Jet Blast Deflector – The AMB jet deflector system uses the same grid configuration as the VMB installed in the “A” frame structure. In application, the deflector is designed to “lean” into the aircraft’s jet path at an angle of approximately 30°.
Exhaust fumes from a high-energy jet engine can cause injury and damage. Rocket blasts have been known to uproot trees, shatter windows, overturn cars and trucks, level poorly built structures, and injure people. Other aircraft, especially light ones, were blown away and damaged by exhaust gases.[2]

Hurricane-force air currents moving at speeds up to 100 knots (190 km/h; 120 mph) have been measured over 60 m behind the largest jet aircraft. The two General Electric GE90 engines on the Boeing 777 together produce about 200,000 pounds (900,000 N) of thrust [1] – a level of force high enough to kill [2].

To avoid these problems, airflow deflectors direct the airflow in a safe direction, often upwards. If you have custom requirements, we can provide a complete project overview with CFD simulations to evaluate barrier effects for your specific site installation and environment.
We can also offer an independent study of the impact of radar on steel barriers in specific locations. Whether it is permanently installed or designed as a mobile solution; Whether they are made of steel or fiberglass reinforced plastic, the principle of operation of jet blower deflectors remains the same in all designs to purposefully deflect airflow to create protected areas.
We keep your airport safe with customized Blast-Ex® high performance jet deflectors. They are available both fixed and mobile to provide maximum flexibility and area security. In addition, transparency provides good visibility over the airport and all maneuvering areas.
Jet blast deflectors range in complexity from fixed concrete, metal or fiberglass barriers to heavy panels that are raised and lowered by hydraulic arms and actively cooled. Anti-blast deflectors can be used to protect helicopters and airplanes from propeller water.
Curved Solid Barrier [Csb]
At airports and jet engine service centers, jet engine deflectors can be combined with sound absorbing walls to create a ground enclosure where an aircraft jet engine can be tested safely and more quietly at full thrust.
Available in both fixed and mobile versions, our jet deflectors come in two pieces for easy assembly and storage. There are several standard types available in our program, but since each airport has its own unique characteristics, our deflectors can be custom-made to provide the correct jet height, strength and deflection for each individual application.
The AMB deflector is also available as a modular mobile system. The barrier structure is mounted on a specially designed concrete base for forklift loading. This allows for flexible use by quickly and easily deploying blast barriers at temporary locations.
The CSB jet deflector system can be used for high drag and liftoff applications where the use of an aerodynamically and visually permeable barrier is undesirable. The difference in performance between the two power ratings is the distance between the base frames.

Custom Solutions
A jet deflector is often referred to simply as a “jet deflector”, but the term has other meanings. In artillery technology, the term “explosion deflector” refers to a device that protects the calculation of the gun from an explosion from the muzzle of the gun.
In pistols, a “jet deflector” is another name for a muzzle brake that directs the muzzle blast sideways and upwards to prevent it from exiting the muzzle during automatic fire. Our deflectors are hot dip galvanized during the manufacturing process.
Powder coating is applied immediately after galvanizing. Thus, the usual need for sweeping (roughening the steel surface) is eliminated. This double-sided coating process also creates a superior and durable color finish. Most deflectors direct the jet stream upward, but hot gases can instead be directed downward and directed below deck to be vented harmlessly away from the side of the aircraft carrier.
This solution has two advantages: the upper surface of the deflector does not overheat and can serve as a deck immediately after takeoff, and the air above the deflector is not dangerous for aircraft flying through hot gases.[7]
Foundations And Installation Services
At railings at the end of the runway and at special airport maintenance areas where high power engine testing may be carried out, high power/takeoff thrust should be considered. In all other areas of the airport, such as terminals and aircraft stands, the need for taxiing and lift-off should be taken into account in addition to protecting service roads.
Especially if aircraft operate in close proximity to buildings, vehicles, fixed or mobile facilities or personnel. The vertical design profile minimizes footprint and maximizes space utilization, which is important in many busy operating airports. The safety and protection of people and buildings is enhanced by a direct view through the mesh deflector.
In addition, this jet deflector is commonly used as a protection system for service roads and helipad perimeters. For our Blast-Ex® Jet Blast deflectors, we have added one more step before the manufacturing stage. We simulate air flow digitally.
Through this visualization, we can directly see how effective our design is as we envisioned, or we need to add some minor adjustments to further improve efficiency. Typically, a 4 m high barrier can be fitted with steel support frames with a standard 2.5 m spacing (the spacing of the end sections is reduced to 1.25 m).
Functional Principle
When used for higher performance requirements, this distance between frames is reduced to 0.834 m (ends are reduced to 0.417 m). All other aspects of the design remain the same. The increased power deflector is designed for off-road engines.
IAC Aviation has developed a range of deflectors to meet most of the requirements for personnel and infrastructure protection. We understand that sometimes custom requests are needed. Our extensive experience in the design and engineering of surge protection devices will help you meet your specific requirements.

