Paper Title
Cost-Benefit Analysis Of Two Similar Warm Standby Satellite Systems Subject To Failure Of Fbtp Due To: (A) Gripping At One Of The Seal Locations And Seizure Of Rotor And (B) Rupture Of Turbine Casing Caused Probably Due To Excessive Pressure Rise And Thermal Stresses

Abstract
In this paper we have taken failure of Fuel Booster Turbo Pump (FBTP) due to: (a) gripping at one of the seal locations and seizure of rotor and (b) rupture of turbine casing caused probably due to excessive pressure rise and thermal stresses. When the main operative unit fails then warm standby system becomes operative. Failure of FBTP due to gripping at one of the seal locations and seizure of rotor cannot occur simultaneously in both the units. After failure the unit undergoes repair facility of Type- I or Type- II by ordinary repairman, Type III or Type IV by multispecialty repairman immediately when failure of FBTP due to: (a) gripping at one of the seal locations and seizure of rotor and (b) rupture of turbine casing caused probably due to excessive pressure rise and thermal stresses. The repair is done on the basis of first fail first repaired.
