Is drag from stores currently modelled?

[Kula66]

In the current FM (given that this is the one going to be used by most people, even in 1.1), is the drag of external stores modelled for all weapons? I was thinking primarily of all those big AAMs that the SU27/33 carry ... external tanks on the 15 certainly seem to make it slugglish, but this could be just their weight. Are conformally mounted stores (AMRAAMs) modelled differently?

 

Thanks, James

yes, in 1.02 (since 1.0 AFAIK) external stores affecting air-drag very much. try to reach max speed with AA rockets and without - you'll notice the difference.

Even with your full missile complement on F-15 you'll never reach the speeds that youwill while flying clean.

[Dmut]

yes, that's what I meant. drag from external stores affect both maximum speed and speeding dynamics.

But are different size stores modelled differently? Or is there just some generic drag modelled? I know the AFM will supposedly show drag from differential weapon loads ... so I guess this ISN'T currently factored in ...

Each payload in 1.0/1.02 has its own drag and mass but only total drag and mass of the plane depend on it. In 1.1 for Su-25/25T AFM the mass and the drag of the payload is connected to the certain point of airframe causing unsymmetric drag and roll after one-side weapon release or drop.

Thanks Yo-yo ... so I can rest assured that all those big AAMs on a Su-33 are causing more problems than the neat semi-recessed AMRAAMs on my killing machine :)

I have seen in some F 18 video that when the pilot drops a load...it seems that his plane kinda goes up since the weight has fallen, i.e., in a fixed perspective..from another plane flying at same speed beside it....kinda like a balloon when a single sand bag is dropped.

So, if I take an Su25 with 2x25MP and 2x29L, approach target and shoot one MP on the only active radar detected, then shoot the 29L on one of the main targets, since the first of each type is on the same side, I'll be just in somethin'deep!?!? :lol:

Far more noticable than drag, is the offset of weight upon releasing a heavy weapon from the Su-25T.....when launching a Kh-29T/L from one wing, you need to be ready to counter a very significant roll to the opposite side and adjust trim to compensate :)

That sooooooo rocks Alfa. :D

You will certainly have to figure that in, when deploying a weapon from an AFM aircraft! :) .....besides, the Kh-29 is a *much* heavier weapon than the Kh-25MPU, so even if they are launched from opposite wings, the Kh-29 will affect the balance more than a Kh-25 :)

 

I think many people will adopt a rather "wastefull habit" in Lock-on 1.1 ;) .....firing weapons in pairs, although not required for the destruction of the target, just to retain the balance of the aircraft :D .

Or maybe have to think out to make two targets shots... avoiding to engage one by one :wink:

Hehe...yeah it does :D

 

But the effect requires some getting used to.....as mentioned above, when trying to take out two different targets in a single pass, it is very tempting to launch two weapons against the first target to retain a stable platform for acquiring the second one via the Shkval TV :)

Hehe yeah, but in order to do that, you would need to pick two targets in very close proximity of each other and launch a powerful weapon for which the blast radius is enough to take out both at the same time :)

 

It should be mentioned that the weight offset is hardly noticable with light weapons such as the Vikhr....so when attacking e.g. a moving colum of armour, it is very easy to pick one target at a time and launch a single missile against it without having to struggle to keep the aircraft in balance :) .

 

I have developed a technique, in which I launch Vikhrs with a 2-3 second interval, and then move the laser designator from the first target to the next as soon as the first missile impacts - that is - while the the second missile is already underway :) . This cuts down the engagement time for each target (not having to wait for each missile to impact before launching the next) and you can take out a huge number of targets in a single pass :D

 

But it needs to be timed carefully.....if the second missile is fired too soon after the first, it will not be able to change course soon enough to chase down the new target :)

I didn't mean that, I meant in a strike "round", you would be advised to acquire one target, shoot it then quickly target and shoot a second (close enough to the previous one) not to make too much adjustments knowing the last shoot unbalanced your craft... It still means two targets=two shots, but I intended to notify that attacks would be twin-targetting sessions (a pair number in any case) instead of "who cares" ones. :wink:

 

And do you make a real difference between a full loaded rocket launcher and an empty one too? :)
