[Not displaying correctly? View web version.] | Peak-of-Flight Newsletter #618: | Previously, we had an article by John K. Bennett that described how to estimate the fin flutter velocity for trapezoidal and elliptical fin shapes. This follow-on two-part article by Professor Bennett describes the process for custom shaped fins, which are not simple trapazoids or ellipses. | Read the rest of this week's article, either on a downloadable PDF for printing out, or on our website (great for viewing on your phone)!

Check out the latest products to hit Apogee's shelves! 3" Nose Cone Ebay Kit | This new 3" nose cone ebay kit allows you to mount electronic payloads within nose cones. This is great for allowing GPS trackers, altimeters, and electronic deployment to be added to short rockets or already completed rockets without having to cut the body tube. If your rocket is space limited, you can use the internal volume inside the nose cone for your electronics. Note: This kit is designed to fit nose cones for 3-inch diameter thin-wall tubes. It will not fit in nose cones that are for heavy-wall tubes. |
Carbon Fiber Sheet for Fins | We just received in a new batch of carbon fiber sheets that are perfect for small rockets. I personally use this on competition rockets where low weight, smoothness, and stiffness are very important. It is only 0.012 inches (0.3mm) thick. We've been out of stock on it for several years, but we recently found a new supplier. The best part is that we got it at the old cost, so we are able to keep the price the same as before. If you've never tried carbon fiber fins before, prepare to be amazed. |
Blue Raven Altimeter | The Blue Raven altimeter from Featherweight Electronics should be considered a flight computer more than just the smallest dual-deployment altimeter (imagine that it fits into a 24mm diameter tube). Use it for just about any rocketry project where you need either to record flight data, or control various events during the flight. It has 4 pyro channels that can each be configured based on your desires, such as speed, altitude, acceleration, or rocket orientation. Use it for staging, clustering, parachute deployment, and separation of rocket parts. Plus it records flight data from six sensors at a rate of 500 samples per second. Did we also mention that it talks to your Android or iOS device via BlueTooth to make setting it up and downloading flight data easy? You want this if you're planning on doing anything advanced in rocketry. |
3" Catalyst Rocket | The new Apogee Catalyst is based around our 3-inch diameter nose cone, and it stands about 36 inches tall. With a 29mm diameter motor, you can literally use one hundred different rocket motors to put it skyward. Go low and slow, or zoom and climb to conquer space and time! It is a simple build that you'll enjoy building, and comes with through-the-wall fins, a premium nylon parachute and heat shield protector. Let the Catalyst rocket be the force that propels you towards a 2024 future filled with excitement, achievement, and boundless potential. |

| Customer Testimonials: “Many thanks to Apogee for their great selection of products and fantastic service. After many years away from the hobby I’m a recommitted BAR. Growing up in the space age in the late 60’s and early 70’s I was hooked on model rockets when I saw my first flight. After many years (decades!) I thought rocketry was a great way to help my grandsons learn about STEM topics and building projects with their own hands. Apogee has helped make this a possibility. I’ve found all of the kits, parts and accessories I need to introduce them to a great hobby and to re-live the rockets from my youth. Dare I say Tim is the Vern Estes for a new generation. Keep up the great work!” -- Douglas Yoder | |

I'm now actively seeking writers for articles to appear in this newsletter. And I want unique and cutting-edge articles because that is what you want to read, right? I realize this, so to get articles from outside writers that have the same level of quality, I'm going to have to pay a lot of cash to make it worth it for them. So I've come up with a compensation package where I'll pay up to $350 for good how-to articles. Are you a writer, and does that interest you? That is a lot of cash! Far more than you'll get by writing for other magazines. And with over 23,000 worldwide subscribers, if you write for the Peak-of-Flight Newsletter, you'll gain a lot of notoriety. Writing for the Peak-of-Flight Newsletter is a great way to show off your rocketry projects and your technical expertise, at the same time as helping out other rocketeers. Imagine how great you'll feel knowing that you made a difference to the hobby. If you're interested in writing, see the guidelines on our site. | |
