    It was a Mi-17 and it was not "soviet-made". "Russian-made" would be better. The Mi-8 was "soviet-made".

    Many Mi-17s were Soviet-made.. The Mi-8MT(MTV) was introduced in 1977, first Mi-17s were exported in 1981.

    IF Wikipedia is right you are correct since the Mi-17 in question was purchased in 1997 from Russia. Former Hips(Mi-8) were purchased from Soviet Union in late 70´s.

    That's funny because "Mi-17" was the export designation of the "Mi-8MT", produced from the late 70s.

    I'm puzzled why Russia never sold Syria Mi-28s. Seems just what they need against ISIS.

    Money, plus it would be blatant open support (which so far has been fairly low profile if extensive). With brand new Mi-28s you can't claim Soviet era deliveries.

    Syria ordered Yak-130s and MiG-29s a while ago, and those contracts have been frozen as well. Meanwhile the "Syrian Express" comes into Tartus monthly.

    There is production constraints. Iraq is more important due to protection of Oil. i think if Iran gets money. there is big opportunity for Russian weopon sales to Syria.
    infact lower oil prices will make even the rich arab poor that they will only afford Russian weopons to fight endless wars.

    US Army to acquire enhanced MH-47G Block 2 Chinooks

    he US Army Aviation Integration Directorate is proposing the resumption of production after this date to deliver an undisclosed number of additional MH-47G helicopters in a Block 2 configuration
    [...]
    One option being proposed by the company is the Advanced Chinook Rotor Blade (ACRB). Still under development, the ACRB is not a flat blade* as currency fitted, but features lots of geometry and a new asymmetric aerofoil to increase the lift by approximately 900 kg per blade (5,400 kg for the helicopter). An interesting design criterion of this blade is that the first 45 cm, where it attaches to the hub, is identical to the old blade for easy retrofit (the ACRB is also made of the same materials as the old blade). Boeing said that the ACRB should be ready for fielding in about 2019, raising the baseline CH-47F helicopter's current payload from 10,886 kg to 16,286 kg
    The ACRB system:

    *I assume symetrical airfoil is what has to be read.

    Those numbers seem incredible. I also question that payload capacity could be increased by 50% without implications for the airframe.
    Brief and powerless is Man's life; on him and all his race the slow sure doom falls pitiless and dark.

    No. The early CH47 had a Naca 4 digit sym airfoil (0012) like many rotorcraft. Commonality, pattern of employment and simplification in growth (huge increase in payload - I think it's the F model that could lift its A ancestor) have led to only minor modification of the rotor blade sections like in many other helicopters.

    Please find below an illustration of CL comparison with a more modern airfoil from Boeing Vertol with the same characteristics (thickness 12%):





    As you can see, there are some huge difference that makes for the increase of lift, hence a net payload advantage.

    Slight Turbulences expected for the Airbus Helicopters H225M deal with Poland

    [The News Magazine] Wprost says that four months on from the selection of the H225M in April for the tri-service deal, the contract is no closer to being finalised – particularly around industrial offsets.

    With national elections due in the autumn, it suggests that officials from both the defence and economic affairs ministries are anxious to leave any decision to the next government.
    [...]
    lack of a folding tail boom, issues with the infrared target designator and the speed with which the cabin can be reconfigured.
    [...]
    Airbus Helicopters has promised to deliver the required specification – including items like the folding tail boom for the 14-15 examples destined for the Polish navy.
    [...]
    Previous reports suggested the acquisition was worth up to Zl13 billion ($3.5 billion), but Tomaszewski says the final figure will not be known until it concludes negotiations covering the provision of “a training package, simulator, and the construction of a logistics centre”.
