Combinations of an NACA 23012 tapered wing and a circular fuselage having a wedge-shaped rear were tested in the NACA 7- by 10-foot wind tunnel to determine the effect of wing-fuselage interference on the lateral-stability of wing-fuselage interference on the lateral-stability characteristics. The model configurations represented a high-wing, a mid-wing, and a low-wing monoplane. For each configuration, tests were made with a partial-span split flap neutral and deflected 60 degrees and with and without a vertical tail. Tests of the fuselage alone and of the fuselage with the vertical tail were also made.

Four N.A.C.A. 23012 wings were tested at several angles in the N.A.C.A. 7- by 10-foot wind tunnel. All the wings have rounded tips and, in plan form, one is rectangular and the others are tapered 3:1 with various amounts of sweep. Each wing was tested with two amounts of dihedral and with partial-span split flaps.

An N.A.C.A. 23012 rectangular wing with rounded tips was tested in combination with a fuselage of circular cross section at several angles of yaw in the N.A.C.A. 7- by 10-foot wind tunnel. The model was tested as a high-wing, a midwing, and a low-wing monoplane; for each wing location, tests were made with two amounts of dihedral and with partial-span split flaps. For each combination of wing and fuselage, tests were made with and without a fin. Sample charts of the coefficients of rolling moment, yawing moment, and lateral force are given for some of the combinations tested. THe rate of change in the coefficients with angle of yaw is given for stability calculation.

Model combinations of an NACA 23012 tapered wing and a circular fuselage were tested in the NACA 7- by 10-foot wind tunnel to determine the effect of longitudinal wing position on the change in lateral stability due to interference. The aerodynamic center of the wing was located at approximately 80, 130, and 180 percent of the mean locations, the model was tested as a high-wing, a mid-wing, and a low-wing monoplane. For each conbination, testes were made with a partial-span split flap neutral and deflected 60 degrees and with and without a vertical tail. The rearmost low-wing combination was tested with and without a fillet.

Tests were made in the LMAL 7- by 10-foot tunnel to determine the effect of a horizontal tail on the lateral stability characteristics of a high-wing, a mid-wing, and a low-wing monoplane. The model combinations consisted of a circular fuselage, an NACA 23012 tapered wing, and an NACA 0009 horizontal tail surface. Each wing-fuselage combination was tested with a partial-span split flap neutral and deflected 60 degrees and with and without a single vertical tail. Tests were also made of the fuselage with and without the tail surfaces.

Download Determination of the Stability and Control Characteristics of Airplanes from Tests of Powered Models Book in PDF, ePub and Kindle
A technique of testing wind-tunnel powered models has been developed as a result of experience gained in the investigation of the static longitudinal and lateral stability and control characteristics of several powered models in the NACA 7- by 10-foot wind tunnel. As an important part of this technique, a minimum program of the tests considered necessary to specify satisfactorily the static stability and control characteristics for present-day airplanes has been tentatively established.

Download Determination of Lateral Stability Characteristics from Free-flight Model Tests, with Experimental Results on the Effects of Wing Vertical Position and Dihedral at Transonic Speeds Book in PDF, ePub and Kindle
A test and analysis method is presented for determining airplane lateral stability characteristics, including aerodynamic derivatives, from flight tests of scale models. The method of analysis utilizes the rotating time-vector concept and also a quasi-static approach. Data are presented at transonic speeds for three swept-wing rocket-propelled models differing only in vertical position and dihedral of the wing. The method proved to be adequate for delineating the major effects of the geometric variations on the aerodynamic lateral stability derivatives. The effects of Reynolds number on the linearity of the static stability data for an unswept wing configuration are illustrated.
