(54) HIGH-SPEED WING WITH EXTENSION PIECE
(57) Abstract:
FIELD: aeronautical engineering.
SUBSTANCE: swept or straight wing of subsonic
aircraft is provided with front and rear extension
pieces forming profile as spatial system on basis of
middle surface. Profile of wing extension pieces is
formed by linear sections of inserts in nose and tail
parts of wing which are located in points of extremum
of functions describing the coordinates of upper and
lower surfaces of wing. Length of linear sections of
inserts is equal to length of extension pieces.
EFFECT: increased operational flying speeds;
improved lifting properties of wing.
