  Ejection charge pressure?
Posted by: rmulvey - 05-02-2016, 12:13 PM - Forum: Your Projects - Replies (4)

Hi All:

   Finally getting a few minutes to get back to rocketry and building my LOC Bruiser.

   I'm going to try it as a single-deploy with a cable cutter. I'm in the midst of spec'ing out the ejection charge, and since it will be a 7.51x33" compartment, it will take a fair amount. The calculators I'm seeing online for smaller diameter rockets generally suggest around 15PSI.

   However, there's also some commentary about how large diameter rockets don't need that much pressure due to the much larger surface area, with suggestions ranging from 5PSI upwards.

   I'll obviously be ground testing, but since the 5-15PSI range for the amount of body tube to be pressurized includes the possibility of doubling the charge from 6 to nearly 12 grams of BP, I'm curious about what other people have used for charge sizes in large diameter rockets.

  NYPOWER T-30 days!
Posted by: mbclune - 04-29-2016, 09:40 AM - Forum: NYPOWER - Replies (15)

The new MARS BoD and NYPOWER Committee Intends to make NYPOWER 20 a Celebration of 20yrs of this great event. An event launch is a lot of work but that work can and should be a lot of fun! We will begin setup on Friday morning at 9AM, for those who help we will be bringing lunch and beverages (Subway). We encourage everyone to please take a range duty spot to help lighten the load for everyone. 

The NYPOWER Committee has been very busy! A few things to fill people in on. 

Saturday is going to be epic, 

  • We are going to leave the High Power Waiver open for as long as the FAA will allow, in our previous experience that will most likely be DUSK.
  • Starting at 5PM Rochester's favorite BBQ "the 3 Legged Pig" will be serving a Chicken or BBQ rib dinner for a very reasonable price.
  • At 6PM we will be conducting an auction of many Classic Estes, Centuri kits and a Bunch of classic MOTORS!
  • When the Sun goes down we will begin a NIGHT LAUNCH!

All weekend we will be holding 2 actual HIGH Power competitions Mach Madness and Mile High

Details on the website http://nypower.org

Big Grin NYPOWER 20 BFR's and other good things
Posted by: jgoggins - 04-01-2016, 09:18 AM - Forum: NYPOWER - Replies (1)

Hey everyone out there in rocket land.   Tis I, The Shredder. Smile

If you have been thinking I would like to go to NSL but for some reason you can't make it, the second best event in the North East is NYPOWER!
Have any of you taken a look at the BFR's that are in the FEATURED FLIGHTS page at http://nypower.org/ ?  Well, It's one of the biggest rocket lineups
for our NYPOWER event that I have ever encountered.  Now is the time to pass on our web site address to any and all that
love rockets.  Not to mention, order your 20th Anniversary commemorative shirts.  Don't forget to register. Big Grin

This years NYPOWER is not only the 20th Anniversary of the event, but it will have special competition events, auctions, 50/50 cash splits, night launch, and
drawings just to name a few.  Vendors galore for all the rocket supplies you need or just drool over.

So please, once again, let everyone know that this is the one event that you don't want to miss.  Low to no crops, grass launch area,
and very friendly atmosphere in which to bring children to fly or watch.  Either will be fun and exciting.
Oh and food!  Did I mention food?  BBQ, burgers and other such delights await you on the field.

See you there!
The Shredder

  Our final meeting pre-launch season is coming up!
Posted by: gyoung - 03-31-2016, 08:16 AM - Forum: Announcements - Replies (1)

Just a reminder that our last club meeting before launch season commences will be held next Thursday April 7th starting at 7pm at RIT.
The last meeting where JD and David demonstrated our new state of the art, fail safe, and completely water proof (as shown by it working while fully submersed in water!) launch system was exciting to say the least.
At this meeting we will be reviewing information and final preparations on our several outreach activities, NYPOWER, etc.
See you then!

We may have some LED sticks available for sale.

  Kit Attenuator Build
Posted by: nkinsey - 02-12-2016, 03:48 PM - Forum: Your Projects - Replies (3)

Saw someone at an URRG launch with one of these kits, so I bought a couple to try out.  They're available here- http://kc9on.com/store/kits/fox-hunt-offset-attenuator/

Circuit board included, through hole soldering, nothing too terribly hard to get to work, as long as you've had a decent amount of simple soldering experience.  Drilling the holes in the case is probably more challenging depending on equipment.

Followed the directions and got it together, and like, OMG... it works!  There's a trimmer on the board that will allow for attenuation tuning beyond what the knob does, and I think I need to play with that.  Like the arrow antennas attenuator it's very sensitive.  Right now it's freezing cold and windy so we'll have to wait for warmer weather to continue experimenting. 

Arrow's device is $59 plus shipping.  This was $8, plus shipping, buying a box, a pair of co-ax connectors, and a whole bunch of assembly time.  Not sure which is the better deal!  I'll report back later when I get a chance to tune it.  As is, at full attenuation, it does kill the signal completely at about 20ft outdoors.

I don't have assembly pics, didn't have the camera when I was soldering.
