Hyperloop One's Full-Scale Pod Reaches 192 MPH In New Nevada Track Test (techcrunch.com)

Posted by BeauHD on from the record-breaking dept.

On July 29, 2017, Hyperloop One competed a test at its full-scale Nevada test track that travelled a high speed, running nearly the entirety of the 500 meter (1640 foot) test route. "XP-1, the company's first Hyperloop pod, reached speeds of up to 192 mph during the test, which is getting closer to the planned functional speeds of future Hyperloop installations planned for Dubai elsewhere," reports TechCrunch. From the report: The new test breaks the recorded speed record for any Hyperloop tests ever conducted, including those done by research organizations participating in SpaceX's pod design competition. It was conducted on July 29, 2017, and included a 300 meter acceleration phase, with gradual breaking to come to a stop after that point. Hyperloop One depressurized the tube for the test track down to conditions similar to those at 200,000 feet above sea level, which is part of the Earth's atmosphere where there is very little friction and resistance to the rarified air. The company says that all aspects of the system, from motors, to electronics, to the vacuum pump and magnetic levitation mechanism worked well during the test.

      Come on now - what I wrote doesn't even rise to the level of a Poe. Its pretty obvious that the US was a world leader at one time in installing ad using train transportation. The idea that we need to catch up with the rest of the world because we don't have any experience in train transportation is silly.

      The reason that the US is behind the curve with high speed trains is because we have lost the will to do such things, and are well along the way to ceding technological superiority to the rest of the world.

    v1^2 - v0^2 = 2ad
    a = (v1^2 - v0^2) / 2d

    v0 = 0
    v1 = 192 MPH
    d = 300 meters

    a = (192 MPH)^2 / (2 * 300 meters) = 12.28 m/s^2
    = 1.25 g
    arctan (1.25 g / 1 g) = 51.3 degrees

    That's gonna be trippy riding inside. Since there are no windows, you only have the apparent direction of gravity (acceleration) to determine "up". It's going to feel like you're in a plane climbing up at a 51 degree angle. That is, anyone trying to stand while this is going on is going to be leaned forward at 51 degrees relative to vertical at rest. (I'll add that the earlier test to 69 MPH in 30 meters is 1.68g, giving an apparent inclination of 58 degrees.)
