Interesting Raptor Control Inputs

It might be a long time ago that I did anything closely related to the engineering of fighters but there is still a part of me that is a stability and control type of guy. Watching the control inputs and responses of planes is cool as far as I am concerned. With the advent of fly by wire designs, there was considerable scope to play around with the use of the control surfaces to achieve different aims. With no direct linkages to the stick, the pilot can be totally unaware of the choices the system is making for control combinations.

The engineers may have chosen to program the trailing edges to have different deflections inboard and outboard to offload the outer portion of the wing for example. The F-22 makes use of a variety of interesting control inputs. For example, it doesn’t have a traditional speed brake. I assume this was removed for stealth reasons. Instead, the control surfaces move counter to each other. You may have inboard flaps going down and outboard flaps going up. The moments cancel out but all increase drag incrementally so the effect is like having a speed brake deployed.

Since the aircraft is also unstable, you may have tail deflections that seem at odds with the maneuver being flown. During the Chino show, the usual routine was flown (usual for an F-22 but not many other jets) and, as I look through a bunch of the shots, I see some quite unusual control inputs. If you are in to such things, these may appeal to you. Gary, are you reading this?

Some Gratuitous Raptor Shots

Unfortunately, I have a rather large backlog of images that I haven’t done much with. This is sometimes the result of having a number of events in a short space of time and other times it is the result of laziness! Last year I covered the Planes of Fame show at Chino for GAR. I got a lot of shots while I was there and I needed a selection to illustrate the piece so I dived in, found some good examples, worked on those and put them into the feature.

Unfortunately, I never got around to undertaking a proper run through of the shoot. I only realized this recently so I have started to go through the images when the time allows. One part of the show I really liked was the twilight show on the Friday. This included a display by the USAF F-22. In the last light of the day, the airframe looked really great.

Running through the shots I found a few of the jet that I really liked. (I found more than will work for this post and some that I like for various reasons but won’t really gel with most people.) As a result, here are a sample of the shots I have been finding. Now I am starting to think about air shows this year for the first time. I might have to go to this one again!

Parade of Ships

I have mentioned the LCS ship that was part of the Parade of Ships for Fleet Week. It was one of several warships to take part in the parade. Most were US Navy ships but there was also a Coast Guard ship and a visitor from the Royal Canadian Navy. They entered the bay under the Golden Gate Bridge before parading in front of the spectators arrayed along the shore and in the boats out on the water. The first ship was led by a fire boat that sprayed water from its cannons in greeting.

These pictures are a sample of the different ships that were on parade. Another warship was part of Fleet Week but it remained tied up during the parade which was a shame as I would liked to have seen it. You could tour it if you wanted but I had other plans that meant that wouldn’t work out.

Tucanos Low Level (But I’m Not Prepared)

The Lake District is an area that is known to be popular for low flying military aircraft. In all of the years I have been going there, I have hardly seen any jets coming through. Mainly that was because I was there at the weekend and the military don’t tend to fly much at the weekend. I was hopeful that we might see some traffic on this trip since we would be there midweek. We did get some traffic but it didn’t go quite as planned.

A few times we saw Hawks zipping over the town while we were outside. We were generally getting ready to go somewhere else and they caught me out as they came through. On one hike I took a long lens with me. Of course, this didn’t go to plan. Most of the time I was looking at some lovely scenery so I had a wide lens on the camera. This was the time the RAF chose to show up. No jets this time but a selection of Tucano turboprop trainers. I wasn’t expecting them when they came through so grabbed the camera with the lens I had on at the time and got a few shots. These won’t be of much use to me but they do remind me of the excitement of being caught out be a low flying plane of any type.

USS Coronado LCS

As a small boy, my Gran would take me to Portsmouth each August for Navy Day. We would spend a day walking around the dockyard and getting on to various warships to see what they were like. This was a pretty big event and, in those days, the number of ships in port for those days is probably more than the Royal Navy has in total today. The result of this was an interest in an early day with warships. Growing up by the water meant that ships of all types were a regular feature of life.

Warship design underwent quite a transition. Traditionally, warships had been slender designs that achieved speed and supposedly provided the most stable ride. However, this was not an approach that was universally agreed and shorter broader designs started to gain favor. The Royal Navy’s Type 23 frigates were one of the first signs that Navy’s were taking new configurations seriously.

The US Navy’s Littoral Combat Ship (LCS) program has gone a stage further with one of the builders. There are two LCS designs in production and one of them has a narrow center hull and two additional outboard hulls further aft. This trimaran configuration provides slender hulls but with a lot of stability and the space for a large deck. One of the LCS ships was in San Francisco for Fleet Week and took part in the Parade of Ships.

USS Coronado (LCS-4) was the ship on display. She is the second of the General Dynamics – Bath Iron Works ships to be commissioned and entered service in 2014. As she entered the bay under the bridge she turned towards to city and you could get a good view (albeit at some distance) of the unusual hull shape. As she got closer, the view was more abeam the ship but you could still see the layout of the armaments. As she headed away, a view of the stern hinted at the hull layout but really emphasized the width of the deck.

The US Navy is currently reconsidering its needs and is looking for a frigate that is more heavily armed than the LCS designs but makes as much use of the hull designs as possible. We shall see how that all works out. In the meantime, this is one of the more unusual shapes afloat. The Zumwalt destroyer is even more unusual so I shall have to try and see that at some point too.

