Title: overboosting
Post by: Raptor05121 on June 04, 2011, 12:56:29 AM
just thought about this. most ww2 aircraft had some sort of forced induction, giving them legs at high altitude.

BUT, furballs rarely ever go above 15K, and as a private pilot SEL and experience in a M20F (turbonormalized Rajay), if you hit the boost too low you could blow turbo seals and break a lot more.

why is this not modeled in AH? such as flying NOE in a Spit, WEP boosted to 20+ pounds of boost (34 lbs true).

thoughts/comments?

i believe aceshigh doesnt model things like engine problems or stuff along those lines.

otherwise the b29's engines would be catching on fire and the 163's would be blowing up on the runway.  :lol

A good game for complex engine management is Il2 sturmovik. The flight models suck, though.

Il-2's engine management is less realistic than AH's.  They give you more buttons to press, but the behavior bears no relationship to real WWII engine management.

I believe HiTech said something about waste gates to avoid overboosting having been pretty much standard things on these aircraft.

There are a number of things not modeled in AH. Remember it is after all a game.
How many times have you been at altitude and then just chopped the throttle and dived for the ground. Every hear of shock cooling? Do that to an air cooled engine and it will lead to cracked cylinder heads.
They have to find a balance between realism and playability.

My opinion of course.

Only certain types of boost additives were for 30k+, and would damage engines below this alt. Unlike the horrible modeling in Ubisoft games, it would NOT blow your engine up in a matter of 2 seconds.

However, these planes had OTHER types of boost for below that 30k alt minimum. So below 30K you might use MW50. I'll use the german equivelant because the only thing I can think of that matches your description is GM-1, another german additive.

So up to and above 30K you can use MW50 just fine. Above 30K you can also choose to use GM-1.

AH just has it so that whatever that boost is at whatever that alt, you just hit the 1 button for it. You may note this also applies to takeoff power settings at low altitudes. They are enabled in the WEP power rating but then fall off above that to normal WEP settings, as in the real deal.


So it's all covered. Now, GM-1 systems are rare. Only one plane in this game has it, and there's some debate as to whether it's modeled at all on that plane or not. That plane is the Ta-152H.

No other plane in game sports this option, though they do have higher RPMs, higher MAP, water additives, MW50, and so forth.

All of those are added under the one simple key press WEP command.

I've wondered about things like that also. Another example would be high manifold pressure with low rpm settings. Or how about inverted flight. A real P51 could only fly inverted for about 7 or 8 seconds, but in this game they can fly all day long that way.

Inverted flight and stick stirring, neg-G flopping are all areas I'd like to see HTC look into some day. The short answer is "no" you can't fly inverted for very long. Some planes prohibit it for more than 10 or 15 seconds (something to do with oil draining, pickup, for the oil pump?) and the engine would sieze up from oil starvation.

Overall HTC does model and factor in a lot of the things you're going to ask about, but some things haven't quite been resolved yet. It's still the best game out there!

well, HTC has allready addressed the stick stirring problem, sort-of. if you move around too hard/much at once your plane locks up into a straight line and the message pops up "dont move your controls so violently".

only way to disable this is putting the plane in auto-pilot.

they just need to incorporate this for tighter movement.

That hasn't solved anything really. It still happens. It has lessened it, but because of the way the game "predicts" your heading then transmits it before you are on that heading, it won't change.

There are way too many variables in overboosting an engine to leave it in the hands of the pilot.

All it takes is a couple of milleseconds of detonation events to pop a boosted engine....which is faster than any human can pull back the throttle.
