On the front page the PSC Infinity launch photo was credited to John Pace when in fact it was John Brohm s photo. Both John s (sounds like a police report doesn t it?) had submitted launch photos and I mistakenly assigned the wrong credit. The second error occurred on page 17 in the PSC Prez history list. Rod did indeed serve 8 years. But the dates are 1996 (not 1995) to Rod was elected in 1995 but his first term did not begin until January Meridian Passage I recently requested to be added to Francis Graham s daily blog, Meridian Passage. It is comprised of Francis research and opinions on outer space, rocketry, futurology, science fiction and anything else he finds interesting. I have found it to be interesting and entertaining and look forward each day to seeing what the subject for that day will be. Thank you Francis, that takes some real dedication. A great replacement for the Rocket Mail newsletter. And I m sure a lot cheaper. The best of luck to PSC members going to NARAM 53! Go Pittsburgh!

3 The Origins of Estes Model Rocketry The Orange Bullet By John Brohm - NAR #78048 This PSC Shop Talk installment takes a look in the rearview mirror, back to some of the earliest days of our hobby. Our subject is the Orange Bullet, a simple and unimposing model by modern standards, but one that holds an important place in the hobby s history. Its importance rests in its role as one of the first models a hobbyist could build cheaply and fly safely. And along the way, it leveraged an entirely new business for the then fledgling Estes Industries. So before we begin our build project, let s first revisit this story. The story begins with Orville Carlisle s handmade Rock-A-Chute model rocket motors and his refined Mark II model rocket, a product combination which, in part, would ignite the formation of one of the first model rocket companies, Model Missiles Inc (MMI). With the launch of MMI and the further development of Orville s model rocket motor technology, model rocketry turned the corner from uncontrolled amateur experimentation to a consistent and safe mass consumer aerospace hobby. MMI was formed in 1957, and immediately pursued a leading position in the new emerging aerospace hobby of model rocketry. Unfortunately MMI soon found itself struggling with production, sales, and distribution issues. Many of us have heard the well told story of how a young Vern Estes stepped forward and offered to mass produce compatible model rocket motors at a much lower cost for MMI, thereby solving one of MMI s supply chain problems. However, kit production and distribution still plagued MMI, and soon Estes Industries was stockpiling more model rocket engines than MMI could sell. That growing engine inventory prompted Estes to seek its own market entry. The Estes market entry began as a series of mail order ads for model rocket engines, the ads being initially 3 placed in magazines like Popular Science and Popular Mechanics. The success of those ads led in turn to a parts catalog published in mid-1960, which featured a Plans Book (cat# 160-P-1) that depicted several models that could be crafted from the offered model rocket parts. One of the models in the Plans Book was the Orange Bullet, the subject of this PSC Shop Talk installment. The Orange Bullet was an original Estes design, and was an important early step on the road that Estes Industries took to become the dominant model rocket supply company. The Orange Bullet embodied a number of key ideas that Vern Estes was experimenting with in his quest to develop a new method of model rocket recovery. Instead of ejecting a parachute or streamer at apogee, the Orange Bullet would eject the engine, and the consequential dynamic change in the location of the Center of Gravity relative to the model s Center of Pressure would convert the flying model from a stable attitude to an unstable one, bringing about a tumbling effect that would slow the model to a safe speed as it descended. Because the Orange Bullet was a featherweight model, it would impact Earth without damage or ill-effect. Vern Estes felt that this tumbling method of recovery was novel, and filed a patent application to protect the idea on July 5, 1960; the US Patent Office agreed, and granted Patent #3,114,317 to Mr. Estes on December 17, Test flying the Orange Bullet quickly showed that the design was a winner (the Orange Bullet set an NAR altitude record in 1960), and so Estes Industries began producing parts for its mail order business. The body tube stock for the Orange Bullet was hand rolled by Gleda Estes, and this body tube type (listed in the 1960 Parts Catalog as BT-2) was the forerunner of the BT-3/BT-30 that would become the mainstay airframe for most of the early Estes kits. With a rapidly growing mail order parts business, Estes Industries soon saw the demand for model rocket kits; the Orange Bullet design was further refined for kit production and was introduced as Estes Industries first kit, K-1, the Astron Scout, in the 1961 catalog. Let s now dispense with the history and see what it takes to build the Orange Bullet. Figure 1 illustrates the original Orange Bullet plan. Before we begin our build, a few words of caution about the Orange Bullet plan. First, scaling off of the plan can be risky due to variations in scanner interpolation. In general, use the listed dimensions on the plan.

