The Rocketry Show

Note: This show was recorded a little while ago. After the session was done, our studio went through some needed updates, which delayed production and recording schedules.In this episode, CG, Gheem and Daniel catch up on the latest (as of this recording) rocket news as well as the status of their projects, and the changes to the show moving forward.CG discusses the new Rocket Flight Computer progress. Here are some screen shots of his new interface software written in Python to connect, program, and download data from his Flight Computers.Check out our website @ https://therocketryshow.com for images from CG's projects. Mentioned in this episode:The Rocketry Forum

This was recorded several months ago, and CG's finally getting it posted.The next episode is about two weeks out, where CG has LOTS to follow up on, and it has a LOT to do with the delay getting this one posted.Enjoy!Mentioned in this episode:The Rocketry Forum

In this episdode, we welcome Steve Taylor from The Experimental Sounding Rocket Association (ESRA)Each year, ESRA accepts over 150 collegiate teams from around the world to compete in the International Rocket Engineering Competition (IREC) for the prestigious title of overall winner! Each team designs, builds, tests and launches rockets with a payload size of up to 2.2 Kg and target altitudes of either 10,000, 30,000, 45,000 even up to 100,000 feet! Rockets are typically 4 to 8 inches in diameter and 8 to 20 ft. long. Multistage rockets and all chemical propulsion types (solid, liquid, and hybrid) are allowed. The goal is to have participants learn their skills by doing (motto: Learn by doing) in a safe educational rich environment.The IREC has been an annual occurrence since 2006. The competition achieved international status in 2011 – when schools from Canada and Brazil joined – and has continued to grow rapidly ever since. More than 1,800 students attended the 2024 competition, representing over 120 schools from 22 countries on 5 different continents. ESRA has operated the Intercollegiate Rocket Engineering Competition (IREC) since 2006. Competitions have been held in the following locations:2006-2016 - Green River, Utah2017-2024 - Spaceport America, New MexicoThis year, it happens at 2025 - Spaceport Midland, Texas.For more info, Visit: https://soundingrocket.orgMentioned in this episode:The Rocketry Forum

We welcome Special Guest Randy Millikin of RailButtons.Com!Randy Millikin of RailButtons.Com joins us to talk about his products, and to talk rockets with us.Some background on Mr. Millikin:I began my hobby of rocketry in the early to mid 70’s and stopped once I discovered girls, cars and got my first bass guitar.I launched my last rocket for many years somewhere around 1976.But then one day around 2003, while surfing the web, I came across Aerotech’s website and discovered this interesting thing called, High Power Rocketry!I remember thinking, WOW...M motors!The biggest I ever flew as a kid was a D, because E’s were not made yet (or if they were, I couldn't afford them!)I thought to myself, “ I need to find out more about this!”.With that information filed away, I finally was able to attend a launch in 3 Oaks Michigan in 2005.I went with my 6 year old son and my father. I was blown away and haven't looked back since.I ordered a few Estes kits that I built with my son and flew them at the school yard near our house.That brought back so many great memories that I just had to start building bigger rockets and fly them with bigger motors.About a year and a half later, I got my TRA Level 1 cert in 3 Oaks.The next year, I was able to get my Level 2, again in 3 Oaks, and a few years later, my Level 3 at LDRS28.So why am I doing this?Matt Strum started selling railbuttons in the 90's and had a very successful on-line business for over 10 years.When he decided to stop selling railbuttons, it left the hobby with fewer (and more expensive) options.After exchanging some email, he helped me with information about how he was able to provide the hobby with such and inexpensive choice for railbuttons.It is my goal to keep supplying inexpensive railbuttons for our hobby and keep Matt's vision moving forward.He was able to sell thousands and I hope to be able to do the same for many years to come.Mentioned in this episode:The Rocketry Forum

Steve Taylor, President of ESRA the Experimental Sounding Rocket Association (ESRA) joins us to talk all things Spaceport America Cup. The IREC event has been going on for over 20 years now, and there is a lot to learn about it!

A bit delayed, but here we are! In this episode, we do a quick review of NARCON 2024, and we give a look behind the curtain to tell you what has been going on...