Wall of Fire Take Two

While I was walking around the display line of the Airshow of the Cascades during the evening show, the Erickson collection’s P-38 was carrying out its display. I was in amongst a lot of people when the announcer told everyone to be ready for a special pass. My location was not great but I got ready as the P-38 ran in for a topside pass expecting the detonation of some pyrotechnics behind it. Nothing happened. The P-38 flew by and no explosions.

A short while later, the announcer had a second crack at getting us ready for the pass. Obviously the first pass had not worked as planned. This time the P-38 was coming in from the opposite direction. I also had a few moments to try and reposition myself to get a better view. This shot was the result. Some of my friends were further up the display line and got a different angle on the shot which was cool. Even so, I am pretty happy with this.

Erickson Aircraft Collection

I attended a course recently that was held in Madras OR at the home of the Erickson Air Museum. This museum is a fantastic collection of vintage aircraft, some of which were used for the course, more of which will appear on this blog in due course. At various times while we were there, I had the opportunity to wander around the museum and see the collection. This included during the evening when a party was underway but which also meant they had some interesting illumination.

The majority of the aircraft are warbirds but not all of them. A Bellanca was present which is, to be generous, a most unusual looking aircraft. I would certainly have liked to have seen it outside had the opportunity arisen but that wasn’t to be. There was also a Martin Mauler which is an aircraft I had never heard of previously. It looks like a Skyraider but you could tell it was different. It was just hard to know what it was without checking the information on the display.

Madras is not on the trail for most people so I imagine the museum does not have a lot of people happening upon it. However, it is a nice facility with a great collection and a super bunch of people working there. If you like warbirds and vintage aircraft, it should definitely be visited at some point.

Sneak Pass

Leave a Reply

I have seen a large number of displays by the Blue Angels over the years. Their display is a good one generally (although the ground portion is a little time consuming in my opinion). The sequence does not vary much from year to year but it works well enough so that is probably no big surprise. One of the fun parts is the sneak passes. The four ship head off in one direction to distract you and a solo jet streaks in from the left at low level and high speed. This catches a lot of people by surprise.

Just as everyone is getting over this, the other solo jet does something similar from crowd rear to make you all jump again. The displays that are held over water provide an added option for the first sneak pass. With no obstacles, the aircraft can end up very close to the water. This makes things look even more impressive. Also, the high speeds can result in some impressive vapor formations in the shock waves.

The Fleet Week display on the Friday had great weather conditions but, surprisingly for the Bay Area, the humidity levels were not terribly high. Consequently, while the sneak pass had its usual surprise impact, it did not result in any vapor on the jet. The upside of this was that the optical distortion caused by the shock waves was visible in some shots when a reasonable amount of background was included. Not what I was aiming for but not a bad alternative.

PBY

I’m not sure when I first became aware of the PBY Catalina but I am pretty sure it involved a plastic model that a friend of mine had. (Kev Fry, was it you?) Flying boats always appealed to me and the blisters on the rear fuselage caught my eye even at that time. Erickson has a PBY in the collection and it was going to feature in our program. However, my first encounter with it was as it was parked up on the ramp outside the hangar.

I was walking around in the early evening light and the paint scheme seemed to glow in the low sun. It is a big beast so there are lots of options as you walk around it. Whatever shot you want to get, you do want something that emphasizes the hull shape since that is one of the defining characteristics of the plane. Sometimes, getting in really close can achieve that.

You do want to check out multiple angles, though. Whether it is the nose shape, the wheels and wheelwells or the rear blisters, there is something from any direction worthy of a look. Whether they will all be great shots is a different story. However, having the chance to shoot one when hardly anyone is around is a chance not to be passed on.

Air Force One

I have had a pretty poor run of luck when it comes to Air Force One. I have seen it overflying in the distance, I have seen the VC-25 on the ramp at Davis Monthan but was thirty seconds from being parked when it took off and I had a failed effort to get it at SFO which I mentioned in this previous post. It was back in San Francisco recently and I decided I was going to have another go.

I tracked the TFR online and, this time, it didn’t change. I, therefore, got to SFO with plenty of time before the departure. The weather was not fantastic but there was generally a clear spot over the airport so I was a little optimistic. As the intended time for departure approached, the cloud rolled in. Of course it did! Nothing I could do about that. Meanwhile, departures off 01 had stopped (I am not sure whether that was related to the Fleet Week air show or not) and a bunch of planes were lined up to depart from 28. Then they all stopped.

I assume the President had come by road as there was no helicopter activity other than a police chopper over the highway. The beacons were on as I heard the sound of a jet going around. It briefly appeared through a gap in the clouds and was a United 737. I guess they had just timed it wrong. I have no idea whether they held or diverted. Suddenly the VC-25 was rolling. It taxied rapidly along the northern taxiway by 28R with a couple of Secret Service vehicles following close behind. Without a pause it turned onto 28R past the waiting airliners and powered away. The Secret Service chased it for a while down the runway but it was airborne pretty swiftly. I guess it was lightly loaded. A few minutes later everything started moving again. Another ten minutes and the sun was out. Typical!
