The X-35B and Its Propulsion System

The F-35 is in widespread service in considerable numbers with many more to come in due course. However, before the F-35, there was the X-35 – the Lockheed Martin contender in the JSF competitive fly off. Up against the Boeing X-32, two X-35s were built. One of them was initially used to demonstrate the proposed Air Force configuration before it was modified with the vertical lift system proposed for what became the F-35B in USMC service.

With the competition complete, the demonstrators were superfluous and the X-35B airframe made its way to the National Air and Space Museum. Here it sits on display. What is the most interesting part – at least to me – is that they have taken the propulsion system out of the jet and put it on display separately. You can see the main engine as well as the lift fan module, the shaft coupling the two, the nizzle that both have to direct the flow and the roll posts that are used to provide both additional lift and roll control in the hover.

It is a cool demonstration of the basic configuration that is now operational in the F-35B. it has certainly been developed since this design, but the basic principles remain the same. Unlike the Harrier that had the engine in the centre of gravity of the aircraft (not a very convenient location) and redirected all thrust through four nozzles, this configuration has a mighty engine at the rear which can be vectored down when required through a three bearing nozzle that is both simple and ingenious but then a shaft drive from the same engine to a fan module that sits behind the cockpit drawing air from above and directing it down with some ability to vector it too. This forward fan balances against the rear main nozzle. It provides a significantly higher amount of vertical thrust than the Harrier ever managed and allows a larger and more capable aircraft to land vertically at the end of missions. Quite a smart piece of design.

Holding Down the Swordfish

During the Cosford air show, the Royal Navy Swordfish was part of the display. While it might not be the fastest aircraft from that era, it still has a pretty meaty engine up front. Once started, time is needed to get the oil up to temperature and to run up the engine to check its performance before it goes flying. The ground crew needed to keep the plane anchored while this was done and the way they did this was to hang on to the tailplane. Watching them getting battered by the prop wash while the engine was cycled was rather amusing.

Naval Wildcat Being Thrown Around

I shared some images of the Royal Navy’s Wildcat in formation with the Swordfish. The Wildcat also did some solo demonstration manoeuvres and, while the lighting was still a bit difficult, I quite liked some of the angles it was possible to get on the airframe. While the Wildcat is quite an evolution of the original Lynx, it is nice to see that it still has the agility that the Lynx was renowned for.

Photographing a helicopter, I am looking for a more dynamic angle on the airframe. Their ability to keep the speed low and have things close to the crowd line means you can get head on shots, underside shots and topside shots as they throw the helicopter around. The topside is the one I want the most. Things went pretty well and I am overall quite happy with the results. Oh, to have something like this on a summer evening with the light behind me.

Tiger Moth is Perfect for a Sunny Day

I recently shared some images of a Spitfire two-seater that was providing rides at Compton Abbas when we visited. It wasn’t the only plane providing rides (although it was definitely the most expensive). There was also a de Havilland Tiger Moth taking people up. I might not have quite the nostalgia that some have for old de Havilland types (let’s leave the Dragon Rapide out of the conversation at this point), but I have developed more of an interest in older types as I have similarly become an older type myself.

I did wonder whether the gusty conditions might make it a bit difficult for a tail dragger but they seemed to be coping just fine. It did look in fine condition and had a more sedate pace that didn’t test my panning skills quite as much as the Spit. I have had a flight in a Tiger Moth once in my life and that came courtesy of my friend Eric. I know how much I enjoyed that and I imagine that the passengers at Compton Abbas had a great time too.

The Tutor is Going

It seems that equipping display teams is becoming rather difficult for some countries. The RAF has taken the Red Arrows down to seven jets because of engine issues and a replacement has not yet been selected. Meanwhile, the RCAF has selected the PC-21 to replace the Tutor with the Snowbirds, but they won’t arrive for a while. In the interim, the Tutor is being retired so there will be a hiatus for the team.

The Tutor was a strange little jet. Looking a bit like a Jet Provost but with a bit more oomph, the RCAF retired it from training duties a long time ago but kept a bunch of them running just to support the Snowbirds. I have seen them display on multiple occasions and really enjoy the display. The team also were a lot of fun when I got to spend time with them in Waukegan for the show there. Moose Milk is dangerous stuff.

