Patent ID: 7971827

Claim:
A bird collision prevention device securable to a cowling of a turbine engine of an aircraft, comprising: a. a plurality of circular interior support members each having a sequentially decreasing diameter concentrically disposed along an axis, and wherein each circular interior support member has a diameter at least 20 percent and up to 50 percent smaller than a prior circular interior support member, and wherein the plurality of circular interior support members are sequentially oriented along the axis; b. a plurality of outer ribs, wherein each outer rib is welded tangentially to the plurality of circular interior support members disposed sequentially along the axis forming a conical shape mesh body with a tapered end; and c. a plurality of attaching means, wherein the mesh body is secured to the cowling of the turbine engine using the attaching means and enabling the tapered end to extend away from the turbine engine and prevent at least one foreign object from entering the turbine engine; the bird collision prevention device further comprising a first piston and a second piston each connected on a first piston end to the cowling and on a second piston end to the circular interior support member with the largest diameter; and a connection disposed between the first and second pistons having a first connection end engaging the cowling and a second connection end engaging the circular interior support member with the largest diameter.
