kinda related to the topic but check out this bomber, the wings panels normally leak fuel, they only seal properly when they expand at high temps at mach 3:
Good question, but I don't know if you actually adjust the fan-speed or the water-flow of a racing engine either?
The leaking fuel-tank of the SR-71 sounds suspiciously like an urban-legend to me?
Watch from 6 minutes in the video, you will see the fuel dripping out!
Yeah this is the truth, has been so since around 62. My father and grand father are both avid aviators and have talked about this plane, and many others, for my whole life.
I beleive the original YF-12A concept was meant to be a bomber as well, but the SR-71 was all about the eyes in the sky.
Neat story. On the last flight of the SR-71, it went ahead and resmashed it's old altitude and speed records.
I did a project on this plane when I was in grade 4.
The AF-12s would take the seventh through ninth slots on the A-12 production line and have them completed in the YF-12A interceptor configuration. The main changes involved modifying the aircraft's nose to accommodate the Hughes AN/ASG-18 fire-control radar originally developed for the XF-108, and the addition of a second cockpit for a crew member to operate the fire control radar. The nose modifications changed the aircraft's aerodynamics enough to require ventral fins to be mounted under the fuselage and engine nacelles to maintain stability. Finally, bays previously used to house the A-12's reconnaissance equipment were converted to carry four Hughes AIM-47 Falcon (GAR-9) missiles.
