VIII, the triplane was grounded not because of spar failure, but because of the disintegration of the secondary structure- wing ribs etc- whilst the spars remained intact. Make one mistake and the wing gets ruined! The half-spar alone was over $4k. IT was now evident that some other effect would have to be taken into account to obtain a more exact agreement between theory and experiment, and it was fairly obvious that the non‐rigidity of the wing root attachments was the chief cause of the discrepancy. The spar inspection and repair procedure does not have to be performed by a mechanic holding an inspection authorization, as any appropriately certificated mechanic may perform this function. One or more sections can be transported to a designated location and off-loaded into water from an available transport vessel.

Abstract — Decreasing of system's vibrations is an important issue for all mechanical structures like an aircraft wing where it is subjected to many types of disturbances. Add in the fact that even in a multi-spar wing one (the "main" spar) usually takes the vast majority of the weight - for example in the P-47 and P-51's rear spar were mostly just to provide tension for the ailerons and flaps, not for wing rigidity, and were much smaller than the main spar. For instance, the limiting criterion for both multi rib and multi spar concepts is skin buckling. The FrSky Vantac AR+ Wing has white EPP molded wing and fuselage, plus a built-in carbon fiber spar which makes the structure durable, rigid and lightweight. In the composite material wing structure of the present invention, a vent line extending in the span-wise direction can be formed in the spar itself of the composite material multi-spar structure.
