From the study of aerodynamics of wings and bodies[199], the lift-curve-slope for the airships and hybrids is derived as follows: (6)CLα=2πAR2+4+AR2 Fig. 45shows the variation of lift-curve slope with respect to Aspect Ratio (AR) and also the aerodynamic lift data of single-lob...
In this case, the nonlinear lifting surface model must allow the separation of the trailing vortices from the surface or, at least, from the side and trailing edges (Fig. 6.1b). The induced velocities due to these vortices affect the pressure distribution on the wing, so as to induce ...
The wings of an aeroplane provide lift. It is the shape of an aeroplane’s wings that allows it to fly. The top of an aeroplane’s wing is curved, while the bottom is flat. Because of the form, air flows faster over the top than under the bottom. As a result, there is less air...
This course extends fluid mechanic concepts from Unified Engineering to the aerodynamic performance of wings and bodies in sub/supersonic regimes. 16.100 generally has four components: subsonic potential flows, including source/vortex panel methods; viscous flows, including laminar and turbulent boundary ...
The aerodynamic and the vortical flow structure over simple delta wings undergoing either a pitching or rolling motion is presented. This article reviews experimental information on the flow structure over delta wings and complete aircraft configurations. First, the flow structure of leading-edge vortices...
For example, airplane wings are designed so that their movement through the air creates an area of low pressure above the wing and an area of high pressure beneath it; the pressure difference produces the lift needed for flight. This effect is typical of airfoil design. Drag forces are ...
where they can greatly increase drag. That's whysupersonic(faster-than-sound) jet planes have sharp noses and sharp, swept-back wings. Go faster still and the aerodynamic rules change once again. Athypersonicspeeds (around five times faster than sound), shorter wings work best and they need...
While the research will focus on the wing and airfoil aerodynamics for the NCSU Formula SAE car, the results and discussion will be applicable to a variety of race vehicles with wings. Due to the reduced vehicle speeds encountered in a formula SAE competition (as compared to other professional...
Assuming that the thrust is distributed evenly on the wings of the BWB and TWB, attributable to geometric issues, the thrust of the TWB has to be divided into three sections (two semi-span wings and a fuselage), which leads to a more complicated propulsor installation. Conversely, BWB can...
