ARA Leads TRUflow Clean Sky 2 Project

Aircraft Research Association Ltd (ARA) is pleased to confirm it is leading a 3-year project with partners Rolls-Royce, RUAG AG, and the University of Manchester to explore complex flow physics associated with aero engine thrust reverser units integrated within Ultra-High Bypass Ratio (UHBR) engines that will power the next generation of large passenger aircraft.

Thrust Reverser Unit flow visualisation project (TRUflow) is part of the European Union’s Clean Sky 2 Large Passenger Aircraft (LPA) Innovative Aircraft Development Platform (IADP). The project plans to develop novel experimental measurement techniques for the visualisation and evaluation of the reverse flow interactions with fan blades for the next generation of Ultra-High Bypass Ratio (UHBR) engines, and to create effective and efficient numerical methodologies for the evaluation of TRU cascades.

For the experimental investigations ARA has designed and built a high specification scaled fan for static demonstration testing at ARA. This test will prove the ground breaking internal optical measurement systems being developed specifically for TRUflow. The partners are designing, reviewing and testing a TRU wind tunnel model for tests in RUAG in 2021.

TRUflow is one of the first projects to generate significantly greater understanding into the complex flow physics surrounding the interaction of thrust reverser units with the fan and the effect of air flow cascades.

Mr Paul Hutchings, Chief Executive Officer stated “ARA is pleased to be leading this project with our partners. This new insight will influence future UHBR engine efficiencies that will lead to substantial reductions in fuel consumption and emissions with future large passenger aircraft”.

Aircraft Research Association Ltd is a leading independent aeronautical testing and research business located at Bedford, UK providing complementary services and solutions to international aerospace and defence clients to support their aerodynamic concept development. Capabilities include Transonic Wind Tunnel testing and related facilities, the design and manufacture of high specification instrumented scale models, as well as computational analysis and consultancy.

Rolls-Royce Holdings PLC is a United Kingdom-based engineering company. The Company is focused on power and propulsion systems. Its segments include Civil Aerospace, which is engaged in the development, manufacture, marketing and sales of commercial aero engines and aftermarket services; Defence Aerospace, which is engaged in the development, manufacture, marketing and sales of military aero engines and aftermarket services, and caters to sectors, including combat aircraft, trainer aircraft and helicopters; Power Systems, which is engaged in the development, manufacture, marketing and sales of reciprocating engines and power systems.

RUAG AG is a Swiss engineering company. As a future-oriented technology partner of the Swiss Armed Forces, RUAG focuses on life cycle management, operation and availability of military systems. All business activities are therefore strongly geared to the procurement programmes of the main customer, the Swiss Army. The extensive product and service portfolio of RUAG includes customized subsystems and components for tracked and wheeled vehicles, fighter jets, military helicopters and anti-aircraft systems. We also provide reliable information and communications solutions, not to mention comprehensive maintenance and repair services.

The University of Manchester in England is the largest single-site university in the UK and is a public research university formed in 2004 by the merger of the University of Manchester Institute of Science and Technology and the Victoria University of Manchester.
