NOTE: Standard Frame Blanket Width

•The standard agreed upon by Airbus and TIS = 280 mm•The standard Frame Geometry:

•Height = 80mm

•Inboard Flange = 20mm

•Outboard Flange = 15mm

NOTE: Frame Heights are not

constant throughout the A/C

SEE Slide 24 for modelling

Instructions in these areas.

Step 17 – Frame Blanket Profile Creation

17. Create Profile of Frame Blanket• Create a Plane using “Normal to Curve” with Frame edge

and a point in Intersection (created in Step 16)• Create Sketch on This Plane (Sketch.1)• Use ‘Projected 3D Elements’ From Intersection• Isolate (Rt-Click→Object)• Fix

For Frames With Variable Geometry(Ex: F Frame 91/82 – Cargo in Aft)

Follow Steps 1-1516.v Create intersections between Frame & SurfacesBoth Stringer and/or Floor Surfaces (remember )• For Top & Bottom (Like Step 16)• If Frame does not entirely intersect the Stringer P Surface:

• Use Extrapolate to extend P Surface

Step 16.v Continued…

For Floor Split an extra step is requireda. Create Intersect using Floor MG as

in step 16v.b. Create a Plane Normal to Curve at

Floor level using a point from this Intersection on Cabin side of Frame.

c. Create another Intersect with this Plane and Frame Body
