TLDR
In a turbofan engine, a fan is designed for reduced damage during a blade-out condition wherein the fan blade airfoil is disposed asymmetrically on the platform and includes a forwardly displaced leading edge.Abstract:
In a turbofan engine a fan designed for reduced damage during a blade-out condition wherein the fan blade airfoil is disposed asymmetrically on the platform and includes a forwardly displaced leading edge. The platform is configured to make early contact with a following airfoil upon blade-out.read more

Blade containment structure
TL;DR: The inner honeycomb region is deep enough to position the septum out of the orbit of the fan tips in an engine made unbalanced by loss of one or more fan blades as mentioned in this paper.
Patent
Blade shank cooling arrangement
TL;DR: In this paper, an arrangement for cooling turbine blade shanks for gas turbines is presented, wherein a perforated chamber is arranged to cause a cooling fluid to impinge with a predetermined pattern upon inner wall surfaces of a shank portion of a turbine blade and/or the outer walls of adjacent turbine shanks.
Patent
Blade containment device
TL;DR: In this article, a high-strength ring supported in radial spacial relationship over the blade tips by means of a stationary support structure is provided for containing blades of rotating turbomachinery, which is capable of spinning with respect to the support structure when acting upon a predetermined blade force.
