High Quality Jet Blast Deflectorsmade in Germany

We support your airfields safety with customized, highly efficient Blast‑Ex® Jet Blast Deflectors. These are available both stationary or mobile to provide maximum flexibility and zonal security. In addition, the transparency ensures good visibility over the airfield and all manoeuvering areas.

Our jet blast deflectors are made of either hot-dip galvanized steel or fibre glass reinforced plastic and can be color coated if required. Over seventy-five years of experience of Ruhrtaler Stahl- und Behälterbau GmbH & Co. KG and more than eighty successful projects on airports around the world grant high quality of our Blast‑Ex® Jet Blast Deflectors at any give time.

Jet Blast Deflectors

Jet Blast Deflectors

Blast‑Ex® Jet Blast Deflectors provide safety for vehicles, pedestrians, airport facilities, other buildings and nearby public roads that may be subjected to jet blast from aircraft maneuvering on runways, taxiways and tarmacs.

Our jet blast deflectors – available both stationary or mobile – are bipartite, enabling an easy assembly and storage. There are several standard types available in our program, but since each airport has its unique characteristic, our jet blast deflectors can be custom designed to ensure proper height, strength and jet blast deflection in respect of every individual case.

Functional principle

Prop- and jet blast of parking or maneuvering aircrafts not only cause high velocity winds, but might also cause Foreign Object Damage (FOD). Blast-Ex® Jet Blast Deflectors therefore protect people, facilities and objects on or around the airport by reliably deflecting and slowing down jet blast.

Our jet blast deflectors can withstand blasts at speeds of up to 300 m/s and, at the same time, temperatures of up to 500 °C.

Design and material

Design and material

Blast‑Ex® jet blast deflectors are manufactured at our facility in Germany from structural, stainless and heat-resistant steels and, if required (to protect ILS/Localizer antennas and other NAV/COM equipment), from glass fiber reinforced plastics.

Our jet blast deflectors are hot-dip galvanized during the production process. The powder coating is applied directly after galvanizing. The usual need for sweeping (roughing up the surface of the steel) is thus not necessary. This duplex coating process also produces an excellent and durable color finish.

At the beginning of every construction, there is a thought, an idea and some key figures. Followed by sketches, drawings and schemes. Once this development has been completed, the production can start.

In the case of our Blast‑Ex® Jet Blast Deflectors we are adding one additional step before the production phase. We digitally simulate the airflow. Thanks to this visualization, we can directly see if our design is as efficient as intended, or if we need to add some minor adjustments in order to raise efficiency even more.

A computer based model can show the force and the behavior of jet blast, in front and behind our deflectors. It shows where pressure cushions are building up and where we need to optimize our design, in order to avoid them. We are able to visualize the degree of the jet blast deflection before our deflectors are built.

This practice is not only interesting for new projects, but also it is interesting for customers with existing jet blast deflectors. We provide a corresponding study as a service product. Checking the efficiency of your existing deflectors and making their degree of deflection visible, helps with decision finding regarding modernization.