4 Team Pittsburgh #159 Figure 1: The Orange Bullet (figure not to scale) For newsletter publishing purposes, the illustration in Figure 1 has been reduced from full size; you can find the full size plan for the Orange Bullet in the Estes Rocketry Manual, located here: 4

5 Caution is also the watchword when making the body ribs. In the Side View, the body rib is clearly much longer than 2-3/4 (scaling it suggests it should be 3-3/8 ), but the full size body rib pattern shown in the lower right of the plan only measures out at a hair over 2-7/8. One must be careful here indeed! shows the nose cone, and you might just be able to make out one of my body rib extension marks on the nose cone in the photo. So for my reproduction model, I chose to interpret the plan as follows: - Airframe: BT-30, cut to the listed dimension in the plan. - Nose cone: I used a BNC-30D, same as the Astron Scout. It s a very close match to the shape and size shown in the Orange Bullet plan (note: since this article was written, Semroc has since produced a specific Orange Bullet nose, P/N BNC-30DOB) - Fins: I used the template provided in the lower left area of the plan. It seemed to match well with the depiction in the side view. - Body Ribs: I used 1/16 thick x 3/16 wide strip balsa, as recommended, but cut to a length of 3-3/8. As mentioned earlier, this length seemed a good fit with the side view depiction in the plan. Photo 1: Orange Bullet Parts Set Photo 2 also shows the BNC-30D nose cone with the shoulder removed; the Orange Bullet nose cone is permanently attached to the rocket by means of the body ribs, and if left in place, the shoulder will block the ejection gas venting ports, so the shoulder must be removed. I used a razor saw for this operation, being careful to keep the cut square to the base of the nose as I proceeded. If you plan on building an Orange Bullet, the key parts are readily available from Semroc. Photo 1 shows my parts set ready to commence construction. You ll note that I ve just finished filling the body tube seam in that shot. You may also notice that I ve marked each body rib with a center line and with a nose cone edge line; these marks will help align the parts while being glued, ensuring that the ribs are straight and are located in the correct radial positions and with the same length. At this point I ve also marked the body tube with the body rib/fin lines; we want to extend these lines onto the nose cone so that there is a clear alignment mark to match up with the body rib center lines when we glue these on later. Photo 2 Photo 2: Nose Cone, Sans Shoulder The body ribs were then glued in place; I chose to use contact cement for this step, making sure that my alignment lines were in correspondence. Photo 3 shows this step complete. 5

6 Make sure that you let the glue fully cure before moving onto the next step. Since the ribs interface with the nose cone on a compound curve, the rear portion of the rib is going to jut away at an angle tangent to the base of the nose. Later, when the ribs are pulled in to glue them to the body tube, there will be a tension on the rib/nose cone glue joint, so you need to make sure the contact cement has fully cured to preclude the ribs from pulling away from the nose. Team Pittsburgh #159 Photo 3: Body Ribs Attached Once the contact cement had cured, the ribs were then glued to the body tube, as shown in Photo 4; I used Sig-Bond yellow aircraft glue for this step, and I used a few elastic bands wrapped around the assembly to make sure the ribs remained in full contact along the full length of the body tube while the glue was drying. Photo 5: Ready for Finishing Article concludes on next page Photo 4: Airframe Assembly Since I had doped and tissued my fins beforehand, the next step was ready to go; Photo 5 shows the Orange Bullet ready for the finishing stages.

11 Lock Haven Catholic School 8 th Annual Rocketry Program By Scott Alexander NAR# For 8 years now, we have had a 2 week long rocketry based math and science program at Lock Haven Catholic School. This year, like each of the preceding years, I feel that I learned as much as the kids did. The unit begins with Rocket Math and a fair amount of background science on the US Space program and Model Rocketry being taught by the 5 th grade teacher. For the second year in a row, we have a new face in that role. Loretta Jones moved from 3 rd grade to 5 th and jumped right into our rocketry fun. My wife, Michele (former 5 th grade teacher/program instigator/current school principal) mentored her through week 1. During the second week is when I get to join in on the program. Tuesday of week 2 is build day. Friday is our launch day. My friend Gary Oishi joined us once again to assist with range operations and Mrs. Jones s son Benjamin (alumnus) returned to be our honorary LCO. It is always interesting to learn the nature of the class. Each class has presented me with a unique challenge. One year you can t stay ahead of them, the next you might have to drag them through each step with a leash, while another group may be such a mix that you have to make sure that you don t lose the stragglers while others race ahead. This year provided me a unique challenge that I will never forget. I have found through this program that the brightest shining stars sometimes come from the darkest corners. This year was proof, absolute. I always reward the efforts of those who stepped up with some prizes and awards; Highest Flight, Closest to the Pad, Most Artistic, Science and Math Award, or Best Question/Participation. This year, I gave our first ever All Around Best Rocketeer Award to a young gentleman who has a less than stellar background. He stepped up in ways that you would never believe if you knew him and knew his limitations, When I said I was giving this award for the first time, I asked the class who should get it they sang out his name in chorus. He came up to me after class and asked me to write a note to his father, because in his words my dad will never believe this if I tell him myself. I gladly wrote him the note and Michele (as principal) followed up with a phone call home to let them Team Pittsburgh # know just how wonderfully he had performed during the entire rocketry unit. For two weeks, he was a different person. I personally get a great deal of personal enjoyment from model rocketry, but nothing compares to seeing a kid not only enjoying the hobby, but truly benefiting from it as well. Model Rocketry may not change lives, but I have seen it give young people a chance to shine and that has to mean something. **************** THE PSC INFINITY ON SALE now!

