Peak of Flight Newsletter #459:

Analyzing V-2 Scale Data

Peak-of-Flight Newsletter Cover image

Stanley Sojka is a fanatical purist when it comes to the V-2 rocket. While researching the vehicle to make his own rocket, he discovered a lot of inconsistent dimensional data for the rocket, particularly in discovering the radius used by the designers to create the ogive nose and tail cone.

This article is Stanley's documentation of his journey to track down the most accurate dimensions for the V-2 by scouring the microfilm at the National Air and Space Museum and Naval Research Laboratory. In the end, you'll get a table that you can use if you ever want to make your own scale model of the V-2.

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

N-1 Moon Rocket

Altaira Rocketry's N-1 Moon RocketThe N-1 rocket from the new manufacturer, Altaira Rocketry, is a 1/122 scale replica of the Soviet Union's moon rocket that competed against the American Saturn V. This model stands over 34 inches tall and flies on a cluster of six Estes D12's. This is a very difficult rocket to build, and we only recommend it to modelers with significant scratch-building experience 

Fin Shape Science Experiment Kit

Fin Shape Science Experiment KitThe Fin Shape Science Experiment Kit allows you to find out through experimentation which shape performs the best. The rocket is designed to allow the fins to be quickly switched between flights so that the only variable being tested is the actual shape of the fins.

In this kit, there are four pre-cut fin shapes you can test, and another eleven patterns that you can choose from to make your own hand-cut fins. It also comes with a BT-55 size (33mm diameter) fin alignment jig so you can make sure all the fins are perfectly straight and uniform when attaching them to the rocket. The included display stand allows you to stand the rocket upright when you have it in your science experiment at school.

Fin Alignment Guides

Midge Payload Altitude RocketApogee has those inexpensive laser-cut cardboard fin alignment jigs that position and holds the fins while the glue dries. You get perfect alignment so your rocket flies straight as an arrow. This allows all the fins to be added at the same time in order to speed assembly. Now in five sizes: 13mm (BT-5), 18mm (BT-20), 24mm (BT-50), 33mm (BT-55), and41.6mm (BT-60). The complete set is available here.

Adrel Altimeter

Midge Payload Altitude RocketThis small data-logging altimeter was designed specifically for the modelers that compete in international rocketry competitions (FAI). It easily fits into a 10mm diameter tube and weighs a mere 1.8 grams of battery (battery not included). It records 9 minutes of flight data (at 15 samples per second) that can be analyzed after recovery. It is the official altimeter used in FAI (international) competitions.

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.
