Alta's newly designed 5 N "green" monopropellant thruster demonstrator reached 42 min. total firing time during its first series of endurance tests on advanced catalytic beds.
The first turbopump inducer built by Alta demonstrates the validity of its newly-developed design method.
Alta's successful spin-off case to be featured at the "Space SMEs in Europe" meeting in Rome, May 11-12.
Successful operation of Alta's green monopropellant thruster demonstrator
Operating with environmentally friendly hydrogen peroxide, Alta's 5 N "green" monopropellant thruster demonstrator for advanced catalytic bed development recently cumulated 42 minutes of firing time and a total impulse of 12500 Ns.
Successful endurance tests have been carried out by Alta's Chemical Propulsion Team on a series of hydrogen peroxide decomposition beds developed in-house. The engine catalyst LR-III-106 (shown on the left in the picture above) showed excellent performance, decomposing a total of 10 kg of H2O2 at 90% concentration with temperature efficiency in excess of 95% and characteristic velocity efficiencies approaching 100%.
