Yakovlev Yak-9T + NS37 Cannon

[Imowface]

Was having a bit of an argument the other day on 200, explaning to people that the NS37 could make acurate shots at super long ranges so I did some pictures for them to show how the bullets dropped and spread at various ranges





you will notice that there are alot more bullet holes then what the 9t carrys for ammo, I had set it to unlimited ammo in offline to test rapid fire, and just using single shots,
I hope these pictures help people see how great the NS37 is, and that if you can get used to it, the slow rate of fire does not effect you vs fighters.

Disclamer for these tests my convergance was set to 400, the reason I have it set close is that I have found in the MA that 650 may lead to problems hitting things up close around 200, as you have to aim low at that point

[Ruah]

its insainly accurate. . .and why are you on 200 arguing with some of these people anyway. . .bombing run in a 29?

[Debrody]

Heck it isnt!   just ask my 262 haha

Now in offline mode film shooting at cons with one shot only trigger taps. Watch how many hit but do no serious damage. Watch how close your shots come to the con but slip past. Repeat with the K4 one shot taps with the MK108. Fewer miss and more cause damage when they explode. It has seriously bad dispersion values in real life. Play your film back at x.08 to see all of this. NS-37 shoots like a lazer with minimum dispersion.

You will note that getting an explosion against the base of a fighter's rudder with the NS-37 has no effect. You have to weave from side to side and hit the upper part of the rudder from the side. Repeat this exercise but with an M3 on the runway. NS-37 slaughters the M3 and the MK108 takes a few rounds. NS-37 is alergic to aluminium.

In air to air with the NS-37, seems like you need a double or triple tap to kill things. At least offline in the pattern. The NS-37 HE round is the same as the Russian M1939 37mm manned ack HE round for killing aircraft. Should perform those one hit kills that our manned feild guns do. Single hit flash and the fighter falls to the ground.....

Playback at x.08 is long and tiresome. But, you will see some interesting things if you place your self just to the front side and above the target con and watch the rounds in slow-mo zoomed a bit as they come in from behind. Look for the round that hits dead center of the rudder's trailing edge and how neatly the tracer splits in half as the trailing edge cuts it in half. Saw those most often against K4 and G14 in the traffic pattern offline.

I have always maintained that the YAK-9T's 37mm is like a damn Laser...case in point, happened awhile ago but had a 38 BnZ me, miss, I hit rudder, pulled up and at 800 fired 1 37mm with the pipper just a tad above 38s nose in climb. 38 went poof and I went home happy. Great weapon!

I've been saying something isn't right with the NS-37 for years.  It doesn't seem to cause damage a portion of the time.  On some airframes (the 38 in particular) it gets great results with a hit.  On others, (Lancaster, P51) only certain shots get good damage.  I've hit a spit 16 4 times in the same wing and had it fly away fine.  Do that in a .303 armed bird, and the wing falls off.

I get the same feeling that the NS-37 HE is not on par with the mk108...hard to get any proofs

[Imowface]

I have never had a shot not kill a plane smaller then a heavy bomber, poof or no poof a ping still rips a wing off or explodes him

It seems counter intuitive while talking about this. We all agree that 880M/sec makes the NS-37 shoot like a lazer versus 500M/sec. But be honest. Have you ever gone offline and tested both cannon with single shots? Or if you have, did you hit the trigger and it was 2 or more got out then kaboom?

Fly the offline pattern and tap only a single round at a time from 200 while filming it. Say a minimum of 10 sec between shots to stay honest. I got more MK108 single tap kills/hits than NS-37 and the NS-37 shoots like a LAZER.... It's a long and boring procedure. But the slow motion(x.08) film playback is interesting. Just remember the NS-37 puts out 2 with tracer and one invisible. The invisible one makes you think the con does a delayed explosion or is so damaged by the previous hits that it blows up with a tracer passing next to its skin.

Yes if you double or triple burst per trigger pull with the NS-37 at 200 your chances of a single round hit is good. But, you can single round hit at will with the MK108 and it does not shoot like a lazer. Try the M4/37 in the P39. Funny how it single shots a lot like the MK108....

If I post my films it can reasonably be argued my results are due to my eye/hand specific coordination. If this audience each goes to the trouble of performing this testing then we have a tad more scientific set of observations to compaire.

[Imowface]

you have to remember, this isnt about anything more then the fact that it is possible to accuratly shoot to 1000 yards with this gun

[bustr]

I started out testing the NS-37 from the accuracy premise.

The physical results could not be ignored since the one shot issue is so intriguing. You are aware your dipersion value at 1000 is 70 feet left to right? Target=180ft, 9 rings 10ft wide. Thats not accurate at all even with an almost 40ft drop value. At 400 your dispersion is 20ft and at 200 5-10ft. But, your drop stays inside of 10ft 200-400 which makes the apperence of aiming dead on. Land and air engagement distances in russian testing of the NS-37 started at 400m and closer. In game thats suicide against a wirbel.

Try the MK108 at 650. You have to aim high by almost 50 mil because the drop is about 2x of the NS-37 at 1000. But, the dispersion is about the same picture as your 1000yd screen for a barrel only 23 inches long opposed to a nearly 6 foot barrel on the NS-37.

I just keep reminding myself this is a computer game and not the Anthony Chabot firing range near my house where my lookup tables from Hornady, Hodgon and Sierra make sense versus my target results.

.... never mind... stupid error on my part, wrong window

[Urchin]

As far as I'm aware, there is no inherent characteristic of barrel length that affects dispersion.

If both weapon mounts are stable, the dispersion would come down to some characteristic of the projectile.

[Charge]

"As far as I'm aware, there is no inherent characteristic of barrel length that affects dispersion."

AFAIK there is, especially in aircraft use. While a long barrel is better in providing flatter flight trajectory and higher MV it is also more susceptible to translate vibrations to dispersion, either airframe related or results from rapid firing.

Just a clarification if people tend to think that eg. MK108 is more inaccurate than Hisso 404 due to much shorter barrel. Physically it is not but due to other characteristics it is harder to gain hits with MK108 at long ranges so the choice to use a longer barrel starts to make sense despite worse dispersion.

[moot]

Wasn't it the MK 108 that went to a shorter barrel during development, due to some issue specifically with the original longer barrel?
