Peak of Flight Newsletter #463:

Make a Compact Baffle for Short Rockets

Here at Apogee Componenets, we sell many different baffles for rockets. Michael Moran has come up with a different style baffle that can be used on shorter rockets.

What I like about Michael's article, besides the inginueity of the design, is that the author goes through the process of computing the vent area of all the holes in the baffle to make sure the design will work properly without blowing out the baffle from overpressurization.

He also includes a near step-by-step assembly process for putting the baffle together and installing it in the rocket.

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)!

What is new in rocketry? Here are the latest items to land on Apogee's shelves!

Vaccum Form Transition

This small transition was designed for competition rockets like the Apogee Spek and the Apogee Midge. It joins an 18mm diameter (BT-20 size) tube to a 13mm diameter (BT-5 size) tube. Made from lightweight hi-impact polystyrene plastic, it has a smooth surface that reduces drag and is easy to paint.

New 30 and 36 Inch Parachutes

These are tough rip-stop nylon cloth parachutes with a highly visible printed pattern that adds some color to the rocket's flight. The fabric is soft and everyone says it feels like silk. Because of this, the chutes can be packed tighter to fit smaller diameter tubes.

Octagon shape, the size is measured from flat edge to flat edge.

These are great for mid-power size rockets because the construction is heavy-duty.

“I've been dealing Apogee for about 3 years now and I have always been happy with their prices an their customer service. They ship promptly and keep you notified of your order along the way. I had an electronic part I ordered from Apogee which turned out to be a bad part (NO fault of Apogee) and they replaced the part the following day! They are probably one of the best, if not the best in providing awesome customer service! Apogee has a huge number of items to choose from at very good prices. They have just about any parts, components, motors, casings, or, electronics you need, and provide you with the help you might need in putting it all together. The videos they offer have been a huge help when I needed some guidance. Tim provides some fantastic hints and tips that you probably never thought about using! Thank you Apogee!!!"

I need help with generating the biweekly newsletter articles since it takes a lot of effort to put them together. And I'm willing to pay big bucks for your help.

So ask yourself, are you looking to earn some extra money?

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.
