Ripples in the Skin

The construction technique for aluminum aircraft fuselages is known as semi-monocoque. A monocoque structure takes the entire load through the shell of the structure. In airframes, the skin is very thin and so frames and longerons are joined to the inside to provide additional rigidity while the skin still takes a lot of the load. If you haven’t ever seen the cross section of an aircraft structure, you may be surprised to see just how thin the skin panels actually are. They are perfectly up to the task of pressurization and bending loads so no need to panic.

An outcome of this design approach is that the panels between the frames and longerons can experience some load directions that induce a measure of buckling. Nothing that is beyond their elastic limits but something that can be apparent if the light comes from the right angle. The lower side of the rear fuselage of the Boeing 757 is an area that is susceptible to this in certain flight conditions. I saw a number of them recently – both -200 and -300 models – and they both were showing visible distortion of the panels. The sun angle meant that the shadowing of these areas was apparent.

The 757 is by no means the only aircraft to experience this phenomenon. The B-52 Superfortresss is a jet that shows this effect on plenty of occasions. I have heard people comment on it being a function of the age of the airframes but it is more of a result of the design of the basic structure than anything else. Certainly nothing to be immediately concerned about.

Collings Foundation at Livermore

Leave a Reply

The annual visit of the Collings Foundation to Livermore with their vintage warbirds is a popular event with many people turning out to look at the planes and, in some cases, fly in them. This year I didn’t plan on spending a lot of time there but I did head down for a while to check out how things were progressing. It was a hot day so the heat haze was playing havoc with shots as usual but there was still enough to see.

I had pondered what other spots might be useful for getting a shot or two and tried wandering down the street. However, the area is not pedestrian friendly so that idea didn’t progress too far. I did wrap up the day by driving to the public golf course at the end of the field to see whether I could get a different perspective on the departures. It wasn’t a bad spot but not somewhere I shall try again unless there is a good reason. You get a brief view and have to grab your shots before the planes are behind the trees.

Whatever the limitations, having the P-51, the B-24 and the B-17 on display is always nice and worth taking time out for given that it is so close to home.

Castle Air Museum

It’s quite strange to think that I live about 90 minutes from a major air museum but have not been to it since moving here. Such is the case with the Castle Air Museum in Atwater CA. Located on the edge of what used to be Castle AFB, the museum has an extensive collection of Cold War and Second World War types, predominantly from the US but also with a variety of types from other countries. The majority of the collection is located outside which, given this is the central valley, should mean it is pretty sunny. How I managed to get there on a cloudy day I do not know. However, it was indeed overcast when we started walking around. Things did clear up a bit later on, though, so I actually went back to get a few extra shots of things I had seen early on.

As a one-time SAC bomber base, there are quite a few large bombers on display. From the B-29 and B-50 through the enormous B-36 Peacemaker (got to love irony) up to the B-47 and B-52 strategic jets, there are all sorts. Some rarer bomber types are also on show. Not necessarily successful ones but they add to the collection. The Brits are also represented with a Vulcan on display.

It isn’t just bombers though. Plenty of fighters and trainers are included in the collection and a good number come from the US Navy so, despite the base having a USAF history, they have covered both services well. There is enough space to have all of the aircraft well spread out so you can appreciate them from many angles. You also get quite a walk in if you take a look at everything.

One of the nice additions is an SR-71 Blackbird. There are a few SR-71s on display but not a huge number and seeing another one is always cool. However, they are quite tricky to photograph, particularly outdoors when the black paint scheme really makes for a strong contrast with the daylight. Still worth a go though.

There are a few types on display that are worthy of a little extra time so I may post about them separately. If you have even a vague interest in planes, though, make a trip to this museum. Nancy came along and, while she is not a big fan of planes, she found the variety of types quite interesting. High praise indeed!

CL-215s

Canadair were a company that put together some odd projects. Before they became part of the Bombardier family, they produced a business jet and a water bomber. The Challenger (which came from an earlier Bill Lear project) has gone on to spawn a large number of production aircraft of various types. The CL-215 is a different story.

Water bombers are a very useful tool in fighting fires. Within that sphere, the CL-215 has been a great success. That is not a huge world, though, so production has been modest. Even so, the original piston powered aircraft has gone through a turboprop conversion program and the current production model, the CL-415 has turboprop engines as well as airframe and systems enhancements. Production is at a low rate but they do still come out of the factory.

I was quite pleased to come across a couple of the planes that are still fitted with the original radial engines. The already chunky lines of the plane go quite well with the bluff profile of the piston engine – something the turboprop lacks a little. These planes weren’t flying. They were awaiting their next project. With the fire season approaching, I imagine it won’t have been too long after I saw them before they were back in action.

Planes of Fame Review

After a period of relative inactivity, I have been a bit busier recently on getting material together for GAR. After a piece on the tenth anniversary of the first flight of the A380 and a review of Dream Machines at Half Moon Bay, I had my first real show of the year. I took a trip down to Chino for the Planes of Fame show. This was the first time I had been to this show, despite the fact it is one of the highlights of the airshow calendar.

