Richard Nakka's Experimental Rocketry Site ç This guy is Canadian
We have a netnews group: rec.models.rockets
There is a UK equivalent
OK,
Запуски ракет — что интересно. [Mishka#20.04.07 22:25] - a lot of guys across former USSR are in rockets J I told that I can probably go to rocket launch site and they asked me to ask questions, take pictures and movies. If some questions are not "right" ones - just kick then out of list.
Legal part:
Any applicable laws, rules, procedures. Does government control it? Does such kind of activity required permits, registrations, etc?
For rockets with less than 62.5 grams, there are few Federal laws. One or two localities have problems, but most are fine. Larger rockets are regulated by several Federal agencies.
If there is an agency in control of it - what is the name of it?
Federal Aviation Administration
Bureau of Alcohol, Tobacco, and Firearms
Some agency that enforces the National Fire Protection Act
Department of transportation
I'm missing one or two, here. It is a highly regulated hobby here.
Fuel:
Solid or liquid type of fuel?
Mostly solid. Some hybrid. (Hybrid is synthetic rubber and N2O, mostly)
Is it possible to buy fuel or you have to make your own?
We can purchase loaded motors. We can purchase reloadable motors and propellant.
For larger rockets, the vendor appears at the launch site where the material is used.
(That way it is unnecessary for everyone to comply with storage and transport laws)
N2O is almost unregulated as long as it has SO2 in it so you don't breathe it.
If case if you are going to make your own fuel - where and how to buy it? Prices?
You have to have special permits to get and use the material.
There are a few such clubs, but not many. Some material can be found in obscure but unregulated sources (e.g.; Asian food stores for KNO3), but these are not the best chemicals, and their use in this context is illegal. Black powder is freely available because guns are protected here. Ironically, it is some of the most dangerous stuff to use.
Rockets:
One step or two step engine?
Most are 1-step, but have seen up to 3.
Is there a limit on rocket size?
Different sizes have different regulations. I have seen up to 40960 Newton-second impulse motors.
I heard of one twice that size, and was provided with data from it.
Safe landing system - do you use parachutes or something else also?
Parachutes. On large systems, a small chute deploys at apogee. A larger one deploys at ~150 meters.
How do you deploy parachutes? Spring? Pyro stuff (controlled explosion)?
Black powder, mostly.
When you build your own rocket - is it assembled from kit or is it homemade?
I don't build motors. I usually build from kits or pre-fabricated parts. I am interested mostly in data. Fire and smoke are not particularly attractive to me. I endure it to socialize.
Is there a site where I can take a look at different blue prints of rockets made by people?
I'll include some sites.
How do you attach stabilizers to a rocket body?
They are usually attached with epoxy, but the design plays a role in the strength as well. The fins are usually attached through-the-wall, for example. Sometimes fin canisters are used.
Electronics:
What kind of measuring electronics do you use?
The most common instrument is a combination of barometric altimeter and single axis accelerometer. These are used to gather data and also to deploy recovery devices. There are also 2 and 3-axis accelerometers, and GPS downlink devices. Sometime temperature sensors are used too.
Any controllers?
Most of us stay away from controllers. As long as we cannot aim the rockets, the government is less concerned about us than they otherwise would be.
How do you control heights, course, acceleration?
We simulate on a computer and make sure the performance will be within our altitude waivers.
Launch Pad:
Design, electronics, etc?
Rods or rails. We use remote electrical ignition.
