Oblique Wing

Hiller Aviation Museum has another aircraft I find interesting. This is the AD-1 Oblique Wing research aircraft from NASA. I have crossed paths with this machine before. I have seen it at Hiller before but it was also still at Edwards when I paid a visit to the NASA facility there in 1990. The oblique wing concept is an interesting one. Swing wing aircraft aim to combine he low speed and high speed characteristics required into one plane by having multiple wing sweep angles. The oblique wing approach aims to simplify this by having a single wing that pivots. The sweep angle is the same but eh CG is unaffected and the pivot mechanism much simpler.

Forward swept wings are fine so, while the oblique wing looks odd, it should be practical. It will have some interesting aeroelastic issues to be dealt with but, it should be possible to engineer. Whether it will then deliver the benefits has never been tested. The AD-1 was a low speed research aircraft only but it flew many times over the years it was in service. Now it hangs from the roof of the museum.

End of the Brasilia?

“You don’t know what you’ve lost ‘til it’s gone” as the song goes. These days a number of aircraft types are fading away and the previous lack of interest shown when they were commonplace gets replaced with a sudden wish to make the most of their final days. One type that is likely to be disappearing from the skies around here before too long is the Embraer EMB120 Brasilia.

It isn’t disappearing in total but the largest operator of the type around here is Skywest. Skywest uses the Brasilia for their services and for those of United Express. However, the relatively small capacity of the type is making them uneconomical to operate – something the age of the airframes is probably not helping. I think I have only flown on one a couple of times when I was connecting on Comair from Cincinnati to Greenville-Spartanburg (and back) in 1990. I recall it being a rather noisy beast inside.

As Skywest draws down their fleet, they will soon be gone. Ahead of that time, here are a few shots I have gathered over the years.

Hiller Aviation Museum

I took a trip to the Hiller Aviation Museum recently. The trip was to see a speaker who was appearing there and that will be part of another post. However, I did have a good look around the museum while I was there. Located on San Carlos Airport, I have been to the museum a few times in the past when I was visiting the area for work but I hadn’t been since we moved west. My buddy, Hayman, is a volunteer there so I have no excuse for not having been recently!

A few things have changed since I was last there. The SST mockup has now gone freeing up some space for other exhibits. This post isn’t a comprehensive review of all that is there. It is more a focus on some of the things that caught my eye while I was walking around. One item I have to mention is the Boeing Condor unmanned vehicle. It is a cool thing to see but, since it is so large, it is squashed in amongst all of the other exhibits. I decided that I should try and get something to show it in all its glory. There was a balcony which would have had a better angle but that was restricted to some simulation experience. Instead, I decided to try a pano approach instead. It came outs reasonably well although taking out some of the distortion in post processing was necessary.

I had another go at a pano with the interior of the Albatross. It is a lovely looking aircraft with a great interior which is visible through the side door so getting too much of a shot of the inside was hard to do. A pano gives a bit more of a feel for the layout in there. It looks like a nice plane to take around the world!

The museum is great and the gift shop is pretty cool too. I have to admit a model helicopter left with me and now sits on my desk. It is an AW101 in Canadian rescue colors and looks pretty sharp!

More Head On at SFO

Leave a Reply

After my visit to the Peninsula was done, I decided to head back to SFO. This time I wanted to have another go at head on shots. In my post here, you can read about my first efforts at this and how the heat haze was a problem. Winter has better chances since the sun is lower and the heat haze reduced. However, the sun does go down earlier so there are fewer flights departing while you can still shoot. They do tend to have nicer light though.

The Emirates and Lufthansa A380s were the main things I got while I was there. A British Airways 747 was scheduled out but the sun was dropping out of sight as he taxied so I didn’t wait. He actually took off over me while I was at the gas station. He had nice light once up high but the runway would have been in shade by then so I don’t think it was a mistake.

I also got some corporate and rotary wing movements while I was waiting. Unlike last time, the 01s are now back in use so only the heavies departed my way. It was fun to look back up the approach at some parallel arrivals and also to see the departing jets as they crossed in front of me.

SFO from the Bay

Leave a Reply

While not a specific trip to shoot planes at SFO, I did have some time by the bay to get some shots of the planes as a result of being on the peninsula for another purpose. It was earlier on a Saturday morning that I found myself there. Winter is a better time to shoot at SFO since the heat haze is less of an issue. Even so, I was surprised to see how much haze there was for shots that were looking back towards the approach. I’m not sure if this was a result of the tide being too far out exposing the mud flats or not. The angle of the light early is also a bit far back but still there were some options.

I was pleasantly surprised by my luck while I was there. Despite there not being too much traffic, I had a couple of parallel approaches take place. One was a China Eastern A330 with a United A320 in close contact. This was a very cool thing to see. A couple of United A319s also were quite close together on another approach but they had just slightly more offset.

