News around SPL
firing with the regenerativly cooled 2.5 kN LOX/Ethanol engine!

students of FHBB
(University of applied science Basel), Gianni Ermini
and Florian Kaiser, finished their diploma thesis, made in
the frame of a research program at SPL and presented the results
in a public exhibition. The focus of their work was on designing,
building and testing of a regenerative cooled combustion chamber
with 2.5 kN/560 lbs thrust (see also the news entry of 10th
November 01). 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.
Following a low cost approach, the combustion chamber was
made of aluminium. Their diploma thesis can be downloaded
(german!). In the meantime we at SPL upgraded the test
stand, so it is now fully operational for LOX/hydrocarbon
with tank pressures up to 5 MPa. Finally we successfully fired
the chamber 28th December 2002. A veritable firework for new
year's eve and we hope a god omen for the New Year :-)
an ongoing partnership of SPL with FHBB it was decided, that
a next step will be the design of a small, low cost turbopump.
The project starts with a radial inflow turbine derived from
a automotive turbo charger.
