Modeling of Airplane Wings with Winglets
We describe methods and algorithms for automated generation of multiparted airplane wings with winglets. The wings are given by one or more cross-sections (e.g. by point clouds) and their top views. The relative thickness of the wing (thickness/chord) can be varied from section to section. A rounded tip with design parameters and GC1-continuity at the crossing to the wing is automatically compu...
متن کاملEffect of Vortex generators on Aerodynamics of a Car: CFD Analysis
Flow separation at the vehicle’s rear end is the major cause of an aerodynamic drag in a car. In order to delay the flow separation at the rear, bump-shaped vortex generators at the roof end of a car are tested in this paper for two different types of car models Sedan and Hatchback. The aerodynamic analysis is carried out using GAMBIT and FLUENT for Sedan and Hatchback models. Vortex Generators...
متن کاملAerodynamic Design Studies of Conventional & Unconventional Wings with Winglets
In the pursuit of efficiency there is continued and developing interest in the subject of winglets and novel designs such as Blended Wing Body and Oblique Flying Wing. Winglets may exist in many modes, ranging from endplates, through folded wing tips to complex upper and lower surface partial chord devices. We have developed a design process that is directly applicable to the design of wings an...
متن کاملTip Extensions, Winglets, and C-wings: Conceptual Design and Optimization
Conceptual wing design analysis methods are combined with numerical optimization to find minimum drag wings subject to constraints on lift, weight, pitching moment, and stall speed. Minimum drag tip extensions and winglets are compared using nonlinear optimization. The minimum drag trapezoidal tip device depends on the ratio of the maneuver lift coefficient to the cruise lift coefficient, altho...
متن کاملThe aerodynamics of revolving wings I. Model hawkmoth wings.
Recent work on flapping hawkmoth models has demonstrated the importance of a spiral 'leading-edge vortex' created by dynamic stall, and maintained by some aspect of spanwise flow, for creating the lift required during flight. This study uses propeller models to investigate further the forces acting on model hawkmoth wings in 'propeller-like' rotation ('revolution'). Steadily revolving model haw...