12 The Northwest Extreme Rocket Show By Art Nestor Peg and I just returned from a trip out west to visit our daughters and their families. Ever vigilant for opportunities, I found a Tripoli Regional launch scheduled for the same weekend we d be at Becky s home in Oregon about 3 1/2 hours away. Normally when visiting Becky and Kaplan (both geologists, Kaplan an Oregon State Professor and Becky a Hydrologist/GIS Analyst) we do quite a bit of sightseeing so the launch was easily worked into our travels. The NXRS-1 was a three day (Friday, Saturday, Sunday) high power event similar in most ways to other Tripoli launches. We attended the launch on Saturday, leaving at about 4 P.M. when a lull in the launches occurred. It was hot, dry and breezy. While we were there, I didn t see anything extreme. Nonetheless, I saw some cool launches and the people impressed me by their friendliness and innovations. I was glad I went. Rocket magazine was there covering the activities and I ll try to bring the issue that covers this event to a future PSC launch. Let me summarize a few things that caught my attention. Peg among one flyer s collection of scale models I Have Seen the Future and it is Kate. At least for high power rocketry. Kate is the name given to a voice synthesizer that announced real time data over the loudspeaker system received from a GPS unit and transmitter placed in the nose cone of a rocket. The synthesized woman s voice sounded quite human and normal and only once in three flights did I detect the very slightest of pauses while listening. At launch the LCO turned the loudspeaker system over to Kate who then introduced the rocket and instrumentation before giving the LCO the high sign to launch. As we witnessed the flight, Kate continually informed the crowd of altitude, apogee altitude, deployment of the drogue and main chutes, rate of descents in MPH, imminent touchdown at 100 feet and touchdown detected. Then the rocket s location was given relevant to the pad with distance, GPS coordinates and directions. What s Up Hobbies Like most other Tripoli events I have attended, there was an on-site vendor. NXRS s vendor was What s up Hobbies by Jack Garibaldi from California. I have ordered from What s Up before and now had the opportunity of meeting Jack, who is a really nice guy. The vendors I ve previously seen either have a box truck or pull a small trailer. I m sure those vehicles could bring in over ten thousand dollar s worth of stuff, but Jack s merchandise was brought in by tractor and trailer. The Launch Site The launch site was in the middle of eastern Oregon desert populated only by sage brush with visibility in some directions for miles making recovery much easier. The cool thing was that club members owned the launch site and that the surrounding real estate was BLM land, that is land owned by the Bureau of Land Management. Government land. With government prohibitions on construction, Oregon Rocketry should have a great site for many, many years. Can We All Just Get Along? Oregon Rocketry is dual chartered as both an NAR and a Tripoli club. And they get along. NXRS-1 was billed as a Tripoli launch and I attended it as a Tripoli member. The lack of friction between organizations was refreshing and is an example for the Pittsburgh area clubs, Tom Blazanin please take note. Now, how can I get my rockets out there next year? **************** 12

