Chemical Propulsion


With its twenty-year heritage in cavitation and with the realization of the Cavitating Pump Rotordynamic Test Facility (CPRTF), SITAEL has gained a leading position and unique experimental capabilities for the characterization of unsteady flow phenomena and rotordynamic forces in rocket propellant turbopumps under fluid dynamic and thermal cavitation similarity. Principal areas of involvement also include the development of low-thrust green propellant rocket engines and high-enthalpy aerothermodynamics.

Cold Gas Micro-propulsion System

SITAEL’s Cold Gas Micropropulsion System has been designed for microsatellite platform of the order of 10 – 100 kg. The technology used for microthruster realization is based on MEMS microdevice. The low impulse bit achievable makes the system suitable to perform a very high resolution and pointing accuracy.

Propellant Feed Turbopumps

By exploiting the unique capabilities acquired through the realization of its Cavitating Rotordynamic Pump Test Facility (CPRTF), SITAEL has the capability of full design, development and testing of Inducers and Radial Pumps (Radial Impeller/Diffuser/Volute) by means of reduced-order models for performance prediction and preliminary design of tapered inducers and radial impellers focused on cavitation control design and efficiency maximization.


Green Propellant Rockets

SITAEL chemical propulsion team focuses on the development of low and medium thrust green propellant rockets for spacecraft and missile reaction control systems, based on Hydrogen peroxide (H2O2) and advanced catalysts/ceramic beds for rocket-grade hydrogen peroxide decomposition.
