SABRE is a large, multi-partner H2020 research project funded by the European Union. The project team includes the University of Bristol, CIRA, DLR, TU Delft, TU Munich, and Swansea University. It is being coordinated by Dr. Benjamin Woods (Bristol) and has a budget of €6M over 3.5 years.
Investigating six morphing concepts that allow for shape adaptation and real-time optimisation of key rotor design parameters, with the potential to apply multiple concepts on a single blade to minimise emissions.
• Supporting the long-term health of the EU rotorcraft industry
• Improved aerodynamic efficiency of the rotor over a wide range of flight conditions - reducing fuel burn, CO2 and NOx emissions by 5-10%
• Lower fuel costs = more competitive products
• The technologies and analysis tools developed will be useful in other industries, including commercial airliners and wind turbines.
SABRE is developing ground-breaking new helicopter blade morphing technologies which will reduce helicopter fuel burn, CO2, NOx and noise emissions by 5-10%. We will do this by tackling one of the most fundamental limitations on helicopter performance: the need for rotor blades to have a single fixed geometry which is inherently a compromise between widely different operating conditions. SABRE envisions shape adaptive blades continuously changing their shape to optimise performance in all conditions. Morphing technologies are being developed that can change the twist, camber, chord, and dynamic behaviour of helicopter blades. In parallel, analysis work combines comprehensive, mixed-fidelity rotor models with morphing mechanism and emissions models to create the most detailed and comprehensive model of its type. ... [more]
