LUMEN Turbopump - Preliminary Design of Supersonic Turbine

Kurzfassung

This paper presents an improved design methodology for a supersonic partial admission impulse turbine for LRE, which is commonly used in open cycle applications, while focusing on the main losses from small dimension as well as the high rotational speed required for low thrust class engines as the LUMEN demonstrator engine. Also, the standard design models are evaluated and compared with the results using the design constrains adopted for low thrust class level turbomachinery.
