Doctoral student in turbomachinery aeroelasticity - Hiring in process/Finished, not possible to apply

Project description

Third-cycle subject: Energy Technology

Modern high performance aircraft engines have highly loaded components, both mechanically and aerodynamically. Aeromechanical blade vibrations present a significant challenge in new designs as well as in operation, and managing such aspects constitutes a major portion of the blade design work. Mastering this successfully enables engine designs with improved efficiencies and lighter components. In operation, vibrations that occur often result in high maintenance costs and sometimes can lead to availability problems affecting end users. In the worst case, safety can also be compromised, followed by flight restrictions as a consequence. Identifying root causes and suggesting effective measures in a short period of time therefor becomes even more important. The aim of the project is to improve the current understanding of the physical processes that cause destructive blade vibrations in aircraft engines and improve the current design tools that are employed to predict and analyse these vibrations. The area is developing fast with more advanced opportunities available in the simulation tools; however, there are areas where the tools are still inaccurate or not validated. The project focuses on one of these areas, namely flutter in separated flow, where the project aims to generate detailed high quality measurement data through wind tunnel experiments for validation of CFD predictions.

The turbomachinery cluster at the Department of Energy Technology, which this project falls under, is a well-established research group with many years of experience from both EU projects, national program research and commissioned research in collaboration with Swedish and international industry and/or academia. The applied research often involves some experimental rig in the department, as in this project. This research project is part of the Swedish National Aviation Research Program (NFFP7) with funding from Vinnova. Reporting is made to partner company, and further to NFFP7 (Vinnova).

What we offer

• The possibility to study in a dynamic and international research environment in collaboration with industries and prominent universities from all over the world.
• A compulsory individual study plan to support your development in your area of interest.
• A workplace with many employee benefits and monthly salary according to KTH’s Doctoral student salary agreement.
• A postgraduate education at an institution that is active and supportive in matters pertaining to working conditions, gender equality and diversity as well as study environment.
• Work and study in Stockholm, one of Europe’s fastest growing capitals, which is close to both nature and the sea.

Eligibility

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a degree at advanced level,
• completed course requirements of at least 240 higher education credits, of which at least 60 higher education credits at advanced level, or
• in any other way acquired within or outside the country acquired essentially equivalent knowledge.

The applicant must have a strong knowledge in aerodynamics and aeromechanics in turbomachinery, demonstrated through relevant degree program/courses and/or relevant work experience.

Selection

In order to succeed as an doctoral student at KTH you need to be goal oriented and persevering in your work. In the selection of the applicants, the following will be assessed:

• ability to independently pursue his or hers work,
• ability to collaborate with others,
• have a professional approach and
• analyse and work with complex issues.

Experience of experimental testing and design of experiments are merits.

After the qualification requirements, great emphasis will be placed on personal qualities and personal suitability.

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
