Wandering Around an Avanti

The Avantis that had been operating at Paine Field have relocated their base to Arlington instead. I think they are getting maintained there and so it is the new base of operations. One of them arrived while I was up that way and it parked up on the main ramp. I wandered out and chatted to the owner as he put the plane away for the evening and then, once he had gone, I continued to get some shots. The airframe is a selection of interesting shapes so I was trying to find good ways to shoot it.

The fuselage shape tapers aggressively, there is the front wing, the main wing and the tailplane and then there are the engines and their props. Lots to try and work with. The engines are interesting in that the exhaust from the PT-6s blows right on to the roots of the props. This heat must be a form of deicing but it also must require something of the blade construction to manage the heat. There is some sign of the particles in the exhaust in the dirt patterns that form across the blade roots.

I’ve said it before and I’ll say it again. The Avanti is an amazing looking aircraft. The combination of cabin size and performance is unmatched by turboprops (and a lot of jets too). I wish it was more successful. Lots of people focus on its noise but that doesn’t bother me. However, having looked at those props in more detail, I can’t help but wonder how much of that noise is from the exhaust interacting with the blades rather than just the blades themselves.

All Star Flyover Jets But Only Just

The All-Star baseball game was in Seattle this year. Baseball is not my thing so I wasn’t paying too much attention although I did have a meeting near the stadium and discovered just how much a parking garage will charge on the day of the All-Star game! However, they did have some USAF F-35As in town for the flyover proceedings. I was south of the city later in the day and started to head north close to the time when the game was due to start. I had been hoping that I might get up to Boeing Field for their launch but, as I drove north, I could see the jets pulling off their run over the stadium.

I figured they would recover quickly but headed for the approach end of Boeing Field just in case. Fortunately, they had taken the scenic route and had been touring around Puget Sound. I was there in plenty of time for their landings. One thing that I had not really noticed before about the F-35A is the approach angle of attack that the jet adopts. The planes seem to have quite a nose high attitude when on approach. The radome is short so the field of view is probably not a problem, but I was surprised I had not spotted this previously.

I got the jets all landing but they were really a series of repetitive shots of similar looking jets. Nothing too special but still nice to have a different jet here for a while.

Finally, The Aero 45 Is Airborne for Me

Leave a Reply

I have seen the Aero Vodochody designed and Let Kunovice built Aero 45 before at events. However, it was always parked and never in motion. I think it is such a cool looking like aircraft and reminds me of a mini Heinkel HE-111. I really wanted to see it flying and I have had two opportunities this year to do so. First it showed up at Concrete for the fly in. This was great news as I got it landing from close proximity and then again when it took off.

It was not a lot later that the Arlington show was setting up. I wasn’t going to be at the show but I was there the day before for some warbird flying and the Aero 45 was coming in to be on static. (This was a repeat of the first time I saw it in person which was also at Arlington.). Not so close this time but another opportunity to catch it in flight. What a cool looking plane. Glad we have it up here in the PNW.

Dreamlifters Are Still Here Occasionally

Leave a Reply

The end of production of Boeing 787s at Everett meant that there was no longer a need for the Dreamlifter operations to support Dreamliner production. However, while the Dreamlifter base has closed, there are still some production activities at Everett on the 767/KC-46 line that require large structures to be delivered and the Dreamlifters are used for this sometimes. I understand at least one of them is currently stored, but the others are active.

I only rarely find myself at Everett when the Dreamlifter is there, but it has happened a few times over the last few months. Here are a few of the shots I have got since these things became a little bit rarer up this way.

My Buddy Was Flying This

Getting a British Airways 777-200ER arriving at SEA would not normally be a priority unless the light was great and I was going to get Mt Rainier in the background. If the weather was cloudy and it was arriving from the north, might not seem to be that much of a deal. However, if it is being flown by someone I know, that is a different story. My friend, Paul, was the skipper on this flight and I was meeting him to have some time around Seattle before he headed home the following day.

The clouds were a shame but the light wasn’t totally bad. I figured it would need a bit of work in post to try and make the best of the shots but the lack of heat haze did help a bit. I was able to grab a few shots of the jet as it came down the approach and then as it was over the threshold prior to touchdown. Not the greatest shots Paul will have of him flying but, hopefully there are not too bad.

Typhoon Air Data System

Working through some older shots for another project, I ended up looking at some shots of an RAF Typhoon displaying. As I was zoomed in on some of the shots, it was interesting to see the air data vanes on the underside of the front fuselage as the plane maneuvered. There are several vanes around the underside of the front fuselage and the differences between them can tell yaw and pitch angles. In one shot when the jet was climbing straight up, the vanes are all pointing in similar directions. Shortly before this, as the jet was pulling hard, the angle of attack was higher and the flow up around the front fuselage results in some significant differences in vane angle.

This is the sort of thing that is very important when designing and clearing a flight control system. We had a front fuselage wind tunnel model for the Typhoon during the development program. This was used for intake design but also for air data system modeling. The way in which the various vanes move is vital to understanding the control law requirements. It is also important when considering failure modes. If one vane should fail, how much it impacts the flight control behavior and how much the system detect the failure. Will the aircraft be vulnerable to control loss in the interim? The Tornado did not have as complex a flight control system, but it did have augmentation of the controls and, as it rolled, you would get quite different readings from the angle of attack probes on each side of the fuselage. How much of a difference was normal versus what was a failure was an interesting analysis problem which I enjoyed working on. My days on Typhoon were relatively limited and shortly before first flight so I never got involved with the results of the testing program, but I do enjoy looking at the resulting aircraft whenever I get the chance.

