MiG-15 undermodelled ?

[Sokol 444]

Hi,

after the release of a formidable set of MiG-15-camos i tried to recreate Korean fights against B-29 - no chance. i was flying at 14.000 meters, the bombers at 10.000 meters and some 10 kilometers away, their escorts at 12.000m. and i could NOT CATCH up - they simply evaded, flying nearly as fast as my jet fighter.

 

any idea ?

I don't know if the same is hapening to you. But Some time ago a similar thing hapened to me with a diferent set of airplanes.

Turned out I was flying with a to high AOA and my engines just didn't have the power to accelerate at such a high AOA at that alttitude.

What you have to do is drop nose gain speed and as you climb back up do it slowly so your speed stays up and your AOA low.

Once again this is a sugestion your problem may be entirely diferent.

If you check the data.ini for the B-29, you'll see this in the Flight Control section:

[FlightControl]

StallSpeed=45.13 100.9mph

CruiseSpeed=135.92 303.8 mph

ClimbSpeed=208.85 466.8 mph

CornerSpeed=75.54 168.9 mph

MaxG=3.00

MaxSpeedSL=257.05 574.6 mph

MachLimit=0.80

PitchDamper=1.0

RollDamper=0.5

YawDamper=0.05

 

I believe, if I remember correctly, that these figures are supposed to be in meters per second, which means the B-29 is capable of over 570 mph. I think that might be a tad high..... And I don't think it could maintain a climb at 466 mph. Might want to fiddle with these, if I am correct about their being in meters per second. Someone correct me if I'm wrong. That is one hot ship for a bomber...

Your quite right fellas. The whole Strike Fighters game engine is all wrong for early model jet and prop aircraft. The stock game engine first of all models aircraft with afterburning capability, and the fact that all aspects of flight happen at 20,000 feet or below.

 

The game drags the aircraft around a high AOA parameters, behiend the power curve so to speak.

 

Here is a tweek for you. It works quite well for Korean War era aircraft

 

First you will need the Extract Utility aviable here.

 

Second ; go in what ever game your playing. From the Flight Folder extract the MISSIONCONTROL.INI FILE.

 

Third open the file.

 

Forth; copy and paste this entry

 

 

[Altitude]

Normal=12190

Low=500

VeryLow=100

High=12190

VeryHigh=15240

 

[Waypoint]

TaxiSpeed=5.14444

TaxiTime=0

TakeOffTime=0

InitialClimbDist=3219

InitialClimbAlt=1524

MaxInitialClimbAngle=15

MarshallTime=150

IPDist=27780

IPAngle=45.0

IPTime=120

AttackAlt=500

MaxApproachAngle=359

LandApproachDist=16090

LandApproachAlt=3048

LandLineupDist=9260

LandLineupAlt=762

StackAltDiff=500

ArrivalTimeDiff=60

EscortTimeDiff=10

MinBaseRange=30

MinFACRange=15

AircraftWaypointSize=1500

GroundObjectWaypointSize=500

 

Close the MISIONCONTROL.ini file and save the changes.

 

This tweek loosens the reins so to speak on your aircraft and the waypoints are generated at lower AOA angles.

 

If you do not enjoy this tweek simply delete the MISSIONCONTROL.ini file and the game will revert to the "stock" settings.

Yeah, these values are meter per second. 570 mph? Sounds like somebody mixed up mph and km/h.

The top speed of the B-29 (and I guess that was not acheived at sea level) is around 360 mph (which is about 570 km/h).

To sum it up, the B-29 is indeed totally overpowered. Too much engine power (each engine is rated at 3245 kW, in reality they only delivered 1620 kW) and wrong speed values. Still a nice model, though.

The data.ini file for this aircraft is incorrect.

[+Dave 2,322]

a 570 mph B-29....... WOW! Now no kidding here, watch a show last night about how the B-29's were get caught in the jet stream while on missions to Japan. THey said speeds up to 450 to 500 mph by being the stream. That is amazing. Then they said the opposite would happen at times and they would be going against the jet stream and crawling along at 300 mph or less. Taking alot of fuel and time to get to the bombs runs.

[Wrench 9,848]

Always knew it was a bit too fast...try catching one of them Tony or Zeke, and you'll find out!!!

 

Don't forget too, that aircraft hasn't had any updates since Patch 2 for SF, 4+ years ago.

 

Good find on the data ini tweeks...these should go in the KB...in the ini tweeks listing thingy. Useful for the TU-4 as well

It would be better if they were updated and re-uploaded.
