Laser guided rockets

[GIGA_HORSE]

When JF17 was release I remember we were told that laser-guided rockets are temporarily made into beam riding while IRL they are not. When is that planned to be changed?

[foxwxl]

Currently, BRM still use the beam riding scheme. If new suitable scheme is availiable, it will change.

It's probably an ED problem. Unless Deka figure out how to use laser maverick code instead.

[GIGA_HORSE]

Well, I watched a couple of demonstration videos about new Kiowa by Polychop and they have laser guided rockets similar to JF17 and they are not beam riding, so either Polychop figured out how to do it or they use different mechanic.

[shaHeen-1]

Any chance you could post a clip here for reference?

There are laser rockets already in-game in the su25

If you mean the A, those are SALH rockets do not spin using one axis of control

[amalahama]

But do BDRM rockets spin? I can understand they rotate to stabilize the flight path, that's common among airborne rocket launchers, but the very unique vikhr's corkscrew flight path is due to the beam riding sensor mechanism

The whirld (Vikhr) flight is because two rocket boosters at the sides, and then the two half-circle shaped control wings at rear. The Vikhr missile is made purposely to rotate as it made its control design easier as you can just steer missile with two control surfaces instead four.

 

Nothing about beam riding guidance but just the design make Vikhr simpler, cheaper and more accurate.

The beam riding and single axis control of a rolling airframe are not intertwined, look st the Naval rolling airframe missile, it is infrared homing.

 

The BRM-1 90 is a rolling airframe with one axis of control, but SALH, which is not a scheme currently coded in DCS

Of course, completely forgot about Su25 laser guided rockets, other that vikhrs.

 

I think BRMs spin, but even if they don't. It doesn't matter, they are but beam riding IRL. In game, because they are not beam riding, their accuracy is poor when angle between you and target is high, they tend to overshoot.

Since the last patch BRMs are virutally unusable, unless you fly straight and slow with flaps @ 200-250 knots till the missile hits to provide clearance from the anti-air engagement range of at least 3-4NM. Higher speed will make you enter AA range before missile hits. And any manuevers at high speed or at high aspect towards the riding beam after shooting will cause a miss. That was not the case before.

Give BRM loft!!! I want to hit things from 10nm XD

Yup, it was really a bad idea to make a changed without being tested throughly. It ruined players gameplay.

[Babok]

I see i understand why laser rocket are so inacurate right now.

[Tiger-II]

I had better luck coming in at a steep angle.

 

The missiles seem not to be flying fast enough, which is why they seem to be struggling.

 

Anyone checked the speed in F6?

[Oceandar]

Just tried it again after newest patch and it seem the rocket still having hard time chasing the laser spot, not as bad as before but still it missed alot. I really missed the old rockets FM. Quite dissapointed tbh.

 

Is this BRM-1 90 flight model still WIP or regarded as finished?

 

Thanks

[AeriaGloria]

It needs API changed to allow rotating body and SALH

[foxwxl]

It's still using beam riding scheme at the moment, and if you treat it like the beam riding, the BRM should work fine within 4.8NM

[Floydii]

It is curious that they prioritised spin stabilisation over the correct laser guidance method.

 

Beam riding vs SALH has a significant impact on the usability of the weapon (specifically being less able to break away from the target without affecting missile range). Whereas the spin stabilisation is not something you really observe unless in F6 view.

 

I'm sure there are some aerodynamic concerns towards the edge of the BRMs envelope as it slows it's speed and hence spin, but we are talking about an Air to ground munition (not the sacred cows of Air to Air), so some abstraction to give it a realistic max range in order to give it a more realistic guidance behaviour would be preferable.

This may sound sarcastic but it’s not I’m actually curious as to what you mean by treat it like beam riding?

[AeriaGloria]

Becuase it’s beam riding right now, like a Vikhr

But do you keep flying straight or something cause it’s beam riding?

[AeriaGloria]

Flying straight makes it fly better. For me I have gotten away with gentle maneuvers when the rocket has enough energy, but I haven’t tried it in a few patches I know things changed

Think of this:

1. Beam riding weapon have to keep inside the guidance beam or it will miss.

If the beam moved, the weapon have to follow to maintain inside the beam.

 

2.Any hard deviation on original launch path will move the guidance beam away(the LOS from TGP to target), the BRM have to use energy to follow up, to try keep inside the beam.

 

3.If BRM use too much energy to follow the beam, it will have less energy for terminal flight and corrections.

 

Then, MISS.