Wichita’s Finest is Everywhere in the Parks

Kenya and Tanzania have many small airstrips scattered around the countryside including in the national parks. These provide quick transfers between locations if you are willing or able to pay and don’t want the long and bumpy road trips. There are a variety of types that are used for these services and I shall show some others in upcoming posts. However, one type does dominate.

The Cessna Grand Caravan is everywhere in the region. It has the right size for many of the trips, it has sufficient capacity for luggage with the baggage pod beneath he fuselage, it is fine with the rough surface strips that are in most places and it is PT-6 powered so very reliable. We saw tons of them during the trip and also got to experience a flight on one. I was surprised to find it was a 1×2 configuration. I had assumed that they were 1×1 but not in this case. It got a lot of us in there but getting in and out was not an easy process. The aisle was minimal!

I have no idea how many Grand Caravans there are in use in rural Africa but I imagine that Cessna has delivered a ton of aircraft from Wichita to the region. I suspect that the best replacement is another Caravan. The Islander might once have been this sort of workhorse but the efficiency and reliability of the Caravan must be what has made it so ubiquitous.

Hot Air Balloon Searching for a Landing Spot

Leave a Reply

Nice evenings during the summer mean balloon flights over Woodinville and the surrounding area. I was driving home one evening and, as I came up I-405, I could see a balloon that looked like it might be close to home. Rather than turn towards the house, I headed for one of the nearby fields that has been a landing zone for balloons before (and that have made it into posts on here). When I got there, the balloon was close but was tracking slightly west of the field so no way it was going to make it in. It was heading towards the town so I decided to drive towards the south side of the town to see where it might end up.

I was coming around the south side on the road that skirts the town and the traffic had come to a halt. This was because everyone was watching the balloon low overhead. I actually took a shot through the sunroof of the car as it came low over me. I looped around the roundabout but didn’t take the south exit because the crew seemed to be heading that way and I didn’t need to crowd things.

I went around to the next road and looked back across the fields as the balloon continued on its way. It wasn’t touching down so I guess the area was not ideal. I figured I might head a little further south and see if it came even further. I took the road to Redmond and pulled off at one of the field entrances. Sure enough, they were still drifting south but looked like they might finally be getting close to landing. I didn’t shoot much video, but I did get a little to emphasize the way the balloon was drifting through the trees. As I watched it, the ground crew pulled up and started honking at me. They were incredibly rude. As soon as I saw them arrive, I was getting out of the way. Not my fault that they were struggling to catch their balloon, but they behaved like everyone should just get out of their way. I did anyway but, if you are reading this balloon crew, don’t be assholes to bystanders if you are struggling to recover your balloon and its passengers.

The Cormorant Beats Me Again

Leave a Reply

One of my goals for going to the air show at Abbotsford this year was to see a Cormorant fly. I know this would sound like my normal interest in the bird species but this time it means the AW101 version that is flown for Search and Rescue by Canada. Sure, I have seen plenty of 101s over the years with the British and Italian examples, but I have never seen a Canadian one before. It was due to display during the show. When I got there, I was delighted to see it sitting on the operating ramp.

However, my optimism was unjustified. There was no announcement during the show about what had happened to the SAR demo, but it just didn’t happen. The day shows did get the demo, but the Friday evening show was a no go. It was a fun show, so I wasn’t too disappointed, but it was a little frustrating to still have never seen a Cormorant airborne. One day…

Concrete Fly In

The time between me doing something and its appearance on the blog can vary wildly. Sometimes, I will aim to get something squeezed in here soon after it happens but that is the exception. Usually, I have stuff posted out quite far in advance. As I come up with new topics, they get added to the schedule and, if a topic doesn’t get written about promptly, it can really disappear into the distance. Such is the case with the Concrete fly in of 2023.

There will be several posts that make it on here from that event in the coming weeks. I have started writing them up but some of the specific topics will take a while to appear. However, I shall start things off with a more general post about the fly in. Held at Mears Field in the interestingly names town of Concrete, it is a popular gathering of planes from around the region. There is a single runway running east/west in the valley and the planes park up on either side of it. You are able to walk across the runway at a couple of locations (or further away from them if you want to avoid the air cadets) so just keep you head on a swivel. The wind seems to change midway through the day, so arrivals were from the west in the morning and the east in the afternoon.

We set up at a spot near the threshold on the eastern end of the field and it provides a good location to watch the landings and the takeoff rolls. Sometimes, it is easy to forget that you can walk around, and you find you have stayed in one place for ages getting similar shots. I did try and mix it up from time to time but it was rather sunny and warm and the shade under the wing of a 170 was pretty appealing.

Since I was shooting a lot of light aircraft, I decided to try and make the shots more interesting by keeping the shutter speed low to emphasize speed. The downside the this is that you are very close to the runway so the parallax effect is quite pronounced. You can also just miss a ton of shots but why not have some fun. Few of them are ones you can’t afford to miss. It does mean a sharp nose is probably combined with a blurry fin. This will really annoy some viewers and others will never notice. Since I am shooting for me, I’m the only one that has to care!

More to come of some specific planes and events from the day out with a regular crew of aviation loons.
