STOP! March 5 2022 NO GO For Launch
NO GO – March NCR Launch
Mother Nature prevails. The weather forecast for the Briggsdale area has precipitation starting before midnight tonight and going until noon Saturday, turning to snow. Sunday doesn’t look any better. The predicted temps during launch time will be below freezing, albeit only a smidge with winds 17 to 20 mph blowing towards the road and with 100% cloud cover. Call me soft but we’re going to scrub. SCORE in Pueblo plans to fly with warmer temps predicted but stronger winds.
NOGO FOR LAUNCH – Dec 4, 2021
Members and Friends,
There is a scheduled Northern Colorado Rocketry launch event on Sat, 12/4 at the Atlas launch site.
Members and Friends,
Go figure. Opportunities change that quickly…..
National Forests along northern Front Range enter fire restrictions; provide fall safety reminders
Release Date: Nov 30, 2021
FORT COLLINS, Colo. (Nov. 30, 2021) – Due to dry and warm conditions and recent fire starts, the Arapaho and Roosevelt National Forests’ Clear Creek, Boulder and Canyon Lakes ranger districts along with the Pawnee National Grassland are enacting Stage 1 fire restrictions effective at 12:01 a.m. Wednesday, Dec. 1. Stage 1 fire restrictions limit where and what type of fires visitors can have and remain in place until rescinded.
The following is PROHIBITED under Stage 1 Fire Restrictions:
- Igniting, building, maintaining, attending, or using a fire (including fires fueled by charcoal or briquettes) outside of a permanent metal or concrete fire pit or grate that the Forest Service has installed and maintained at its developed recreation sites (campgrounds and picnic areas).
- Smoking, except in an enclosed vehicle or building, a developed recreation site, or while stopped in an area at least three feet in diameter that is barren or cleared of all flammable materials.
- Operating a chainsaw without an effective and properly installed spark arrestor, a fire extinguisher kept with the operator, and a shovel.
- Blasting, welding, or operating a torch with an open flame without being in a cleared area of at least 10 feet in diameter and having a fire extinguisher kept with the operator.
- Using an explosive. This includes but is not limited to fuses, blasting caps, fireworks, rockets, exploding targets, tracers, and incendiary ammunition. (Fireworks are always prohibited on National Forest lands).
Violation of Stage 1 fire restrictions could result in a maximum fine of $5,000 for an individual or $10,000 for an organization, or imprisonment for more than six months, or both. If responsible for causing a wildfire, one could be held accountable for suppression costs of that fire.
Looks like SCORE is still planning to launch at the Hudson Ranch.

2021 MHM Launch
Awesome flying on the Pawnee for Mile High Mayhem this year.
Thanks to George Barnes for all the great photos!
Launch log data coming soon.
2021 Alphabet Contest
Entry Information
$10.00 Entry Fee with $5.00 Re-Entrance Option
Make sure to declare your flight as an “Alphabet Contest” on your flight card prior to launch.
A registration sheet should be available at the LCO desk; contact Brad Morse if the sheet is missing.
Deposit your entry fees with Brad Morse.
Contest Rules
Fly and successfully recover a model rocket, using each motor class in succession: A, B, C, D, E, F, G, H, I, J, K, …
You may use a different rocket for each flight, or the same rocket for multiple flights as you desire. Each flight must be declared prior to launch as a contest launch, and designated on your flight card.
Disqualification
If you have a failure resulting in damage that prevents a second flight without repair, or you are unable to recover the rocket, then your last successful flight will be recorded as your final flight for the contest.
Re-Entrance
Flyers may re-enter for an additional fee. You will re-join the contest at the motor that you were disqualified at. For example, if your E flight failed, you would continue the contest at an E impulse motor.
Contest Duration
June – October
The Alphabet contest is open from Mile High Mayhem (June 4) thru Oktoberfest (October 3). Contest winners and prize money will be awarded at the end of flight activities on October 3 or at the club annual meeting.
Build Constraints
All rockets must be stable and constructed with materials approved by NAR or Tripoli.
Multiple Stages
Multiple stages may be used to accomplish multiple letters of the alphabet in a single flight. You must recover all stages successfully. Limit up to and including 3-stages.
Contestants must progress through the alphabet contest sequentially.
You cannot skip any letters of the alphabet, flights with multiple motors that are not sequential are allowed, but you can only achieve a single letter in the alphabet contest if your staged-motor configuration is not sequential.
Ignition sequence does not have to be alphabetical. You may fly a staged rocket that has a C as the booster, and a B as the sustainer (assuming you have successfully completed your A impulse flight).
Clusters
The total impulse of the cluster can be substituted for the impulse letter in the alphabet. For example, a cluster of 6 (six) E motors @ 40ns each would have a total impulse of 240ns, which is equivalent to an H motor.
| Impulse | Thrust Range (ns) | |
| 1/4 A | 0 to | 0.625 ns |
| 1/2 A | 0.625 to | 1.25 ns |
| A | 1.25 to | 2.5 ns |
| B | 2.5 to | 5 ns |
| C | 5 to | 10 ns |
| D | 10 to | 20 ns |
| E | 20 to | 40 ns |
| F | 40 to | 80 ns |
| G | 80 to | 160 ns |
| H | 160 to | 320 ns |
| I | 320 to | 640 ns |
| J | 640 to | 1,280 ns |
| K | 1,280 to | 2,560 ns |
| L | 2,560 to | 5,120 ns |
| M | 5,120 to | 10,240 ns |

2021 NCR May Days [North Site]
Launch Summary
Happy May Day! Huge THANKS to Jack Matthews for towing both ways and for range set up with the help of Scott Dukes, David Pinter and everyone else that assisted. We were OK to proceed as planned with the scheduled Saturday May 1st and Sunday May 2nd launch event, at the North site, subject to the normal precautions. Basic COVID hygiene protocols were still in effect: If you had a fever or if you felt sick, don’t show up; keep at least 6′ or more between your prep area and the next person.
An orientation briefing for participants was held and included a discussion of safety and emergency procedures, fire conditions and instruction, applicable rules and regulations, and what is expected of participants with respect to the use of NFS lands under our special use permit. Waiver was from 9 AM to 6 PM but we were pretty much done by 5 when weather started to threaten.
