Uploaded 20 Apr 2021
Neutron Star Systems UK Ltd is a space start-up pioneering the use of High-Temperature Superconductors for spacecraft applications. NSS main product is an exciting new electric propulsion technology. Our SUPREME thruster is an Applied-Field Magnetoplasmadynamic thruster (AF-MPD), which has been researched globally for over 60 years but has been held back by the high mass of the electromagnets needed to generate strong magnetic fields. New technology in the form of super-powerful high-temperature superconducting magnets promises to overcome this issue and revolutionise the economics of space operations. Three key advantages are offered by AF-MPD technology: (i) Very low propellant costs (ii) Enormous scalability with minimal mass and volume penalties (iii) A wide throttleability range over several operating conditions.
The company has built a knowledge network and partnerships with other specialist technology businesses over the past 3 years from its parent base in Germany. Neutron Star Systems UK Ltd. is the company’s UK office, focussed on the development of the superconducting coils, cryogenic systems, and power electronics for the thruster. NSS UK it currently participating in the Westcott Business Incubation Programme.
Using Neutron Star Systems own literature database plus specialist material available on-line (eg ESA), the applicant will research candidate cryogenic technologies for use with the NSS SUPREME thruster.
The goal for the applicant is to establish the outline requirements for the cryogenic system and how these requirements will differ over a range of thruster power classes (e.g., 5kW, 20kW, 50kW, 100kW). The applicant will identify the various components utilised in different cryogenic system technologies and define the preliminary design and parameters of such components for the various power classes. In addition, the applicant may explore system integration considerations of the cryogenic system within the thruster and supporting technologies which can improve the performance of the system.
This will require developing an understanding of:
- How cryogenic systems operate to provide low temperatures for cryogenic components
- How different cryogenic technologies are suitable for different applications depending on the operating temperatures and heat loads
- How the needs of different thruster power classes impact the requirements of the cryogenic system
- How different design considerations and enabling technologies on the side of the superconducting coil can affect the requirements of the cryogenic system
- How the cryogenic system can be integrated within the thruster and also within an overall spacecraft system.
The applicant needs to prepare written reports and evolve written specifications, starting with on-going rough working notes on-line and regular reviews and discussions at least weekly with his/her supervisor in a friendly, supportive manner via video and telephone calls.
An enthusiastic engineer or physicist in any of the following disciplines: Mechanical Engineering, Aerospace Engineering, Thermodynamic Engineering, or Physics with Thermodynamics
- Thermodynamics and/or Physics Background (practical or academic), Final Year Bsc or Masters Student
- Self-starter attitude and initiative; someone who recognises and is excited by involvement in a start-up space business and will readily adapt themselves to whatever challenges arise.
