Digital twin driven autonomous maintenance for aerospace applications PhD

This exciting PhD focuses on cutting-edge aerospace maintenance technology. 

Autonomy is becoming a focal point for aerospace research. Whilst this was traditionally achieved by modelling self-engineering behaviours at the component-level, efforts need to focus on sub-system and system-levels through advancements in artificial intelligence. Exploiting its benefits requires some innovative thinking to integrate overarching concepts from sensing, digitisation, state estimation, optimisation, control and systems engineering. With recent requirements in aeronautic and astronautic systems, there has been a growing interest in adapting these concepts to achieve autonomy during concept design, operational service, the automation of predictive maintenance scheduling directly from operational data and for in-built repair at the systems-level. Through a digital condition assessment, on the actual system's components, the project will resort to innovative technology to trigger self-repair; to extend properties life-cycle and lifespan, and improve efficiency to maintain high performance.

Aim

The aim of the PhD is to investigate the application of autonomous maintenance. It focuses on the following research questions: 
• Can a digital twin introduce autonomy for self-maintenance?
• What are the requirements for such a digital twin driven framework?
• How can this concept be realised for aircraft engine components?

The project will need to encompass lots of concepts and technologies; Internet of Things (IoT), big data analytics and machine learning. Consideration should be given to these concepts, and the scalability for future technology. The project will consider the information or data that needs to be collected within the context of maintenance e.g. what data, where from, who for, what for?

The technology will facilitate Prognostics and System Health Management (PHM) in different areas such as a) AI-based diagnostics and prognostics, c) Autonomous decision-making, and d) Self-healing or repair. Each of these areas has quite distinct skills set and behaviours associated with them. 

Objectives

1. Determine in-situ implementation complexity requirements;
2. Determine the required levels of autonomy for PHM of aircraft engine components;
3. Addressing the technological barriers, i.e., lack of computation, knowledge representation, network performance, interfacing and communication;
4. Validation of the concept in the aerospace environment.

At Cranfield, the candidate will be based at the Centre for Digital Engineering and Manufacturing, which hosts cutting-edge simulation and visualisation facilities. The student will have access to high-end computers for simulating the complex nature of maintenance. There will be relevant visits to various organisations throughout the PhD to develop and demonstrate the research.

Job Opportunity Potential

The Career Development Service is an important part of the Student Experience support function. Our team has significant real-world experience in the areas of coaching, recruitment, human resources and business development. We help students develop their personal career journey, so they can find meaningful employment that utilises their Cranfield qualification.

If you are an international student, it is important to be aware of the visas required to work in the UK and abroad after graduation. The following information should act as a signpost to resources, so that you can research your options thoroughly.

Working in the UK after Cranfield
In a major boost for international students, the UK Government has announced a new Graduate route, expanding opportunities for international students to build successful careers in the UK. All international students who join Cranfield in the 2020/2021 academic year will be eligible for the new scheme.

Launching on 1 July 2021, this route will be open to all international students who have a valid UK immigration status as a student and have successfully completed their course at Cranfield. The visa will allow eligible students to work, or look for work, in any career or position of their choice, for two years ( for MSc students) and three years (for PhD students) after completing their studies. During the period of their visa, they will be able to switch onto the ‘skilled work visa’ if they find a job which meets the skills requirements of the UK Government.

Resources for Employers
Cranfield University creates global leaders in technology and management, we are renowned for having a rich student body from culturally diverse backgrounds. With their combination of academic excellence, research capabilities and knowledge of real-world applications, they are able to make valuable contributions to commercial objectives.

For information on sponsoring someone as a Skilled Worker or on a Tier 5 visa, employers should visit the UK Visas and Immigration's guidance for employers. As a student, it is useful to be aware of this, should a potential employer have any questions.

Making your business case to Employers
In order to be successful with any application for employment, you will need to provide evidence for your skills and abilities, as well as demonstrate your career motivation. We have a Learning Pack dedicated to the art of filling in an Application Form, which can be downloaded here; and a Factsheet on Speculative Applications which can be found here.

We would also recommend that you take the time to write a compelling Cover Letter, outlining the type of permit that you are looking for and any steps an employer would need to take in order to hire you. The Learning Pack related to this topic can be found here.

Finally, to be totally proactive and generate your own opportunities, you should read up on The Hidden Jobs Market to discover how to find roles that aren’t advertised; you can download our Factsheet on this here.

National Insurance Numbers
You need to have a National Insurance number if you’re planning to work in the UK. You can start work without one if you can prove you have the right to work here. You do not need a National Insurance number to apply to the EU Settlement Scheme.

Resources for International Students
We have teamed up with Student Circus to help our international students find employment in the UK.

All employers on the site are:

  • confirmed as willing to sponsor the UK Work Visa
  • verified as offering salaries as per immigration rules
  • licensed with the Home Office
  • able to provide expert immigration advice

By using the site, our international students can expect to:

  • get prepared for the UK job market and build a network
  • discover structured and formal paid internships designed with flexibility
  • improve their chances to get a job with the same company
  • All Cranfield students will receive a log-in to Student Circus once they arrive on campus.
