P-150: Ekranoplan: Candidate CFD models

by on Aug.31, 2014, under Art and Designs, Concepts, Inventions

I have completed most of the CAD modelling of the prospective ekranoplan models. I have created six different models to test in the OpenFOAM wind tunnel.

One with a Standard delta wing (the length of the tip chord being 0) , one with a trapezoidal delta wing (with tip chord being 10% of the root chord) and another with a trapezoidal wing (with tip chord being 20% of the root chord). All three of these wing designs have a double wedge airfoil and a biconvex airfoil

I have chosen to mount the vertical stabiliser just above the trailing edge of the wing root. This is because I am also mounting the engines to the vertical stabiliser, similiar to some of the soviet ekranoplans of the 1980’s. I need to mount them high because I need to keep them out of the disturbed airflow at high mach, and I can’t moun them under the wings due to the fact that the aircraft is flying close to the ground. The delta wing prevents me from mounting them horizontally on the fueselage. This means the vertical stabiliser needs to be made much thicker and stronger.

The modelling and mathematics on this project was quite difficult, particularly all of the constraints required to assemble the different pieces of the aircraft. I am interested to know what the coefficient of drag and other values will be when I conduct a computational fluid dynamics analysis on these models.
