Project Work Plan

WP1 Project Management & Coordination

WP Leader: UoS 
Other contributor(s): All
Coordination of the technical activities of the project in addition to management and administration of the project.

WP2 Aero-elastic code development and performance

WP Leader: TUD 
Other contributor(s):Cener
In this work package an aero-elastic model capable of capturing the dynamics of the X-Rotor concept will be created and validated. Performance loads and energy capture of the X-Rotor concept will be evaluated and aerodynamic noise analysis will be carried out.

WP3 Control and Operational Strategy

WP Leader: UoS 
Other contributor(s): TUD
In this WP, the operational strategy for X-ROTOR will be determined and the controller that realises this operating strategy will be designed. The pitch of the upper blades of the primary rotor and the rotational speed of the primary rotor and each secondary rotor can all be regulated independently. The design of the operational strategy and the controller will need to exploit all of these aspects to maximise energy capture and meet load limits.

WP4 Design of mechanical structure & analysis

WP Leader: NTNU 
Other contributor(s): TUD  
The overall aim of this work package is to establish a complete, economic design of X-ROTOR. To this effect a structural design will be developed that integrates and supports the various requirements/components developed in WP2, WP3 and WP5 for the rotor, the control system and power-take off system in a safe and economic manner

WP5 Power take off and conversion system design

WP Leader: UoS 
Other contributor(s): Cener 
In this work package generators, power converters and their interfacing/control will be designed. In addition, the design of the secondary rotors will be adjusted to ensure that their characteristics match those of the electrical generators.

WP6 Cost of Energy Reduction Analysis

WP Leader: UoS 
Other contributor(s): UCC 
This WP will (i) model the operation & maintenance costs for X-ROTOR; (ii) model the cost of energy for the X-ROTOR; (iii) model the cost of energy for existing offshore wind turbines; and (iv) compare the cost of energy from objectives 2-3 to determine the CoE saving from the X-ROTOR concept

WP7 Environmental and Socio-Economic Impact

WP Leader: UCC 
Other contributor(s):  UoS, TU
This WP aims to assess and mitigate the social, economic and environmental impact of the X-Rotor concept. It is concerned with assessing and maximising the social, economic and environmental benefit of the XROTOR concept. This WP is an integral part of the project which will interact with other WP and key stakeholder groups in an iterative manner to shape an optimise the development process.

WP8 Industry Ratification and Further Development Roadmap

WP Leader: UoS 
Other contributor(s): TUD, UCC, Cener, GE, NTNU 
This work package will ensure all work carried out in WP1–7 meets a standard acceptable to industry and that assumptions made and feasibility evaluations are realistic. It will also work to ensure cohesion and maintain flow of information between WPs. A roadmap for further development of the X-ROTOR will also be prepared within this WP.

WP9 - Communication, dissemination

WP Leader: UCC 
Other contributor(s): UoS, TUD, CENER, NTNU 
This work-package deals with the procedures and techniques for the dissemination and communication of the project results, although other dissemination activities are included within WP8. The main objective is to effectively disseminate the results and increased understanding gained during the project. Moreover, this work package aims to maximise the impact of the project into society by means of an effective communication plan.


The X-ROTOR project will develop a highly innovative wind turbine design to directly target cost of energy reduction and scalability of wind turbines.

Work Plan

The X-ROTOR project runs for three years from January 2021, during which time, the concept will be developed through a holistic consideration of technical, cost, environmental and socio-economic impact aspects.


A project led by University of Strathclyde (UK) working with Delft University of Technology (NL), University College Cork (IE), Fundacion Cener  (ES), GE Renovables España (ES), and the Norwegian University of Science and Technology (NO)
