Objectives
The objective of this activity is to perform qualification level tests with an engine fitted with the chemical thruster valve (CTV-D) in order to validate the application for a commercial satellite programme.
Description
The proposed activity is built on the results of T119-604MP ? Chemical Thruster Valve (Dual) (CTV-D) Development, which has successfully completed a development programme, including a full qualification test campaign at valve level. ;
The objective of this activity is to fit this valve to the advanced monopropellant thruster, currently nearing the end of its qualification test campaign, to replace the non European supplied valve currently fitted.
The valve and thruster will then undertake a campaign of tests to demonstrate the performance and suitability to meet foreseen requirements.
The expected test campaign includes:
- Functional testing of the engine (engine hot fire testing with live propellant in a vacuum chamber, back pressure relief function, filter silting tests).
- Environmental testing (vibration, shock, thermal vacuum test).
- Electrical performance (magnetic dipole).
- Update the definition of the electrical interface of the valve to meet the requirements of the application programme (twisted wires). ;
;
The successful test campaign will have demonstrated the overall suitability of the valve to meet the requirements of the thruster performance for the application, but also demonstrate the industrialised manufacturing and acceptance testing of the valve product as a repeatable flight component, rather than the one-off prototyping methods and techniques employed up to now.
