Abstract

A double-slotted Fowler flap in transport aircraft has more complexities in kinematic synthesis and design. The present research work presents a combination of six-bar mechanism, four-bar mechanism and a double-slotted mechanism configured for deployment of a Fowler flap arrangement. The mechanism is synthesized for cruise, take-off and landing conditions. A novel procedure for dimensional synthesis and optimization of the mechanism is developed for synchronizing flap and aft-flap positions. The complete synthesis, optimization procedures and parametric analysis are coded into MATLAB program. The results of the synthesis procedure are verified with 2D planar kinematic models and 3D solid models using SolidWorks. Also the novel kinematic synthesis procedure is validated by developing a prototype model of the mechanism using 3D printing technology.
