[Research] Detailed Heat Mechanics

Krait Mk2

6E Power Plant (Stock) - Heat Efficiency 1.0
5C Thrusters (Stock) - Power Draw: 5.1MW

StartEndDuration
20:30:3020:31:411m11s
20:36:3020:37:411m11s
20:39:3520:40:461m11s

71 * 1 * 5.1 = 362.1 BTU

Considering this is meant to be the Alliance's Smuggling ship for the naughty commanders accourding to Frontier; it's kind of terrible. +450 IMO for smuggling.

engineer it. mine idles at 19% with 6c bi weaves active and 14% with them off
7a efficient power plant, 6a clean drives both with thermal load reduction

she's a quiet ship

Thanks for the info. Updating the OP.

It has literally the exact same core modules as the python, but a lower heat capacity. Regardless of how quiet it is, it is objectively (significantly) inferior to the python from a heat management standpoint. Kind of strange, since the Krait was billed as a more smuggler-friendly option to the python.

I have better stats on an Asp Scout (just pointing out due to the 'smuggler' role).
 
Concerning the Krait, my bet is that what Frontier's livestream remarks meant is that they've given it a really low sig.

Remember that heat signature (which affects sensor resolution, gimbal weapon tracking and availability of seeker missile lock) is a product of

- Temperature
- Range
- Hidden Sig Value: Dev specified but not stated

... with emissive and SR providing their own overlays.

If I am correct, then in precisely the same way that an Anaconda (high sig) will resolve and become targetable by missiles at a much longer range than a Viper III (low sig) running at the same temperature %, a Python at a given temperature % will resolve and become targetable by missiles at a much longer range than a Krait.

Which presumably has the same effect on NPC cop scans.

I seem to have drawn a different set of data, using the Krait's default modules:

7E Power Plant (Stock) - Heat efficiency 1.0
6E Thrusters (Stock) - Power Draw: 5.04MW

Durations:
88.35s
88.40s
88.37s

88.37s * 1 * 5.04 = 445.38 BTU

This seems to make considerably more sense, as it puts it roughly on par with the Python's BTU of 450. At 362, it has considerably lower BTU than its Medium class should provide it (right next to the Vulture).

Could be. That could actually be useful, if it's the case. I'll have to test for this next time I find the motivation to play the game.

...Might be a while, so someone else testing this might be the better option.

Added to the OP. Until one or the other is verified by a third party, I'll just show both numbers.
 
Just did a couple tests for the Krait and the Challenger

Krait:
7A Power Plant - Heat efficiency .4
6A Thrusters - Power Draw: 7.56MW

Durations:
149.39s
149.31s

149.39 * .4 * 7.56 = 451.76


Challenger:
6A Power Plant - Heat efficiency .4
6A Thrusters - Power Draw: 7.56MW

Duration:
156.9


156.9 * .4 * 7.56 = 474.5
 
Will heat efficiency significantly affect heat rise when charging a FSD close to a star?
To some degree, yes. The higher (worse) your thermal efficiency is, the more heat your power plant will generate powering your modules. The higher this idle heat is, the more of your ship's natural cooling capacity is "used up", and thus not being used to deal with FSD charging heat and heat from the star.
 
Just tested my Krait thermal capacity:

5D Thrusters: 5.14MW
4D Life support: 0.56MW
0I Heat sink launcher: 0.20MW
Total power used during silent running: 5.9MW

5A PP (G5 low emissions -65% heat): 0.4*0.35 = 0.14

Silent running time: 9:02 (542 seconds)

542 * 5.9 * 0.14 = 448 BTU

I found it's temperature was lower than the Python when it hit supercruise glide during my Skardee I test, so it seemed strange to me that it would have poorer thermal capacity.

I'll put it down to the fact that I piloted it better this time, and that the Python has the same thermal capacity (unless ships have some sort of thermal reflection/absorbtion property aside from the internal heat capacity...).
 
I have better stats on an Asp Scout (just pointing out due to the 'smuggler' role).

my main goal was to stack as much while keeping under 20% heat. the build is also vital in keeping the engines and frame shift drive operating under 40% power. perfect for smuggling and long stretches of silent running as needed without making other sacrifices while ensuring proper fail safes during extreme scenarios.

excuse me if it seemed as i was bragging about having the best. i was not. simply providing an example of what was possible.

What I'm doing wrong?

Thanks for the testing,
i had the feeling the challenger runs super smooth in SR.
