Tenders Are Invited For Miniaturised, High-Pressure Isolation Valve For Nanosatellite Propulsion - Expro Plus

Tenders are invited for Miniaturised, High-Pressure Isolation Valve for Nanosatellite Propulsion - Expro plus The objective of this activity is to develop a miniaturised, high-pressure isolation valve for nanosatellite propulsion.Description: Nanosatellite propulsion is a key technology to permit mobility and enhance utilisation perspectives of future nanosatellites. Propulsion enables orbit changes, drag compensation, station keeping, altitude maintenance, formation flying, proximity operations, precise attitude control, collision avoidance manoeuvres and disposal at end of life. Nanosatellite propulsion technology may also enable ambitious missions in Earth orbit such as constellation of small satellites flying in formation or space exploration missions to the Moon, Mars or Near-Earth objects (transfer, orbiting and even landing).There are no suppliers of high-pressure, miniaturised isolation valves in Europe. This may put an economic burden on the electric propulsion systems suppliers and can limit the information available for users if there are export or intellectual property restrictions on the dissemination of information relating to the valve design and / or performances.The valve to be developed within this activity shall be compatible with Xenon gas and Krypton gas (and other media), shall be capable to operate at maximum expected operating pressure (MEOP) of 180 bar for Xenon and 310 bar for Krypton and shall implement filter to protect the downstream flow from particulate contamination. Finally, it shall be designed to meet requirements of lifetime, reliability, leakage, pressure drop, low cost and series production of future nanosatellites.The activity shall include the following tasks: Requirements definition and review. Design definition and design justification via analysis and early lowlevel test. Manufacture of breadboard(s), performance testing and accelerate life cycle testing to validate design choices with krypton and xenon. Test readiness review, performance testing and accelerate life cycle testing to validate design choices with krypton (at 310 bar) and xenon (at 180 bar). Development plan to complete qualification and achieve flight readiness status.Read more Tender Link : https://esastar-publication-ext.sso.esa.int/ESATenderActions/filter/open
