“…Italy has also supported since long time the future evolution of VEGA, starting with ASI national Programs such as Lyra, fostering the introduction of a larger liquid propulsion upper stage exploiting LOX-CH4 propellant combination substituting Z9 and AVUM. In the frame of Lyra program, the basis for mastering this technology have been set up through a collaboration with Russia leading to the firing test of a 10 ton class engine demonstrator called MIRA [7]. Those achievements have been the basis for introducing within the ESA programmes the VEGA Evolution Preparatory Program aimed at developing VEGA-E that, starting form VEGA-C configuration, will substitute Z9 and AVUM+ with a new upper stage making use of M10 engine, developed in the frame of the same program.…”

Space transportation systems are the key elements for the space exploitation thought space-based services (for telecommunication, navigation and earth observation) and space exploration. As more government and commercial players show interest in effective and sustainable space transportation systems and services, affordable, regular and resilient transportation systems have become increasingly important for sustainable space services. Italy, thought the activities of the Italian Space Agency, is increasingly investing in the space sector and it confirms to be one of the top players on the international scenario. The paper presents an overview of the activities of the Italian Space Agency in this sector, both through national and European framework.

“…Until recently, only two engines have proved to be reusable: The Space Shuttle Main Engine (SSME) (LOX/LH2) and the Merlin engine (LOX/RP1). Nowadays methane is in discussion as a propellant for a new generation of reusable rocket engines because it may have advantages over both combinations [1,2].…”

Methane has many possible advantages as a fuel for reusable rocket engines and is therefore extensively discussed. However, the characteristics of methane as a coolant in a regenerative cooling system are widely unknown. Especially the heat transfer deterioration that occurs in the vicinity of the critical point is a major concern and a severe drawback. To investigate this phenomenon and to establish a broad data basis for the validation of numerical simulations, tests were performed with a subscale combustion chamber. The combustion chamber contains different cooling channel geometries (rectangular cooling channels with the aspect ratios [height-to-width ratio]: 1.7, 3.5, 9.2, and 30) and was cooled with cryogenic methane. Results close to the critical point show a distinct maximum in hot gas wall temperature, which is a clear evidence of heat transfer deterioration. The test results indicate a strong dependency on the occurrence of this effect toward cooling channels with a low aspect ratio.
