Low-Speed Measurements of Rolling and Yawing Stability Derivatives of a 60 Degree Delta-Wing Model
Year: 1954
Type: article
Abstract: An investigation has been.made in the Langley free-flight tunnel to determine the law-speed rolling and yawfng stability derivatives of a 600 delta-wing model from 0 ' to 300 angle of attack.The derivatives were measured by the free-to-damp oscillation technique and by the steady-roll technique.The results of the investigation showed that the damping-inyaw parameter Grdetermined from free-to-damp oscillation tests was much larger in the high angle-of-attack range than the value of t h e damping-in-yaw parameter Gr determined for a similar model by the yawing-flow technique.The damping-in-roll parameter 12% decreased with increasing angle of attack and became approximately zero at an angle of attack of 3 0 ' .
