Once it reaches the fully twisted state the spar will have cleared the clearance holes in the hub shaft enough that it can then fold back on the pin For example, the web of a spar may be a plate or a truss as shown in Figure 9. The engines drive the aircraft through the propellers by means of torque, which is reacted at the attachment points on the front spar. The decisive advantage of this construction method is that there is no bonding material inside the wing spar itself and consequently none in the main shearforce area. Thus, the wing design begins with one known variable (S), and considering all design requirements, other fifteen wing parameters are obtained. In reality, the shape of the surface between neighboring ribs, and the leading and trailing edge boxes is also controlled by the mechanical properties of the cover material. analysis is also performed for wing design purposes.
