Cranfield University

University of Cranfield Logo 250px
‌‌Cranfield University has been at the forefront of aerospace research and technology for over 60 years, offering a practical and holistic approach right across the business of flying. The University, at its main campus in Cranfield, Bedfordshire, and at its campus in Shrivenham near Swindon, has been active in rotorcraft research and technology development throughout this period, contributing to many of the major national and international research programmes over the years. Partners have included national government research agencies and defence departments, helicopter manufacturers and operators.

‌The School of Aerospace, Transport Systems and Manufacturing  is home to a wide base of expertise and experience in rotorcraft experimental and computational aeromechanics, flight performance and operational analysis. On the experimental aerodynamics side, Cranfield is a member of the National Wind Tunnel Test Facility, offering three large scale low national strategic wind tunnels. In addition is has well equipped transonic wind tunnels that have been employed on rotor tip section studies involving shock wave interactions. Computational aero-prediction has also been at the heart of Cranfield rotorcraft activities for the past 20 years, with URANS, LES and DES solvers being applied to rotor and full helicopter performance simulation. The Rolls-Royce UTC in Performance Engineering at Cranfield has been at the forefront of rotorcraft performance analysis, environmental impact and mission optimisation, making major contributions on the EU Clean Sky Programme. Other research activities include rotorcraft flight dynamics and handling, structural crashworthiness, helicopter safety and accident investigation, rotorcraft reliability and helicopter gearbox lubrication and condition sensing.

Cranfield staff have participated in a number of recent national and international rotorcraft research collaborations including GOAHEAD (Generation of Advanced Helicopter Experimental Aerodynamic Database for CFD Code Validation), FRIENDCOPTER (Integration of Technologies in Support of a Passenger and Environmentally Friendly Helicopter), CLEANSKY Technology Evaluator, and the UK Defence Applied Research Programme (DARP).


University of Glasgow

University of Glasgow logo 250pxThe University of Glasgow has been involved with a variety of helicopter and rotorcraft research activities since the 1980s. This has included experimental aerodynamics, some computational fluid dynamics, gyroplane flight testing, and flight ‌dynamics and simulation. The efforts have been conducted using a range of high-quality experimental and computational facilities including large-scale wind tunnel facilities equipped with comprehensive instrumentation and dynamic rigs, an experimental autogyro aircraft, and simulation facilities. Wind tunnel experimentation for helicopter related phenomena includes dynamic stall, blade-vortex interaction, vortex-ring state, rotor wake in ground effect and brown-out. The techniques used include surface pressure measurement and PIV, and there is some experience of rotor operation and design.

Glasgow has featured in a number of inter-institutional projects as a key member of the rotorcraft DARP, as part of previous and current EU projects GOAHEAD and CleanSky, and has been a member of GARTEUR networks. Much of this work has been achieved through close links with government bodies and industry, and funding through EPSRC, for example. For many years the Department of Aerospace Engineering ran an annual technical meeting which brought the UK academic and industrial communities together. Glasgow's aerodynamics and fundamental fluid mechanics work has been published in a wide range of journals including AIAA journals, AHS Journal, Journal of Fluid Mechanics, Experiments in Fluids, Aeronautical Journal. Academic staff with a current interest in helicopter/ rotorcraft related applications including aerodynamics and flight mechanics include Dr.R.B. Green, Dr. D.G. Thomson, Dr. E.A. Gillies.


University of Leicester

ukvln University of Leicester Logo 250pxLeicester's main contribution to the VLN is in control system design. The Control Systems Research Group has been active for the last 20 years in the design and testing of control systems for rotorcraft. The Group has received several EPSRC Grants to enable this research and has also been part of the DARP, REACT and RTVP projects in conjunction with AgustaWestland and several other Universities. The Group is particularly well-known for its development of multivariable primary flight controllers, based on H-infinity optimisation, for various rotorcraft. Some of these controllers were implemented, in-flight on the NRC's Bell 205 fly-by-wire helicopter where it was demonstrated that H-infinity approaches to controller design enabled an attractive alternative design route for helicopter control laws. During the DARP project, similar controllers were developed for the AW101 helicopter. More recently, as part of the REACT and RTVP projects, its efforts have focused on the development of actuator control schemes for novel actuators and vibration management systems for vibration reduction.

The Group has used control strategies based on NDI (non-linear dynamic inversion) for the control of highly non-linear semiactive lag dampers and a variety of linear control methodologies for the control of active trailing edge flaps. In addition, vibration management systems have been developed using tools from multi variable system identification and, again, H-infinity optimal control theory. The Group is also beginning to expand its capabilities in rotorcraft UAV's with a number of computation/simulation based studies. Leicester is represented in the VLN by Dr. M. Turner and Dr. R. Morales who are responsible for all the current rotorcraft research in the Control Group.


University of Liverpool

University of Liverpool logo 250px‌The School of Engineering at The University of Liverpool has been re-located to a purpose-build new facility to house research and teaching activities. A substantial university investment (£17M) combined with a £15M allocation from the Science Research Investment Fund resulted in a re-structuring of Engineering at Liverpool; including the refurbishment of research laboratories and the creation of an "Active Learning Laboratory" for undergraduate and postgraduate students (http://www.liv.ac.uk/erp/.).

The Department has attracted more than £20M of research income over the last three years and is a key player in several national and international projects. The Department is also home to a dedicated 1024-strong Beowulf cluster and two full-motion simulators used for rotorcraft research. A fully equipped dynamics testing laboratory is also operational with several testing facilities for vibration and modal identification of structures.

1. Flight dynamics modelling and simulation.

2. Systems engineering of conventional and autonomous systems.

3. Training and education.

Muretex’s rotorcraft flight dynamics capability draws upon work performed in support of MOD-funded research programmes concerned with helicopter flight dynamics, handling qualities and control, operation of rotorcraft to and from ships and integration of autonomous aircraft within a network-centric environment.‌

Muretex has deployed these capabilities in the production of helicopter training systems, an important aspect of which has been the transfer of developments in the research domain into the application domain. Furthermore, as a provider of subject matter expertise to those procuring training systems, Muretex has extensive knowledge of both the supplier and customer sides of training system procurement and the practical assessment of modelling developments and their impact on training fidelity and effectiveness.

Muretex also has expertise in the development and deployment of autonomous airborne systems which has the potential to be a timely offering to the VLN. Experience in this area has been developed over close to two decades of technical leadership in the development of autonomous systems concepts, their integration within existing air systems and their evaluation within large-scale live and synthetic environment trials.

Most recently, Muretex has supported the development of an experimental rotor testing facility, using a systems engineering approach to capture stakeholder requirements, interpreting published rotor test results to guide rig sizing calculations and demonstrating a proof-of-concept desktop simulation to support operational concepts.
