Flow Viz on a Hornet

A long time ago (but not in a galaxy far, far away), I had a visit to the naval air station at Fallon. The weather was not ideal for the visit, and we had a bit of a disappointing result when it came to flying jets. I did spend some time on the ramp, though. A Super Hornet was marked up in squadron colours, and this was what initially caught my attention. However, as I looked at the jet more closely, I was fascinated by the dirt streaks emanating from the fasteners on the rear fuselage panels. These marks clearly showed the path the flow takes across this part of the airframe.

Tanker Dwarfs the Ferry

The Guemes Island ferry was busy operating across the strait between the mainland and the island while I was there.  Just as it was readying to depart for another crossing, a tanker was making its way up the strait towards Anacortes.  I was wondering whether the ferry would make a quick dash across before it got there but they decided the discretion was better than valor and instead headed up the strait to turn and cross behind the tanker.

The closer that they got to the tanker, the more apparent the difference in scale between the two vessels became.  When you see large ships at a distance, it is easy to lose track of just how large they are.  Put something you can appreciate the scale of close to them, though, and you rapidly see that they are really big.  This isn’t even a big tanker by the scale of tankers.  The biggest vessels are truly enormous.  I remember as a kid that one of the largest tankers was berthed in Southampton for a few years when it wasn’t in demand.  That thing was massive!

Is There Any Oil in This Thing?

C59F8061.jpgParked up on the ramp at Erickson’s facility was a DC-7 tanker. It didn’t move while we were there so it became the target of a number of photographers at any one time. I shall show more of it shortly but one thing that caught my attention was the amount of oil on the engine nacelles. Old piston engines are well known for consuming oil at a prodigious rate and this beast was no exception. It seemed to have done a great job of relocating the oil from the internals of the engines to the outside of the nacelles. It made for some great patterns and this was what distracted me for a while as I walked around the aircraft.
