    Thanks Nauga, I was just curious from what my jet engine mechanic friend said about a straight pin eating the engine.

    The T-38 engines aren't going to ingest ice off the wing. It could form ice on the engine inlet, though. I worked T-38's too. Engine 8th stage bleed air is used for cabin pressurization/air conditioning, canopy defog, canopy seal inflation, G- suit, hydraulic reservoir pressurization and engine anti-ice.

    Is it fact what my neighbor told me the jet Glenn? I know some engines can "eat" more than others. He worked on 38 engines at Columbus so unless he was messing with me I believed him.

    My understanding is the inlet guide vanes and nose dome "bullet" are anti-iced, but that doesn't provide any protection from ice ingestion that may form on the engine inlet or fuselage forward of the inlet. There are no jet engines that like chunks of ice that have liberated from the airframe. Some fair better than others, like centrifugal compressors, they are much more robust than axial flow.

    They can fly C-130s into hurricanes but not tactical jets? Is there ice in them?

    Most tactical jets don't have all the ice protection that transport aircraft have, like wing and stabilizer anti ice. They are considered "all weather" aircraft because they can quickly get out of, or through, bad weather if they enter it.

    I doubt it would take much metal to FOD a J85 but I wouldn't think a single straight pin would do much. I'm not aware of any standout FOD issues on anything with J85's or CJ610s (T-2C, Lear 24, etc...) so I kind of doubt it. I *have* seen a T-38 swallow enough rain that I thought the fire was gonna go out; with no harm done, but the rain/wx issues IME were more due to the airframe, not the engines.

    Nauga,
    fortunate

    One of the amazing things about axial flow, there's still a centrifugal effect, and, the fire is contained in the burner, somewhat protected.

    Anyone else think that landing gear looks REALLY tipsy in a crosswind?

    Like an exaggerated version of the F-16's LG.

    Funny thing about the gear is that it's "crosswind" gear, IOW you touch down in a crab and let the gear absorb the side loads.

    Nauga,

    A straight pin will probably cause damage that a crack could initiate from and when that portion of the damaged blade(s) liberates it could cause much more damage.
