This project serves to develop a new flap design concept entitled "seamless contact trailing edge flap (SCTEF)" and analyze it on a regional airliner model. It covers a wide range of engineering work processes and due to the realistic nature and wide scope of the project, it can be made comparable to real life engineering projects, which engineers deal with in their course of work. CAD models are developed in CATIA V5 R19 software.
Computational Fluid Dynamics (CFD) study will be conducted to explore the effect of new flap concept entitled "seamless contact trailing edge flap (SCTEF)" on lift and drag of the regional airliner during takeoff. In this work ANSYS FLUENT 14.5 was used as Computational Fluid Dynamics (CFD) software. The working condition of simulation was considers at the aircraft takeoff just before the rotation speed 'V1'. Two configurations (i.e. wing with deflected flap & deflected seamless contact flap) were considered along with an unmodified (no flap deflection) wing as the baseline case. Comparison of lift and drag corresponding to these configurations with baseline configuration (retracted flaps) will be expected to show a definite trend in the results.
CFD analysis has shown that new flap design SCTEF concept improves lift and decreases drag which is nothing but more fuel efficient flights and low noise when taking off.
