Sometimes it is necessary to have quick access to jet blast deflectors, for only a limited time and without the need of purchasing a complete set. Especially, when maintenance on the apron is due, and workers and equipment at temporary work sites need to be protected from jet blast.

Jet blast is a phenomenon, which inevitably occurs in connection with jet or turbofan-driven aircraft. Simplified: They move because a mass of air is sucked into the intake, compressed by a high ratio, and then with the help of ignited fuel is accelerated and pushed out again.

Building an efficient jet blast deflector is not as easy as it might look. Of course, anybody can spend a lot of money, use too much material, waste time in the construction, or set-up process and then finally end up with a product which does not fit the needs of the airport and its managers.
