Rolls Royce Welland No. 183 as recovered from Duce's scrapyard in Cambridge.
Peter Grieve working on the initial refurbishment at The Rebel Air Museum Earls Colne in 1994.
The turbine, with the compressor in the background, during reburbishment in 1994.
On the move to Carlisle in 1995
In Solway Aviation Museum before ownership passed to Terry Jones.
In Terry Jones' workshop in Carlisle, the start of dismantling.
Partially dismantled on a part built working frame.
The engine and working frame mounted on its special road trailer.
Ready for dismantling.
The gearcase as removed, shows rust stain from water ingress.
Shows light corrosion and minimal wear in gearcase.
Oil metering pumps under the gear case directing oil to the main bearings.
Another view of the oil metering pumps.
The front main bearing and two gearcase shaft bearings.
The inlet to the front side of the compressor.
Half of the front section of the compressor case removed. Shows the impeller and the diffuser.
Showing the damage the diffuser caused by water ingress corroding the magnesium compressor case.
Impeller with front shaft removed showing bronze bolt which secures the turbine and impeller shafts together.
Combustion chamber assembly showing the exit from the combustion chambers.
The nozzle guide vanes. The nylon ties are to hold the turbine while the securing bolt is tightened.
Combustion chamber assembly, from the other compressor side.
Shows splits and dents in some of the combustion chambers.
Shows welded repairs to the magnesium compressor casing.
Compressor case removed showing rear bearing and combustion chamber entries.
Close up of the rear bearing.
The components of the rear bearing, shows the oils and air supply connections. The air supply blows the oil into the bearing.
The refurbished rear bearing housing, showing the bearing coolling air inlets and outlets.
The two halves of the front section of the compressor case.
Shows corrosion of one section of the compressor case.
Close up of the corrosion, caused by the ingress of rain water over a long period.
The same section cleaned up and given a thin coat of epoxy paint.
The impeller as removed from the engine.
The impeller and turbine, after having been cleaned up, on a simple balancing rig.
No signs of any burning on the turbine blades, note the fir tree roots.
The engine number stamped on the front half of the compressor case adjacnet to the join.
The engine number stamped on the top edge of the same component.
The engine number stamped on the gearcase, The "S" is a hang over from Rover's involvement.
Shows damage to the sidewalls of the diffuser.
The two halves of the diffuser assembly, the fronf half having been repaired.
Shows the split caused by the freezing of rain water that found its way into oil sump.
The split repaired.
Shows one half of the inlet guide vanes. Many of the engine's major components are in two halves to enable assembly about the impeller and turbine.
Another view of the inlet guide vane. Rover modified the impeller so that the turbine and the impeller could be assembled at a later stage of the erection of the engine.
Turbine guide vanes, prior to the turbine being fitted. The white painted ducts feed cooling air to the back of the turbine disc.
The gearcase prior to reassembly. The casting having been cleaned up and repaired.
