The invention discloses a controllable
strake wing / canard wing pitching angle
movement system of an
airplane wind tunnel test model. The controllable
strake wing / canard wing pitching angle
movement system comprises a headpiece and frame component, an
airplane model shafting
vertical axis, left and right connecting shafts, left and right
strake wings / canard wings as well as rotary shafts thereof, left and right bearings, left and right bearing seats, left and right reversing
bevel gear pairs, left and right motor installation bases, left and right motors and a coder, left and right main wings, a computer and left and right motor drivers, wherein the right strake wing / canard wing is fixed with the right strake wing / canard wing rotary shaft, the right strake wing / canard wing rotary shaft is connected with the right end of the right connecting shaft, the left end of the right connecting shaft is connected with lower gears of the right reversing
bevel gear pair, the same connecting mode is adopted at the left side; the left strake wing / canard wing rotary shaft axis and the right strake wing / canard wing rotary shaft axis are symmetrically arranged along longitudinal symmetrical surfaces of the
airplane model shafting
vertical axis. The controllable strake wing / canard wing pitching angle
movement system can be used for realizing controllable
yaw motion of the strake wing / canard wing pitching angle, and changing the mode of regulating the strake wing / canard wing pitching angle through a
fixed angle plate in a
static mode in the conventional wind tunnel test.
