Cell 3 West (649): Then And Now

Cell 3 West appears to be well represented within the photographic record. Not only was it photogenic (with its striking front section and impressive superstructure), but the variety of testing (from gas turbines stress tests through to helicopter fuselage icing tests) meant the photographer was often required.

Cell 3 West allowed a multitude of differently configured tests to take place, although the testing of gas turbines under various weather conditions was its primary function. In this shot, two engineers position a Rolls-Royce RB211 engine for testing.

The original photographer was crouched in the south western corner of the cell. Luckily I also took a shot from exactly the same position.

I believe the original photographer took this elevated view of the northern area of Cell 3 West from the external stairs of Number 10 Exhauster. In doing so, he captured the end of Cell 3 West with its connecting pipes in place, the massive air cooler, and the two tanks (which each held 500 tonnes of aqueous ammonia).

When I visited the site in 2007, the connecting pipes had been removed, and could be found scattered around the area south of Number 10 Exhauster. Unfortunately I never took a shot from the external stairs (as Id have been seen by the employees working in Sigma), but I had this ground level shot for comparison.

Taken at a lower elevation, but almost the same view. The connecting pipe is missing.

This first shot shows another gas turbine installed in Cell 3 West. However, its an interesting picture as the front dome of the cell has been removed allowing the original photographer to capture the entire width of the cell and the end of the walkways.

The second colour shot shows a different turbine being installed, but taken from within the cell itself.

Fast forward to 2007, and the dome was fixed in place (although I did at times wonder how easy it would be to decouple it and slide it back on its tracks). So, my comparison shot was taken where the man was standing in the original photograph.

Cell 3 West was designed to accommodate ever larger gas turbines and even helicopter fuselages. To allow these large pieces of equipment to be installed, the front dome could be removed. Then, with the equipment in place, the front dome was latched back in place, and connecting pieces of pipe connected the end of the cell to the air cooler.

The original shot clearly shows the cell ready for testing, with all the constituent pieces in place. My shot shows an empty cell with the front dome in-situ, but the connecting pieces of pipe have been removed (presumably after the last test).

A slightly different view. The missing sections of pipe could be found to the south of Number 10 Exhauster.

The first photograph shows how Pyestock engineers were able to fit the entire fuselage of a Sea King helicopter into Cell 3 West and the second shows an RB211 turbine. Not only does this show the cell's flexibility, but also illustrates how it was the only cell which could accommodate objects as large as a fuselage.

The best comparison shot I could find is this angled shot of Cell 3 West with the front dome still attached.

The control room was housed in a brick building situated to the north of the test cell itself and was packed with engineers and technicians when the tests were run.

Luckily I took a similar shot looking across the modernised control room. Some of the controls had survived the years; others had been updated. Unlike most of the control rooms at Pyestock, the control room for Cell 3 West had been partially stripped and vandalised.

These two shots again show how the cell's front could be removed allowing ever larger turbines and scaled helicopter fuselages to be inserted.

The shot of the V.2500 engine suggests temporary scaffolding was erected around the turbine during the test. My comparison shot is completely barren by comparision.
