24TH INTERNATIONAL CONGRESS OF THE AERONAUTICAL SCIENCES ANALYSIS AND RIG TEST IN EMB170 FLAP MECHANISM DEVELOPMENT Tsutomu Yoshida, Yoshirou Mizusaki and Toshimi Taki Kawasaki Heavy Industries, Ltd., Aerospace Company Keywords: kinematics, high lift device, rig test Abstract Kawasaki Heavy Industries, Ltd. developed flap mechanism of Embraer 170. Kinematic analysis and rig test for the flap mechanism were performed in order to reduce development risk. Basic operation tests were performed successfully before the first flight of the aircraft. 1 Introduction Kawasaki is participating the development of Embraer 170/190 commercial jet family as a partner and responsible for development of the flap mechanism and structure. The flap of Embraer 170 is a double-slotted Fig.1. Embraer 170 and Flap type to realize high lift coefficient at landing (see figure 1). The flap mechanism is a 2 Flap Mechanism sophisticated design with track rails, rollers and rods. Two track supports are attached to the trailing edge of the wing box structure to support each During the development phase of the flap flap, the inboard flap and the outboard flap. mechanism, Kawasaki performed internal load Each track has two main track rails. A main analysis considering gaps, friction, flap panel
