Overview

Model rocketry was developed during the "space race" era.  Due to increased publicity in aerospace companies such as Space X, Virgin Galactic and NASA, there is an increased interest in hobbies related to aerospace.  Building and flying model rockets is a logical extension.  Students who have flown model rockets will have an increased understanding of the design requirements and forces for powered flight which will provide concrete examples when these topics are covered in their STEAM classes.

JSerra's model rocket contest is a unique competition that will be judged based on the criteria described in these tabs.

JSerra will supply each school with two rocket packages.  Each package will consist of all construction materials necessary to build and launch a model rocket.  Engines and recovery wadding will be supplied by JSerra on launch day. Prior to launch day, each team’s rocket will undergo an aerodynamic stability test to determine its flight worthiness. Contest teams will use their own ingenuity to design and paint their rocket. 

Prizes

The winner of the competition will be based on a combination of the rocket's performance and team's performance predictions of their rocket's behavior.  The team's score is based on the following:

  1. Targeted time in the air (75% of score): Judges will provide a targeted flight time measured from launch to touchdown. Points will be deducted based on deviation from this flight time goal, with a baseline minimum below which teams will be disqualified.
  2. Space-X Return (25% of score): Rockets will be scored based on how close they return to the launch pad. Landing closer to the launch site will improve your score.

Judges' decisions relating to safety, launch, tiebreakers, and scoring are final.

1st Place Prize - $20,000 Scholarship

Each team member will receive $5,000 off tuition per year for all 4 years of high school at JSerra along with automatic acceptance to the Engineering Magnet Program.

2nd Place Price - $10,000 Scholarship

Each team member will receive $2,500 off tuition per year for all 4 years of high school at JSerra along with automatic acceptance to the Engineering Magnet Program.

3rd Place Prize - $5,000 Scholarship

Each team member will receive $1,250 off tuition per year for all 4 years of high school at JSerra along with automatic acceptance to the Engineering Magnet Program.

Trophy - Best Design

The judges will award one rocket for best design and appearance. Creativity is highly encouraged! 

Eligibility

In order to qualify for the JSerra STEAM Championship, you must meet these requirements:

  1. Each team must consist of students in 7th or 8th grade currently enrolled at one of these schools: Mission Basilica, St. Edward the Confessor, St. Catherine of Siena, Our Lady of Fatima, St. Serra, St. Mary's, St. John’s Episcopal, and Our Lady Queen of Angels.
  2. Each contestant must complete the JSerra Media Release.

JSerra Catholic High School may disqualify prior to or during competition any competitor who is not in compliance with any of its eligibility requirements; and it may require any competitor who is found to have not been in compliance with any of the eligibility requirements to forfeit the prizes accorded to the competitor as a result of participation in the competition.

Contest Rules

  1. All rockets must be submitted to the judges (Dr. Kilduff and Dr. Maffia) prior to the start of the competition at check-in. Rockets will undergo a stability test by JSerra. Only approved rockets may be launched.
  2. Rocket set up and launch will be handled by JSerra. Student teams under the supervision of JSerra will be permitted to launch their rocket. Only team members are allowed near the rocket launch pads. Teams will be escorted to and from the launch area. Spectators will not be allowed near the launch area.
  3. Weather conditions will determine launch parameters. Parameters include launch direction and parachute area. Rockets will be equipped with 'A' class engines. All rockets start with an unaltered 12" parachute. You are allowed to alter the parachute opening as you see fit. Contestants will be given recovery wadding. Students will load the wadding and the parachute. Prior to engine fitting and firing.
  4. The winning rocket must be able to withstand multiple launches. Only minor repairs can be made to a previously launched rocket. Repairs include: parachute tears; shock cord re-attachment and fin re-gluing. Other repairs are at the judges' discretion. Rockets that have been damaged and are not safe to fly will not advance to the next round regardless of their prior score. Judges have final discretion on whether the rocket can sustain another launch.
  5. There will be two rounds of launches to determine the winner. The top four rockets will be determined after the initial round of launches. The second round will determine the ranking of the finalists and the ultimate winner.

Rocket Design Parameters

  1. Rockets will be constructed only from parts supplied by JSerra.
  2. The main body tube of the rocket must be no smaller than 25.0 cm. This does not include the nose cone.
  3. Rockets may have 3 or 4 stabilizer fins.
  4. Rockets with engine, parachute, and recovery wadding must pass a stability test.
  5. Rockets must be minimally rugged that they survive a minimum of 3 launches using an 'A' class rocket engine.  Engine sizes will be determined by prevailing weather conditions.

Students are encouraged to purchase additional rockets for testing purposes. Rocket packages may be purchased at acsupplyco.com.

NAR Safety Code

JSerra will follow the NAR safety code listed below. JSerra officials and judges will make final determinations on rulings, measurements, and awards.  

NAR:  MODEL ROCKET SAFETY CODE
EFFECTIVE AUGUST 2012

  1. Materials. I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.
  2. Motors. I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer.
  3. Ignition System. I will launch my rockets with an electrical launch system and electrical motor igniters. My launch system will have a safety interlock in series with the launch switch, and will use a launch switch that returns to the "off" position when released.
  4. Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher’s safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket.
  5. Launch Safety. I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets. If I am uncertain about the safety or stability of an untested rocket, I will check the stability before flight and will fly it only after warning spectators and clearing them away to a safe distance. When conducting a simultaneous launch of more than ten rockets I will observe a safe distance of 1.5 times the maximum expected altitude of any launched rocket.
  6. Launcher. I will launch my rocket from a launch rod, tower, or rail that is pointed to within 30 degrees of the vertical to ensure that the rocket flies nearly straight up, and I will use a blast deflector to prevent the motor’s exhaust from hitting the ground. To prevent accidental eye injury, I will place launchers so that the end of the launch rod is above eye level or will cap the end of the rod when it is not in use.
  7. Size. My model rocket will not weigh more than 1,500 grams (53 ounces) at liftoff and will not contain more than 125 grams (4.4 ounces) of propellant or 320 N-sec (71.9 pound-seconds) of total impulse.
  8. Flight Safety. I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket.
  9. Launch Site. I will launch my rocket outdoors, in an open area at least as large as shown in the accompanying table, and in safe weather conditions with wind speeds no greater than 20 miles per hour. I will ensure that there is no dry grass close to the launch pad, and that the launch site does not present risk of grass fires.
  10. Recovery System. I will use a recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery system wadding in my rocket.
  11. Recovery Safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.
