"Madec" Si&Si Deflector Jet Blast Deflector Fence
Our fences against jet blasts protects not only vehicles and equipment from the stream of gases expelled by engines’ planes but also people. It also acts as acoustic screen and so it diminishes the impact of the plane’s dangerous noises on human hearing system.
“Madec” Si&Si deflector, reduces blast speed up to 90% and redirects upwards (nearly vertical). It also accomplishes ICAO (International Civil Aviation Organization) recommendation on minimum visibility through it. So that users can see and prevent
every possible excessive approach of the planes itself or other vehicles.
Our blast fences are designed, built and proved for:
• Wide-body aircraft types.
• Jet blasts speeds ranging between 50 and 60 m/s and temperatures up to 60°C.
Data regarding planes and also location and conditions behind every deflector are taken into consideration in its design, manufacture and assembly in order to provide the adequate degree of protection.
Tolmien and Göertler models are considered in determining the jet blasts characteristics, because both have been widely confirmed for the jet engines gases unload on a flat and rough surface, as it is a non-paved soil.
Upwards deviation of the horizontal jet blast coming out from a plane engine interferes the part of the flow that eventually passes above the fence and so mobilizing air masses that deviates cool down and decelerate the jet blast.
The fence effect depends closely of its distance to the engines and the power regime of these ones.
The aerodynamical behaviour of the deflector has been analysed in the Test Bench for Aeronautic Engines Development of the Spanish National Institute of Aeronautical Techniques (INTA). It was proved that jet blasts fulfils the stable and laminar flow requirements once they have passed the deflector mesh cell.

Asturias is located on the north-west Iberian peninsula, at the very heart of Green Spain. It is home to over a million inhabitants and is one of the 17 Autonomous Communities that form the state of Spain. It is a member of the European Union and a member state of the Euro Zone.
The climate in Asturias is Atlantic, with mild temperatures throughout the year. With 354 km of coastline, it naturally lends itself to being an ideal place to visit and live. The region is characterised by its extraordinary natural beauty, with breath-taking beaches and vast wooded areas, with a third of the land declared a natural protected area.
All these components make Asturias a “Natural Paradise”. Asturias also offers an excellent quality of life, with bustling cultural activity, a rich artistic heritage and ideal conditions for playing a whole host of sports.
There are three branches of activity that produce around 87 % of the turnover in Asturias and 82 % of industrial employment:
- Metal Industry
- Extractive industries, energy and water
- Food and agricultural industry
