http://www.sldinfo.com/shaping-a-ne...ming-of-the-f-35b-to-the-new-british-carrier/Group Captain Townsend: The F-35 is not a multi-role fighter. Multi-role, in current thinking, would be a sequential series of tasks. The F-35 is doing a number of missions simultaneously. The concept of mission simultaneity is really important.
The airplane has the ability to do things without the pilot asking it to do it. Automatically conducting, particularly, ISR whilst it’s conducting an OCA mission or an attack mission in a very different way than platforms have done business in the past. This is something that other operators are working in the package alongside F-35 need to understand.
That the F-35 operator won’t be going through sequential thought process. He will be thinking about the battle space in a broader sense, a much different way than a Typhoon operator would be thinking about the battle space.
I think there is another step change and difference in the way in which the information is displayed to the pilot which is important and is extremely intuitive. I’ll give you an example. I commanded a Typhoon squadron for two years.
Very early on this job with F-35, I was lucky enough to fly the F-35 simulator. and the different way in which F35 displays information compared to Typhoon is eye-catching. In fact, I asked for the simulator to be stopped because I was taken aback by the information being displayed to me. There was just so much data available at my fingertips, but displayed in a really different sense in Typhoon.
So very, very quickly, I knew a great deal about the entity being targeted – sensor fusion at work. I think it’s a very different way of displaying information that any other fast jet has done before.
Knowing what my wingman is seeing and my wingman knowing what I am seeing, and my ability to communicate what I want to have achieved by my formation, by my package, which all may be by the air wing that’s air-borne at the time. This airplane changes the game in a way which we can conduct that sort of business.
Kertoisitko lisää tuosta 3. kohdasta. Missä harjoituksessa tätä on testattu Gripen E:llä, montako konetta harjoitukseen osallistui, moneenko lentosuoritteeseen Gripen E pystyi per päivä ja montako viikkoa harjoitusta jatkettiin?Onko allaolevissa jotain vialla?
1. Gripenin vahvuutena suhteessa F-35:een on avioniikka-arkkitehtuuri ja ohjelmisto-osaaminen. Gripen on näiden osalta selvästi uudempi tuote kuin F-35.
2. Gripenissä sensorifuusio on otettu huomioon suunnitelussa. Julkisten tietojen pohjalta on vaikea arvioida kummassa, Gripenissä vai F-35:ssä, on kehittyneempi sensorifuusio.
3. Gripenillä kyetään useisiin lentosuoritteisiin hajautetuissa oloissa usean viikon ajan. Kyetäänkö F-35:llä?
Niin, mutta missä määrin ruotsalaisten köyhyys, pitkä ostajattomuus ja hankkeen perustuminen entisen Gripenin rajoitteisiin on vaikuttanut?Gripen on kuitenkin huomattavasti uudempi tuote. Tietokoneohjelmatkin on kehittyneet huimasti vaikka 2018 vrt 2000.
https://sldinfo.com/2018/11/the-f-3...om-the-international-fighter-conference-2018/The F-35 and Data Fusion: A Perspective from the International Fighter Conference 2018
26 Nov 2018 Robbin Laird
"One of the presenters at the conference was an experienced F-16 pilot who had transitioned to the F-35 in 2010 and has spent several years as a USAF test pilot at Edwards Air Force base and more recently has joined Lockheed Martin in 2016 in a test pilot capacity at Edwards AFB. I had a chance to sit down and talk with Scott “Shark” McLaren about his experience with sensor fusion on the F-35 and his perception of the combat advantages which this provides the F-35 pilot.
The baseline point is that the designers of the F-35 cockpit based on their experiences with the F-16 and the F-22 worked to provide for a visual and work system that significantly reduced the pilot load. Then with the integrated sensor system built into the F-35 the role of data fusion is to provide situational awareness as a service to the pilot and the MADL linked combat force.
This is in contrast to a legacy fighter where the pilot is fusing the data up against a core task such as air superiority or ground attack. In contrast, the fusion system “engine” leaves the F-35 pilot with more flexibility to perform tasks as well as operate in the words of the USAF speaker in the first morning of the conference to provide for strategic inputs as well.... [Then follows a description of what an F-16 pilot must do which takes two years+ to master]
...“With the F-35, this is where the operational capability changes. “With the F-35 you have automation via fusion going on. “That process that is taking the F-16 pilot years to get good at, and almost all of a notional ten-minute engagement time to build a good picture, is being done automatically for the pilot in F-35 fusion.
“That picture is being built. In that same ten-minute scenario, it’s taking less than a minute for all of that information to be presented to him. “He knows the picture. “And that’s without any communication having to go across the formation.
“Your mental processing power which in the F-16 is focused on creating the operational mental picture or SA is now focused on combat tasks and missions. “Your training focus also changes. “Rather than focusing significant training time on how to shape your SA picture, you can now focus on tasks in the battlespace and distributed operations.
“The Commander and the F-35 force can focus on the effects they want to deliver in the battlespace, not just with themselves, but by empowering other combat assets as well by sharing the SA through targeting tasking. “We have the capacity to third party target and to distribute the effects desired in the battlespace. “That becomes our focus of training and of attention; not a primary focus on generating the SA for my organic asset to survive and to deliver a combat effect itself.
Using Shark’s 10 minute operating paradigm where the F-16 pilot is spending 8 minutes of that time period on SA and mission preparation, the F-35 pilot can spend 9 minutes of his time on mission preparation and distributed operations if so tasked. Shark concluded: “For the F-35 pilot, training will now need to include how you go out and influence the battle area the best for the commander?
“And that’s going translate up to what the commander needs to give in direction, but also back down to what the pilot needs to know. “And that training is part of a larger joint exercise, a larger concept of operations for the joint force which gets at the strategic impact of the F-35, which the USAF Brigadier General discussed in the conference.”..."
What 4++ gen (Rafale, EF Typhoon for example) sensor fusion does is:
1. Pilot operates and tasks the sensors how he sees fit.
2. Datalink shared tracks between fighters within seconds from commencing tracking and update interval is usually several seconds so accuracy is pretty poor for sensor fusion
3. Each sensor generate detections and correlates them to tracks inside the sensor. ID is done by individual sensors if possible.
4. Tracks from each sensor is sent to sensor fusion engine
5. Sensor fusion engine correlates tracks to single displayed track file.
6. Single track is displayed to pilot
5th gen sensor fusion works differently:
1. Sensor fusion engine tasks the sensors automatically
2. High-speed intra-flight datalinks (IFDL and MADL) share sensor data between aircraft very quickly and target data accuracy is very high and up-to-date.
2. Each sensor sends all the information they generate to sensor fusion engine after some preprocessing. Each sensor can still generate detections and tracks by themselves also if tasked by sensor fusion engine
3. Threat libraries and other such data are used by sensor fusion for example to ID targets from all the sensor data available
4. Sensor fusion engine generates detections from all the sensor data and correlates them to tracks
5. Single track is displayed to pilot
Rafale sensor fusion: when multiple sensor tracking/detecting targets, it only uses data from sensor with the highest amount of information and ignore everything else
Typhoon (Gripen E kai myös) sensor fusion: when multiple sensor tracking/detecting targets, all information from all sensors that is tracking that target will be used to get more accurate track
F-35 sensor fusion: when multiple sensor tracking/detecting targets, all information from all sensors that is tracking that target will be used to get more accurate track, also difference sensors can also communicate with each others to cue, rely track, when sensors detect something, it will ask others sensors to look at that direction for more information.
4Gen Teen Jet : around a dozen parameters to classify/identify a potential threat
F-22 : more than 200 parameters
F-35 : more than 600 parameters
