GROUND RUN-UP ENCLOSURES
The Ground Run-up Enclosure (GRE) is a combined acoustic and jet blast protection structure that allows aircraft engine testing either for first engine runs after manufacture or post maintenance activities for MRO’s or airlines.
The dual function provides acoustic benefits of up to 20dB(A) by providing noise absorption and blocking the transmission of noise directly to noise sensitive locations while incorporating jet blast protection built into the rear wall structure.
Beyond the need to provide acoustic and blast protection, the GRE is required to provide an aerodynamically stable testing environment for all aircraft in as wide a range of meteorological conditions as possible, this is what ultimately determines the success of a facility design.
The IAC GRE has been developed through an in depth knowledge of aerodynamics and a history of providing full performance test facilities to all the major engine manufacturers.
Starting from scratch IAC were determined to let nothing divert from achieving the best aerodynamic and acoustic performance combination for our modern state of the art facilities and used high performance computational fluid dynamics software and modelling techniques to iteratively refine the shape and provide the ultimate in GRE performance.
The end result is a GRE that provides superior acoustic and aerodynamic performance over the widest possible range of ambient conditions.
KEY FEATURES OF THE IAC GRE
- Fully scalable design for code C (III), D (IV), E (V) & F (VI) aircraft
IAC provide the complete turnkey service for the GRE and can design the required civil works and foundations, provide lighting maps, full electrical systems for ground power, monitoring and recording systems, airfield obstruction lighting, special signage, emergency exit doors and can supply this service globally for any airport and any customer via our manufacturing capabilities at our global sites from the UK to Australia. No other company can provide the level of experience in both acoustics and aerodynamics to ensure the GRE meets ALL the required performance targets.
