- Safety of
Nitrous oxide N2O
in rocketry. Presentation
given in the frame of the
4th AMRAS symposium. PDF english,
PDF
german, also have a
look at Rick Newlands
great paper about hybrid
safety
(mainly nitrous related
stuff)

- Ignition!:
: An informal history
of liquid rocket
propellants, by
John D. Clark. Probably
one of the most important
book for people involved
in liquid rocket
propulsion. Very
informative but also very
entertaining. Out of
print, but it can still be
ordered as a reprint from
UMI.
We scanned and edited it
because we wanted it in an
electronical form, so we
can search in it. Since
it's still copyright
protected we only grant
access to this dokument
for our internal members.

- Project
Enterprise.
In the frame of the
recently started project
ENTERPRISE with our
partner Talis-Institut
(sorry, you will see
nothing if Javascript is
disabled) we wrote a
german overview of our
work. Just go to the
Talis webpage and choose
the link to the Project
Enterprise (sorry, no
permalink on the site)
and our report in the
september edition of the
Talis online magazine T.I.M. (A
local copy of our
article: as a HTML

document)

Student
projects:
|
- Development of
a water-cooled rocket
nozzle
(Mark
Vujicic and Justin
Mercier at HEPIA
2016). The job
includes designing the
nozzle, its cooling
jacket as well as the
outer shell which
houses all the
components. The whole
construction will have
to fit in to the
combustion chamber,
which already exists
and was developed by
SPL. To help with
choosing the most
optimized cooling
settings, different
simulations of the
nozzle were run using
mainly three
software's (PTC Creo
Parametrics, Rocket
Propulsion Analysis
and ANSYS Fluent
14.5).. The
full report as PDF 8
MByte (including
workshop drawings) .
Designing
and building of
a stage
separation
mechanism (Thesis
of Mr. M.
Vögelin and
Mr. P. Frey at
FHNW (former FHBB) 2007). The
students
worked out
several
variants for a
stage
separation
mechanism
which can be
used on
rockets with a
diameter of
300 mm like
X-Bow I or
AUSROC 2.5. It
can also be
used to deploy
recovery
equipment.
Thsi is the
final desgn.
The full
report as PDF
5 MByte,
german
(without
workshop
drawings) .
Handout as presented at the exhibition. See the news
entry from 21. February 2007
- Construction
of a Curtis impulse
turbine to drive
turbo pumps (Thesis
of Mr. L.
Lehmann and Mr.
M. Kneier at FHBB, 2006). The full report will be available soon.
- Designing
and building of a
stage separation
mechanism
(Thesis of Mr. C.
Schulthess at FHBB, 2006).
This is a
continuation of
the last years
work. The full
report will be
available soon.
- Designing
and building of a
stage separation
mechanism
(Thesis
of Mr. R.
Buser and Mr.
A. Maritz at FHBB, 2005). The
students worked
out several
variants for a
stage separation
mechanism which
can be used on
rockets with a
diameter of 300
mm like X-Bow I
or AUSROC 2.5.
It can also be
used to deploy
recovery
equipment. The full report as PDF 10 MByte, german (without
workshop
drawings) .
Handout as presented at the exhibition.
- Construction
of a test bench for
small turbines (Thesis
of Mr. A.
Hostettler and
Mr. F. Jacot at
FHBB, 2005). The goal
of this student
project at FHBB
was the design,
building and
testing of a test
bench where
modified turbines
of automotive
turbo chargers can
be tested as a
power plant for
turbo pumps. Our
long term
intention is a
small low cost
turbo pump for
small rocket
engines. Interim
report: PDF-File,
1.3 MByte, German, Final
report (2 MByte,
German, without
workshop drawings),
Handout as presented at the exhibition.
- Designing,
building and
testing of a
regenerative
cooled combustion
chamber with 2.5
kN/560 lbs thrust
(Thesis
of Mr. G. Ermini
and Mr. F. Kaiser
at FHBB,
2002). The
students have
analysed the heat
flux through the
chamber walls and
the heat transfer
into the coolant
(water, kerosene
and pure ethanol)
. They have also
developed a code
to optimise the
size and shape of
the cooling
channels. PDF-File,
2.3 MByte,
German Addendum:
There are some
miscalculations
in the heat flux
calculations!
- Analysis
of the behavior of
various injection
systems in a
high-pressure
environment
(cold spray test
into a chamber).
Investigation of the
size, speed and
distribution of
droplets injected into
a test chamber (Thesis
of Mr. Martin
Lüthi and Mr.
Christian Muser at FHBB, 2000) PDF-File,
1.4 MByte, German

Patents |
- Device for Pressurizing
Propellant Tanks (Patent pending)
After a
series of successful prototype
tests we filed our first patent
application for a new Tridyne
pressurization system, with a wide
commercial and military
application area. The patent has
been lodged at the Swiss Federal
Institute of Intellectual Property
at the 16th February. It is
thought to be flown in ASRI's AUSROC 2.5.
A brief description can be found here.
