UFO 2017 Standings

UROC's Fall Contest event  the UROC Fall Open (UFO) 2017 took place on Saturday, October 14th. The event began about 8am in 27 degree temps with clear blue skies and no wind.  So we got our birds in the air a quickly as we could. We were flying under the new National Rocketry Competition (NRC) rules so there were no points but we all still had a lot of fun.  We had some pretty good flights and some nice Scale models.  Al Mecklenburg had a sliding wing Rocket Glider that made 2 excellent flights to earn him first in that event.  By the time it got warm enough to generate thermals the wind also came up.  We finished up about noon.  Looking forward to the NAR launch in November.

UFO-1 2015 Contest Results

The morning started out rather brisk with temps in the 40s but fortunately no wind. In fact the skies remained clear and the air fairly calm for the whole day. At 7:30 in the morning, it was quiet and peaceful as I was setting up my launch gear. After the sun came up, it started warming up nicely. We had our usual group of competitors there with a new addition, William Cooper. In the foreground are Randall and Cathy Redd with Fred Williams setting up. As people started showing up we started getting our Egglofters up to take advantage of the calm air. Bruce Bell won top honors in Eggloft with a 655 meter flight using an Aerotech E20-7 motor. William Cooper was close behind with an excellent flight to 624 meters.

B Boost Glider and B Helicopter were dependent on catching a thermal to turn in a good flight. The time for a non-thermal flight in Helicopter and Boost Glider was around 60 seconds. The models that turned in the best times flew closer to noon when the thermals were more abundant. The Helicopter of choice seemed to be the Gyro Chaser from Apogee. While the Boost Glider of choice was the Condor also from Apogee.

The Scale models were turned in and judged. We definitely have a better crop of scale models this year as modelers are getting better at building them. Bruce Bell flew a well-made D-Region Tomahawk to a second place while Mark Snaufer had a beautiful Delta II. In team division there were 2 extremely excellent models from Pod Bay Doors (Matt Steele) flying a TCMP-2 and Dizzy Dog (Fred Williams and Randall Redd) flying a RAM-B. Both of these models were NARAM quality and were about as close to perfect as I have seen. There was only 20 points separating them after static judging. The RAM-B suffered some damage from a problem with the flight and the TCMP-2 came out on top.

Bruce Bell's Doberman

I have always built short fat rockets because I liked seeing them take off slow. So for Hellfire this year I decided to go in the opposite direction and build long and lean. My project started with a Liberty Launch Systems Competitor 4. This is a 10 foot long all fiberglass kit with G-10 fiberglass fins, coupler and a 5:1 nose cone, and comes equipped with a 24" long 75mm motor mount tube and centering rings. The booster section is only 48" long, which could present some problems with a few motors that I might want to use and not provide enough room for a proper installation of a drogue system. So I also purchased an additional coupler and 24" airframe section. With the additional section added on, the booster is now 72" long, plenty long enough for even the longest 75mm motors.  

I started with the motor mount by gluing the forward CR on to the motor tube about 2" from the end. I drill a ¼" hole in the forward CR and feed the Kevlar shock cord through the hole and tie it around the motor tube. I fill in with generous amounts of epoxy to hold in place. I drilled 2 small holes in the other centering ring (CR) and mounted (temporarily) a pair of small screw eyes.
This way I can slide that CR on and off while gluing the fins in place and gluing the motor mount tube in place. Once the 3 fins are glued in place, I pull the rear CR off and now apply the fillets to the fin roots. Once that is done, I glue the rear CR on, leaving enough MMT tube to glue on the SlimLine motor retainer. I cut about ½" off the base of the nose cone and use this ring to reinforce the tail of the rocket by gluing it in behind the rear CR. This helps with those hard landings out on the Salt Flats. I now apply some nice fillets to the fins on the outside using some thinned JB-Weld.
The Liberty kits do not come with an electronics bay, but they do come with a coupler and end caps. I purchase the hardware including ¼" threaded rods, nuts, nylon locking nuts, washers, wire, terminal strips and a 9v battery holder. The altimeter of choice for me is the PerfectFlite ALT-WD. I start by gluing the end plates together after dry fitting them in the coupler tube. I marked where the threaded rod holes and the U-bolt holes need to go and drill those.
I then cut the 2 threaded rods to about 3" longer than the coupler. I mounted the hardware in the mains side first including the threaded rods and the U-bolts. Note, I used nylon locking nuts to make sure nothing falls off at a time when you most need things to stay together, like just before your chute deploys.
I mounted the drogue side end plate to the threaded rods as shown below. I cut out a piece of 1/8" plywood so that it fits comfortably inside the bay and marked along both sides of the threaded rods with a pencil on the plywood. Then I glued on some heavy ¼" I.D. tubing for the sled to slide on the rods.
I then very securely mounted the 9v battery holder and the altimeter on to the sled, on opposite sides. If there is a crash, the battery would normally be a projectile, so this keeps the battery away from the altimeter.
Now with the electronics mounted, I glued on the charge cups and the terminal strips. I used #20 gauge strip wire, and went ahead and wired everything up, leaving a generous loop of wire inside the bay to allow accessing the bay for battery replacement. I used a on/off switch from Aerocon to turn on the electronics from the outside. I notched the bottom of the mains compartment to accommodate this switch.
I painted the whole thing with a coat of "glass-friendly primer" and a coat of black enamel. I then added a pair of PML rail guides. I plan on flying the Doberman on a Aerotech M-1297 at Hellfire, will weigh 25 pounds and fly to about 8,000 feet.

Big Dog

Bruce Bell's 41 pound Big Dog is over 6' tall and 10" in diameter and is made from pre-fiberglassed tube. For the primary electronics Big Dog utilized a Perfect Flite Alt-WD and a G-Whiz LCX as backup. Recovery was via a drogue 36" parachute at peak altitude and a 12' main chute at 1,000' agl. 

BigDog lifts off under power of an Aerotech M1419 to a successful Level 3 certification flight. The altimeters reported altitudes of 9,120' and 9,132'.

100_0881 The upper part of the 98mm motor mount tube in Big Dog houses a piston tube to eject the main chute. To help strengthen the tube, fiberglass tape was epoxied to the tube. Bruce used a combination of West Systems 105 Resin and 207 Hardener. Note that this combo AT ROOM TEMP (75 degrees) will allow a working time of more than 30 minutes. However, according to Bruce, "as I found out, working in a shed in 98 degree temps, the working time was reduced to about 15 minutes!"

You can do several things to offset this, work early in the morning when it is cooler or, apply a little less hardner (West Systems advises against this as the incorrect mixture will make the epoxy brittle) or go with the 209 Hardner which has a working time of more than an hour.
100_0882 On the upper centering ring is where the parachute connection U-bolts are located. Most kits use one u-bolt, however I went with two so that the drogue chute and main chute would be separated on opposite sides of the motor tube, minimizing the chance of a tangle.
