CFS3 vs Il-2 FB

[BEAR_-_AvHistory]

605 Scorpion,

The 1% visual was created by Josh ZUYAX Ziebarth as were the other AvHistory Hurricanes err Spitfires.

nickle,

264mph is pretty fast for a climb speed in a WWII aircraft.

Why not use the 164mph IAS of the real aircraft?

But hey, the quoted numbers are BS anyway. In 3 minutes the 2400ft+2300ft+2200ft=6900ft, a little short of the 10,000ft climb request.

In level flight at MIL at 10,000ft the P-47 just barely gets up to 318mph IAS (359mph TAS), not leaving much excess horsepower room at 264mph IAS.

So you are correct.

Bear, when are you guys gonna release those Hurricanes and that Avenger???????

Pg281 America's One Hundred Thousand shows the P47 Speed and Climb Performance.  Speed is in TAS.  I converted to IAS std day.  TAS 10K is 365 mph in the climb.

Bear: climb the 47 to 20k on your schedule and post the airspeed and r/c at 5k increments and time.  See if you can beam yourself to 20k.

The published schedule is optimum and will give the best climb performance.  It is not the schedule used operationally.  Normally the fighters took off in sections and divisions.  Rendevouz then climb with several divisions of 4 each squadron.  Speeds were much less to keep the flight together.

I noted during a prop flight in COF that when the  mixture was accidentally substantially reduced that the engine sound and air speed picked up significantly.  Reduction to engine stumble then to smooth then a few clicks more gave better power than did full rich.

I tried this in the 47 mil power in the climb.  Retard mixture to engine stumble, smooth, plus a few clicks gave best power.  Not the way it should work but helps.

I note that cfg shows 47 with supercharger.  Should be auto and I find no way to key on.  Manifold pressure was steady 53 inches during the climb but only went to 15k.

The Hurry's will start to come out soon, but there is no Avenger planed for CFS3 short term.

Next out today or tomorrow will be a Yak-9M in

Interesting thread guys!

My 2c worth, CFS3 over IL2 / FB any time! despite CFS3 running like a dog 8 out of 10 times I try it (The other two times it simply rocks! (?) )  ::)

I'm puzzled to hear of people having problems with IL2/FB - they've always ran fine for me even in my Celeron 700mhz days.......  :-/

Ran additional climb test 47 from 10k to 20k.

Mixture lean to stumble at mil power then run smooth results in significant increase in climb performance.

Still poor 47 climb performance.

USAAF specs 4 min 10k to 20k full fuel and ammo.
These were performance tests running the engine at mil power.  Not operationally permitted for normal climbs.  

Mine was 9 min (8:55) 10 to 20, 50 pct fuel.

Ability to climb is a critical fighter characteristic in a dogfight.  Mil or WEP power is used as necessary.

For test I set elevator and aileron sensitivities to 0.950 in cfg from 1.000.  Target r/c 1500 to start at 305 IAS, 10K.

I don't use auto mixture.

>>>sorry, but that's getting silly.<<<

Agree, maybe someone else can do "fuel mixture vs altitude 101" for this guy but as of now I am out of here

I tested the 47 at 169 mph climb 10k to 20k. Rate of climb was 3000 plus fpm.

I checked on line for another climb speed chart.  Confirmed that 169 mph is ball park.

I reviewed America's Hundred Thousand charts.  The TAS shown are only for Vmax reference.  No climb speeds are shown.

Bear: You are right; my P-47 climb statements were wrong.

[nickle]

After several AI encounters 1v1 P47 v 109/190.

Neither are much of a problem.  190 easiest of the two.

I changed my Energy tactics based on the 169 climb performance.  I want E for manuver but know that the 47 has good performance at 169 if out of E.  

Setting the Mix to lean plus a few bumps is a significant performance increase. One encounter the Mix was too lean and engine wanted to cut out.  Bump up and reset.

Combination makes the Truck a very good sim dogfighter.  

Makes me happy.

Nickle,

No Problem.

Inspired by the performance of the P-47, I downloaded the BR F4U.  

Wow: None of the nasty stall habits of the CFS2 versions.

Very nice flying machine.  

Takes more turns vs the 109 because it doesn't have WEP.

Good machine

For a really depressing 47 performance chart:

Note the Climb recommendation a/s and r/c.

The 47C first saw combat Europe in April 43.
47D in process of replacing C models July 43.
Water methanol injection D's begins Nov 43.
Paddle prop install begins D's Dec 43.
Ongoing in April of 44.
Combination gives performance equal to 190 below 15k.

Nov 43 P47 overall kill rate Europe was 3 to 1.
For comparison the F4F vs Japanese was 9 to 1.

May 1944 Maj Gen Kempner states that 47 broke the back of the Luftwaffle.
