Experiments at P8

The liq­uid Hydro­gene / liq­uid oxy­gene rock­et engine built by R. Müh­leisen GmbH for DLR Lam­pold­shausen has per­formed suc­cess­ful­ly first igni­tion and test run.

All com­po­nents where final­ly designed at RM includ­ing man­u­fac­tur­ing draw­ings bas­ing on a fun­da­men­tal design by DLR Lam­pold­shausen. Using the RM man­u­fac­tur­ing draw­ings the ele­ments of the engine where pro­duced at RM over a time peri­od of about two years. Here we com­bined a lot of man­u­fac­tur­ing process­es like turn­ing, milling, sparc ero­sion, gal­van­i­cal mate­r­i­al depose­ment, laser weld­ing and TIG weld­ing. The opti­mal com­bi­na­tion and organ­i­sa­tion of all need­ed process steps was the high chal­lenge dur­ing the man­u­fac­tur­ing process. The pic­tures above show the rock­et engine final­ly assem­bled, ready to be inte­grat­ed at the test facil­i­ty P8 ( pic­ture © by DLR).

The objec­tive for the tests at P8 is the devel­op­ment of new
com­bus­tor tech­nolo­gies and the improve­ment of cur­rent concepts.
Addi­tion­al­ly, basic research on the chem­i­cal-phys­i­cal process­es in
Hydrogen/Oxygen high pres­sure com­bus­tion is one of the key
issues of the sci­en­tif­ic work at P8. The results obtained from these
tests at P8 will also be used for the ver­i­fi­ca­tion and val­i­da­tion of
recent­ly devel­oped sim­u­la­tion tools for the numer­i­cal sim­u­la­tion of
the ther­mo­dy­nam­i­cal and flu­id-mechan­i­cal prop­er­ties in
Hydro­gen/Oxy­gen-rock­et com­bus­tion chambers.
