    What if the Me 262 had 20mm cannons?

    The specification I have read but cannot source says the MG213 had a muzzle velocity of 3,440 ft/s Compared with the .50cal air version it was 2,900 ft/sec. I would expect a 20mm ball to be heavier than a 0.5" ball and thus carry further. Do you happen to know if the .5 call round design was...

    What if the Me 262 had 20mm cannons?

    so you are saying that the triple chamber rotating MG213 gun gave a pilot the advantage over alternately equipped aircraft of shell weight, velocity and rate of fire. Thus qualifying MG213, in case we didn't get you the first time, was the the revolutionary gun requested by taly01. Is that...

    Feminine Iceburgs???

    If you mean does he believe that a certain sort of vibrations and audible sounds plus flashes of light from pressurised deep ice fractures presage a slippage catastrophe then i suspect he is looking into that - conventionally skeptically, along with a number of other ideas. If you mean does he...

    Feminine Iceburgs???

    I suspect I am about to be very boring. All publisher, editor, writer, reader relationships are built on trust. The reader trusts the publisher to publish truth. Sometimes the reader will make a mistake, trust a source that has no good editor review process. That is the serious claim behind...

    Feminine Iceburgs???

    Here's link to the brief Economist article which seems to bypass the pay-wall because it is in a foreign language but certainly on my machine auto translates. 'Nuff said? https://www.tianfateng.cn/19236.html

    Feminine Iceburgs???

    Well. I don't want a row or anything but the previous "hoax" papers were pretty well covered at the time. Faux scholarly article sets off criticism of gender studies and open-access publishing So I'm inclined towards skepticism.

    here's the man himself. To me he seems on the level and a smart guy. Q&A: Author of 'feminist glaciology' study reflects on sudden appearance in culture wars

    Feminine Iceburgs???

    For funny. Well OK. Laugh for sure. But like someone already said there is sense to what the guy says. There is or was a macho bias in glaciology and a tendency to overlook the understanding that the indigenous people have of Glaciers. They would hear and feel the vibrations that lab...

    Could proximity fuses have halted the bomber offensive against Germany in 1944?

    A "new" original source, for comments. I rate this highly as it is from government authority, near contemporaneous and gives a clear account of the function of the circuit which is precious as no one nowadays can really confidently say they know enough about Vacuum Tube design to be able ton...

    Proximity fuzes on fighter aircraft cannons?

    yes and yes and yes. The thing to appreciate about Butement design is that the electronics is scanning the space in front of the shell and around it every 100 microseconds or so, or every 33cm of advance down range. If the threshold is not reached in one sweep because the target is 34cm...

    Proximity fuzes on fighter aircraft cannons?

    Hi, I think what you read was this. How a Radio Proximity Fuze Operates Among various possible types of radio proximity fuzes, an active-type fuzed operating on the doppler effect was selected as being the most promising method. In a doppler-type fuze, the actuating signal is produced by the...

    Proximity fuzes on fighter aircraft cannons?

    The guns may date form 1951 or so but the proximity fused ammo for them was a much later development. Looking through online sources briefly it seems the history is this: The 40mm Bofors was de-emphasised in US procurement at 1945 because the 3" installation using VT ammunition better fit the...
