I live in Ireland and am really into space and rockets, things like that. Unfortunately, materials like potassium nitrate are banned in Ireland which means it is really difficult to make your own homemade solid rocket fuel. I contacted the Department of Justice and they just referred me to a man named Eric Stenzel who runs an amateur rocketry club near Galway.
I emailed him during the Summer of 2017 to see what I could find out about the club and rocketry in Ireland. I found some useful information.
"We have a group of people that get together a couple of times each year to launch rockets but have been a bit quiet the last year."
"Rocketry in Ireland is regulated as the rocket motors are classified as explosives. When we have launch meets, I generally take care of all the licensing and import to make it easier on everyone."
"Our meets are in Tuam, Co Galway as our high power rockets need a few miles of open space."
"Low power rockets are the ones I like the most. These use gunpowder-based motors to fly. The motors are industry manufactured and resemble shotgun shell size and shape."
"Going up to mid and high power rocketry, the fuel is APCP (Ammonium Perchlorate Composite Propellant). This is the fuel that launched the space shuttle in the solid rocket motors. It is an oxidizer mixed with a polymer composite. Oxidiser + fuel + reaction = rapid expansion of gas - rocket boast."
"With standard motors, the rocket can fly multiple times with the replacement motors. If you want to experiment with your own motor chemistry, you can import the needed chemicals under license - but you have to be 18 to handle explosives. Sugar motors are used quite a bit but the purchase of potassium nitrate needs to be under DOJ license."
"Hybrid rockets are actively used in the world of rocketry but we have yet to use them in Ireland. You're welcome to be the first!"
"We do have an altitude limit of 100,000 feet - but no one has touched this level yet. We (Ireland) have the highest altitude limit waiver in the world on a continuous basis but no one has touched this limit - yet. The highest flight in Ireland to date is just over 15,000 feet - just under 3 miles."
"we use GPS systems and altimeter control units. GPS is a great help in finding the rocket when it lands. It is frustrating at times where the wind carries a rocket as it descends. Altimeters are used to control the deployment of parachutes. a very small parachute is deployed at apogee (When the rocket reached maximum altitude) and a larger one when the rocket is 400 - 500 feet from the ground. We do not deploy the large parachute at maximum altitude as the rocket would drift to Germany when it hits the ground
That is all the information I have at the moment but if I find more I will definitely add it here.
