However, so we don't get centre of gravity or aerodynamic centre movements aft of the blade elastic axis ( which can introduce undesirable aerodynamic and inertial couplings ), then the tip must be configured with an area shift forward.
2.
Forward of the 1.5 D body extension, the geometry of the AGARD-C model is identical to that of the AGARD-B . Also, the position of the moments reduction point ( the aerodynamic centre ) is the same as on AGARD-B.
3.
The wings were rectangular in plan, mounted without aerodynamically balanced in the usual way but were connected to each other by three vertical rods which halfway up were hinged to the trailing edge of a narrower and shorter horizontal surface which rotated about an axis well behind its aerodynamic centre.
