Experimental identification of whirl flutter characteristics in a small-scale rotor rig

| Description | The research is part of the MENTOR project with other university partners from the UK Vertical Lift Network. The project aims at developing new simulation, analysis, and experimental methods for novel rotorcraft configurations. The work conducted at the University of Bristol explored the development of novel methods in three main research streams, namely: multibody dynamic modelling, experimental vibration monitoring and assessment for rotor rigs, and Implementation of CFD Methods on Highly Parallel Architectures. The main findings of the project are: 1- The use of the Udwadia-Kalaba approach for modelling multibody systems for rotorcraft applications seems to be a promising approach that can provide an efficient framework for developing aeroelastic simulation tools for novel rotorcraft configuration. 2- 2D and 3D multibody dynamics tools based on MATLAB were developed. 3- We were able to simulate whirl flutter in a wind tunnel setup using a propeller test rig that we have developed. This rig helped to develop experimental prediction and monitoring techniques for this project. 4- Codes for monitoring the dynamics of rotating systems were developed. 5- Conducted experimental modal analysis tests for the national tiltrotor rig at the University of Glasgow. 6- Conducted experimental modal analysis tests for a new set of blades of the national tiltrotor rig. 7- Initial Implementation of Finite Volume Methods on Highly Parallel Architectures using GPU's. Two software have already been developed. 8- Eight publications. 9- One journal paper is under review and drafts are being prepared for three other journal papers. |
| Exploitation Route | The outcome of this work can be used for better prediction and analysis of a several industrial dynamics and aerodynamics problems that required efficient and accurate (both low and high fidelity) simulation capabilities. The applications can range from aerospace, automotive to renewable energy, etc. |

| Title | Focal, A modern Fortran abstraction layer for OpenCL |
| Description | Focal, A modern Fortran abstraction layer for OpenCL https://github.com/LKedward/focal#focal Focal is a module library which wraps calls to the openCL runtime API (using clfortran) with a higher abstraction level appropriate to the Fortran language. The goal of Focal is to provide a concise and accessible Fortran interface to the OpenCL API while retaining the full functionality thereof. This is desirable in Fortran which as a language provides a higher level of abstraction than C; importantly this allows scientists and engineers to focus on their domain specific problem rather than details of low-level implementation. |

| Geographic Reach | National |
| Primary Audience | Postgraduate students |
| Results and Impact | This is the second training event of the UK Vertical Lift Network (www.ukvln.net) for the 2019 - 20 20 session. It aims to bring together the UK research community on vertical lift and is inspired by similar events taking place outside the UK. The event will cover introductory concepts of rotorcraft dynamics and control and is suited for early stage researchers at MSc or PhD level. The event spans 2 days and includes lectures and laboratory exercises. The list of topics includes: • Rotor dynamics and helicopter vibration (Dr Branislav Titurus, University of Bristol) • Rotor stability and aeroelasticity (Dr Djamel Rezgui, University of Bristol) • Advanced control for rotorcraft (Dr Rafael Morales, University of Leicester) • Actuation Technologies (Dr Jon du Bois, University of Bath) |
