This newsletter continues to the second part of Dave Flanagan's article on the Vortex Ring Decelerator (VRD). In part one, you discovered the basics geometry of the VRD, and got plans for an assymetrical version of the parachute. In this article, you'll learn about the asymmetric version of the device, and see how to fold them properly for flight. Why you might want to use this style of spinning helicopter-like parachute? A regular parachute might have a drag coefficient of 0.8. By contrast the drag coefficient of the Vortex Ring Decelerator can approach twice that. The opening shock of the VRD is only 2/3 of that of a regular parachute under the same conditions, so it can deployed at higher speeds without snapping in two. The VRD oscillates no more than ±2 degrees during descent, where regular parachutes can oscillate as much as ±30 or even ±40 degrees. That means if you have a delicate payload that you don't want to sway back and forth and whack the ground or the side of a car at a high horizontal speed, then this may be something you'd be interested in. | | 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! | | | The North Coast Rocketry X-Stand holds your rocket in a horizontal position so that you can work on applying those intricate details like small decals or decorative items. It is also great for displaying your completed model in a horizontal orientation. |
| | | Do you like cluster models? The Ultimate is a monster rocket that can use up to seven 29mm diameter motors per flight. That's a lot of thunderous noise and a lot of flame belching out of the rocket at lift-off. But you can actually fly it with any number of rocket motors from 1 to 7, so it doesn't have to be as complex as you'd think. It is perfect for putting on a spectacular show at your next club launch. You'll be the king of clusters with this beast. |
| | | This colorful chute is great for smaller rockets. It has cut lines for 12", 15" and 18" sizes, as well as a spill hole in the middle. Made from High-Density PolyEthylene (HDPE) plastic. Comes with thick cotton string for the shroud lines, and tear-resistant hole reinforcement rings. Because of the three sizes, you can use this chute for most of your small model rocket fleet. You might want to get several so you have extra spares when your friends want to borrow a chute from your range box. |
| | | The Aerotech J520W motor, which fits the 38/1080 case, is a USPS shippable "J" motor. That means you can get your L2 certification without paying a HAZMAT shipping fee! Right there, you've saved yourself a big wad of cash. But it may not be for everyone. Why? This is a very high thrust rocket motor, so be prepared for it by having a well-built model that can withstand very high acceleration. On the plus side, it belches out a big white flame that really enhances the experience of your launch. It is a really cool effect, if that is what you're looking for. |
| | | The Estes Viking is a small rocket that features cardboard fins that can be attached on any of their four edges. With up to five fins per rocket, this allows for 48 different combinations. If you're using this in a classroom, it can make each of your student's rocket look unique and perform differently from each other. This economically priced bulk pack includes 12 rockets. |

I need help with generating the bi-weekly 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. If you're interested in writing, see the guidelines on our site. | |
