STATIC STABILITY AND CONTROL OF CANARD CONFIGURATIONS
AT MACK NUMBERS FROM 0. 70 TO 2.22 - LATERAL-
DIRECTIONAL CHARACTERISTICS OF A
TRIANGULAR WING AND CANARD
By Victor L. Peterson and Gene P. Menees
Results of an investigation of the static lateral-directional
stability characteristics of a canard airplane configuration are presented
without analysis for the Mach number range of 0.70 to 2.22. The configu-
ration consisted of a triangular wing and triangular canard both having
an aspect ratio of 2.0, a low aspect ratio vertical tail, and a fineness
ratio 12.5 Sears-Haack body. The hinge line of the canard was in the
extended wing chord plane, 1.21 wing mean aerodynamic chords ahead of the
reference center of moments. The ratio of the area of the exposed canard
panels to the total area of the wing was 6.9 percent. Data are presented
for various combinations of the canard, body, wing, and vertical tail.
These data were obtained at angles of attack from -6o to +180 at 00 and +5o
sideslip angles and at angles of attack of approximately Oo and +100 at
sideslip angles from -80 to +10. The canard was set at angles from 00
The possible gains that can be realized at supersonic speeds by the
use of canards rather than tail aft controls include reduced trim drag
and increased maneuverability. Because of the increased interest in these
arrangements, an extensive research program aimed at determining the static
longitudinal, lateral,' and directional characteristics of a number of
canard configurations has been undertaken at the NACA Laboratories. This
report is one of a series pertaining to the program and presents without
analysis the static lateral-directional stability characteristics from the
Ames Laboratory for one complete configuration and its component parts.
The configuration consisted of a triangular wing and triangular canard
