razo+r Posted December 4, 2016 Posted December 4, 2016 I don't know if this affects also other bombs, but when i set my fuze to retarde and release the bomb, it will go off instantly and without delay...
Azrayen Posted December 4, 2016 Posted December 4, 2016 Do Snakeeyes have delay (rear) fuze? (real question, don't know, wanted to be sure it's checked be4)
razo+r Posted December 5, 2016 Author Posted December 5, 2016 I don't know, that's why i'm asking which other bombs of the mirage would support delayed fuze then?
Robin_Hood Posted December 5, 2016 Posted December 5, 2016 (edited) GBU-12s do not work in delayed fuzing either. However, contrary to the Snakeyes that explode immediately, the GBUs don't explode at all. The manual currently states that "RET and INST values are only valid for Mk-82, Mk-82S and GBU bombs". Also, it was my understanding that a tail fuze will delay the explosion by less than a second, while currently the delay is about 4 full seconds - which makes it pretty easy to check if the delay is working, at least.

No problems whatsoever :thumbup: From an hour ago: Edited December 6, 2016 by CrashO
Robin_Hood Posted December 6, 2016 Posted December 6, 2016 Odd, I just made a test and it seems to work now (GBU-12). Maybe it was corrected recently? However, they seem to impact instantly, so I'm not sure the delay is taken into account (compared to the Mk-82). 2nd French Fighter Squadron
jojo Posted December 7, 2016 Posted December 7, 2016 (edited) IRL the delay is about some "ms" not 4s. Just the time for the bomb to go through the walls and detonate inside a building (it's the general idea). So you wouldn't "see" it. This kind of setting is part of a "science" called "weaponring" = choosing the right weapon, the right setting and the right delivery profile to achieve the desired effect on target within the constrain of it's environment. Then it's about DCS World... Edited December 7, 2016 by jojo Mirage fanatic ! I7-7700K/ MSI RTX3080/ RAM 64 Go/ SSD / TM Hornet stick-Virpil WarBRD + Virpil CM3 Throttle + MFG Crosswind + Reverb G2.

Frederf Posted December 7, 2016 Posted December 7, 2016 Is French Air Force using US-model fuzes like M904, M905, FMU-139, etc. or not? Is arming by lanyard pulling or electrical?
jojo Posted December 8, 2016 Posted December 8, 2016 AFAIK it's lanyard pulling (I talked with a M-2000 weapon crew once during airshow). I can't be very specific about fuzes, but it's likely that US models made their way to FAF along with US bombs. Mirage fanatic !

Eddie Posted December 8, 2016 Posted December 8, 2016 Do Snakeeyes have delay (rear) fuze? (real question, don't know, wanted to be sure it's checked be4) They can have. Just like any weapon the fusing selection is up to the operator, there is no standard configuration in reality. If you do wish you can read about some of the fusing options in this doc: http://www.globalsecurity.org/military/library/policy/navy/nrtc/14313_ch1.pdf 2
mvsgas Posted December 8, 2016 Posted December 8, 2016 If you look at page 4-16 you can see the are a lot of options for the Mk-82 type bomb https://docs.google.com/viewer?url=http%3A%2F%2Fcsef.ru%2Fmedia%2Farticles%2F4361%2F4361.pdf To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true..
Robin_Hood Posted December 9, 2016 Posted December 9, 2016 (edited) The thing, is, we shouldn't see a difference visually (I have seen 25 ms delay for Mk-82), but there should be a difference in terms of effect. At the moment, I think it is the reverse, right (Mk-82 have way too long a delay but fuzing doesn't change the effects AFAIK because it is not yet modelled in DCS ?)

Frederf Posted December 10, 2016 Posted December 10, 2016 Is the inert-instant-delay switch always pulling the same combination of lanyards for each position/ (e.g. inert-none, instant-both, delay-forward)? Presumably a low-drag bomb with pilot-selectable fuze action would pull a delay-action fuze for delay action detonation, probably a FMU-139. When instant is selected the system would also pull the lanyard for an instant fuze (M904 potentially). There is no fuze that takes more than one lanyard input. The FMU-139 has two setting selections which are chosen based on experienced deceleration on launch. A high-drag bomb I suspect would be configured to always drop high drag if armed at all. There's no point in an armed low-drag drop if the airplane can't select between low and high drag solutions at will (manual backup bombing being a possible exception). There are so many possibilities and potential restrictions that DCS isn't equipped to simulate. A simple and consistent modeling would be for all instant fuzes regardless of drag device to correspond to the instant position of the switch and a delay action on the retarde position. The delayed action should be a realistic 250ms or less and hopefully the damage/radius values altered for two nearly-indistinguishable bomb objects to be spawned based on that identity. Low drag should always be spawned from low-drag bomb carried stores and high drag unopened from inert and high drag opened from any armed state.
