Job Description

Valves are critical components in spacecraft propulsion systems, where high reliability, low mass, and efficient operation are essential. OHB Sweden is currently investigating a new valve concept for future space applications and is seeking a Master's student to support the early stages of the product development.

The thesis will focus on establishing a preliminary product definition, identifying key requirements, evaluating design concepts, and performing first-order sizing and analysis of critical components and operating parameters. Depending on project progress and thesis scope, the work may also include the design, manufacturing, and testing of an initial prototype.

Job overview

Are you interested in contributing to the development of hardware for future space missions? OHB Sweden is looking for a Master's student to support the early development of a new valve concept for spacecraft propulsion systems.

During the thesis, you will work with the complete early-stage development process, from defining requirements and evaluating design concepts to preliminary sizing, modelling, and engineering design. The work will involve balancing key considerations such as performance, reliability, manufacturability, mass, and power consumption. Depending on the progress and final scope of the thesis, you may also have the opportunity to design, manufacture, and test a proof-of-concept prototype.

You will carry out the thesis as part of OHB Sweden's propulsion team, working closely with experienced engineers and contributing to the development of technology intended for future space applications.

The tasks of the master's thesis topic are as follows

The student will contribute to the early development of the valve through activities such as:

• Identification and analysis of applicable requirements.
• Functional analysis and product definition.
• Evaluation of alternative concepts and design solutions.
• Preliminary sizing and modelling of critical components and operating parameters.
• Assessment of performance, reliability, manufacturability, mass, and power consumption.
• Development of a preliminary engineering design.
• Design, assembly, and testing of a proof-of-concept prototype, if time permits.

The required candidate’s skills are

The position is suitable for Master's students in:

• Aerospace Engineering
• Mechanical Engineering
• Mechatronics
• Electrical Engineering
• Engineering Physics
• Applied Physics
• Or a related engineering discipline

Experience with CAD, simulation, product development, testing, or modelling is considered beneficial but is not required.

What can we offer the student for them to succeed in their master's thesis?

The student will become part of OHB Sweden's propulsion team and contribute to the development of a new spacecraft propulsion technology. The work offers hands-on experience with real hardware development and close collaboration with engineers working on current and future space missions.
