Vibration Attenuation and Damping Enhancement of Lightweight Composite Turbine Blades for Renewable Energy Applications

Summary

Renewable energy technologies rely on lightweight, durable, and efficient turbine blades that can operate under challenging dynamic loading conditions. Excessive vibration can reduce structural performance, accelerate fatigue damage, and increase maintenance requirements, creating a need for innovative solutions that improve both reliability and energy efficiency.

This PhD project will investigate the vibration behaviour and damping performance of lightweight composite turbine blade structures for renewable energy applications.

The research will explore advanced structural concepts and composite materials to enhance vibration attenuation and energy dissipation while maintaining lightweight design characteristics.

The successful candidate will develop analytical and computational models to predict blade dynamic behaviour and examine the influence of geometry, material properties, and structural configurations on vibration response.

Experimental work will be conducted at Ulster University and will include vibration testing, modal analysis, and damping characterisation of representative composite blade structures.

The resulting data will be used to validate numerical models and improve understanding of the mechanisms governing vibration reduction and structural durability in composite turbine blades.

The project will be undertaken in collaboration with ÉireComposites, providing exposure to industrial design practices and real-world engineering challenges associated with composite structures for renewable energy applications.

Through regular engagement with industrial experts, the researcher will gain valuable insight into the design requirements and performance expectations of next-generation wind and tidal turbine blades.

The successful candidate will develop expertise in structural dynamics, vibration analysis, composite materials, finite element modelling, experimental testing, and renewable energy engineering.

The project is suitable for graduates in Mechanical Engineering, Aerospace Engineering, Materials Engineering, Civil Engineering, Applied Mechanics, or closely related disciplines.

Essential criteria

Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.

We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.

In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.

• A comprehensive and articulate personal statement demonstrating interest in the subject area
• Experience using research methods or other approaches relevant to the subject domain

Desirable Criteria

If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.

• Applicants should hold, or expect to hold a First Class Honours Degree in a relevant subject area
• International applicants should hold, or expect to hold a relevant Masters Degree at a level equivalent to a distinction at Ulster
• Experience or knowledge of research methods or other approaches relevant to the subject domain
• Work experience relevant to the proposed project
• Track record of peer reviewed publications

Equal Opportunities

The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.

Appointment will be made on merit.

Funding and eligibility

This project is funded by:

• Department for the Economy (DfE)
• Vice Chancellor's Research Scholarship (VCRS)

PhD scholarships are available for this project to all applicants worldwide, regardless of residency or domicile, and will cover:

• Tuition fees.
• A maintenance allowance of approximately £22,000 (exact rate is to be confirmed) per annum for three years, subject to satisfactory academic performance.
• A Research Training Support Grant (RTSG) of approximately £900 per annum.

Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year, or part-time equivalent, funded from any source, including self-financing students, are NOT eligible to apply for an award.

Students in full-time employment are not eligible for an award.

Part-time PhD scholarships may be available at a 0.5 pro rata rate of the full-time scholarship, which would require a six-year registration period.

Due consideration should be given to financing your studies.

The University will award a successful candidate one of the following scholarships for the project, depending on the funding available at the time an admissions offer is made:

1. Department for the Economy (DfE) PhD Scholarships
2. Vice Chancellor’s Research Scholarships (VCRS)

Please note that the Terms and Conditions for scholarships are subject to change for 2027/28.
