RockSim Virtual Rocket Contest
CONTEST - IS OVER!
Contests:   All   Previous   Next

In March of 2003, Essence's Model Rocketry Reviews (EMRR) introduced the idea of "Virtual" Rocket Contests. After 7 contests, we are impressed with the participation and fun they have been. To celebrate and have some more fun, we are introducing this "Virtual" Rocket Contest: "Virtual" Reunion.

The contest is geared for any one, but we are hoping to get all 46 individuals that have participated in "Virtual" Rocket Contests previously. Please help me do that and while you're at it, invite someone new. Here are all the previous participants:

53.3% Responded - 42.2% Entered + 7 Newbies!

STANDING
#1 - Chan Stevens Zeus Buster! image 0 0 2.7 1
Drag Race = F72-10 (-30) Pic
Is Chan's conquest over? Is he now unbeatable (especially without EMRR competing!) His strategy of having the first entry allowed him to squeak past Austerberry, who won overall without bonus points applied.
#24 - Dave Austerberry Unknown Variable image 0 0 0 2
Drag Race = F72-10 (-21.4) Pic
Dave is back with a sleek design and really proved to be the point winner in the drag race. Bob Cox would have beat him outright though.
#2 - Steve Naquin Reunited Ripper image 0 0 2.6 3
Drag Race = G55-15 (-2) Pic
Solid performance for a rocket that reminds me of a worm. Sorry, Steve, but nice finish.
#20 - Douglas Gardei Cosmo Probe image 0 0 0.8 4
Drag Race = F39-9 (-5) Pic
Love the detail and look at where this F39 placed against the F72 and G55's!
#25 - Andy Peart Illegal Penguin image 0 1.6 0 5
Drag Race = G55-15 (-3) Pic
Highest scoring Newbie. That is something to be proud of. Now come compete when luck isn't a driving, err, flying factor!
#22 - Jeff Lane Biopsy Maximus image 0 0.5 0 6
Drag Race = F72-15 (-30) Pic
Jeff blows away the field in events #1 and #2. But suffered with mediocre performance in events #3 and #4.
#10 - Brandon Harrison VRCD-8 image 2.0 1.6 1.8 7
Drag Race = F72-10 (-26.5) Pic
Another Newbie with a great showing and the first entry to submit build and flight pictures. Way to go!
#17 - Chris Coffin GoldmemberX v2.0 image 0 0.5 1.1 8
Drag Race = F72-10 (-13.562) Pic
Welcome back Chris. Nice job in the altitude event.
#19 - Jim Myers Sappy image 0 0 0.9 9
Drag Race = F72-10 (0) Pic
I don't understand "Sappy"... I would have named it Techni-color! Made it to the top 10, regardless.
#11 - Geoffrey Kerbel Global Flyer image 2.0 1.6 1.7 10
Drag Race = F39-9 (-15) Pic
Another "Virtual" to "Real" rocket. Nice futuristic looks too.
#7 - Phil Handley Core Sampler image 0 1.6 2.1 11
Drag Race = G37-6 (-10) Pic
Welcome, Phil. I see higher placements in your future.
#9 - Layne Pemberton VR-3 Tequila Sunrise image 0 1.6 1.9 12
Drag Race = F72-10 (3.126) Pic
Layne you are now officially EMRR'ized. You will not be able to stop.
#6 - Bill Cooke Go 4th image 1.0 0.5 2.2 13

