Abstract
A turbine missile shield is formed by a series of substantially semi-cylindrical, concentric stainless steel shells joined and spaced apart by longitudinal and transverse spreader beams. The longitudinal peripheries of the shells are joined to form mounting rims with bolt holes formed therein to enable mounting on a turbine pedestal or operating floor.
Claims3
An energy-absorbing turbine missile shield for containing any broken pieces of rotatable parts of a turbine thrown outwardly through a turbine casing with substantial kinetic energy comprising:
- (a) at least two rigid spaced concentric curved shells enclosing the turbine casing and formed of ductile stainless steel deformable plastically as well as elastically under impact of said broken turbine pieces to absorb their kinetic energy without resulting in complete penetration through both of said shells;
- (b) a plurality of longitudinal spreader beams of ductile metal connecting and spacing apart the two shells;
- and
- (c) a pair of opposed mounting rims formed by opposed edges of at least one of said shells to permit mechanical attachment of the shield with respect to a fixed operating floor.