This year is the last year that they have displayed with the Tutor and, since we have been gone for a while now, I didn’t get to see their last shows. My last year of seeing them display was filled with difficulties either with aircrew that had been injured or with unserviceability. In one show a jet went down and the pilot ran to a backup jet but couldn’t get that one to work either. I guess that was a sign of just how much the fleet was aging. Oh well, farewell Tutor. I hope I get to see the display with the PC-21 at some point.

Won’t Forget the Blue Angels Crosses Too

I posted a bunch of crossing shots of the USAF Thunderbirds and, since I was doing that, I thought it might look like favouritism if I didn’t do the same for the Blue Angels. I saw a lot more of the Blue Angels in the second half of my time living in the US because Fleet Week in San Francisco and Seafair in Seattle always had them in attendance. That meant I got to see them after the transition to the Super Bug but the majority of shows I saw over the years were with the legacy Hornets. Anyway, here are a bunch of crossing shots for the Blues to balance things up.

Blue Eagles Return

One of the teams taking part at the show at Cosford was the Blue Eagles. The Army Air Corps used to have a team called the Blue Eagles and I saw them on a number of occasions but, apparently, the name went away for a while. It has returned and the routine is a combination of a pair of Apaches and a single Wildcat. This was my first time seeing an Army Wildcat display and that might not happen much more since the recent defence review announced the=at they would be phased out.

The coordinated manoeuvres of the two Apaches combined with the Wildcat doing its own thing. It kept something in front of the crowd at all times. The Apache is such an impressive machine with a menacing air about it. Meanwhile, the Wildcat has inherited the agility of the Lynx and so was thrown around with some vigour. I was happy to watch them perform and liked the synchronisation that they put into the planning. It is a good demo of the Army’s aviation capabilities.

Old Wessex but They Still Look Good

When I was first seriously into aviation, the Wessex was in widespread use with the UK armed forces. The Navy had a load of them while the RAF used them for both troop transport and for search and rescue. The Sea King was in production and was gradually taking over the roles. As a fan of anything new at the time, I viewed the Wessex as rather old and uninteresting. The new Sea Kings were far more appealing to me at the time.

Two things have changed my perspective. First, I have grown to appreciate a load of stuff over the years that I didn’t care too much about when younger. Also, having had the fun opportunity of spending a load of time with Midwest Helicopters and their S-58Ts when living in Chicago, it reignited my interest in the type. I think Historic Helicopters have an operating Wessex, but I haven’t seen that myself. However, Cosford had a couple of examples on display – one in SAR yellow and one in camo. They looked immaculate and it was great to see them on the ramp looking just as if they could be ready to head out on a mission as soon as the show wrapped.

Thunderbirds Crossing Shots

Leave a Reply

As is often the case, I was looking for something when I came across something totally different and that took me down a rabbit hole. In this case, I found myself looking through some old shots of the USAF Thunderbirds. Particularly when living in the Midwest, I used to see them display pretty frequently. You get a bit blasé about it after a while. Anyway, I was skimming through shots to see whether I had any crossing shots that I liked. I was pleasantly surprised to find a few of them that came out pretty well. Modern cameras allow rapid frame rates which help with crossing shots but apparently, I could still get it right occasionally when the tech wasn’t quite so advanced. The weather and lighting might vary a bit but here are some of the ones I liked most.

Want a Ride in a Spitfire

Leave a Reply

Two seat Spitfires seem to be ten a penny these days. The ability to make some decent money providing rides for people is a good way of supporting more airframes which isn’t a bad thing, even if they don’t look quite as elegant as the original design. There was one at Compton Abbas on the day of our visit that was doing a pretty good business taking people up for a ride. A blast down to the south coast and back seemed to be the norm.

You had plenty of notice when it was going up. The process of strapping in the passenger was not speedy and, while the pilot might not yet have come out to pre-flight, the activity loading up let you know that a flight was not far off.

Conditions were pretty blowy which, given the location on a hilltop, didn’t seem so surprising. I wondered whether this would limit flying but it didn’t seem to be much of an issue. Besides, the wind was quite close to being down the runway so not much of a challenge. When firing up the Merlin, the crowds outside the restaurant were treated to a blast of wind from the prop. A few hats would be dislodged but no one seemed to mind!

There were quite a few flights during the course of the time that we were there. The return at the end of each flight included a high-level flyby but no beating up the field I’m afraid. That would have been a nice way to round things off but maybe that would not go down well with either the CAA or the neighbours.
