Apogee Rocketry Workshop #378:

How to Design a Multi-Piece Fin

Advanced Construction Video

There are two main reasons that you may have to design a multi-piece fin. The first is that the fin is so large, that it just doesn't fit onto the sheet of wood that you had planned on using. The second reason is so you can orient the fin to acheive the greatest strength.

In this video, we'll walk through these two considerations and give you some tips on how to design the fins so that you maximize the strength and minimize the size of the sheet of wood so you don't waste money.

Apogee Feathered Flyer Kit

Apogee's Feathered Flyer rocket Kit

The tiny little "Feathered Flyer" is a speed machine that jumps skyward with gusto.

Assembly is quick and easy, making it perfect for less experienced builders or those who want a quick build. The kit is inexpensive and uses affordable 13mm diameter motors, so you can launch it over and over again without breaking the bank. However, be careful with how high it goes, as it can quickly disappear from view. You might want to get two or three because it is a nice inexpensive rocketry gift for those that are just starting out. 

BT-60 Nose Cone and Transition

BT-60 Nose cone and Transition

This is a combination product that includes a BT-60 (41.6mm) diameter nose cone and a 1.2" long transition section that fits the BT-60 tube as well as the BT-55 (33mm diameter) tube. You get both pieces for one low price. They come as a single piece, and you just snap them apart when you are ready to assemble your rocket.

The 3-to-1 ogive shaped plastic nose cone is a perfect upgrade for your model rocket. With its sleek and aerodynamic design, this nose cone will improve your rocket's performance and take your launches to new heights. The included transition section smooths the airflow when your rocket changes from one diameter to another, which lowers the drag. But you can also trim off the shoulders to use it as a boattail or a simulated nozzle on the base of the rocket.

Apogee Antares Explorer Kit

Apogee's Antares Explorer rocket Kit

The Antares Explorer model rocket kit is the perfect combination of science fiction style and high-altitude performance. With its sleek and aerodynamic design, this rocket is capable of reaching impressive altitudes, yet still maintains a unique and eye-catching appearance with its bright decals, six fins, and asymmetric layout (where fins are not equally spaced around the rocket). It is sure to be a collector's item, so you might want to get two or three to put in your treasure chest.

Estes Mercury Redstone Kit

Estes Mercury Redstone Kit

The Mercury Redstone model rocket kit is a 1:34-size replica of the iconic rocket that was used in the early days of the American space program. Its significance is that it was the rocket that was used to launch the first and second American astronauts into space. That makes this kit perfect for those who are interested in model rocketry and the history of space exploration.

The finished rocket stands nearly 29 inches tall and features laser-cut, layered balsa fins and a molded plastic model of Grissom’s Liberty Bell 7 and it’s Launch Escape System (LES). The set of detailed water-slide decals even includes the distinctive white “crack” that Gus painted onto the side of his spacecraft to make it resemble the actual Liberty Bell.

More that just a historic replica from the early days of the American space program, this rocket kit from Estes has history in its own right too. This kit is a re-released but enhanced version of the model rocket that the company Centuri produced in the 1960's. Own a piece of history today!

Launch of the Week

Feathered Flyer Launch

This week we're releasing the small Feathered Flyer rocket kit, and thought we'd show you in this week's simulation what you can expect when you launch it. 

It is a zoomy rocket, meaning is accelerates quickly and disappears so fast into the sky. The motor ejects out the back, and it uses what is called "Featherweight" recovery to come back to the earth. It is so light, that it just doesn't come down very fast.

Customer Comments

“I am teacher at Westwood HS in Austin, TX. My engineering club decided to compete in The American Rocketry Challenge (TARC) this year. It is our first year entering the competition. As such, we got off to a slow start. As we saw the submission deadline approaching, we were scrambling to find the parts necessary to build our rockets in time. Apogee was our one stop shop. We got all the parts we needed within a week of ordering. Thank you, Apogee!”

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.
