  1. The international air corridor over the Ukraine is still open. All international airlines used it up today for their routes from Europe to South East Asia.

    And it was believed to be safe, because the pro russian rebels had no weapons to harm a plane in 10.000 meters. They have Strelas and Iglas which can reach 2 or 3 km maximum and which are used to down some ukrainian planes.

    News tell us, that the plan was shot down by a BuK SAM system. Its the question who fired the missile on the Malaysian flight.

    The ukrainian president says it were not the ukrainian armed forces. The russians say, they have no BUK in this area.

    Whom you can believe? I dont know. I only can remember that some years ago a training shot of S-200 Vega accidently downed a airliner over the Black Sea. Perhaps something like these could happen again.

    The separatists claimed to have captured a BUK system a few weeks back.

  2. That is odd, it works over here. The pylons them selves are fixed, the adapter however is not, it is called for in the inner weaponstations:

     

     

    [LeftInnerWingStation]

    SystemType=WEAPON_STATION

    StationID=3

    StationGroupID=4

    StationType=EXTERNAL

    AttachmentPosition=-2.05,2.74,-1.28

    AttachmentAngles=0.0,-1.0,0.0

    LoadLimit=1400

    AllowedWeaponClass=BOMB,CGR,TER,RP

    AttachmentType=NATO,USN

    ModelNodeName=adapter_inner_L

    PylonMass=10.89

    PylondragArea=0.00

    LaunchRailNodeName=

    MinExtentPosition=

    MaxExtentPosition=

     

    that is why I added two new weaponstations, specifically for the sparrows, with no ModelNodeName so the adapters don't show up:

     

     

    [sparrowWingStationLeft]

    SystemType=WEAPON_STATION

    StationID=17

    StationGroupID=2

    GroupLimit=4

    StationType=EXTERNAL

    AttachmentPosition=-2.05,2.74,-1.22

    AttachmentAngles=0.0,-1.0,0.0

    LoadLimit=1400

    AllowedWeaponClass=SAHM

    AttachmentType=NATO,USN

    ModelNodeName=

    PylonMass=10.89

    PylondragArea=0.00

    LaunchRailNodeName=

    MinExtentPosition=

    MaxExtentPosition=

  3. Okee-dokee, given that math is not my strong suit, I had skipped working out the formula given in the first post and went straight for the tool; however I just tried the formula and it doesn't seem correct even for the example given. The formula is: Delta V=10xSpecific Impulsex(initial weight/final weight)in M/S. So plugging in the author's numbers we get: Delta V=10x245x(335/(335-132))in M/S. Or 10x245x(335/203)in M/S. Or, 10x245x1.65=4042.5 M/S, not 1227 as the author states. Am I screwing this up somehow, (wouldn't be the first time)? Any guidance would be appreciated. Thanks in advance.

     

    you forgot to take the logarithm of the weight ratio, ln(1.65)=0.5

     

    The equation is the first post is known as the Tsiolkovsky rocket equation, see http://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation
