Title: Prop Gripe
Post by: Hangtime on May 21, 2000, 02:59:00 AM
Hang shuffles slowly into the O club. He seems to be moving somewhat slower than usual towards the bar. With each step comes a rumbling clatter. Behind him, seemingly by magic, tables; patrons and chairs are dislodged. The further he comes into the darkened barroom; the more pronounced the mayhem in his wake.

He reaches the bar... and the commotion seems to stop. As people pick themseves up and return the chairs and tables to their upright postions he orders a bud; takes a long pull on the tallneck and with a noticeable sigh of relief returns the empty to the bartop.

"What in hell is all the commotion about; Hang??" asks the barkeep; replacing the empty with another. Hang gratefully accepts the fresh bottle, takes another marathon pull; returns the empty to the bartop.

"Well; I stopped by the BPO's office. I griped about the usual stuff, got the usual answers. Nothin new; nothin changed. Unhappy with the status quo; I decided to up the ante and reopened the prop drag issue."

"Yah??.." sez, the barkeep; dropping a third bud within easy reach. "...and what did he say???" Hang again raises the the tallneck; again quaffs the bottle in one long pull. "Well, he said nothin at first, and then when I hollered about not gettin near enuff practice with prop drag enabled; he got a mite more annoyed than usual and then decided to help me out with it. Said I'd get a special demo immediatly to get a feel for the speed reduction and energy losses associated with prop drag. He hooked me right up. Impressive."

"How so?" asks the barkeep. Hang muses; motions for another tall neck "Well, the 5 minute walk from the BPO's office to here took twenty; and it's gonna take at least a 6 pack to restore the energy losses."

And with that; Hang turns around; bends over and picks up a Hamilton Standard prop; shackled to 15' of chain terminating at Hangs left ankle and drops it all onto the bartop. *WHUMP*

"..and ain't THAT a drag. Gimmie another."

I know you guys have been working on this thing non-stop and need a break, but...

Some thoughts...

You know, maybe when we get there, the F4 will have a more realistic tourque (nah!) and these otherwise dweebs would get scared away from it  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

I think that one F4 should be able to take 1-2 tanks (my opinion here), but not the 6-10 (easy) that it can take now. Give the ground guys some time to work 'em down and get some hits on 'em too.  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

The C-47 is way too easy to fly. It feels like a J-3 Cub more then the bus it was.

The 109 cockpit has way too much visibility.

Could we drop every part of the icon except the country id (bishop,rook,knight)? Range and type being determined in situ? SEA?

Fix the MA so that A1 ain't no more.  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif) A big lake in the middle would be cool  (http://bbs.hitechcreations.com/smf/Smileys/default/wink.gif)

Great story Hang  (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)

Voss, I've heard many stories about F4u's having the problem of flipping on to their backs if full power was applied.

this is due to Newton's Third Law of Motion which states that for every action there is an opposite and equal reaction.
An airplanes propeller rotates in a clockwise direction(US). This produces a force that tends to roll the entire airplane counterclockwise about its longitudinal axis.
Torque reaction is stronger when power is significantly advanced while the airplane is flying at very slow speed.

I've never been able to duplicate the entire plane being torque rolled from a standstill in AH though.

btw:

torque is made up of 4 elements:
1. torque reaction from the engines propeller
2. corkscrewing effect of the slipstream
3.Gyroscopic action of the propeller
4.Asymetrical loading of the propeller (P-factor)

however gyroscopic precesion isn't modelled in AH, but that should only cause a problem when the tail is raised after you start rolling.

ok back on topic...
prop drag and the ability to feather individual engines after it is implemented will be a great addition to the AH FM and will affect tactics nicely

BTW Cit, #3 includes the inertia of the prop plus all the rotating goodies in the engine, gearbox, accesory drives, etc.

I don't fly the F4U that much, but I seem to remember that if your on final at stall speed and you punch the engine up to WEP, that it will roll over on you if your not careful.

I know the Pony has that tendency.

Oh yah.... Bring on the Prop Drag  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

I concur with Vermillion.  There are several planes that will flip you right on your head if you are clumsy with the throttle on approach.

The only 'careful' that would prevent the Hawg Flop when in landing trim is very slow advancing of the throttle.  Firewall it from a low power setting at low speed and you're inverted before you can blink.

There are very good reasons why, among it's many nicknames, Ensign Eliminator was one of the first ones it earned

Consider also the effects prop drag and torque should have on FLIGHT.. in the vertical, near the stall, hanging on the prop.. in the descents when the throttle is snapped closed.. speed control; roll control. Gents, drag, gyroscopic precession and torque is a weapon!!

The ability to use the idle propellor and its associated drag to slow the planes in dives is the single most glaring absence in these FMs i m o.

