Shroud assembly for gas turbine engine

A shroud assembly for a gas turbine engine, the shroud assembly comprising:

• a hanger, the hanger comprising a forward hanger arm, a rear hanger arm axially spaced from the forward hanger arm, and a hanger body extending between the forward hanger arm and the rear hanger arm;
• a shroud, the shroud comprising a forward surface, a rear surface axially spaced from the forward surface, an inner surface extending between the forward surface and the rear surface, and an outer surface extending between the forward surface and the rear surface and radially spaced from the inner surface, the shroud connected to the hanger;
• a support member positioned axially forward of the forward hanger arm, the support member comprising a radially outer portion connected to the forward hanger arm and a radially inner portion axially spaced from the shroud such that a gap is defined between the radially inner portion and an axially adjacent surface of the shroud;
• and
• a mechanical fastener connecting the radially outer portion and the forward hanger arm.
