ANALYSIS OF VIT1D-TTJIUNEL STABILITY AND CONTROL
TESTS IN TERMS OF FLYING QUALITIES OF
By Gerald G.. Kayten.
The analysis of results of wind-tunnel stability
and control tests of powered airplane models in terms of
the flying qualities of full-scale airplanes is advocated.
In order to indicate the topics upon which comments are
considered desirable in the report of a wind-tunnel
stability and control investigation and to demonstrate
the nature of the suggested analysis, the present NACA
flying-qualities requirements are discussed in relation
to wind-tunnel tests. General procedures for the esti-
mation of flying qualities from wind-tunnel tests are
At the laboratories of the National Advisory Committee
for Aeronautics and at laboratories maintained by various
universities and independent agencies, wind-tunnel tests
are often made to investigate the stability and control
characteristics of particular airplane designs. Upon
these tests are based., to a large degree, the decisions
regarding changes and improvements necessary in order to
make the final product a satisfactory airplane. Unfortu-
nately, however, the test results are in most cases not
presented in such a manner as to permit their immediate
use in making these decisions; instead, the wind-tunnel
data are usually presented in coefficient form in a
voluminous series of curves and tables.
As judged in flight testing or service, the flying
qualities of an airplane involve not dimensionless coeffi-
cients, but dimensional quantities - forces, velocities,
