    2. Max Altitude: your rocket will fly with a "contest mass override", "contest conditions", and a "contest" motor. The placement score will be the Altitude (ft) . - See Results
    3. Slow and Low: your rocket will fly in "contest" conditions with (1) "contest" motor. The placement score will be based on highest Time to Apogee (sec)) and lowest Altitude (ft). - See Results
    4. Drag Race: your rocket will compete in a double-eliminate drag race in "contest conditions", with a "contest" motor. 3 points are up for grab for each flight. 1st) Fastest to clear launch rail (sec), 2nd Longest time to landing (sec), and 3rd Lowest Range (closest to pad in feet) - See Results

* NOTE: All "contest" settings and entries will not be disclosed until all entries are in!

CONTEST #1 -Versatility: your rocket will fly in "contest" conditions with (3) "contest" motors. The conditions and motors will not be disclosed. The placement score for each flight will be the Maximum Altitude (ft) * Rocket Weight (oz)

Details:

  • Contest Conditions: See Here - after all it is Vermont
  • Contest Motor: Attached ENG File
  • Comments: This contest was interesting because the highest actual flier did not become the leader. Once the weight is multiplied to the altitude, super high fliers were reduced because they were so heavy. The "versatility" part is also interesting, since the rocket designs performed differently with the different motor thrust curves, the leader performed about the same across all three motor types. This, in combination with the other contests, might make a good NAR RD project.

Details:

  • Contest Mass Override: Each rocket was set to 2 ounces with the CG set to whatever the original's rocket position
  • Contest Conditions: See Here - after all it is Vermont
  • Contest Motor: Attached ENG File
  • Comments: We believe this contest really shows off "good design" once the weight is normalized for all entries.

CONTEST #4 -Drag Race: your rocket will compete in a double-eliminate drag race in "contest conditions", with a "contest" motor. 3 points are up for grab for each flight. 1st) Fastest to clear launch rail (velocity), 2nd Longest time to landing (sec), and 3rd Lowest Range (closest to pad in feet)

Details:

  • Contest Conditions: See Here - after all it is Vermont
  • Contest Motor: Attached ENG File
  • Winner's Bracket: Your rocket will accumulate the score, from 2-3 points (based on above) for each win in the winner's bracket.
  • Loser's Bracket: Your rocket will score zero (0) points for each loss. Your rocket will score 1 point for each win in the loser's bracket.
  • No Opponent: If there are not enough entries to fill the brackets (once sized to the smallest increment of 8) then a "no opponent" advance will gain 1 point.

QA

  • Do I interpret "There must be at least 2 sets of 3 or 4 fins, different shapes and the bottom of the root edge at a different place" to mean the the two fin sets cannot be placed to make a 6-8 fin rocket? In other words, the trailing edges cannot be at the same location?
    • Not exactly, you could have a 6 or 8 finned rocket just as long as the bottom (rear) of the root edge is not in the same spot. For example, 1 fin set even with the bottom and the second fin set (splitting the first set and a different shape) at 0.5" from the bottom. Or 1 set of fins even with the bottom and another set up by the nose cone. Or... oh, you got it I'm sure.
  • How does this Bonus thing work?
    • The 1% bonus improves your virtual flights by 1%. For example if you fly to 1540 feet, you will be recorded at 1555 feet. Yes, not much, but we suspect some very close competition and it is geared toward a "virtual" rocket contest, but we wanted to award some that actually built the rocket.
  • If we submit a design and it doesn't qualify for some reason, are we allowed to rework the design and resubmit or even submit a new design?
    • Yes, either, both...we will review them and let you know.
  • What is the measure for the one caliber rocket stability requirement Barrowman or Rocsim?
    • Either.
  • How are Contest Points scored?
    • Each of the first 3 events have a "placement score" described. That placement score will then be reversed ranked by the total number of entries. This will give the maximum number of points to the winner in the event. For example, if there are (4) entries and in contest #3 (minimum altitude) and entry #1 gets 800 feet, #2 810 feet, #3 750 feet and #4 950 feet. Then the scores will be 4 points for #3, 3 points for #1, 2 points for #2 and 1 point for #4.
  • You say materials must be those listed in RockSim ... can I build/design any part using those materials?
    • Yes, you may. This does not imply that you have to take the part from the database.
  • In the events that are described, is the Maximum Altitude the maximum possible (excluding the delay of the motor(s) chosen) or actual predicted (including the delay of the motor(s))? I.e., a design could go 1500 feet on a C6-7 but less on a C6-5 because of early ejection.
    • There are set motors for Events 1, 2, and 3 with set delays. Thus far with 9 entries the delays have not impacted the events. For event 4, there is a set motor, then I will choose the delay closest to the predicted delay.
  • How does this Drag Race, Double-Elimination thingy work?
