An Original Lynx is Welcome

The Westland Lynx was a popular type and it sold well around the world. However, time has moved on and many operators have replaced their examples. The AW159 Wildcat has been the successor in some operators but other types have replaced them for most countries. Having an original Lynx still in use is a nice treat and the German Navy has not yet replaced all of theirs. They brought one to RIAT this year and the smooth lines of the original design are relatively untouched on their versions. They will soon be gone so this was a good opportunity to see one again.

This is Not a Canberra or a Lightning!

The name English Electric is well known in aviation circles. Before it was subsumed into the British Aircraft Corporation, it had produced the Lightning interceptor and the Canberra bomber. The Lightning might have got more glory, but the Canberra was by far the more successful type with excellent performance. However, there is a lesser-known type that came from the company a long time before.

I first heard of the Wren when I read about it in Roly Beamont’s book. He was the chief test pilot at English Electric, and he described this vintage aircraft with very limited power that the company restored and hopped along the runway at Warton many years before I worked there. The aircraft now lives at Old Warden and it was brought out to fly during the Shuttleworth Festival of Flight. It was towed up to the far end of the field in preparation for its flight. The conditions were smooth, so it was going to be able to perform.

Having read that it was not over-endowed with power and that the Warton tests had involved some basic hops along the runway, this was what I had anticipated would be the case here. However, they were more ambitious. After flying the length of the field, a turn was made for a return run. I have to admit, when I first saw the turn, I did fear that all was not well. The whole flight was at low level, so the turn was also low. The angle made it look like the plane was heading for the trees. However, this was quite normal and in control. Even so, every turn made me tense up slightly. I guess by the end of the flight, I was getting used to it. Even so, it was quite unlike most flying I have watched.

Multiple passes were made during the flight. The light was definitely playing ball along certain parts of the passes so I was able to grab quite a few shots. It’s not the most elegant looking plane and I imagine the view for the pilot is pretty minimal. Even so, as rarities go, it is right up there so to see it fly was a nice result.

50 Years of Popham

This aviation moment was a bit of a last-minute thing. We don’t live terribly far from Popham’s airfield, and I have driven past it more time than I can recall including when travelling to visit family in Andover before we ended up living in Hampshire. However, I had never actually been to the airfield before. I had seen that they were having a celebration of the fiftieth anniversary of the first use of the field, but I did have other stuff going on at home. When I had finished that, I knew I needed to get a bike ride in as part of my ongoing (if feeble) preparation for the charity ride I had coming up. I decided to ride up to Popham and back and swing by the fly in.

The weather was really nice and there seemed to be a ton of planes that had made the trip in to join the celebrations. The road into the airfield goes right under the western approach end and I did stop there on my bike for a while to watch the arriving and departing planes. Then I rode into the airfield itself and had a brief wander around. There were plenty of people out walking amongst the parked planes and, if I hadn’t been in cycling shoes and pushing the bike, I would have had a longer time exploring. Instead, it was a brief stopover before continuing my ride. I hope they had a successful day.

Reinforcement Around a Cargo Door

The Vickers Vanguard might not have had the sales success of its predecessor, the Viscount, but a number of the passenger planes had a long career as a result of conversion to the Merchantman freighter configuration. One of these is on display at the Brooklands Museum. Since the cargo door was not an original design feature, the fuselage needed to be reinforced to accommodate the stress redistribution around the door aperture.

Since this was a retrofit, it was far simpler to have the reinforcement on the outside of the fuselage. Looking closely at the example at the museum, you can see the multiple layers of reinforcement to build up the thickness in the areas with the greatest stress increase. There were about ten layers in total with them tapering out as you got further from the opening. This was all prior to the days of finite element analysis so would have involved a lot of hand calculations!

Tanking Typhoons

I had the good fortune to be able to spend a day with 101 Sqn of the Royal Air Force when they were undertaking training missions in one of their primary roles of aerial refuelling. Based at RAF Brize Norton, the squadron operates the Airbus Voyager, the A330MRTT aircraft. The aircraft we were in was configured for two-point refuelling while some of the aircraft have a three-point config that allows tanking of heavy aircraft from the higher capacity centreline hose drum unit.

We took off from Brize and headed out over the North Sea. Our initial tracks were off the coast of East Anglia which made for a convenient place to pick up trade from the RAF bases there. The F-35s were deployed from Marham so there was less likelihood of one of those jets showing up, but we did expect Typhoons. It was too long after we were on station before the first customers showed up.

The jets appeared from the port side of the jet and picking them up early allowed you to see them sweeping in astern of the plane before they approached from astern. They would gather off the port wing extending the refuelling probe before being cleared into pre-contact positions on either wing. Then they would pull forward to make contact and take on fuel. Once they were done, they would gather off the starboard wing until the flight had all taken on fuel at which point they would accelerate away to continue with their flight. This departure might just be peeling away but it sometimes included a burst of power and a climb up away from our flight level with the noise even being noticeable inside our insulated cabin.

