Thrust Chamber Components

Sienna announces the development of the ultra-high temperature FGM composites for HAN-based advanced green monopropellants. The new FGM material combines workability of metals with high temperature resistance of ceramics. Together with our existing “Black Pearl” or SSC-105 ultra-high temperature materials, the new FGM material can revolutionize the industry by replacing expensive iridium coated refractory metals for bed plates and thrust chamber construction for chemical propulsion.

Sienna-SSD using its advanced materials expertise and state-of-art manufacturing capabilities has developed:

● Ultrahigh temperature lightweight thrust chambers,  thrust chamber coatings, and bed plates for high performance chemical propulsion systems powered by ionic liquid based advanced green monopropellants;

● High thermal conductivity anode and cathode isolators, and erosion resistant plasma wall liners for high power electric propulsion (EP) systems. Recently, we have demonstrated a new ceramic material for plasma channel insulators for high power Hall Thrusters with lower SEE yield than the State-of-Art BN materials.

● High temperature     (1600°C) stable cathode heaters for EP  thrusters are currently under development.