We can provide security solutions to meet security needs for extreme temperatures, unique shapes, or even powered moving barriers. Watch our video of the moving curved stationary barrier at Dublin Airport. This practice is interesting not only for new projects, but also for customers with existing jet deflectors.
We provide relevant research as a service product. Checking the effectiveness of existing deflectors and observing the degree of their deviation helps to make a decision to upgrade. {{#each product.specData:i}} {{name}}: {{value}} {{#i!=(product.specData.length-1)}} {{/end}} {{/each} } A jet blast deflector (JBD) or shroud is a safety device that redirects high-energy jet engine exhaust gases to prevent damage and injury.
Angled Fibreglass Barrier [Afb]
The structure must be strong enough to withstand heat and high-speed air currents, as well as dust and debris carried by turbulent air.[1] Without a deflector, jet blast can be hazardous to people, equipment, and other aircraft.[2]
In the years since the first installation, Blastwall has built airport retaining walls in many challenging locations and conditions. We invite you to view photo galleries of five amazing installations and learn about the radar invisible steel and fiberglass versions of our product, as well as our new movable/reconfigurable wall options.
Our design team compared common aircraft flow profiles from major manufacturers to create a solution that would suit most yaw applications worldwide. This indicator made it possible to model the total estimated jet wave velocity of 45 m/s.
To complete the reference calculations, the average aircraft proximity was limited to 10 m from the tail of the aircraft to the obstacle. All of our fixed flow deflectors require the installation of a suitable concrete foundation.
Vertical Mesh Barrier [Vmb]
To ensure foundations are suitable for barrier loads, IAC Aviation offers two alternative structural solutions. We can provide detailed calculations of structural reaction forces and moments so that others can design appropriate foundations. Alternatively, we offer a complete foundation design service in which the necessary foundations will be detailed for a particular application so that others can install them.
In order to properly design a foundation, the customer must declare the condition of the ground, or IAC may commission a ground survey. This provides a correct estimate of the bearing capacity of the soil. The specification and use of jet deflectors is a vital element in the success of any airport and aerodrome.
The security and protection of assets with jet barriers is paramount to risk management; The propeller and jet blast from a parked or maneuvering aircraft not only generates high speed winds, but can also result in foreign object damage (FOD).
Thus, Blast-Ex® Jet Blast deflectors protect people, equipment and facilities in or around an airport by reliably diverting and slowing down the flow. This type of barrier is particularly suited where barrier requirements may interfere with airport ILS systems and radars, or where the barrier is required to be fragile, such as at runway endpoints, etc., to prevent undue damage to aircraft in the event

precipitation. The safety of personnel, equipment and facilities on and off the airport is the primary responsibility of every operator. In addition, improving operational efficiency and maximizing asset utilization are vital to achieving economic performance. Airports have a legal obligation to protect people, vehicles, aircraft and buildings from dangerous high speed aircraft collisions.
Our deflectors are made of hot dip galvanized steel or fiberglass reinforced plastic and can be painted if required. Over seventy-five years of experience at Ruhrtaler Stahl- und Behälterbau GmbH & Co. KG and over eighty successful airport projects around the world always guarantee the high quality of our Blast-Ex® Jet Blast deflectors.
For over 70 years, IAC Aviation has been the world leader in jet blast protection solutions, delivering cutting-edge engineering design innovation combined with superior performance, quality, manufacturing and installation. This facilitates the specification of jet nozzle deflector protection systems worldwide.
The fiberglass nozzle deflector provides all the protection expected of a sloped barrier system with the added benefit of being brittle. This minimizes the potential cost associated with impact risk and has the added benefit of being free of corrosion, including fiberglass structural supports and bolts.
The steep points are designed to make the collision as efficient as possible in order to minimize the financial impact of any collision. In collaboration with our global partners (Blastwall Ltd), IAC Aviation offers an original and patented fiberglass deflector system designed to solve the problems associated with placing metal barriers near airport systems such as radar or Instrument Landing System [ILS].
Its performance has been tested and qualified by NAV Canada to operate without interference to electronic transmissions on the ground and in flight. In addition, it is also certified for installation by the US Federal Aviation Administration.
Using our 4m high solid curved barriers [CSB] and 4m high vertical mesh barriers [VMB], we have been able to provide two complementary types of jet deflectors to provide protection against the most damaging effects of wind gusts on roadways, airport infrastructure and parking areas.
The VMB jet deflector system is designed in accordance with Boeing recommendations. It is capable of withstanding loads due to wind conditions and jet velocities distributed by taxiing aircraft in accordance with BS6399-2.

After a jet engine has been overhauled or parts have been replaced, it is normal to run the engine at full power to check it.[8] Rural airports rarely provide more than a remote part of the airfield for full thrust engine testing, but urban airports surrounded by residential areas often require engine testing to be conducted on a ground runway to reduce engine noise.
