Supersonic aerodynamic shapes
WebThe important specifics in supersonic airfoil design are flight speed, flow behavior, wave formation, lift, and drag-induced at high speed. Analysis of these factors is easier with CFD simulation, which allows visualization of flow behavior and its effect on the airfoil at supersonic speed. WebFor supersonic flight, the nose was hydraulically lifted, streamlining the plane's shape and allowing it to efficiently pierce the air. Delta Wing It's a classic aerodynamic problem: most...

WebSep 17, 2024 · At supersonic speeds, the drag “penalty” for redirecting significant amounts of air is magnified. That’s why engineers create long, slender supersonic aircraft with … WebIn this study, an aerodynamic shape of a supersonic wing is optimized at the supersonic cruise design point. The cruising Mach number is set to 2.3. Purpose of the present study is to maximize lift-to-drag ratio (L/D) maintaining substantial lift coefficient (CL) and wing thickness. The optimization problem is defined as:
The well-rounded, cambered airfoil sections well-suited to subsonic flight speed are generally not appropriate for high-speed and supersonic flight. Supersonic airfoils are distinctive in their geometric shapes in that they are thin (i.e., have a low thickness-to-chord ratio) with sharp leading edges. Supersonic airfoils … See more Engineers must know how to select or design suitable cross-sectional wing shapes (often called airfoil profiles orairfoils) for use on a diverse range of flight vehicles such as airplanes, various … See more The basic geometry of an airfoil is described in terms of a profile shape or envelope that defines the curvature of its upper and lower surfaces. As shown in the figure below, airfoils can be symmetric, an … See more As early as 1920, research institutions in Europe and the U.S.A. had embarked on the systematic measurement of the aerodynamic … See more Historically, the most suitable airfoils for most practical engineering applications have been obtained through an evolutionary process. In this regard, both theory and experimentation (e.g., wind tunnel testing) have … See more WebFeb 16, 2024 · In the two optimizations, three different configurations of the morphing wing which are 20°-, 30°- and 70°- sweep angle state, and three different flow conditions, which are subsonic (0.25 Ma), transonic (0.85 Ma) and supersonic (3 Ma) are considered.
WebDec 7, 2024 · To support this goal, NASA is developing the X-59 Quiet Supersonic Technology (QueSST) airplane, whose unique shape and technology are designed to turn sonic booms associated with faster-than-sound flight into barely perceptible sonic thumps. WebThe complex mathematical shape of this aircraft wing is derived to minimize drag at supersonic speeds. Ogive wings offer excellent performance at supersonic speeds with minimal drag. The main disadvantage of these types of aircraft wings is that they are very complex and manufacturing them is difficult.
A supersonic airfoil is a cross-section geometry designed to generate lift efficiently at supersonic speeds. The need for such a design arises when an aircraft is required to operate consistently in the supersonic flight regime. Supersonic airfoils generally have a thin section formed of either angled planes or opposed arcs (called "double wedge airfoils" and "biconvex airfoils" respectively), with very sharp leading and tr…
