I am curious as to whether or not the Typhoon is modeled correctly. Specifically the amount of propeller torque. I realize that when stopped or during takeoff the torque effect can be huge, but it seems to me that in the game it's a little much.
During climb out at say 135 / 150 mph with heading and climb hold on, it still turns to the right. Look out at the right aileron and it seems all the way down. I would think this left hand turn position of the aileron should correct the torque (along with rudder input) but it doesn't.
Anyone know?
-
The short answer is it's modeled correctly.
Here's the take-off procedure from the IA & IB pilots notes;
(http://332nd.org/dogs/baumer/BBS%20Stuff/Typhoon1.jpg)
Also in the book "A Soldier in the Cockpit" Ron Pottinger talks about his time flying Typhoons during the war and he mentions having to use almost full rudder on takeoff.

thanks Baumer
This info would lead me to believe that, although the Typhoon generated a lot of torque, it was controlable. Did your book say that the airplane would still turn right even with flight control correction? ie. left aileron and rudder.
-
Its simple to correct. Just level off and build up more speed before hitting alt-x to auto-climb. The problem is you are depending upon auto-takeoff which gets you airborne sooner and easier I suppose but at a slower speed then the best climb speed.

That's true and that is what I do. But I was still wondering if the auto-takeoff speed shouldn't be effective enough for the aileron and rudder input to counter act the torque.
-
The auto-takeoff of every aircraft is lower airspeed then default climb speed. Just takeoff manually.
-
This is due to how the "auto" functions operate I believe. If I have understood past descriptions the control trim is read from a table of speeds so if you're flying at a speed that's not the same as the table you may "drift" due to being slightly out of trim.
In my simpit I have extremely sensitive potentiometers for my trim control, and I have no problems flying the Typhoon hands off, keeping a constant heading.
-
Baum,
Not to correct you but,(ii) clearly states"open engine to 2500 rpm,then clean oil off windscreen"!
I dont think HTC has that modeled,so I wouldn't say it's 100% correct...... :rofl :rofl :rofl
TBH,it's been awhile since I've flown the Tyffie,maybe after the latest update this was addressed.... :devil
:salute

This. Just build more speed before you hit auto-climb.
-
Previously, the trim tables for the Typhoon and Tempest were incorrect. The aircraft would slowly turn to the right as the Combat Trim wasn't applying enough leftward aileron trim at any speed. However, I thought that had been fixed.
-
I got a question about both the Typhoon and the Tempest. At just over 500 mph in a dive both planes automatically start to pull up. Less than that speed for the Typhoon. I can get a P-51D up to 540mph in a dive and pull out of it. With prop control I can keep it a 400mph for half a sector with out wep. In the off line area I like to see how fast a plane can go in a dive without failure of some type. Is there a trick to the Tempest to stop it from pulling up at 500+ mph?
-
I use a cruise climb of 200mph. Seems to maintain heading at that speed. :)
-
dot speed 200 works well for the typhoon

You can use your elevator trim keys: I and K. A little practice usually does the trick.

Its easier to avoid this problem if you use manual trim. You wont actually avoid the problem but you will be trimming as the transition occurs.

Many planes can use a faster climb speed with very little loss of climb rate. Unless you DON'T want to gain ground while climbing (enemy ahead, too short distance to target), climbing at 200 and even 220 in some planes (like Mosquito) can shorten the overall trip time. There is an added advantage that if you get bounced, you have some initial maneuvering speed to work with.
-
If you are bounced its a lot better to be trimmed for something within your cornering capabilities than below (especially).
-
The typhoon and tempest do suffer from high torque issues at slow speeds in real life but at high speeds above 250mph that is virtually gone with a little trim. I believe if i remember what i once read on it saying that this was to be a known fault during development and was to later be rectified with a small upgrade to the aileron movement range but as in testing test pilots easily found a simple way around it and that was as described in the takeoff procedure on page 1. And since it was urgently need in action the RAF said roll with it. its in the pilot logs so new pilots know about it :)
This was also a reason why the Tempest And Typhoon took on a more of a ground attack roll than dogfighting. As it had the ability to spin to the right through the propeller torque in a slow tight turn not what you want in a dog fight. :) But in low level high speed ground attacks they rule that department along with the P47 and P38 :)
-
Thanks for the information. I could not see how a Tempests could catch a P-51D in a drive when the nose pulls up automatically on the Tempests. while the 51 can do 75mph more in a dive without that problem.
-
Ah but remember the P51 may be faster in the dive but the temp and typhoon will out accelerate it in the dive due to weight. Remember the heavier the object the faster it accelerates to the ground. Do what i do i climb away from the temps typhoons as they get to 600 yards away from me and by the time they are starting to climb again im already diving down for the kill shot as they loose the speed advantage quicker in the climb :)
-
Really? I see so many factual problems with that post Im unable to decide where to begin.
-
will out accelerate it in the dive due to weight.
You never took Physics in elementary school, did you?

You never actually dropped something to the ground did you? WWII was not fought in vacuum, air viscosity is actually essential for normal flight. Though it is true that weight is not the only factor.

Though it is true that weight is not the only factor.
And hence, my statement stands.

Anyone have the frontal profile area for the Typhoon and Tempest? :D

Total BS. In a vacuum everything falls at an acceleration rate of 52 feet per second per second until it reaches terminal velocity regardless of weight.
Atmosphere introduces variances as do aerodynamics of the falling object and if it's powered or not among other factors.
Care to try again?
