Support of more fuel and nuclear thermal jet (PLS REPLY!) #25

Open Kerbinator-Fras opened 5 years ago

I need support for: 1.The fuel variety and combustion energy and ignition temperature veriable as parameters in config files,so we can support more types of fuel(other than LH2,LMe,Kerosene). 2.Nuclear thermal jets(turbojets/ramjets).They are thermal engines not propellers which has aerodynamic output based on RPM,however it does not consume any fuel and thermal system is independent from air since no combustion is needed which differs feom jet engines. You need to write a source code of this using a seperate .cs file. (I think I could have reverted to stock jets but I think AJE is orders of magnitude more realistic and I don't want to give up this awesome work.)

The therodynamic model currently used in AJE is very simplistic and is really only valid for mixtures of earth air and jet fuel. I've meant to replace it with something better and more general for a while but haven't gotten around to it, it would also be a fair bit of work to do.

Sorry I didn't check my mail.Thanks for your reply. Well I think that you can do nuclear jet first.This moder is even simpler than fueled oxygen-breathing jets,And this is historical since project Pluto SLAM used that (Tory-IIC).And this can greatly improve the performance of Earth SSTOs since it haas a high Isp in closed cycle,and it can gain the first 2+ km/s for free.So write scramjet(rated for M10) and turbojet(rated for mach 1) and turbo-ramjet(rated for mach 1 & 3) But the hydrogen-breathing jets may be quite hard due to unknown performance.

Oh, also AJE doesn't currently have a thermodynamic model of a scramjet ... the physics involved is very different than jets that do subsonic combustion. I saw one paper that might give a useful model, haven't gone through it though.

Yeah this is a real problem. However nuclear ramjet may be better theoratically since it is theoratically easier. able to give it a resonable thrust based on CALCULATION(not sample curve).(You can ignore consumption rate of Uranium such as fixing it to 1E-12) So do first thanks (better if compatitable with other planet atmosphere)
