    Who would've thought that having armed men would deter attack:

    Mateen went to Pulse only after having scouted other venues that night that were wholly unrelated to the LGBT community, only to find that they were too defended by armed guards and police, and ultimately chose Pulse only after a generic Google search for

     

  2. Thanks to EE for the translation:



    Technical documentation for the UTD-30 diesel was complete by the end of 1958. A prototype was finished in June of 1959. Compared to V-2 engines, it had better mass and size. The height was lowered by changing the cylinder angle. The piston travel distance was reduced from 180 to 150 mm, the RPM was increased from 1800-1900 to 2600. The fuel efficiency was comparable to the 5TD.

     

    The overall heat transfer to water and oil was less than for the V-55 engine which had the same power. The UTD-30 was only inferior in heat transfer to the 5TD (200 kcal/h vs 150 kcal/h). The average piston speed of the UTD-30 was 13.5 m/s, which is higher than all production and experimental engines. The high power density of 435 kW/m3 was achieved by reaching higher cycle temperatures. Without applying pressure boost and by turbocharging the engine by adjusting the excess air coefficient, the developers simplified its design, but created difficulty with allowing components of the piston group to function due to higher temperatures. The temperature of discarded gases was 700 degrees and higher.

     

    The pressure-boost-less variant of the UTD-30 had nearly no turbocharging reserve left. The engine needed more air, which could only be achieved by boost.

     

  3. Probably just what they have. The engine design bureau at Kharkov decamped for Chelyabinsk in 1941 and never returned. Most of the brain power behind engines was at either Leningrad or Chelyabinsk. Omsk and Stalin/Volgograd also had good teams for light tank engines. I think it is highly telling Kharkov didn't have an attached engine bureaus like the other factories did and did every thing in house. 

     

    Also Uralmash did some cool stuff like the 16 cylinder engine in the Object 279. 

     

    Edit: According to DAV Kharkov only did two noteworthy engine designs in the 45-65 period: 5TD and the 5TDF.

  4. 5TDF, the engine in the T-64:

    An engine that was notorious for only being capable being built at Kharkov, which was not surprising since it couldn't even be produced at Kharkov for a few years. Meanwhile in Buzuluk, where they know what they are doing, we got the UTD-30, a short stroke design that was meant to be 15/15, a engine with 150mm stroke and 150 cylinder. But because of an arbitrary height requirement set by Morozov it was canned.

    If that looks small its because it's 1350mm long 940mm wide 775 tall

     

     

    ChKZ decided it was a cool idea to transversely mount a 1000hp engine so made the DTN-10. 10 clyinder engine and in a Soviet first ChKZ used exhaust gas in the supercharger:

    The backup engine was even smaller. It's the super charged variant of the UTD-30.

    The previously mentioned MAGA hat instagram account is probably a different Nicolas Cruz. Florida Voting Records for an individual who identifies at Nicolas De Jesus Cruz(use the CTRL + F function) of 19 years age is a registered Democrat before and after the Trump election

     

    Two mass shooters in three years; the Florida Democratic Party needs to get it's shit together.
