Hi Malte,
thank you for your detailed response !
- All boundary conditions mentioned (costs, formal procedures,
application for launches, availability of propellants) sound quite
interesting.
- However, after having a look at the map I got a 'bit of a headache'
:-) after noticing quite a few small towns within a radius of about 15 -
20 km. In a distance of about 1 - 2 km streets could be found.
=> How will this fit into the safety concept when launching rockets up
to 10 - 100 km ?
=> For sure I am aware of the obligation to use a flight termination
system. However I assume, that this is a very critical issue considering
populated areas in the close vincinity. How will the proper
functionality of the flight termination system have to be proven to the
responsible authorities ? (To my understanding this will be an
especially critical issue in case of using a non-commercial system.)
Eventually I am a bit 'over-pessimistic' - this might be due to very
long and extremly tireing discussions with the authorities over here in
Germany to receive permission to launch SRM propelled amatuer rockets up
to 5 km !
(Yes, FIVE km .... a really small number !! However - even though when
planning to do the launch at a military prooving ground they did insist
on a full circle, 360 ° safety radius in case of using solid rocket
motor propelled vehicles. (Ballistic safety range of 2-fold maximum
altitude, considering the worst case scenario of the rocket launching at
45 ° due to some malfuction. )
Using a flight-termination system I also did propose, but this did turn
out to be an at least 2-year discussion with completely unknown outcome.
To summaruze the situation in few words: launching to altitudes greater
than 1 - 2km over here is practically impossible for amateur projects.
Even companies trying to do so will have a really hard time to succeed.
Well - still hoping for good news :-) - best regards,
Peter

Hi,
I hope this mail will answer some of your questions.
Coordinates of launch site:
63°38.20', 17°56.34'
https://kartor.eniro.se/?c=63.636732,17.939043&z=15&l=aerial
Costs:
The cost depends on several factors and may vary greatly from launch
to launch.
Some of the factors are:
Number of launch windows
Maximum altitude
Which propellants and chemicals used.
If the local fire department must be on site and for how long.
Personnel costs
Handling fees
Road closure fees
A launch permit for a sounding rocket using LOX/LH2 with the
dimensions you describe with a maximum altitude of 100km will cost
around €1000-€2000. Handling fees and road closure fees will be added
to the total (about €250/day).
Flight Termination System:
Small, low-altitude rockets do not need FTS (up to 11 000 meters).
Larger liquids and hybrids must be able to shut off the engine(s) in
flight. Solids must also be able to terminate the thrust (how is
entirely up to the customer).
Propellants:
Other propellants than those I specified earlier may be possible to
deliver to the site. (I'll see if I can arrange LCH4).
Regarding HTP, I can definitely arrange larger quantities if needed,
but for now the limit is 20kg/month. The peroxide is stabilized with
sodium stannate.
Regards,
Malte

Hi Malte,
eventually having available a space port usable for low cost
launch projects in Europe indeed is really good news ! Some
questions about this:
- is it possible to send the exact coordinates, so the site could
be looked at on google maps ?
- is it already known, which formal effort will be needed to
launch up to 30 or 100 km ? (I think the last questions has been
asked by another list member 1-2 days ago... . ) When trying to
launch in Kiruna (Sweden) or Andoya (Norway) it seems like the
paper work will keep busy at least two engineers for half a year.
This effort will be barely possible to invest for most of the low
cost projects.
- what kind of flight termination system will be needed ?
- depending on the formal boundary conditions testing a sounding
rocket using LOX / LH2 or LOX / LCH4 would be interesting.
(Diameter: about 500 mm, Length: about 5 m) 100 km max.
- how high the launch fee approximately would be ?
- might LCH4 also be available ?
- HTP is interesting for the RCS under consideration: 20 kg /
month is not very high a quantity: eventually the quantity could
be increased ? HTP available will be free of stabilizers, so it
can be used with Ag based catalysts, I assume ? Eventually HTP up
to 98 % also might be available ?
Have a good day - best regards,
Peter

It's now more than two years ago I wrote a message to all of
you that I planned to establish a launch site in northern
Sweden. After many ifs and buts, I finally found a private
investment company that owns an old air force base of
approximately 30000000m2! This site includes several concrete
pads, törebodabågar and a runway of 2228 meters in good
condition. This means we will be able to host rocket launches
from March 2019, the application must be submitted to me no
later than 1½ months prior to scheduled launch to ensure we
have time to get all the necessary permissions before launch.
A launch application can contain a number of dates and times
over a 30-day period, which means you can perform several
launches with the same permission.
The following propellants are available upon request
Oxidizers:
Liquid oxygen
Anhydrous nitric acid
HTP(80-90%) - Smaller amounts of only 20kg per month are
available
Fuels:
Liquid hydrogen
Aniline
Triethylamine
Tetramethylethylenediamine
Ethanolamine
Morpholine
Isopropanol