Fat Albert tearing the turf

Lots of my retro posts come about because I was doing something else that led me to a shot I had forgotten about. Having a system like Lightroom is a great way of throwing up some interesting shots that appear when you run a keyword search. In this case, I was looking at an old air show which had featured the Blue Angels. As is usual for their shows, the first part of the demonstration was the USMC C-130 display, Fat Albert.

At the end of the display, they land the C-130 and throw the props into reverse aiming to stop as quickly as possible. (A little bit of bouncing is also apparent in the top shot!) On this occasion, I guess the ground alongside the runway was not too stable. The wash thrown forward by the props ripped the turf up ahead of the plane and threw it into the air. It made for a pretty dramatic view. Even through the viewfinder, I could see what was going on. The shots afterwards just confirmed how much material they threw around that day!

Preserved Blackbirds

If you ever want to find a way to lose a lot of time (this assumes you are an aviation guy), spend time on the Lockheed Martin in-house magazine’s website, Code One. Edited by Eric Hehs (with contributions including some by Jeff Rhodes), the magazine is full of great stories about Lockheed Martin products past and present. I should say I have met Eric and Jeff through ISAP and both are great guys so I am biased. When I am supposed to be doing something, Code One is the worst thing for me to look at since I can get lost in story after story. Recently they were celebrating the 50^th anniversary of the SR-71 and ran a piece about preserved Blackbirds. This got me wondering how many of them I have seen and photographed.

I will start by pointing out I saw them in service as well as preserved. Mildenhall was home of Detachment 4 of the 9^th Strategic Reconnaissance Wing for many years. Blackbirds made an appearance at the Air Fetes that were held at Mildenhall in those days. I also saw a couple from outside the fence during normal operations.

It turns out that, while there are a lot of them around, I have seen quite a few. Some I have seen but not photographed which is a little frustrating. However, most of the ones I have seen have made it in to the collection. Here are a selection of shots. (These also include A12 and YF-12 airframes so not all SR-71s but I doubt you care about that.)

Apache at Dayton

Leave a Reply

One display at Dayton that I liked was the US Army Apache display. I have seen a few displays by Apaches over the years but they are not a regular feature of shows. The Apache is an impressive looking machine and given its nature, it can be kept close in front of the crowd to make a display that never loses your interest. Service pilots don’t tend to put the machine through as aggressive a flight demo as a company pilot might when trying to sell it. However, they do still show it off well.

The subdued finish on the Apache makes for a harder time getting shots on overcast days. However, it does take away the problem of harsh shadows on an already dark airframe. The subtlety of the different greens on the airframe are hard to show in some cases but here they do actually become apparent.

Smoke Squadron

I previously talked about the visit to the Vectren show at Dayton a few years ago. One of the more unusual acts to make it is a team that apparently has a track record of appearing at Dayton and that is the Brazilian team, Esquadrilha da Fumaça or Smoke Squadron. They are equipped with Embraer Tucano turboprop trainers and the performance characteristics of the Tucano make for a tight display in front of the crowd combined with good maneuverability for the formations and the individual aircraft.

The weather was not great with low cloud and flat lighting but the lower speed of the Tucano meant that a good display could be presented, even if vertical maneuvering was restricted. The formations were tight and some good configurations could be set up with the planes maneuvering around each other during passes. I was disappointed to see how few shots I had of some passes. Now I would have a lot more to choose from but I guess I spent less time shooting in those days.

I suspect a lot of people have not seen this team so I am posting a lot of different shots in here. I would certainly like to see them perform again at some point in the future. I shall have to see where they next appear in the US.

BAe 146 Demonstration at LCY

In my youth I had one of the coolest jobs I have ever had. I spent a summer working for the Civil Aviation Authority (CAA) in London as part of their noise measuring unit. I spent a lot of time traveling to various different airfields to make noise measurements of the air traffic. I often took a camera along with me on these jaunts.

One trip was some weekend working – overtime! At that time, London City Airport was relatively new and was a turboprop only airport being served by Dash 7s, principally of Brymon Airways. Very different from its current role, it was still a relatively new airport with a shorter runway. There was a lot of interest in adding jet service to the airport with the BAe146 seen as the type that could meet the requirements of the glideslope as well as concerns about noise. This is where we come in!

A demonstration was set up one weekend with a couple of 146s operating from the airport. We were there to take some noise readings to compare them to the turboprops. (As an aside, I felt the noise from the Dash 7s was far more intrusive, even if the readings were actually lower than for the jets.) We went along with our noise measuring gear and took a bunch of readings. There was a period during the day when the flying wasn’t taking place and we were allowed to go to the airport to get fed. Since we had CAA passes, we also got to head on to the ramp.

These shots are what I got that day. Nothing too impressive as tends to be the case for my old stuff. The original scans showed up a lot of damage to the negatives which required much time in Photoshop to take out the worst of it. Still not the cleanest of images but a day that won’t be repeated which is enough to justify a post and a chance to share an old experience.
