| Popis: |
In the frame of the LYRA Program, funded by the Italian Space Agency, the LM-10-MIRA engine has been successfully tested. The engine has a vacuum thrust of 10-tons and has been developed by a joint Avio-KBKhA propulsion team in the frame of a dedicated ASI-Roscosmos inter-agencies agreement. After the experimental test campaign, further improvement for flight application have been identified, including the improvement of the efficiency and new technologies for of injector head manufacturing. The `lesson learned\' allowed ASI to promote further activities in collaboration with Avio. In particular, two main activities have been developed, the first one aimed to reduce the methane line pressure drop and the second one related to the optimization of the methane/oxygen interfaces. The results have been implemented on a subscale version of the injector head. The present work describes the improvements obtained and confirmed by the results of the subscale experimental test campaign. |
