GT11N2 new / GT-Support Strength evaluation

Thermal Block is fixed on the Baseframe vertically by the four supports-struts, and horizontally by the Key below Turbine and by the King Pin below Compressor (Fig. 1). At an operation a Thermal Block (with Combustion) is on GT-Support, coupled with Exhaust Diffusers, and there is also a spring support below Exhaust Housing. In that case the Anchorage fixe the whole package (Thermal Block on GT-Support) to the foundation, while GT-Support consists of two separate parts. Turbine and Compressor's side parts. At transportation a Thermal Block (without Combustion) is installed on GT-Support and fixed by fixations to the ground (vehicle), close to positions for installation of anchor bolts. In that case a GT-Support is one structure. Longitudinal beam carriers connect turbine and compressor side parts. At lifting, a thermal block (without combustion) is installed on GT-Support.All structure hangs on four vertical ropes (two at turbine side support and two at lifting lugs on compressor casing). In that case a GT-Support is also one structure. Longitudinal beam carriers connect turbine side part and compressor side parts. The maximum loading acts on GT-Support and to Anchorage are evaluated in previous calculations. The aim of this analyze is to perform a mechanical integrity check of GT-Support and Anchorage.
