3、L AND DIRECTIONAL STABILITY OF A TRAPEZOIDAL-WING AIRM MODEL AT MACH NUMBERS OF 1.41 AND 2.01“ By Ross B. Robinson SUMMARY An investigation has been conducted to determine the effects of vertical location of the wing and horizontal tail on the static lateral and directional stability at various comb
4、ined angles of attack and side- slip for a supersonic airplane configuration at Mach numbers of 1.41 and 2.01. The wing had a trapezoidal plan form with an aspect ratio of 3.00, a taper ratio of 0.25, and 4-percent-thick circular-arc sec- tions. The horizontal tail was also a trapezoid with an aspec
5、t ratio of 4, a taper ratio of 0.6, and NACA 65006 airfoil sections. The configurations investigated were a high-wing, a midwing, and a low-wing arrangement, in combination with horizontal-tail positions varying from a location 0.208 wing semispan below to 0.556 semispan above the body center line.
6、Tests were made both with and without the horizontal tail, vertical tail, and wing. The investigation was con- ducted in the Langley 4- by des- ignated the low tail position) to two positions on the vertical tail (0.382b/2 and 0.556b/2; designated the high and tip tail positions, respectively). Prov
7、ision was made for varying the incidence angle of the horizontal tail. The wing position could be varied to provide high-, mid-, or low- wing configurations. The angles of incidence and dihedral were zero for all wing positions. Force and moment measurements were made through the use of a six- compo
8、nent internal strain-gage balance. Base pressures were measured by a tube placed just inside the base of the model. The model was mounted on a rotary sting to permit testing at combined angles of attack and side slip. TESTS, CORRECTIONS, AND ACCURACY The conditions for the tests were: Mach number .

10、25 F or less so that no significant condensation effects were encountered in the test section. Tests were made through combined angles of attack and sideslip to about ljo at M = 1.41 and to about 28 at M = 2.01. The angles of attack and sideslip were corrected for deflection of the balance and sting
11、 under load. Base pressures were measured, and the axial force measured by .the balance was adjusted to a base pressure equal to the free-stream static pressure. The Mach number variation in the test section was less than tO.015 and the variation of the flow angles in vertical and horizontal planes