There are very limited options when it comes to photographing the jets while they are plugged in. The pods are mounted outboard on the wings – I think in the location where the outboard engines would be on an A340 – but the length of the hose means that the drogue is quite a long way aft. This means that only the last few rows of the aircraft – it has a pretty standard seating config throughout most of the fuselage – actually have the ability to see the jets. I had been advised by a friend that the viewing was limited.

I had brought two cameras on the flight. My main camera was fitted with the 100-400 lens and my use for that was on aircraft off to either side. The other body I brought along was an older one I use less frequently these days and that is the M6 with a 55-200 lens. This ended up getting a lot of use. However, neither of them was suitable for use when the jets were refuelling. The angles looking back are tight and the interior panelling around the window apertures limits how you can point backwards. In this case, the phone was by far the best option. The small lens diameter combined with the ability to get it close to the window meant it was the best bet. Even then, it was limited in what it could see.

Later in the mission we headed up towards Scotland to pick up some local trade although, ironically, we ended up with jets from Coningsby which would probably have been fine in our original tracks. Overall, the mission last over 6 hours and we had a variety of periods when we had customers and then periods of waiting. It was definitely an interesting day out and certainly worth seeing. My thanks to the team at Brize for hosting us so well.

The Atlantique is a Great Throwback

Leave a Reply

RIAT provided many high points for me this year. One of the types I haven’t seen for a long time was the Atlantique operated by the French Navy. I think I last saw one at Mildenhall at an Air Fete at the beginning of the 90s. Not only was the plane on the ground but it was also taking part in the flying display. Powered by a pair of Tyne turboprops, the engine whine on the ground is quite painful. You do need to give your ears some protection to avoid it getting too much. Once those engines are ramped up to take off power, the humid conditions meant some nice prop vortices showed up.

The display consisted of a number of passes. There is a radar installation that retracts into the fuselage for take off and landing as well as when it isn’t needed and drag reduction is more valuable. For some of the passes this radar was extended. Also, there is a large underfuselage weapons bay and the doors to this were opened to reveal a captive Exocet missile. The Exocet is a large weapon, and you really appreciate that when it is shown against a plane as large as the Atlantique. The French Navy is planning on introducing a new type based on a Falcon business jet so the chances to see an Atlantique will be diminishing soon.

The Gloomy Conditions Make the Cockpit Displays Visible

Back on one of my last visits to Coupeville to watch the Growlers undertaking FCLP, the weather was not playing ball and things ended up getting quite gloomy at the end of the slots they had planned. With a modern camera, this is not really an issue as you can handle some really low light without too much compromise. However, the thing I did notice as I was going through the images was that the green colours of the cockpit displays really start to show up. In some of the earlier shots, the light in the sky was reflecting off the canopy which washed it out a touch but by the last few passes, the green was really showing up.

Reverse Thrust Bizjets

Boeing Field is busy with business jets and some of them are more interesting than others. However, one thing that does catch my attention is the use of reverse thrust. On bizjets, it is often used for braking when taxiing to keep the brakes cooler. Of course, it is used for landings. Usually, the reversers are stowed as the jet slows but other times they are left in until they have vacated the runway. Here is a selection of jets with their reversers in use.

Take a Look at That Wing Span

Leave a Reply

Back around 1990, I saw an Antonov AN-72 at the Farnborough show. This was the time as the wall came down and eastern bloc aircraft started to appear at shows. After that, I don’t think I saw one again. That changed at RIAT this year when the Egyptian Air Force brought an AN-74 – an updated version of the original Coaler. The feature of this plane that gets lots of attention is the location of the engines. They are mounted above the wing and employ upper surface blowing. The exhaust from the engines is entrained but the upper surface of the wing which increases the lift and reduces approach and take off speed.

However, the thing I had never appreciated before seeing the plane at Fairford was the span of the wing on this plane. When it taxied in towards us, I got a view of it head on which showed just how large the span is. It is massive. The upper surface blowing only impacts close to the engines, so the rest of the wing is not affected. I wonder how much it matters. It was interesting when it took off at the end of the show that the takeoff run seemed quite long. It didn’t seem like a STOL aircraft. Anyway, forget all that and look at this amazing wingspan!

Catching an Evolution in the Gloom

Leave a Reply

The Lancair Evolution is not a particularly common aircraft although I have come across examples over the years. However, one slightly gloomy Sunday afternoon, I saw that one was heading to Paine Field. I understand that it might be locally based but I hadn’t seen it before and, with not a lot else going on, made the short trip up to Everett. On jaunts like this, you start persuading yourself that the clouds are going to part at just the right moment and then the sun will illuminate your subject against a dark and foreboding sky.

That has worked for me on occasion but this was not such an occasion. The conditions were still pretty dull when they showed up on approach. As is often my technique in these conditions, I shot quite heavily over-exposed. This allows for lots of detail in the aircraft to be captured and then for some masking of the background to bring it back down to something resembling what it actually was on the day. The eye does such a good job of dealing with dynamic range that it is amazing to see just how badly the exposures can vary in conditions like this. Getting the most of the data from the initial image and then letting the post processing techniques bring it back to what you actually saw is the way I like to go. This plane flew quite a bit after this day but never when I had a chance to catch it again so no sunny shots of it I’m afraid.