The piece went live on GAR recently and can be found at this link. http://www.globalaviationresource.com/v2/2015/05/12/airshow-review…e-airshow-2015/. Meanwhile, here are a few shots that I liked from the event. I will say how much I enjoyed the access you had at this place and it was a very pleasant change not to be herded out as soon as the flying stopped. It was also a lot of fun to hang with Mark, Kev and Jim. Their company made a good weekend great and also meant I didn’t miss the sunset show! Cheers guys.

B-58 Hustler

A few people I know recently had pictures up on Facebook of the B-58 Hustler bomber. This was a supersonic bomber from the cold war era. It was a beast of an aircraft and one that I would love to have seen in action. Sadly, they were all withdrawn from service long before I had a chance to see one. However, there are a few of them scattered around museums and I have seen them in person, even if it is not quite the same. I thought I would throw in a few shots of my own of these outstanding looking jets.

Night Launches

Leave a Reply

When the daylight flying activities are over, there is still the night and Red Flag has a night mission that is flown on most days. Therefore, after dinner, you can head up to a spot north of the speedway where there is a great view over the base with Las Vegas in the background. It is dark up there so there are not many good chances for shooting the jets but you can sometimes get some shots of stuff flying over if it lights itself up.

However, you can get some shots of the base with the launching jets showing up either from their afterburners or from the heat distortion they leave behind.

The other thing is to run a time lapse and see the jets moving around on the base and then streaking off into the sky. I ran a couple of them over two nights. Below is the result of one of them. Two things to note. First, the launch was very spread out. The main jet launch was actually quite late and I was tired and cold so cut short the sequence while they were still heading out. The second is that a weird optical effect shows up in the video. It is a movement of the image a bit like heat haze. However, since the shots are taken over such a long period of time, you would think that would not be an issue. Something is going on though so if anyone has any suggestions, feel free to comment with your thoughts.

B-2 Quest

Leave a Reply

The B-2 has been around for a long time now. However, with only 20 of them around, they are still a rarity and good to try and catch. We were having mixed luck with them during Red Flag. We were late to the runways and so missed the launch. I got an iPhone shot and that was it. They were almost the last aircraft to recover so, again, we were on the bus when they landed. This was more frustrating since the sun was low and right down the runway making them look amazing. I was on the wrong side of the bus so just watched what I could see through the opposite windows. My colleague, Chris, was on that side so did get some shots for the feature.

The following day I saw them launch. Early shots at Nellis from the speedway are not the best. They are quite heavily backlit so getting a good shot is not really practical. They also launch the B-2 from the far runway so it is a bit further away as well. When they were coming back, I had an idea. There is a location a lot further out which is quite good at night for looking over the field. You are in line with the runways so I thought it might be a good spot as the B-2 recovered. They would be relatively low since they were landing and the great evening light would be right on the nose.

As the recoveries wound up, I packed my gear and left the rest of the guys on the speedway and drove off. I was getting quite close to the time I needed to leave for the airport so I was ready to get going as soon as they came in. First I got the tankers coming back. They did a bit of pattern work which was a bit disappointing but not the end of the world. I could see the crews de-rigging the cables since the B-2 and Sentinel cannot trample the wires. Then the Sentinel came into view. The runway still wasn’t clear so I wasn’t surprised when it broke off the approach and flew a pattern. Again, a bit disappointing but not too bad.

Finally the B-2s came into view. Time was now passed when I really should be gone but I had waited this long so I wasn’t going to quit now. The jet came down the approach and right over me as planned. It looked great. It was being followed by the other which then broke off its approach. I figured I had tried my luck enough and started to pack up. Then the first jet flew a go around and went into the pattern. I can only imagine how good the shots were that the guys at the speedway got as it flew around in the lovely evening light. I hope they were good. I was pleased with what I got so all was well. A dash to the airport went well and I made the flight without too much trouble.

Typhoon Time

Leave a Reply

One of the reasons I was keen to cover Red Flag this time was the presence of the RAF Typhoons. I worked on Typhoon many years ago and, while they are a common sight in Europe these days, I don’t get to see them very often. These aircraft had also been upgraded with the latest capabilities which they were testing during the exercise.

Getting close to them during the launch, recovery and from outside the base as they were in the pattern gave some good chances to get some shots and to enjoy something I had a tiny hand in many years ago.

Red Flag Launches

I was back at Nellis AFB recently for another Red Flag exercise for Global Aviation Resource. Chris Wood and I were there to cover it and the piece we put together can be found at this link. After the last visit to Red Flag when a security issue resulted in all of the media being escorted off base just before the launch, I was hoping for better luck this time. Fortunately, we did pretty well. The launch went well and, while the light was a bit poor for the departures, it got better as the day went on.

Standing between the runways as the aircraft go off each side is pretty cool. We had a lot of USAF assets this time but also some Navy Growlers and RAF Typhoons. An RAF Sentinel was a nice addition – particularly as it was the aircraft with the squadron markings. One unfortunate element was that the launch was earlier than had been scheduled for our visit and the early aircraft off included the B-2s. We were still on the bus when they launched. I managed to get a shot with my phone out of the window but that was it. I do actually quite like the shot so all is not lost.

The feature has many more shots but here are a few to give you an idea of what was there.
