Abstract:
1. An aerodynamic fairing secured to, an exterior surface of an airborne mobile platform for enclosing an electronic device supported on said mobile platform, the fairing being positioned on said exterior surface downstream from a nose of the mobile platform, so as to be in a boundary layer when said mobile platform is in flight, the fairing comprising: a top portion; a pair of side portions extending from said top portion to define a volume, said side portions extending substantially perpendicular to said top portion; a chord length designated by X; a chord thickness at a local center line representing a thickness designated by Z; wherein a ratio of Z/X lies within a range of about 11-13%; said fairing further having a drag coefficient that is relatively constant and less than a value of about 0.10 below an airspeed of about Mach 0.9; said fairing further having a peak Mach number for airflow over a longitudinal centerline of said fairing that is no greater than about 1.2 at an airspeed of said mobile platform of about Mach 0.85; said fairing further having a frontal portion, said frontal portion forming an angle at a half height point thereof of between about 20 degrees to about 32 degrees, and having a pressure distribution (Cp) that is positive at a trailing edge of the fairing; and said volume of said fairing being sufficient to fully enclose said electronic device underneath said fairing when said fairing is positioned over said electronic device and secured to said exterior surface of said mobile platform.
