What are the limits to CCRP bomb release?

[T_A]

i`m trying to do a low (200ft) and fast (mach 1.2) CCRP bombing on a lased target with GBU-12

flying level to the target works fine , slight pitch up angle also work some times , but with higher angles it doesn't always work.

 

i`m trying to loft the bomb so i wont have to go above it, i AM getting the release cue and holding the trigger to release, but no bomb is released.

going around at more 'relaxed' condition and the bomb will pickle.

 

is there an AoA/G/Mach limit to releasing?

Very interesting question

[RAZBAM_ELMO]

Can you post a video.

Is the gbu selected on the pca with master arm on.

Is fuse type selected to tail or nose.

Are you in Cat1 or Cat3

Is TAS and radar altimeter selected.

Master arm on , like i said , if i go another pass straight or slight up angle it will release on target

fuse set for instant

Cat1 / Cat3 ? if you are referring to FBW limiter i`m in stores mode.

TAS and Rad Alt on.

 

video is a bit of a problem for me to post atm.

[RAZBAM_ELMO]

Track file maybe? Try lofting at different AOA and g loads. Maybe there is limits but RAZBAM has not released those.

I'm not fully aware of consequence in DCS World of supersonic bomb release, but bombs carriage and release is usually limited to M0.95.

We already had a discussion here about supersonic bombing, with video showing how bad it is to release stores at supersonic speed form this kind of aircraft (in flight collision).

 

There is a special attack mode to toss bomb from low level to get some stand off range.

You need:

- to choose a waypoint that will be your Initial Point, and select it as "DEST"

- enter target coordinates as "offset" to this waypoint.

- when in attack mode, select "PI" option (Point Initial) on PCA (only available if the offset waypoint exist)

- designate the PI with diamond

- then steer to target

- pull up when you get release cue and hold trigger for auto release.

 

All that below M0.95

 

But this mode is under work by Zeus and hasn't been reported as "ready" yet.

is there an AoA/G/Mach limit to releasing?

Yes there are, but I don't think we can have them (not public data), apart from the "subsonic" limit posted by jojo juste above.

 

Let's assume perhaps?

 

AoA:

Max AoA in CHARGES mode is ~20° IIRC. So of course this is our absolute max. I suggest adding a safety margin of 2-3° minimum so max AoA around 17-18°?

Min AoA: dunno if it's useful? See Load factor below...

 

Load factor:

Min: It's probably safe to say that you cannot have negative Gs, at least for non-rail-launched weapons. With a safety margin, I would say that G should be above 0.5 when releasing.

Max: About the upper limit, I guess it depends on the weapon. For all air-to-ground weapons, the aircraft itself is limited to 5.5G, and we know that CCRP principle is to "toss bomb" somehow, so G>1; without more data, I guess we can keep 5.5 as the max.

 

Speed:

Min I guess somewhere around 300kt? Delta winged aircraft love speed, let's give them some.

Max M0.95

[tombeckett2285]

For information only, the Buccaneer (in long toss mode) had a minimum ground speed during attacks of 510 knots (preferably 560kts), and pulled up at 7 degrees per second which was approximately 4G.

Bomb release limitations (for both CCRP/CCIP):

 

- Cannot be released when there is not enough air flow on the wings. (i.e.: too slow and high AOA).

- Cannot be released when g forces are equal or less than 0.4g

- Cannot be released with landing gear down.

- Shouldn't be released when flying over 0.9M but system will not prevent release.

[ZHeN]

0.4g

or 4G ?

[TomCatMucDe]

or 4G ?

 

 

 

Equal or less than 4G wouldnt make sense obviously

[Zeus67]

0.4G. That way the release bomb(s) won't float up into the wing/airframe.

[TomCatMucDe]

Is there a max G limit?

[Britchot]

I'm only guessing but I would think the max release would be more than the CHARGES FBW mode allows, therefore you're safe while in the correct configuration and > 0.4g.
