Designing the World's Tiniest Manned Suborbital Vehicle 153

Posted by Unknown Lamer from the more-fun-than-a-roller-coaster dept.
cylonlover writes, quoting Gizmag: "Generally speaking, companies developing suborbital manned vehicles brag about how much elbow room their spacecraft will provide passengers. They say there will be plenty of room to float around during the weightless portion of the flight, that there will be no fighting for windows, that passengers will comfortably endure the high-g portions of the flight ... and then there's Copenhagen Suborbitals' Tycho Brahe. CS's Tycho Brahe is a one-passenger capsule intended for a purely ballistic flight to a peak altitude approaching 100 miles. The passenger is just along for the ride, with no mechanism to steer or otherwise pilot the capsule."

    Looks so small you haven't even got room to put you hands up to cover your eyes, let alone wipe your breakfast off the glass.
    One can only hope the canopy is made of Peril Sensitive glass [hhgproject.org], and you get the option of editing any inflight videos so your friends don't get to see you screaming like a schoolgirl.
    I hope they subcontract with Depends, because you know someone's going to need them, especially since the parachute is at the bottom, and the final descent should be sufficiently terrifying that you wouldn't want anything else floating around your screaming mouth.

        But much poorer vertical acceleration. Possibly lower range per fuel tank too. Its an apples and oranges thing. "Better" also needs some clarification.

        Remember that aerospace works under the opposite optimization scheme from cars and consumer goods. Simplify and add lightness, that sort of thing. From a design standpoint they are not directly comparable.

      I have no worries about the weight limit though, as there is no way in hell that I would ride on this.

    • that's not how you determine if someone is overweight. this is: http://www.bmi-calculator.net/ [bmi-calculator.net]

      a lot of people weigh more than 154lbs and are perfectly healthy. you compare their weight against their height and adjust for gender. if you're a male 6 feet tall or more then you are underweight at 154lbs.

    From the web site, about an unmanned test flight last year:

    Due to trajectory anomaly the spacecraft was separated and the parachutes had to be deployed during great speed in order to save it. The parachutes were not able to deploy correctly due to the speed but even with a "knot" of parachutes we had a low enough impact on water to recover Tycho Brahe as one piece.

    I think I'll wait until a few more "successful" test flights have been performed.

        They aren't either -- offering, that is. Peter Madsen is the only one going; although perhaps eventually others in the core team may get to try too. If you get to go, it will be because you have been part of building it, and in that case you have an intimate insight into the risks involved.

Perhaps irrationally I don't get claustrophobic in sailplanes, which are hardly very big inside. This vehicle has achieved something I thought impossible: it travels through the air and it makes me feel claustrophobic just looking at the picture.

    • Go ahead and wait, while those who are more adventurous get to live on the edge and pursue their dreams. By the time the nice, safe, comfortable version of civilian space-flight gets rolled out by some mega-corporation, a good portion of the excitement and romance will be gone.

        Don't be too hard on Tycho Brahe. He was no more "wrong" than Ptolemy, and both of them made important contributions.

        Arguably, if your objective is to predict where the planets will be at a certain time, neither of their models is "wrong." It's just that the Copernican model is much simpler and more elegant, and therefore more persuasive in the sense of Occam's Razor.

        Tycho knew that his model was not popular, and pleaded with his colleague Johannes Kepler to give it some consideration. Like many great me

I am well aware that from a purely geometric point of view it makes no difference at all where in the Solar System you take as the reference point. However, there is the awkward matter of why the laws of motion apply. Once we add in the gravitational equation, it is obvious that the centre of the Solar System is a point around which the Sun itself wobbles as the planets move in their orbits.