Add the correct engine torque values by all means.

I want AH FMs to be superior in all aspects!

How about F4u's then, I have no trouble with 6 view after I adjust views a bit... or spitfire... or C.205.. or.. so on.

IMO, 109 has worst visibility of all AH planes, thats for sure  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

Heheheh Voss I don't know about the f4u but I do know about the gooney I logged alot of hours in one while in the Air Force and believe me they fly themselves they were a dream to fly so the model here is not far off.

BigJim

It might be easy in the real world, but this thing flies itself! I think HTC made it easier then it should be in order to let dweebs have a role in field captures. I can't believe a stall turn at 1k would be surviveable in a real 47, but I do it all the time here.  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

I don't want to take anyone's fun away. I just think this plane needs a few more risks  (http://bbs.hitechcreations.com/smf/Smileys/default/wink.gif)

Voss, clean the gunk outta your ears.  A guy who flew the damn thing is telling you the model is right and you ignore him...  Geezus...

Post by: Voss on May 22, 2000, 12:24:00 AM
funked, re-read his post. He didn't say it was right. He said it is close. I *know* that a real 47 can't do what this online version can. Perhaps the man that has flown one in the real world hasn't exceeded real life limitations in the game. AND dropping troops in the vertical just would never happen...

Get my drift?  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

If it stays the same it's not going toi hurt my feelings. I just want a tougher environment overall. Fun, ease of play, dweeb planes, well I guess if you gotta...

I was getting ready for a drop the other night when I got a six call... I checked behind and sure enuff a hawg was roarin in for the easy kill. I stabbed the rudder; rolled hard with it; pushed in full down elevator as she got inverted and the hawg roared thru; blazing away with all them cannons.. and missed me clean. I finished the roll by feeding in top rudder; opened the door and kicked out the drunks.

Dunno if it was a historicly accurate move... but it worked.  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

I'm gonna have to go with bigjims opinion  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)
I've talked to c47 owners that have flown in to the airport I fly out of.
the goon was a sweetheart airplane.

after all we fly the c47 with 25% fuel.

and any plane can go vertical if it has enough power and light enough, even a 172 which by the way can do a great hammerhead  (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif) (heheheheeh)

just got to be gentle with it  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

Citabria, please become a pilot for a major airliner.

Then, the first and only time I am on a flight, I am sure I'll hear "ok, passenger dudes, check THIS move out"  (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)

Dead right Yeager, but perhaps even more important in vertical maneuvers.  How many of us have gone up into a hammerhead, tried to reverse quickly at the top, only to find we wallow at the top and can't quite get the nose around as we would like it?

Introducing prop drag would mean that when pointing straight up, closing throttle would act like a big air brake, slowing us up quickly and allowing for that fast hammerhead reversal.

Now if they could just get the long range gunnery fixed this sim would be perfect  (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

Sorry, Cit, but I think you have misunderstood me. The 47 we have allows a pilot to fly vertical, or even upside down, while he is dispensing drunks. Is it Pez, or is it Goon?   (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif) Cripes, tonight I'm gonna do the outside delivery again, and record it just for you.   (http://bbs.hitechcreations.com/smf/Smileys/default/wink.gif)

after seeing footage of a 707 doing a barrel roll I don't discount any aircraft from getting in an unusual attituds  (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)

Post by: Duckwing6 on May 22, 2000, 04:12:00 PM
Basically every "airworthy" Aircraft can do an aileron roll .. -> see the 707 mentioned above .. not that everybody CAN do it tho (Tex Jhonson could .. that Lufthana dude didn't)

Regarding the HOG's Torque .. the unfamous Torque rolling to inverted came from a lot of balked carrier landings, where you're basically in a stalled or almost stalled condition untill you slamm throttle .. then you have full ailerons and rudder to counter torque.. AND you have slipstream on your wing and rudder... makes for the perfect stalling of the left wing .. and off you go..

also a lot of them torque rolled when pulled off the ground when they were not quite ready to fly (speed too low again).

There is people who kill them selfes in C172's after a balked landing when they firewall their whopping 160 Horses and loose controll with full counter roll controlls ..  

But NO HOG would have flipped inverted from standing still .. ground looped or put on the nose yea that you can have ..

 Freind of mine is a pilot and a skydiver. He used ta tell me stories of co-ed naked skydiving into a state park. He had a park ranger hassle him about drinking in the park, so on the next flight(he being the pilot), he rolled on his side, slightly nose up with the door open and emptied about 5 cases of spent beer rounds across the park(for eviro/greenies, this was early 80's).
Needless to say, the ranger was not impressed. All in a C-47!

No this is very wrong, Torque is made up from arms,legs,torso and a head, just wanted to clear that minor issue up.
