Everything you see on these pictures does not exist anymore. All this equipment, stands, engines etc. were scrapped in short terms. The buildings will probably be demolished too. The object is guarded and it was hard to get into, in the end the photographer had to run from the dogs and climb the fence to escape...
Here they used to test engines.
The control panel had already been disassembled by someone.
Everywhere on the walls are posters with images of engines and instructions.
The stand for testing engines used to be here but was scrapped and taken away.
It's the filtrating system under the ceiling: the ventilation had to cope with a big amount of exhaust because nearby were many dwelling houses. The walls are rather thick, they had to muffle the sounds of the jet engines.
