What is Determination of the stability and control characteristics of a tailless all-wing airplane model with sweepback in the Langley free-flight tunnel about?

An investigation to determine the power-off stability and control characteristics of a tailless all-wing airplane model with sweepback has been made in the Langley free-flight tunnel. The results of the free-flight tunnel tests were correlated with results from force tests made at high Reynolds numbers in order to estimate the flying characteristics of the full-scale airplane. The investigation consisted of force and flight tests of a 4.3-foot-span dynamic model. The effects of flap deflection, center-of-gravity location, and addition of vertical-tail area were determined. The following conclusions were drawn from the results of the investigation: The full-sale airplane will undergo a serious reduction in stick-fixed longitudinal stability at high life coefficients unless early wing-tip stalling is eliminated. The directional stability of an all-wing airplane without vertical tail surfaces will be undesirably low. The effective dihedral of an airplane of this type should be kept low. An elevon and rudder control system similar to that used on this design should provide sufficient control
