Refinement and analysis of concept

Wing structure layout

• The box beam also conveniently acts as integral tankage for the fuel
and access panels are required for inspection purposes.
• For moderate to high aspect ratio wings the box beam should be
continuous across the whole span.
• Large cutouts for such items as landing gear stowage should be
outside its boundaries.
• When the powerplant is buried within the fuselage and the wing is of
relatively low aspect ratio, it is often necessary to use several spanwise
spars and to pass the bending loads round the fuselage by means of a
series of ring frames to which the spars are connected.
