Comparative Study and Aerodynamic Analysis of Rectangular Wing Using High-Lift Systems

High-lift systems are designed to expand the flight envelope and have a most important effect on size of wing, economy, safety many airliner configurations. Even small increment lift using high-lift system can significantly impact an aircraft’s profitability. The effective design airfoil shape with required aerodynamic performance is still difficult. In early days, designs airfoils were randomly set up tested in flow section, then, Wright brothers emerged cambered section. NACA has provided appropriate definition that supports us making formulas, not randomly. This paper describes influence analysis wing flaps at various deflection angles. Aerodynamic variables for aircraft which made 6412 model without flaps, been studied angle attack (AOA) (i.e., -4, -2, 0, 2, 4, 6, 8, 10, 12, 16) different Mach number 0.2, 0.3, 0.4. Also, was done 15000 ft altitude check density effects real-time applications. coefficients drag gained by examining pressure distribution over surface wing. Lift increases as approach ascends from low high attack, extreme produced specific point. After that, when further, component increases, so stall occurs point time. results showed obtained maximum 14°, value started decrease. CFD computations performed Ansys Fluent performing hybrid mesh ICEM-CFD. configurations parameters like altitude, gap distance between main slotted flap compared identify better
