Airspace Structure; Aircraft
An F35 test flight was climbing out of my airspace. He had changed frequencies to the next sector and declared an emergency. I approved FL190 on a 180 heading. Then I pointed the aircraft out to R-XY and they said 17;000 FT was approved. I called Approach to coordinate lower and direct destination. They approved 12;000 FT direct. I issued this clearance; did a quick traffic scan of the rest of my sector and realized the emergency a/c was going to clip R-ZA before descending into Approach. I called on the boundary to point out the aircraft; R-ZA said point out approved. The aircraft continued descent and landed without any issues. I had an expectation that the aircraft was going to descend more rapidly than it did. A D-side would have helped with the coordination; however there was no one in the area at the time to assist. We were very short staffed for this shift; having an extra person available to work a D side may have helped the situation.
F-35 in emergency status descended slower than the enroute Controller anticipated; resulting in an airspace violation.
