An Axis System for Five and Six Degree of Freedom Airplane Dynamic Problems

extend to infinity (where B = B^, the constant applied field), it follows that B = constant everywhere. In other words, for the particular case of (a) an infinite, straightsided, two-dimensional (x, y plane) wedge, (b) moving with constant vertical velocity (c) impacting on a semi-infinite incompressible perfect conductor (d) with applied magnetic field BA = BAk, where BA = constant, the magnetic field has no effect whatever upon the dynamic behavior of the wedge—that is, the pressure on and velocity of the wedge may be determined from the usual conservation equations of incompressible hydrodynamic theory, without regard for magnetic effects. From a similar analysis of the steady-state two-dimensional form of Eqs. ( l ) (3) , we may conclude the magnetic field B is constant along each streamline for these flows.
