Morgan City High School will be having there Senior Project Showcase Tuesday, December 9, 2014 from 9:00 AM to 12:00 PM. Drop by to see Callie Breauxs awesome High Power Rocket. This rocket will be using a dual deployment recovery system. This is an advanced recovery system which utilizes electronics in recovery and data collection. Callie will be using redundant avionic computers to provide a higher level of safety and assurance recovery will go as planned. The primary purpose of a rocket altimeter is to control the deployment of parachutes for recovery. Thus, they will set-off ejection charges needed to separate the rocket into sections to allow parachute deployment at specific altitudes. The parachutes will guide the rocket to a safe landing. A secondary purpose of altimeters is to collect data about a rockets altitude, velocity, acceleration rate, g-force and pressure changes. Altimeters can also provide location data, real time data streaming and even photo/video recording transmission in real time. Computers and electronics can fail, thus redundant computers are used. This requires at least two complete and separate computer systems which both perform the same function at the same time, thus backing each other up. One of the altimeters will be a Perfect Flight Stratologger. This will serve as the secondary backup computer. It performs the same recovery functions as the primary computer. Programmed delays are set in the secondary computer so it fires its own ejection charges slightly after the main computer. This ensures that parachutes are deployed in the event the main computer fails. NASA also uses redundancy in all avionics on rockets. Callie and her team will actually program the computers using a laptop computer. The primary avionic computer will be a TeleMetrum unit with dual deployment and integrated GPS/Telemetry module. This sophisticated altimeter offers additional features. Data collected by the altimeter will be streamed live to a computer at launch control via Ham Radio communication gear. The launch team will actually be able to track the rocket at all times using Google Earth. Callies rocket will fly near 10,000 feet on the Level II flight at speeds in excess of MACH 1. Deploying a large parachute at apogee could cause the rocket to drift miles from the launch pad. Dual deployment is used to minimize drift, yet allow a safe recovery. We will be sharing a series of videos on dual deployment as educational tools. Keep flying High. Video Link: https://youtube/watch?v=KFbQ17y98hU
