    Malaysian PM: Committed to justice for downing of MH-17

    Speaking in Berlin after meeting Chancellor Angela Merkel, [Najib] Razak says after Dutch authorities release the criminal investigation results, the countries involved will discuss the next course of action based upon the findings.

    He says “we remain committed to … bring those people responsible to justice.”

    rgr. But why fly so low decomissionized planes roasting in the desert? IMOHO, anybody would be happy to have a bit of clear airspace under the plane. πŸ˜‰

    Test for the Laser fitted A60? (twin EO sensor + central turret)

    Perhaps an homeland security fighter with AiM9X II (ER) for the ones that are truely supersonic.

    Thanks for the link b/w.

    Seems to suggest a higher empty weight than expected but 14,000lb did seem a little silly. Maybe they meant ~14,000kg.

    We have also the CG location (35% MAC) at 0% offset πŸ˜‰

    They probably need stealthy airframes to test radars/countermeasure systems on.

    Nic

    It looks like more a buddy UCAV test. There are no reason otherwise to fly that close in a stealth aircraft.
    Perhaps a test for the Raider or future 6th Gen optionally manned aircraft?

    Tamarack Aerospace Group pitches winglets for C-130

    According to Mitchell, the winglets developed by Tamarack Aerospace Group differ from those developed elsewhere to reduce wing loading also, and thereby increase the wing’s service life. “We have patented a load alleviation device that ‘aerodynamically turns off the winglets’ during those rare moments when ‘g’ forces are high. The system is constantly monitoring and predicting gusts and/or manoeuvres, and ‘positions’ the Tamarack Active Camber Surface (TACS) as necessary to eliminate the additional loads that a static winglet would normally affect.

    That’s really good.

    From Tamarack website:

    The active surfaces on the wing extensions that look like little ailerons are called TACS. The TACS move up and down to alleviate certain loads on the wing that otherwise would be addressed by adding extra structure (weight) to the wing. Together, the TACS, extension and winglet compose the ATLASβ„’ Active Winglet system.

    But perhaps LM will come with its own integrated system.

    The IRST can/might use Luneburg effect to hide it’s shape.

    We.have been already discussing that and I think the answer was already given.

    Yes. Of course but he was mentioning relative precision.

    If e is the precision over A then e will be also the precision over A/10 (sensor characteristic)

    Let’s say that e/A=r then e/(A/10)=10*(e/A)=10r
    Relatively,the precision affects 10 times more a measured distance at 1/10th the range.

    @ Garry, regarding your first question on your last post:

    The precision is independent of the distance. Hence when evaluating a closer signal return, the inaccuracy will be relatively higher in percentage than for a farther one (sin, cos and tan are evaluated distance).

    Extended footage of the Boeing presentation video:

    I noticed:
    . – the main gear door prevent a volume expansion of the inlets downward refraining future possibility for a modified/ swapped engines)
    . – the long hinge used for the canopy looks frail for 40+ year of usage (but what we see could be simply a protective cover over multiple smaller hinges).
    . – fowler flap (?)
