usage of safety equipment.
The safety officer is responsible for documenting all use of hazardous materials and logging all time spent inside the lab.
The safety officer should have a thorough understanding of all materials being used, what regulations and protocols to follow, as well as proper equipment to be worn when handling said materials.

Possible Environmental Concerns
WindDust Salt Moisture Threat to the electrical componentsSalt is an especially abundant risk Salt will be corrosive to the payload and circuitry if
it infiltrates the payload compartment. The impact of landing is also more severe due to
the hard salt on the ground which could damage the vehicle.

Educational Engagement
Educational presentation at Jackson Middle School. Following the presentation students will participate in a
question and answer session regarding STEM fields.Additionally, the team will show the students data from
previous launches and projects that members of Project Advance have participated in.
Build and launch paper rockets and the physics behind it all.ACE day on March 17, 2014, 750 fifth grade students will visit
the University of Central Florida. The team will talk about engineering, show photos and videos
of previous launches and projects, and do STEM related activity.
Both of these events have been proposed and the team is awaiting confirmation to begin preparation for the events.

Launch ProceduresTest launches and launch day procedures
On launch day all materials will be transported safely in the designated crate
The safety officer will supervise all handling of hazardous materials when team members are present.
Any high powered motor will be loaded by the certified personnel present on site and will be checked by the range safety officer.
Black power charges used for ejection will be loaded onsite at the launch site under the supervision of the safety officer, prior to launch.
Procedures pre-launch will be, arming the altimeter, and arming the ejection charges through the respective safety switches. Then one can verify system status by listening for a sound from the altimeter.
All launch day procedures will have final authority given by the range safety officer.
University of Central Florida
Launch Procedures
To be reviewed On the day of launch the rocket’s ejection
charges should be double checked by the certified personnel and the range safety office.
Proper loading of the engine should be double checked by the range safety officer and certified personnel.
The final status of the rocket will be signed off and documented before it is launched off the pad.