On this episode, our guest is Vance Martin, an amateur radio operator who goes under the callsign N3VEM. Martin became involved in rocketry as a kid in the typical way; seeing model rockets at the local hobby shop, and discovering the hobby with a friend. As he moved into middle and high school, he discovered mid and high power rocketry through online rocketry communities. While in college he built a PML 1/4 Scale Patriot rocket to use for his Level One, but was unable to find a nearby club to certify, so his L1 rocket sat collecting dust over the years. After college, Vance discovered ham radio, and earned his amateur radio callsign N3VEM, and built a portable station in his vehicle so that he could play radio while being out and on the road for work. As seems to be a pre-requisite for Ham Radio, Vance also became a software and hardware 'tinkerer', so for him, building radio-related projects turned out to be a lot of fun, and is still what he calls his 'primary hobby.' Vance became a Born-Again-Rocketeer about a year ago, when his two older kids found the Patriot rocket stashed in the corner of the family storage room. They asked 'What is this!?!' "...and just like that" says Vance " we started building up a fleet of little Estes kits." Vance decided that it would be fun to combine the two hobbies, and start tinkering with radio and electronic payloads for their rockets. "I knew that 'off the shelf' stuff was available, but being a tinkerer, I wanted to build my own." he recalls. He continues. "I wanted to target mid-power sized rockets with my projects, since I still live in the same town, and still don't have easy access to a club with a high-power launch site." Vance enjoys his hobbies, and is having fun, saying "I'm still very much a rocketry noob, but I'm having a blast dabbling around with building the rockets, and hacking around at hardware and software for the rockets' payloads." Vance's website is : https://n3vem.com/blog/RadioRocketV2/

Are you really 'GO' to use your full FAA waiver? Greg Young shares his experiences with this topic, and what he learned is an eye opening education for all rocketeers! About our guest...Greg shares his background in rocketry... My rocketry experience started in 1961, at the ripe old age of 10years, when I ordered, built and flew rockets from Estes Industries. Try as I may, I was not successful at getting local hobby shops to carry rocketry supplies at that time, as the owners felt they were dangerous fireworks. My flying continued until taking a hiatus during my college, and then post graduate years. When my oldest daughter expressed an interest in rockets (while in 3rd grade) my flying resumed. I joined NAR, and TRA at that time and formed a local rocketry club, the Southtown's Amateur Rocket Society (STARS). When my youngest daughter left middle school for high school, I wound up taking another hiatus, and the club disbanded. My flying hiatus ended when my grandchildren expressed interest in rocketry. I rejoined NAR and TRA, and decided to go through the official high power certification program (something not required back in the 1980's when I flew) and am currently a level 3 flier. I have been involved in 2 NY rocketry groups, one in Geneseo, the other in Penn Yan, and have served from 2016 through the end of 2022 as a member of board of directors, the VP, the waiver holder, the RSO and also served the Prefect of the former for part of that time. I have served on the planning committees for LDRS 34, NSL 2018, and NARAM 62, and during those launches was involved on the field running the range safety operations. Currently I have been involved with local youth (high school and college age primarily), and officially have mentored several school ARC teams which have gone to nationals, and most recently a high school team who was chosen to participate in the 2023 NASA student launch initiative and went on to the nationals in Huntsville. I am hoping to get time to be able to fly more, and mentor more student groups going forward. They are, after all, our future...

The Rocketry Show team talk NSL West 2023 with Ed Lacroix and Matt Abbey.

Jeff Kodysz was a very talented rocketeer. His talents stretched from 3D printing, Lazer Etching, and he had a knack with making logos. He created the current logo for The Rocketry Show that you look at everytime you visit our website or listen to one of our episodes. Jeff passed away a few weeks ago after a short battle with illnesses. He will be missed by his friends, family, and us. We are all glad to have known him.

CG stops by to give a quick update on technical changes some of you may have noticed, and what that means.

Items in this news podcast: SMT Designs releases all of their rocketry designs to public domain Steve Thatcher: "With my upcoming LDRS 40 trip and TRA Tech session there on "3D Printed Modular Avionics Bays", I wanted to make an announcement, so here it is..." Steve Thatcher says “I am in the process of releasing all of my rocketry designs to the public domain under Creative Commons Attribution-ShareAlike 4.0 International” You can read the licensing in detail at https://creativecommons.org/licenses/by-sa/4.0/ You can find the designs on http://www.tinkercad.com/ by simply doing a "People" search for "SteveThatcher". Once you find the profile, click it to view the parts. Steve has also tagged the parts with “SMTDESIGNS”, “AVBAY”, and “ROCKETRY”, but you will get more "hits" that way of other non-related parts. My intent in doing this is to propagate the footprint standard I created for devices and batteries over the last years, so the rocketry community could benefit. Thatcher says “I would also like to see my designs come to a greater use by making them available for no cost to those that have the required equipment.” Steve asks that the footprints for carriers and platforms remain unchanged. Thatcher says”I recognize the need to change things when necessary, but changing footprints negates the universal benefit they provide. Take the time to look at my entire library of parts to get a system view of why things were done.” Steve will be available to answer questions through SMT Designs, and the SMT Designs facebook page. _______________________________ Tripoli News During the LDRS 40 Member's Banquet it was announced that that the Tripoli Wisconsin Association, Tripoli Green Bay, and Tripoli Chicago will be hosting LDRS 41 at the Richard Bong Recreation Area located in Kenosha County, Wisconsin. The event is planned to take place July 6, 7, 8 and 9, 2023. More details and information will be coming soon. _______________________________ New Unified TRA Safety Code https://www.tripoli.org/content.aspx?page_id=22&club_id=795696&module_id=520420 Tripoli Rocketry Association unveiled its new “unified” safety code on May1 of this year. President Bob Brown notes that: Under this safety code, there are no longer Commercial launches or Research launches, just Tripoli launches. There are some changes to the current safety code, such as a common safe distance table, a safety code for both model rockets as well as radio-controlled boosted gliders as well as other changes. Tripoli asks all members to please take the time to read the document in its entirety. Mr. Brown notes that “While your first reaction will probably be there seem to be a lot more rules under this new document, in fact, almost nothing more restrictive has been adopted it’s just compiled into one document now.” TRA notes that they owe a huge thank you to Steve Shannon, “who undertook the daunting task of compiling the information from the original four documents and writing (in plain English, not legalese) a document we can all understand and follow”. ____________________________________ Reminder on NARAM 63 NARAM-63 will be July 16-22, 2022.

