Tracker Posted November 18, 2011 Share Posted November 18, 2011 The most powerful (and ridiculous) engine RI has come up with yet. Yes, I did put Cirevam next to that giant and yes, it does have a fission reactor. Two actually. Anyways, here are some specifications: Power output: 17 MW at shaft Weight: Likely in the area of 80000-140000 pounds from all of the shielding. Size: approx. (in feet) 36x16x8 Notes: Turbine does not need to be running for it to power a small house. Secondary water cooling (not yet mounted) alone is enough to do that. .......... It has two nuclear turbojet cores. .......... Could be useful for a small generation station, a destroyer of the floating variety, or mounted an a heavy transport vehicle as a mobile source of mechanical energy. .......... I did not mistype the number 10 in the title. Taken during construction (hence the mess): The power turbine. The two engine cores. The Startup is a bit long, but not complicated. First, the smallest turbopump is spooled with a small motor, powered either by thermocouples heated by decay heat from the reactors, or a small battery. That gets water moving through the reactors. If neither unit is hot enough at this point to get water boiling, one is restarted at a very low power just long enough to reach a temperature of about 473 kelvin. The next stage happens on its own: The steam spools the main turbopumps, allowing the reactors to be restarted to raise their temperature to around 850 kelvin (if they are not already there) to get the auxiliary generator (driven by a steam turbine) going before being shut down to avoid overheating. The power from the auxiliary generator is used to drive the "starter" motors for the main engine rotors to near operating speed. The output can also be turned to speed this process up a little. The final step is to restart (proper) the reactors with a pair of neutron guns. The guns were also used for the partial restarts to get the rotors and pumps going, but only if there was enough power to drive them. If there was not enough power available and no external source, a spontaneous fission restart would be needed. Spontaneous fission restarts tend to be very unpredictable, so this obviously best avoided. Like Dark Pluto and Pathfinder II, it uses "hypergrade" plutonium, containing less than 1% Pu240. 20 kilograms of fuel are in each unit with very thick neutron reflectors to reduce the amount of neutron radiation. 6.2 kilograms is enough for a good sized weapon, and while they can not go boom due to the general shape of the cores, they can get extremely hot if not designed correctly. To add to the problem, they will be in the hands of people who will only have a faint clue on how to operate them. People like Sparks and DUMMY are a little less competent than most, so these engines are a little more idiot proof than those in Pathfinder and DP. I stuck it on a trailer: There are four pivot points on that trailer. Two for mounting the load, two for the tie bar. Link to comment Share on other sites More sharing options...

Tracker Posted November 19, 2011 Author Share Posted November 19, 2011 Yes. Yes it is. And I did carry over the capitalization. The problem is copyright related, I presume. Link to comment Share on other sites More sharing options...
Cirevam Posted November 19, 2011 Share Posted November 19, 2011 There's no problem, I just thought you made a reference. If I cared about copyright stuff then I would have complained about my likeness in many of your works long ago. Link to comment Share on other sites More sharing options...
