    Lukps, as usual you are getting confused. Fish eye from DDM-NG has a plane array.
    Curved IRST could match the curvature of a plane, but NVM

    The rest of your assertion is also false. The fact remains that DDM-NG doesn’t have the ability to do anything other than missile warning right now and the Rafale has no HMD, so it would be much more difficult to usefully present and action the information even if it did.

    Nope, again. (fisherman’s tale of course)

    Dont you think K226 is a bad choice for supply and rescue in high altitude considering its lower rotor being so low slung(just like KA 26). It could hit people when landing on cliffs on uneven positions. Also getting out from Kamov when it is powering down on ground would be a risky proposition.

    but then again it could be just me, and the above fears could be unfounded.

    TBH i think they are unfounded. Training crews should avoid such accidents.

    :confused: What is “unstealthy IR sensor” and how is the “stealthy one” different?

    Ask high priest Lukos of the Typhoon-F35 church.

    These planes are fine, np with it, but not almighty.

    The point is that I have.. And it doesn’t look too good for EODAS which is 640×480 25um pitch sensor.
    I won’t mention the DDM-NG because I was unable to find it on public domain and cannot assess the classification of such piece of information.

    Anyway, I cannot see how the DDM-NG “is not programmed with the sensitivity” to filter out false alarms or has a back-end with less computing power if it’s de facto more modern and uses newer technology than EODAS.

    Just ignore it..He is in his troll mode atm 😉

    Just half trolling. Onera recently developed technology for curved IR arrays 😉

    Cross Posting from the Eurofighter Typhoon thread

    It does a lot more as has been presented here before including the original patents from Westinghouse. It was always meant to have a track capability right from the time when the concept was developed.

    It is obviously not an EOTS on steroids with 360 degree coverage but a bit different. It won’t have the range of the EOTS when it comes to positively Identifying targets in the fighter signature profile..but that was never the intention..The plan was to have something that could find targets for the EOTS to take over, or at shorter ranges (compared to the EOTS) do these sorts of things independently. It was also a plan to have a target ID’d through multiple sensors and then handed off to EODAS for tracking. Its an algorithmic function where you can either ID and track by yourself (just the DAS) or through a combination of sensors including multiple EODAS sensors.The concept basically was to have it be universal (all F-35’s) 360 degree system through which aircraft could create a large area of constant IR coverage..You position your 4 ship in such a way to maximize IR, and RF coverage (both active and passive). I’ve posted details on the original patents and lots of information on it both from a concept to how it is implemented. The idea is/was to develop multiple sensor tracks from both onboard and off board sensors and this would be accomplished through aircraft flying apart, at different altitudes covering a very large battle-space.

    From Pre F-35 days (JSF competition)

    JDW, 2000

    The DAS is comprised of 6 staring focal plane arrays which gather midwave IR photons throughout the entire sphere surrounding the aircraft. The DAS performs these functions: short range IR search and track, missile launch detection, point of origin of missile launch, and navigation imaging. The pilot may use these cameras to “look through” aircraft structure. DAS imagery is displayed both head down on the PCD as well as head up on the HMD.

    The AN/AAQ-37 was used for the MDA mission test because it already had the algorithms, software and the computing developed to detect and place in track the ballistic missile from launch. The Ballistic Missile target was placed in a track after identifying it approximately 15 seconds after launch at those long ranges. The implications are obviously significant for a potential high loiter UAV that can cover a massive amount of airspace through its IR sensors and communicate launch information through SATCOM in addition to providing a spherical IR SA to all friendly assets.

    May be ask ONERA to help with curved IR sensors?

    A rocket exhaust is not a star. Already explained this. DDM-NG doesn’t track aircraft, it’s MWS only.

    nope

    An ICBM exhaust is not a star, and is neither star-like in size nor brightness, unless the warheads go off. The human eye certainly can’t see rocket launches at 800nmi, nor can they see stars in the day time, nor continue to track a rocket even after burn-out based purely on residual heat. Nor do they see infra-red, which explains why their distance detection of hot objects is nowhere near as good.

    Now you’re bring ID into it, which isn’t the same as detection, and that’s where telescopic optics are useful. But for mere detection and location, highly sensitive sensor apertures and processing are sufficient.

    Surface temp of the sun is about 5800 Kelvin. No idea of the exhaust temp of this missile.

    Does anyone know of an surplus phantom droptanks that are available in the UK, we are looking for a pair for our FG1.

    Better try in Germany? Their F4 were only recently decomissioned.

    Do we actually use Centimetres in industry ?
    I was at college when were in the process of changing over from Imperial to Metric measurements.
    We only referred to Metres and Millimetres.

    usually not, but his idea was to talk about metric system i guess. Usual units are M, mm and µm

    No, I do too but for some reason they have made the model with transparent sections which is why halloweene said it looked optionally manned.

    I think from what I have read, BAE are out of the MALE market (they think its too crowded to make any money in) but if the Europeans need some MALE UAVs then this project could be made to work.

    you ar probably right.

    Here’s a little bigger image from Alenia’s twitter.
    [ATTACH=CONFIG]237461[/ATTACH]

    It’s quite a bit different from Dassault’s MALE 2020 model from only last year.

    Bizarre… Looks as optinnaly manned.

    CAESAR was only one development vehicle for the technology, others like Bright Adder were also on the go. Selex UK were also developing other AESAs.

    Ha, so it’s 2025 now, even though no source gives a date that late? Between this and using 10 year old paragraphs on wikipedia to prove a point your bias is obvious. I note you didn’t even provide a link to wikipedia when you copied that paragraph, wonder why?:highly_amused: So where is your source for 2025?

    Not really, the UK armed forces blog suggests a two-phase update in 2017 and 2019, with it ready for order in 2015/2016. What’s to misinterpret?

    http://ukarmedforcescommentary.blogspot.co.uk/search/label/Bright%20Adder

    1+ will arrive in 2017 as the blog suggests, Mk2 will arrive in 2019, no back end difference between the two is mentioned and Mk2 will have electronic attack, long range NCTR and high speed comms, therefore they must both have an updated back end to allow for this expansion on the same architecture.

    My claims are sourced with up to date material, your only source is an old paragraph in wikipedia. You therefore continue to fail at rational debate.

    in 2013, they announced a quick release of P1EB, remind me when it was effective?

    Captor E isn’t anymore linked to P2E, it is a separate contract to STUDY its integration… (you so much like to stress that point about MELBAA study plan)

    I do wish Typhoon to get Captor in 2017 (dubious) afterall it is part of our common defence system. But i’m very doubtful abour Bright Adder program results being implemented in 2019. First you must debug the harware and software, check non regression etc. No pun intended.
