Here's a couple more generic Hypersonic designs.
As for that GE design, the L-M Falcon program proposal has similar inlets, in that they're very long at an acute angle to the airflow. This is done to minimize the area of the inlet lip that requires active cooling, which would basically be the "webbibg"/sections between the spikes that is more orthogonal/perpendicular to the airflow. By keeping it to the small areas at the back of the inlet it allows them to minimize weight with regard to the active colling requirements. There was an AIAA article online that showed a good CFD pic regarding this, but I can't find it atm.