13 to the club this family event includes our monthly sport launch, raffles for donated items and the annual Fun Fly event. If you plan to participate in the I in the Sky fun event, make sure you have your Semroc Iris kit built and ready to fly. For more information on the events visit our website It s hard to believe we re half way through Where did the time go? As in any rocket season the first half is a lot of planning and the second half is all about execution. Based upon the clubs performance in designing and developing our 25 th anniversary patch and commemorative model rocket in collaboration with Semroc; our attendance at Spaced Out Weekend; the turnout for our two regional competition events in April and June; and our 25 th anniversary celebration launch in May; I d have to say the clubs excellent planning produced very successful results. However, there is still much to do and a lot to be done. Our PSC club competitors are busy building models and launch devices for NARAM 53 which will be held outside of Cincinnati, Ohio the week of July 25 th. If you have never attended a national event I encourage you to try to attend, even if only for a day or two. You won t be disappointed. Right now PSC is battling for the Section of the Year Award, a position that has always been too much out of a reach for our club. However, with the help of some new PSC competitors we plan to give the other clubs a run for their money and do all we can to reach this coveted section honor. Another award we will be battling for is the section newsletter of the year. Over the past few years we have finished a close second in the judging. Hopefully this year with the excellent articles by our membership and superb editorial work by Art Nestor we will reach our goal and bring home the North American Rockwell Trophy. If you want to keep track of what s going on at NARAM, Google NARAM Live. There you ll find photos, event results and general news about what s been going on at both the competition and sports ranges. So what s ahead for the club in the coming months? Our work is never done. In August we will hold our annual R&R launch and picnic. For those of you new 13 We will also be raffling off one remaining single digit numbered kit of our 25 th anniversary PSC Infinity. The kit is #5. If you re a collector of unique numbered kits this is the raffle for you. All families are asked to bring a covered dish to share. Also, charcoal grills are available if you would like to grill up a few hot dogs or hamburgers. In October we will be holding a joint launch with Tripoli Pittsburgh, the local high powered rocketry club, at their Dragon s Skull field in Republic, Pa., which is a little past Brownsville. For more information on the club and field visit their website Even though this is a joint launch, we will still be flying the typical 1/2A to G motors that we fly at Camp Lutherlyn in addition to some larger motors. It you are interested in achieving your level 1 or level 2 certification, I recommend you take this opportunity to make your launch since our field is limited to G motors and smaller. Weather permitting, we will hold launches in November and December but should the weather turn nasty we will take this opportunity to hold our annual business meeting and begin the process of planning our launch calendar for I look forward to seeing you at the remaining 2011 club launches.

14 FINDING THERMALS by Mort Binstock First I am most impressed by Rod Schafer s article in issue #156 covering his trip to Serbia to compete in the 18 th World Space Modeling Championships. I was riveted by Rod s tales, impressed by his writing ability. One of the challenges the contestants faced was to locate thermals, rising air currents. Finding and keeping a thermal is often imperative to winning. I can sort of find thermals but I do not consider myself having even near contest thermal finding skills. Fortunately, there is technology to supplement my skills. A while back I wrote about an altimeter manufactured by Winged Shadows (WS). This altimeter, called How High, reads and stores the peak altitude of a model. Back on the ground the altitude is read as a series of pulses. Back to this device shortly. WS now has a new device called a Thermal Scout. The TS is for use in radio controlled planes such as boost gliders. The TS weighs 1/8 ounce, costs $50, and is wired between the radio receiver and the steering rudder. The TS causes the plane to wag notifying the operator of a thermal. Team Pittsburgh #159 Visualize Thermals With the Thermal Scout (Ad) Nothing matches the feeling of piloting your R/C glider higher and higher powered only by invisible lifting currents of warming air thermals. The Thermal Scout greatly aids your ability to find thermals by indicating when your plane is rising in lifting air. When your plane enters lift, the Thermal Scout will swing the plane s rudder from side to side. This creates an overall rocking motion that allows you to see when you ve entered a thermal. The invisible becomes visible! You control the Thermal Scout using an extra channel on your transmitter. Once you have found lift, switch off the unit and circle in the rising air. At any time you can switch the system back on and the waving rudder will verify that you are still in lift. -Installs between your receiver and rudder servo. -Smaller than a postage stamp; only 1/8 ounce. -Uses atmospheric air-pressure sensing to measure lift. (The same technology as our popular How High altimeter.) -For all gliders and motor gliders; works with V-tails and flying wings too. (End of ad) Now back to the How High. There are now new radio controlled transmitters that provide 2 way communications. These high tech transmitters are capable, for example, of reading a model plane s altitude. Transmitters with these features include Spektrum s DX- 8 and HiTech s Aurora. Reading actual altitude is an effective way to search for and evaluate thermals. WS now has upgraded their TS to the Thermal Scout RT. The RT plugs into a separately purchased transmitter manufacturer purchased airborne telemetry module. Altitude is subsequently displayed on the transmitter s screen. Details and contact information are provided in this article s copy of Winged Shadow s advertisements. (Please see the ad copy on the opposite page.) See you at the launch! 14
