Ataque a pistas

Post by Daisan » Sat, 27 Oct 2018, 19:51

Leyendo cosas del libro que subí hace un par de días sobre ataque a pistas, que hacemos según la tradición falconera, pero que hacemos mal...
Pag9
He stated that
the highest probabilities of cutting runways are achieved by attacking
perpendicular to the primary axis of the surface. This was verified by
Douglas (15). However, the number of craters on the runway is optimized
by attacking along the axis of the runway. Aircrews are reluctant to
, use this approach because of the chance of missing the surface entirely
on a single pass. If an expected value approach is used, these.
occasional misses are overshadowed by the large number of craters which
can be produced by passes which do hit the runway. Of course, all the
*"impacts could lie on one side of the runway, ailowing enemy aircraft to
use the other half.
Pag 10
Whitehead stated that the best compromise between
"the con~lictinS goals is to attack at an angle of 30* relative to the
runway axis. This work is exceedingly valuable,. However, optimal
"4' aimpoints and attack paramieters (other than the axis of attack) were not
4. ,* mentioned.
Pemberton (43) assigns aimpoints for perpendicular runway cuts
* using set theory to find an "'open"* cell by means of discrete
.. approximation. This wartime tool is-designed for fast execution and
addresses only precisions singly-released weapons.

Guay Diego, lo tendré en cuenta para esta misión. Gracias!

De BMS, por alguien autorizado ( piloto de M2000)

In BMS as in real (but I do not have real life values) BLU107 need to be dropped at a certain speed and at a minimum alt allowing chute deployment, and rocket booster ignition ...etc... in BMS values are around:

@ 420kts : 600ft/AGL minimum
@ 480kts : 700ft/AGL minimum
@ 540kts : 800ft/AGL minimum

With a +10kts margin.
Penetration velocity is achieved by rocket-boosted kinetic energy. It is designed for level delivery at 250 feet AGL and fore release speeds up to 620 KCAS
My advises.

- Drop bombs in PAIR. with a small interval (around 50ft - 100ft max)
- Do not attack on RWY axis but under 20 to 40°.
- Better aim intersection of RWY and taxiway.
- Altitude should be enough to allow chute deployment and rocket ignition. (Around 1500ft AAL)
- Remember to set a compatible arming delay and fuze.
- Concentrate on one section per a/c.
I did the research about the real weapon and if you want to use it BMS the most realistically these are the delivery parameters:
AD 1.50 sec
200' minimum height
550 kt max speed
I've found CCIP does "center stick" for all cases except 2 bombs (where first bomb is on target and second is one spacing later). Dare I say proper Durandal use is to consider the runway width. If the runway is 150' wide and you cross at 45° angle and 150% coverage that's 318' from first to last bomb (64' average spacing). On attack target the blob centered on a taxi/runway intersection and really nail that one spot.

The way the AI employs the weapon is correct provided it's from a good angle. Come in diagonally and release at a dense spacing that ensures at least 4/6 hits. Three pairs at 75-100' is good. The one bomb per tile down the runway thing is video game nonsense.

I think the GBU-31v3 is the best. It's a large fixed objective with a lot of attackers over it at once. Laser is messy, less standoff, expensive, slow, needs LOS, and needlessly precise. Unless there is a FAC on station and some desire to be picky at the time what targets to hit then go LGB. But if you have the security to conduct that, don't blow it up and capture it intact instead. Treetop level would be Durandal and Paveway III.
Main reasons why they do not proceed this this IRL:
- Most of air defences (mostly AAA like ZU, ZPU, ZSU ...) are near runways axis. Being the first or not do not change a lot.
- In case of Xwind or not perfectly aligned attack heading (not necessarily that easy IRL ... or because of possible defensive action just before arriving ... or for any reasons you can't PERFECTLY line up early enough ...), or bore-sight issues ... or ... if you miss your pass, you have a lot of chances to miss the entire pass and all your bombs might hit off the runway (too bad for a soooo risky mission).
- Most of the time, aim is also to hit the runway access => taxiway/runaway intersections.
- Because dady said that it is bad.

Some test made. The bombing of the photo was with the following config: 480 KIAS, 700ft AGL, 6 SINGLE, DIST 80 ft, RP 6 , AD 1.50 s. AIM to the center of runway. 30º Deg Offset

Ha abierto un hilo interesante al respecto en BMS

https://www.benchmarksims.org/forum/sho ... ot-Weapons

pero más interesante es lo que ha subido uno de los que estaban por allí, del USAF Fighter Weapons review