Bill Cooke built it and was waiting for good weather to fly it. Nice profile.
#15 - Bob Cox Retribution of Zeus image 0 0 1.3 14
Drag Race = F72-None (-1) Pic
Bob? Bob? Where has the "real" Bob Cox gone too?
#12 - Claude Paquin Gold Rush image 0 0 1.6 15
Drag Race = E30-7 (-30) Pic
Claude's rocket is tipped with a 24K Gold Nose Cone... really.
#26 - Andrew Dobos Gaussius 1 image 0 1.6 0 16
Drag Race = E9-6 (0) Pic
Andrew, you did well for your first contest. What does Gaussius mean?
#18 - Mark Thompson Antares Hawk image 0 1.6 1.0 17
Drag Race = F21-8 (-7) Pic
My eyes bugged out when I saw Mark's entry. Very neat and stylish for a Newbie!
#21 - Jeff Henry Hank image 0 0.5 0 18
Drag Race = F39-9 (-28) Pic
Jeff was late in seeing my calls for a reunion, but dropped everything and threw together an entry for the sake of it. Thanks.
#23 - Clive Davis Porpoise with a Purpose image 0 0 0 19
Drag Race = E30-7 (-30) Pic
Clive, what are we going to do with you?
#13 - Michael Mangieri Steel Raptor image 0 0 1.5 20
Drag Race = D12-7 (0) Pic
One of my personal favorites for looks. Might have over-looked the other motor possibilities for the drag race.
#27 - Peter Stanley Needle Rocket image 0 1.6 0 21
Drag Race = F32-10 (1) Pic
Peter you were last but not last, and first but not first. (This is deep stuff here).

Morgan, we loved your chicken in VC#3, and we love it more now. Thanks for coming back.
#16 - Nathan Schoenkin Rocket In Pocket 2005 image 0 0 1.2 24
Drag Race = F32-12 (-2) Pic
Great looking rocket Nathan. Time to get it out of the pocket and into the air. See you next contest.
#4 - Todd Mullin XF-19 Kestrel image 0 0 2.4 25
Drag Race = G55-10 (-30) PIC
Do you all see how large this rocket is? Todd, if you build it...
#5 - Bruce Levison Twin Boomer image 2.0 0 2.3 26
Drag Race = F72-5 (-30) PCI
The absolute best stretch of the build criteria, hands down! Did a RockSIM calculation impact the performance? News at 11.
#8 - Eric Maglio Night Hawk image 0 0 2.0 27
Drag Race = F72-10 (7) Pic
Eric. I for one was rooting for you. Don't give up with that demo software.

Event #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)

Your rocket flew in RockSIM default conditions with ZERO wind using a C11-None, E6-None, and M900-None. The M900 is the Ratt Works motor with the diameter, length, empty and propellant weight all changed to match an Estes E9.

Well, the first time EMRR ran a "Virtual Contest" some complained about the "luck" factor. With so many unknowns, that plays a part.

These results are a re-run with the sampling rate at 2000 verses 800. This was necessary to get rid of the false unstable flights.

Event #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).

Your rocket flew in RockSIM default conditions with ZERO wind using an Aerotech F101T-None. All rockets were set to 7.0 ounces and the Sustainer CG as designed.

This was interesting to see the range of altitudes based on the designs submitted when weight and motor were standardized.

Event #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).

Your rocket flew in RockSIM default conditions with ZERO wind using an Estes E9-8.

QA

  • 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 Rocksim?
    • RockSim.
  • How are Contest Points scored?
    • Each of the 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 #2 (maximum altitude) and entry #1 gets 800 feet, #2 810 feet, #3 750 feet and #4 950 feet. Then the scores will be 2 points for #3, 3 points for #1, 1 point for #2 and 4 points 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 will be set motors for Events 1, 2, and 3 with set delays. For event 4, you choose the motor.
  • Aren't the RockSim 5 and 6 users going to be upset about not being able to use the RockSim 7 variations? How about using the other software?
    • No, RockSim 8.0 Demo is now available at Apogee
  • How about using the other software?
    • Okay. What do you have? We will need to build up your model in RockSim 8.0 to participate.
  • Drag coefficient: Should we use the default Cd (0.75 for sustainer, 0.78 and 0.80 for boosters), or should we calculate Cd at simulation time?
    • Calculate at Simulation Time. Also, it will be set to "Use the Rocksim Simulation equation in simulations".
  • I didn’t see anything about dual deployment (i.e. drogue chute and main chute). Is that allowed?
    • No, you must use the "Deploy at engine ejection" option
