[CORRECT AS IS] Fuzes Wrong?

[hein22]

I noticed that the general purpose bombs do not follow Wags video or manual, they will explode as long as one of the fuzes is set, instead of needing both mech and electr fuzes set to nose and inst respectively. Track attached.

This is correct in sim. Only one fuze is needed, they’re independent. Two for redundancy.

 

I think incorrect is MFuze for LGB. In RL MFuze should need to be on, since it pulls the start wire on the guidance unit battery. Without it, it goes dumb. Would be nice to see this changed. Edit: Although I'm assuming here that Hornet logic is Mech Fuze is always Nose Fuse and Elec Fuse is always Tail.

Thanks Avro. I didn't quite understand the LGB thing. Do we or do we not have a bug in LGBs fuzes?

I’m not 100% certain for LGBs. I know the nose arming wire pulls the battery start, and obviously the tail wire pulls the fuse in the tail (ELEC).

 

Most aircraft have options to set NOSE or TAIL or both. Hornet has MECH or ELEC. Does the Hornet know to pull the nose wire when LGB is used, even with the MECH (nose) selected OFF? Might be a bug if my logic is correct.

Mmm, the hornet has the option for N/T in the Mfuze subpage. I see a possible mistake in your logic, maybe you can tell me if I'm correct: You said that the instructions made by wags and EA manual refer to a redundancy (which is totally fine and common practice) and that only one of the fuzes is needed. So the same should be true for the LGB? On the other hand setting any mech fuze for an LGB in dcs makes the bomb dud and can't drop it of course.

You can't turn on something that is unavailable. The CCG precludes the usage of the nose fuze.

Care to expand?

The device mounted on the nose of the bomb to help it track the laser (called CCG), restricts the usage of the nose fuze. I don't think it even exists on laser-guided bombs (I have charts showing the assembly and no mfuze is shown). They all have electronic fuzes placed near the tail of the bomb.

 

So in our hornet, if you set Mfuze to anything other than off, you are asking the system to do something it can not.

No one’s claiming that the LGB nose fuse is an actual fuse....but there’s a wire connection to the nose fusing mechanism in the pylon. When that NOSE wire is pulled upon weapons release it starts the battery that powers the guidance unit. The nose fuse option needs to be selected in cockpit in order for this to happen.

Roger, thank you Bar. How does the electronic fuze activates in an LGB when it impacts? Does it have some sort of accelerometer?

Ah, now I understand what you are saying... I'm sure ED will consider changing this if it's accurate and if sufficient documentation is provided.

Laser guided bomb - Nose solenoid is used for the guidance and control to activate the thermal battery in the G&C unit. There is no actual fuze but Mechanical Fuze settings should or when the solenoid is energized, pull the wire for the G&C thermal battery on store release, or it won't guide or track target laser illumination. I don't recall any positive arming configurations for the G&C thermal battery.

So should it or should it not have an mfuze nose setting in cockpit?

You can read up on how GBU-10/-12/-16 and -24 LGBs are armed in A1-F18AE-LWS-000, which describes no use of a mechanical fuze, only an electric fuze, along with arming safety switches and safety pins, as AvroLanc mentioned.
