Web3. (2.5 points) Calculate the drag coefficient for the flow at M-2 and zero incidence over the symmetric diamond shape airfoil (shown in figure on the next page) using shock-expansion theory. (Note: The lift is zero for a … WebRequired information The figure given below shows an asymmetric diamond-shaped supersonic airfoil. The orientation of the airfoil relative to the airflow is represented by a number of angles: a = the angle of attack, B = the shock angle, 0 = the deflection angle, with the subscripts and designating the lower and upper surfaces of the airfoil.

Webvarious shaped airfoils in order to generate a data base for aircraft design. Although performed a long time ago, these data are still used when designing certain appendages of the aircraft. The system consists of a series of 4, 5 and 6 digit airfoils. 4-digit airfoils ( e.g. NACA 2415): 2 - maximum camber is 0.02% over the chord, WebThe objective of this project is to analyze the performance of a supersonic wing with a sym- metric diamond shaped airfoil section. The wing is analyzed using both the linear …
WebWhen supersonic flow goes over a diamond shaped aerofoil it creates 2 different types of shockwaves, Oblique shock waves and Expansions waves. Oblique shock waves are created when supersonic flow hits sharp pointed object, like a diamond shaped aerofoil. Expansion waves are waves that expand the medium through which they are transmitted. WebJan 7, 2008 · Abstract and Figures Supersonic channel airfoil design techniques have been shown to significantly reduce drag in high-speed flows over diamond shaped airfoils by Ruffin and colleagues.

Supersonic flow over a diamond-shaped airfoil is one of the classic canonical cases for demonstrating the application of shock-expansion theory. As the supersonic flow moves over the airfoil, it encounters both oblique shock waves and expansion waves. Though the flow-field is quite complicated, the shock … See more In this homework, you will learn how to set up and solve a supersonic flow over a diamond-shaped airfoil using the density-based solver in Ansys Fluent.
