Dublin Airport – Jet Blast DeflectorsFebruary 9, 2022 | Aviation
We specified two complementary types of taxi and breakaway thrust jet blast deflectors, providing protection from the harmful effects of aircraft jet blast to perimeter roadways, infrastructure and apron parking stands. Our 4.0m high Curved Solid Barriers [CSB] and 4.0m high Vertical Mesh Barriers [VMB] were installed in key areas of the taxiway system supporting the new North Runway.
In conjunction with AKS Ward, our civil design partners, a full scheme of foundation design and jet blast barrier hardware was detailed for the four barrier locations. On site installation was completed by Roadbridge FCC directly. The overall scheme was delivered with effective collaboration and efficiency, combined with a high quality Jet Blast Protection safety solution, on time and budget.
IAC Acoustics had previously delivered a jet blast protection safety project at Dublin Airport – a temporary barrier specified during runway construction works. It was designed for conversion to permanent use and was re-configured for implementation into the new fixed barrier installation. Positive outcomes of this modular engineering approach to our jet blast deflector systems include; project cost benefit, flexible safety infrastructure, reduced lead times and environmental impact.
The Curved Solid Barrier provides a full blockage protection system, deflecting the aircraft jet wake up and away from the protection zone. The CSB has been utilised in locations parallel to the runway to provide protection as taxiing aircraft turn to either enter or exit the main runway.
The Vertical Mesh Barrier has been utilised where maintaining a visual line of site is beneficial – typically access routes for airport service vehicles at runway crossing points, and within the parking apron areas. The use of the VMB provides a visually transparent protection system, enhancing airfield safety and minimising risk. A further benefit of the VMB system are the simple and effective angle and height step change requirements needed to support changes in elevation and direction, without compromising protection.
The combination of product types for this project provided the best balance of requirements between a cost effective solution and protection and safety needs on the airfield. IAC Acoustics Jet Blast Deflector systems support compliance with airfield best practice via CAA Airside Safety Management, CAP642 (ICAO Annex 14)
Where possible, blast screens should be provided to protect buildings, installations and vehicle and staff areas that are vulnerable to blast
Mark Newton, IAC Acoustics Aviation Business Manager summarised the project;
We are delighted to be delivering another Jet Blast Deflector safety project for Dublin Airport. We have enjoyed collaborating on the project solution with and for the various stakeholders – ensuring airfield safety and project effectiveness is the prime focus for our Aviation team. Being able to utilise some of our existing infrastructure to create a new solution was particularly rewarding – we look forward to working together on future projects.
