The latter, in turn, caused warping and fractures of the turbine inlet nozzles.

The failure of the inlet nozzle was due to liquid metal embrittlement of the train B aluminium cold box by elemental mercury.

An even circulation takes place with the helps of the inlet nozzles provided at the inlet of tubes which creates the differential pressure adequate to cover the variations occurring at fluctuating loads or uneven firing conditions.

Hot gas from the gas generator was routed to the turbine inlet manifold which distributed the gas to the inlet nozzles where it was expanded and directed at a high velocity into the first stage turbine wheel.

The SES has two advantages over a hovercraft for open sea operation: it is more resistant to slipping sideways when acted on by air or sea and, and it can use water jets for propulsion since the inlet nozzles are always covered by water.
