Job Description
OHB Sweden is a leading Swedish supplier of space systems. We develop build test and commission satellites and subsystems for space missions in for example communication earth observation and space research for institutional and commercial customers within and outside Europe.
OHB Sweden is currently developing a mechanical pressure regulator prototype with support of the European Space Agency. There is a need to simulate and better understand the transient response of the regulator.The regulator consists of the main regulation mechanism as well as ancillary components such as filters and a slam attenuator. The responsibility of the student is to study in depth the transient response of the regulator assembly through detailed modelling and by doing so evaluate ways of improving said response.
The tasks of the masters thesis topic are as follows:
- Evaluate and model the transient performance of a mechanical pressure regulator prototype and its ancillary components by creating a 1D performance model in the modelling software EcosimPro.
- Analyze the performance of the regulator assemblys constituent components using CFD and/or testing as input to the EcosimPro model (if deemed necessary).
- Validate the performance model by comparing its results with existing test data and if necessary perform additional flow tests as needed.
- Once a valid EcosimPro model has been established study how tuning individual parameters (spring coefficients orifice sizes discharge coefficients coefficients of friction etc.) may improve the transient response of the regulator and its ancillary components.
- Based on the results produced in the previous step propose design improvements to the regulator assembly.
- If time allows the student may also manufacture and validate the new design(s) through testing.
The required candidates skills are:
- Understanding of mechanical systems and fluid dynamics.
- Experience with CFD tools (e.g. ANSYS Fluent COMSOL) for component analysis.
- Skills in data analysis and model validation using test data.
- Strong problemsolving abilities to optimize system parameters.
- Selfmotivation and the ability to work both independently and in teams
- Excellent communication and presentation skills for sharing findings with both technical and nontechnical stakeholders.
What can we offer the student for them to succeed in their masters thesis
This is a unique opportunity to contribute to the advancement of satellite modelling and development while gaining valuable experience in the space industry. During the Master Thesis OHB Sweden is offering support and technical expertise from highly skilled motivated and innovative Propulsion engineers.
The Master thesis requires you to bein Stockholm at our office in Kista and cannot be done remotely.We follow the export controls law and this regulates which country of birth people who work on our projects may have. We at OHB cannot influence this law.
We look forward to your application!
