The second picture here shows the airframe when both wings are in-flight, where the V-shape of the airframe basically links them together. You can see the turbulent boundary layers roll up under the wing's leading edges in both scenarios. The wing itself, of course, is connected to the airframe by its various attachments.
Professional wind tunnel testing showed that the first problem can be easily solved. The mounting feet of the canopy can be eliminated, leaving only a simple hinge and a rigid nylon collar. This effectively eliminates the frame, strengthening the canopy and leaving the pilot as little more than a passenger (except for the horizontal parabola effect).
While in the L-4 Recovery Stabilization Model, the wing is a simple cantilever. In the L-5 Recovery Stabilization Model, the wing is much more complex. The wing tip is connected to the wing root by a short tube and a 6 degree of freedom hinge. Once again, the entire wing assembly can be removed (except for the horizontal: static pressure due to the angle of attack can cause the wing-tip irons to push out at an angle in flight).
The entire wing is kite-shaped, with the apex of the kite left high and the foot of the kite firmly anchored to the ground. The wing itself curves out at some angle about 5 degrees above the horizontal. This will aid in smooth, gradual transitions between mid and upper levels of drag. As with any aircraft, the strength of the wing is proportional to the drag it generates. It may be much higher at high angles of attack, but the pilot is unlikely to use these maneuvers in any event. Instead, the pilot will focus on flying for level flight, and on increasing airspeed sufficiently that the increase in angle of attack (and the front and rear fuselage will rotate outward toward the wings) will not cause the airplane to stall.
The fuselage is contained by a tube that contains the pilot and the aircraft systems; this tube is connected to the wings by a common upper airframe. If the pilot is strapped into the back seat of the cabin, this can mean that the area left behind by the pilot is nearly empty. d2c66b5586
