Ulmann An investigation to determine the loagitudinal and lateral stbility characteristics of an airplane conffgurztion ha* a trzpezoidal wing with e modified hexagonel eirfoil section and a crucfformtail with 5O semimgle vedge section has been carried out in the Langley 9- by 9- inch Mac

The wing has e tragezoidal plan forn with a hexagonal section tht has been modi- fied by rounding the leadling edge to t 1-percent-chord radius and blunting the treiling

6、edge to a 2-percent-chord thickness. The wing hzs a maxirnum thickness of 4 percent, and the quarter-chord. Une is swest 290. The tails have a trapezoidal plan form, a 5 semiangle wedge section, and a cor?figuration installed in the T-langley 9- by 9-inch Mech number 4 blov- down jet is presented in

8、nd the settling-chamber stag- nation pressure was held at approxinately 186 parnds per sqwe inch absolute. These conditions correspond approxinately to a Reynolds number of 2.7 x 106 based on the wing mean aero6ynamic chord. The tests were run at humidities below 5 x pounds of water vapor per pmd of

9、 dry air, which is believed to be low enough to eliminate water-condensation effects. The test-section static temperature and pressure did not reach the point where liquefaction of air would take place. Data were obtained for angles of attack from Oo up to Eo at angles of sideslip fron Oo up to 8O.

10、CISIN OF DATA Tne probable uncertainties in the test data due to the accuracy limi- tations of the balance and recording equipment and the ability of the system to reseat data points are listed in the following table: (The accuracy of the rolling-moment coefficients is low relative to the Itiaxirmun

11、 rolling moment encountered. Tds low accuracy occurred because rolling- moment gages were added to an existing balance which was not originally designed to measure rolling monent.)
