Abstract
A device is provided for containing blades of rotating turbomachinery comprising a high-strength ring supported in radial spacial relationship over the blade tips by means of a stationary support structure. The ring is supported in such a manner that it is capable of spinning with respect to the support structure when acted upon by a predetermined blade force.
Claims14
A device for containing blades of rotating turbomachinery comprising:
- a high-strength ring for surrounding in radial spacial relationship a stage of rotatable turbomachinery blades;
- and
- support means disposed generally outwardly of said ring for supporting said ring in a manner such that when the rotating blades contact said ring blade rotational energy is absorbed by imparting spin to said ring with respect to said support means.
A device for containing blades of rotating turbomachinery comprising a high-strength ring supported in radial spacial relationship over a stage of rotatable turbomachinery blades by support means, and wherein said ring is capable of spinning with respect to said support means when acted upon by a predetermined blade force.
A device for containing blades of rotating turbomachinery comprising a high-strength ring carried in radial spacial relationship over a stage of rotatable turbomachinery blades by support means which permit said ring to spin when contacted by the rotating blades such that the blade rotational energy is absorbed primarily by said ring instead of said support means.
In a method of containing blades or rotating turbomachinery, the steps of:
- surrounding in radial spacial relationship a stage of rotatable turbomachinery blades with a high-strength ring;
- and
- supporting said ring in such a manner that said ring is free to rotate when acted upon by a predetermined blade force, thereby absorbing blade rotational energy.
