Possibly Found a Bug about ShKAS ?

[Solmyr]

...Yak-1 (s69), I-16, MiG-3 and might be true about others weapons and so other aircrafts too. If ever you see where I did lose the common sense, plz let me know.

 

I was thinking about the ShKAS rate of fire : to me it was something like ~1800, and ~1625 maximum when firing through the propeller. Then I went into the in-game data screen, where I read 1800. Then I though that devs had chosen to stay with the optimal rate of fire indicated only, but the game still models the synchronized loss.

 

So I decided to test it in game (spring map) :

 

1) Yak-1 (ser.69) ; on the ground ; idle throttle and so idle RPM : In those conditions ShKAS heating grows slowly at continous firing, but still it needed to stop it from time to time, so I did with the timing also of course. Eventually it gave me ~700, which I found to be a quite expected number. (I'm not a weapons specialist).

 

2) Yak-1 (ser.69) ; auto-flying at level flight 2500m, full throttle and RPM : Full ammo fired without any overheating technochat message (was a bit surprised) and here is the calculated rate of fire : ~3500 !!

 

I love my Yak-1 whose fire power is quite poor yet, but this ShKAS rate of fire is about twice the expected number !

 

Anyone willing to reproduce the tests (and others) and/or able to help me to understand that before I push such a topic into bug report section ??

Question: How are you calculating the fire rate specifically? Using ammo capacity and fire duration? I'm happy to replicate the tests.

Here we are ! I was washing dishes when it suddenly hit my brain : I totally forgot to take into consideration that the total amount of ammo (1500) was for 2 ShKAS ! D'Oh ! I'm with stupid...

 

Still the number is ~1800, wich is supposedly the best rate of fire that the weapon could acheive if it was mounted in a wing, not firing through the propeller.. Or propeller at full RPM isn't a problem at all maybe ?? Could devs have a quick word on this ?

 

So the worst rate of fire wasn't ~700, but only ~350... Well, it's a huge loss of rate of fire !

Yes, it's not perfect calculations, but still is pretty accurate enough.

So 3500 is 1750 per gun.

 

If you turn your engine off and still hold the trigger you can see the guns rate of fire slow down until its shooting as the prop passes it.

 

Its one of those little attention to detail things

I'm not surprised, that you got close to the maximum rate of fire possible, but I am surprised that the rate was so low at idle.

 

WW2 era synchronizers mostly give off 3 or 6 firing impulses per prop revolution (WW1 era ones normally only gave off one) so even at low RPM there should be plenty of impulses to sustain a pretty good rate of fire.

Doing further tests, I'm quite confused now   :

 

Still Yak-1 (ser.69) ; 40% throttle ; 100% RPM :

 

- In the air : ~1800

- On the ground (brakes hold) : ~1000

 

Why this difference ??

[=TBAS=Sshadow14]

100% RPM does not tell us much..

Wat is the actual RPM while say on ground like that versus flying.
in RPM not percentage?

all 100% RPM fire rate in dive will increase and in climb with decrease.
the engine adjust pitch to TRY maintain the set RPM buts its far from perfect.
Eg, Set 100% RPM @ 100% throttle then pull power to 0% fast then back to 100% fast watch RPM go all over place

So try test at a specific true RPM..
Say 2,000 on ground, 2,000 in air Regardless of speed/power
