Ground Run-up Enclosures

Ground Run-up Facility Ground Run up Enclosure Ground Running Up Enclosure Ground Run-up Enclosure A SOLUTION FOR ENGINE GROUND RUN-UP NOISE

As the aviation industry has evolved, so too has the responsibility that airports have in being considerate community members. Communities near airports expect solutions to reduce the acoustic impacts of all operations, including ground run-up noise, created by aircraft. Maintenance run-ups typically create a greater noise nuisance than actual takeoffs and are often scheduled at night. This can result in noise complaints from the community and creates a serious public relations problem for airport officials. Fortunately, a GRE that is both acoustically and aerodynamically functional can address this issue.

BDI pioneered a cost-effective, technologically-advanced solution for ground run-up noise attenuation. We offer ground run-up enclosure (GRE) facilities that use patented components, proven designs, and have a spotless track record of successful installations. BDI’s philosophy is to balance project technical requirements with practical solutions.

Every GRE project requires a customized approach due to the unique conditions and circumstances that exist at each airport and surrounding community. BDI understands the complicated dynamics of a GRE project, which often includes many diverse parties, each with a different background and agenda. In addition to being the turnkey supplier, BDI’s role involves facilitating teamwork among the owners, facility users, consultants, regulatory agencies, and the local community. BDI has learned through experience what is necessary to elicit cooperation from all involved.

BDI’s run-up management system (RMS) adds information technology that greatly benefits users, owners and stakeholders.

TYPICAL BDI CONFIGURATIONS

BDI’s 3-Sided GRE has been the industry standard since 1996.

BDI’s standard GRE configurations are 3-sided or 4-sided facilities. The configuration depends on the required acoustic performance and aerodynamic considerations. For a complimentary analysis of how BDI technology can mitigate ground run-up noise problems, please contact us. BDI’s philosophy is based on providing our customers with the highest quality products and services that match BDI’s international reputation of performance and value earned over the last 60 years.

BDI’s 4-Sided GRE provides 360 degrees of noise attenuation.

THE AERODYNAMIC CHALLENGE

Running aircraft engines at high power settings while stationary can be challenging for various reasons:

  • Aircraft engines require smooth and turbulence-free air at the nacelle (inlet).
  • Modern aircraft are efficient and powerful, and the latest turbofan engines use high bypass ratios with larger fan diameters. This places the engines closer to the ground compared to previous-generation aircraft, which can create significant aerodynamic challenges.
  • Ground running aircraft in a GRE is more complicated than open-field conditions due to the fixed facility orientation, tall acoustic walls, and atmospheric conditions.

BDI’S AERODYNAMIC SOLUTION

Through the use of scale model testing, computational fluid dynamics (CFD), and field evaluation of more than 30 completed facilities, BDI continually provides innovative aerodynamic features that maximize facility usability. BDI’s patented designs and the outstanding performance of our facilities is one reason BDI builds the best GREs in the market.

NOISE ATTENUATING TECHNOLOGY

Engine run-ups typically occur at night, precisely when communities near airports are most sensitive to noise. With over 30 successful GRE facilities constructed to date, BDI understands that the primary reason to build a GRE is the acoustic benefits such a facility brings to airports and communities. BDI works with all stakeholders to develop a solution that, first and foremost, meets the project acoustic requirements. BDI’s Noise Blotter acoustic panels are designed specifically for the low frequency sounds created by aircraft engines and provide a much higher degree of noise attenuation than standard acoustic panels.
