Abstract
A method of fabricating a bonded cascade assembly of a thrust reverser for an aircraft nacelle. The method may include inserting individual turning vanes between spaced apart elongated stiffeners at an aft end thereof and sliding the turning vanes toward a front frame piece attached to or integrally formed with forward ends of the elongated stiffeners. The elongated stiffeners may have inner and outer flanges for trapping and limiting radial movement of the turning vanes. The method may further include bonding the turning vanes to the structural frame with a structural adhesive and attaching a closeout cap to the aft ends of each of the elongated stiffeners.
Claims20
A method of fabricating a bonded cascade assembly of a cascade thrust reverser of an aircraft engine nacelle, the method comprising:
- sliding a plurality of turning vanes into a structural frame, wherein the structural frame comprises a plurality of elongated stiffeners having forward and aft ends, and a frame piece attached to or integrally formed with the forward or aft ends of the elongated stiffeners, wherein sliding the plurality of turning vanes into the structural frame comprises inserting the turning vanes between the elongated stiffeners at the aft or forward ends opposite of the frame piece and sliding the turning vanes in a direction toward the frame piece;
- bonding the turning vanes to the structural frame with a structural adhesive;
- and
- attaching a closeout cap to each of the elongated stiffeners at the aft or forward ends opposite of the frame piece.
A method of fabricating a bonded cascade assembly of a cascade thrust reverser of an aircraft engine nacelle, wherein the bonded cascade assembly comprises a structural frame, a plurality of turning vanes, and a closeout cap, wherein the structural frame comprises a plurality of elongated stiffeners with forward and aft ends and a front frame piece integrally-formed with the forward ends of the elongated stiffeners, the method comprising:
- inserting the turning vanes between the elongated stiffeners at the aft ends;
- sliding the turning vanes in a direction from the aft ends of the elongated stiffeners toward the front frame piece, wherein the elongated stiffeners each have a geometry configured for cooperatively preventing or limiting radial movement of the turning vanes slid therebetween;
- bonding the turning vanes to the structural frame with a structural adhesive;
- and
- attaching the closeout cap to the aft ends of each of the elongated stiffeners.
