Spying on the Trout

Leave a Reply

On a few occasions, when we have been in Stockbridge, I have spent a bit of time watching the trout swimming in the river where it runs under the road and alongside the pavement. This has got me thinking about how to get some good video of them. I figured the Insta360 X3 might be something to try. The invisible stick is pretty long which would allow it to go into the water and the camera itself is waterproof. I was too sure how the image quality would work out but, when we went to the Trout’n’About festival in the town, I took the camera along.

Initially the arrival of the camera spooked the fish which was not a surprise but leaving it there for a while meant they got used to it. It didn’t hurt that some people were throwing food into the river which the fish were way more interested in. I wanted to use the app to control things, but the connection was lost when the camera was under the water. Instead, I just started recording before putting it in the water. The images are not great, but they do give a good view of the fish moving around. Check out some video below.

Weird Prop Vortex Effects on the Background

Leave a Reply

The aerodynamicist in me gets a little happy when I see shots that have the visible effects of the flow fields around a plane. Shock waves will be the most obvious example, but a trailing vortex can also cause some interesting refraction. The propeller produces a strong vortex from each blade and every once in a while, you can get a shot where the background provides enough of a pattern to allow the prop vortices to show up. I was reviewing some shots from Boeing Field of a Malibu Mirage with the PropJet turboprop conversion when I saw exactly this. Head on it can show quite well but getting it from more of a side on position was a nice surprise. Thankfully, the hangar doors in the background have vertical corrugations and this allows the flow to be seen in both directions due to the upward and downward moving blades.

These Old Cars Are a Bit Temperamental

Leave a Reply

There was a parade of old cars as part of the Festival of Flight at the Shuttleworth Trust. It was a very hot day so possibly not ideal for cars that were designed a very long time ago. Sadly, one of the vehicles found the conditions not to its liking. The driver had to hop out and see what could be done to sort it out. There didn’t seem to be an immediate solution as, the last I saw of it, a bunch of people were pushing it away. I hope it was nothing too serious. I suspect owning a car this old comes with regular moments of this type.

We Can See Where the Fuel Is

Leave a Reply

I have an old post from SFO on a similar theme to this one, but I make the rules on this blog and this post isn’t violating any of them. (If you want to know what the rules are, let me know and I shall try and come up with some.) When I jet descends from altitude, the fuel the remains in the wing tanks will be very cold. The warmer and moister air lower down can result in the formation of ice on the underside of the wings where the remaining fuel is pooled. This Delta A330 shows that, as expected, there is fuel at the inboard end of the wings but also, less expected by me at least, there is a tank further outboard that still has fuel in it. I like the fact that fuel is kept further out since it alleviates bending loads. You can see the shape of the access panels where the ice is forming.

Finally, a Little Sun on a Cyclone

My first encounter with a Canadian Cyclone was in the middle of a storm when it was incredibly gloomy. The next time I got to see one flying, the conditions might not have been so bad, but they were definitely dull! I figured I would just not get to see one in good light and, given that it has a dark and dull grey paint finish, it really sucks in whatever light there is. However, I did finally get lucky when I saw one on the ground at Abbotsford. A bit of sun at last. Sure, not flying and might not be the greatest but it was definitely a step up.

Some of Lyon’s Trams Look Cool

Leave a Reply

I was in Lyon for a couple of days for a work trip. Lyon has an extensive tram network, but they don’t just have regular looking trams. They are clearly bothered about design and style – this is France after all – and so the cabs of some of the trams are far cooler than the average. I don’t know how much extra it costs to get a custom cab design, but I think it is worth it when they make the system look better.

Video of TBAG’s Event

I blew parts of this one. This video doesn’t have the best bit of what I saw but, if I hadn’t told you that, you’d probably not know. When the Buccaneer was being run up, they undertook a bunch of tests on various systems. The wings were folded and unfolded. The speedbrake was extended and retracted. The bomb bay was rotated. The bit I didn’t get for some reason was the blown flaps. To get the chunky Bucc on to the small decks of the UK carriers, they utilised flap blowing. Air was ducted from the compressors of the engines to the flaps and this improved the low speed lift. It had been raining when the demo was undertaken and the blowing of the flaps was really visible with the moisture getting blown around. Sadly, that is not in this video. Everything else is though.

Not the Oldest Tree I’ve Seen, But…

Leave a Reply

A walk we took through the New Forest brought us to the Knightwood Oak. The New Forest is an ancient forest, but this tree is older than many that are there. Supposedly, there were laws enacted long ago regarding the practice of pollarding trees. The fact this one was pollarded suggests it will have predated this time which suggests it might be 500 years old. That is not the oldest tree I have come across. Our travels in California did bring us to some extremely old trees too. I can’t recall exactly how old but possibly older than this. Even so, 500 years old isn’t bad for a tree.

I suspect if I had come here when I was young, you probably would have just walked up to the trunk. Now, the need to protect the tree means that an enclosure has been set up around it. The good news about that is that it keeps people out of many possibly photos you might want to take. (Funny how, when you are interested in getting photos, you are “focused” on different things to other people.) I had a wander around the perimeter of the enclosure to check out the whole tree before we continued on our walk.

A Pair of PC-24s Overhead

I was out of position one time when at Boeing Field. Being down near the museum, departing aircraft tended to be quite high by the time they got to me. This didn’t stop me trying some shots since it was something a bit different. I was pretty happy when I got a Pilatus PC-24. They are quite popular and not a rarity at BFI but still pleasing. Then I was rather surprised to get a second not too much later. The PC-24 has great short field capability and can land on grass strips too. From the underside, you get a good look at the wing planform that delivers this performance.
