A light airplane has 35 -ft effective wingspan and 5.5 - \(\mathrm{ft}\) chord. It was originally designed to use a conventional (NACA 23015) airfoil section. With this airfoil, its cruising speed on a standard day near sea level is \(150 \mathrm{mph}\). A redesign is proposed in which the current conventional airfoil section is replaced with another conventional airfoil section of the same area, but with aspect ratio \(A R=8\). Determine the cruising speed that could be achieved with this new airfoil for the same power.
