“…While zircon sand was used as the stucco material for the first slurry coat, mullite grits were used for stuccoing 'after' the subsequent coats to achieve desired shell thickness, strength and refractoriness.After each stucco coating, the coated wax cluster was dried for 2-3 h in a controlled atmosphere room where temperature was maintained at 20±5°C and relative humidity at 15±5%. After the final stucco coat, the coated cluster was subjected to deep drying for about 20 h in the above mentioned room 11 .…”

Turbo-fan gas turbine engines, or simply turbo-fan engines (STFEs), are used for powering both manned aircrafts and unmanned air vehicles (UAVs). The high pressure turbine section of such engines use Ni-base superalloy cast rotor blades because of their good mechanical properties at high operating temperatures. The present paper provides the technical/technological details of the various aspects associated with development and manufacturing of high pressure turbine blades (HPTBs) for utilization in an indigenously-developed small turbo-fan engine. Vacuum investment casting process has been adopted for realization of the above equiaxed components using a Ni-base superalloy