chapAppDescWelcome to Episode 114 of The Rocketry Show! In this Episode, we'll be talking about The Hot Nozzle Summer 2021 event! Jenna Kay Foertsch joins us from the Johnson Space Center in Houston, where she works, to talk about it! On July 23rd of this year at the FAR launch site in the desert of California, Tim Dodd, AKA The everyday Astronaut, stomped his foot down on an air powered rocket to kick off an event that has taken the rocketry community by viral storm. Photo: Tim Dodd kicking off the event Credit: Matt of HNS The event known as "Hot Nozzle Summer" started out as a joke on Twitter by a number of young rocketry enthusiasts earlier in the Spring, but very quickly grew into a movement spearheaded by an energetic group resulting in a major launch that took place over the weekend of July 23-26. The goals of this group are stated on their website… "Hot Nozzle Summer is a movement within the amateur rocket community that seeks to break down the barriers that exist within the hobby and make it more accessible to new people, regardless of skill or training in rocketry or engineering. This movement celebrates all aspects of rocketry whether its getting a Level 1 high powered certification through NAR or Tripoli, or just shooting model rockets in the backyard with your kids this summer. You do not have to come to the live event to participate in the movement." Primarily a social media phenomenon, the group’s dedicated leaders pulled off an event that saw many rockets fly many of which were from people new to the hobby, or flying to achieve a higher certification level. Jenna Kay, one of the main organizers of the event joins The Rocketry Show to discuss how the event came to be, what challenges were overcome to pull it off, and what the future might hold for what has essentially become a movement to bring people into the hobby that has not been seen before.

Welcome to Season 7, Episode 113! In this episode: Jesse joins us with his interviews & wrap-up reporting of NSL 2021 and LDRS. He managed to get some interviews from NSL as well!

In this episode, the University of Akron Akronauts high power rocket team traveled to theFriends of Amateur Rocketry (FAR) site for a two staged High Power rocket launch attempt. Unfortunately, they had issues with their second stage, and the flight did not go as planned. They share with us what they learned as of when we recorded this episode. The Rocketry show team rip into the virtual mailbag to review your emails. One of the items discussed during our mailbag segment is the website called the “Rocketry Calculator”. You can find it at https://rocketrycalculator.com/rocketry-calculator We also remind our audience about the Rocketry Show tee-shirts! You can find them here: https://shirts.therocketryshow.com

The Rocketry Show gang try a slightly new format for the workshop shows. We are now inviting fellow rocketeers to the workshop to teach us some of their tips and tricks, and to just talk rockets. Our first guest is Andrew Kleinhenz, friend to both CG and Gheem, Andrew taught us many of the tricks we have built our rocketry tricks around. He with us, answers these questions sent to us from listeners of the show! Shear Pin Questions: How do you figure out how many pins you need? Any issues with the LOC-high power type cardboard tubing and small size 2-56 or 4-40 plastic screws for shear pins? Do you use any reinforcement on the cardboard airframe and components? What size do you recommend? Mid Power, to High Power Cardboard and Fiber Glass recommendations for shear pins Where to place them? Any math equations or an online calculator? Do you test those with ejection charges first? Marco Polo Tracker What actually is that type of tracker? Approximate cost? Where do you buy it? Difficulty of use? What is the range of the unit? (How far away can your rocket be from you and still get data)? Advantages of this and disadvantages vs others on the market Gheem and Andrew on igniters. We had some folks today launching some upgraded BT-55 Goblins today… they used those igniters that came with the package… What would the Rocketry show gang have used?

The entire Rocketry Show team gather for Episode 100 to look back on some of their fond memories, and talk about their projects, and more!
