Dirty Rotten Flieger

Hi I am wondering about Daimler benz engine and max power versus RPM Take for example the 2400rpm limit in a bf109E3. Does this mean that if you rev the engine to 2600rpm for 30sec that you are getting more power or is the power plateaued or is the power dropping off after a peak at 2400rpm? I am asking because I have been thinking that under circumstances of low IAS it is useful to rev the engine to 2600rpm for short burst of acceleration. But if the engine does not make more power at 2600rpm than at 2400rpm then maybe I am mistaken. It also occurs to me that the prop pitch is made very fine while reaching 2600rpm and at low IAS this may be giving improved acceleration even if the engine is not producing more power. Any Daimler benz engine experts who would be able to offer some insight into this ?

Wing glove vanes are extremely cool. Hope they make it in at some point.

Interesting story. Must have been quite embarrassing for the poor guy, and also quite a surprise the moment he was ejected while not expecting it! lol

I have the brake lever on the cockpit flight stick bound to an analog stick on a dualshock controller. I can see the needle on the dial move slowly up as I pull the analog stick. I can hold a third braking strength while I taxi which gives me enough braking to steer but not so much I stop. So it does work correctly. Maybe you need to play with the finetuning of the curve to get it working like this. The spitfire in CLOD uses the same braking system. pneumatic brake lever on stick and rudder releases oposite brake turning plane to direction rudder is turned.

I just bought the K4 on sale and I am pleasantly surprised. I didn't enjoy flying the dora when I couldn't balance the ground trim tabs for balanced cruise and I was expecting the same problems but the K4 is perfectly trimmed to climb at around the range of 400km/h, 1.4ata, 2500rpm . which feels great in a plane that out climbs it's opponents. Really a joy to fly... If I can get off the ground . Love the sound of the beefy engine. I noticed the leading edge slats deploy at much higher speed and lower angle of attack than I expected. I imagine this is increasing lift and drag at speeds when it is isn't needed. I don't know exact speed but they pop out closer to 380km/h than 250km/h which was not what I would expect. Maybe my expectations were wrong, but I thought the slats were just for close to stall speed. Not nearly 400km/h Anyway great plane, and beautiful model. Glad I bought it .

Mig15 control reverse at transonic speeds so just Bnz him at hi speed. he can't follow you at all. on the other hand Mig15 is awesome at slow speed loops. Don't slow down and play his game

We have been typing to each other online. " I'm flying in the contrail down the coast" Meet your opponent in the contrails. In real life the Mig15 had very little smokeand hte Sabre had visible smoke exaust. It is like this in the game and I many would hate to see any less than historical. The DCS visibility problem maybe will be fixed in EDGE.

In DCS spotting targets is extremely hard and the overdone sabre reflections makes it almost impossible for me. The mig15 reflections don't seem to be as bad. Maybe it is a communist plot to give the Mig15 pilots the advantage!

We were playing on the server the other day and it was great. Dream come true to fly the mig and sabre online versus, with DCS detail. Spotting targets is crazy hard in DCS though. We were typing to the other team to meet us in the contrails flying up and down the coast. If you are over the water when the fight drops to the deck then this helps too. It works fine for duals but when I first took off and tried to find my wing man I was thinking this is just unworkable. Way too hard to find each other. I guess the ground targets would help a bit too because you know where the target is so you know where to go to look for enemy.

I think you may be referring to the guncam. It is a little black contraption mounted on the right of the HUD with a little arm for the lens leaning toward the centre of the HUD. There is a switch second last from the right on the bottom row of the black switches on the right side panel. It is actually the last black switch and there is a white one to the right. You can flip the switch and the camera will appear. Flip it again and the cam is gone. I just leave it off for the clearer view.

This is interesting. I'm trying to understand it. I think the basic idea is that when two objects are on a collision course, the angle of line of sight won't change. So if we are both flying jets and on a collision course and I am looking at your jet my head won't turn. I'll just keep looking the same angle till we hit. Maybe it's as simple as that? If the seeker sees the angle is changing it alters the flight path so the heat source stays in the same angle off it's bore sight. Gee that seems a lot simpler that I expected it to be. Maybe I am forgetting something.

I was sure this was a bug when I saw the HUD repeater! Not having the plan view of your radar is not very nice when you are used to it.

What does ARU stand for anyway? Yeah you're right. I turned the ARU off and manually switched it to slow speed which should be the most sensitive elevator setting and I still found it hard to stall or get AOA into the red. This would suggest that the maximum elevator deflection has been reduced. As long is it is more realistic now...

Oh those graphs are great. That's what I was trying to get at. There is much less of a curve for M/TAS than M/IAS so TAS is a "less wrong" indicator of M number than IAS and that's why they say to use it.

Gee I'm really surprised that the manual says to climb at constant TAS. I always look at IAS for climb. But then it occurs to me that climbing at constant TAS means roughly constant MAch number. I think? So if you're climbing with tanks and missiles then you wanna climb to 10km at subsonic speed cause the tanks will not let you climb supersonic anyway... Maybe this is why they say to climb at constant TAS instead of IAS?

Well I guess the ARU is performing it's job... But I kinda miss being able to ride it on the edge of stall. It loses in absolute maneuvering performance but it gains in pilot confidence and aggression. Now that I think about it, it wouldn't make much sense to have the ARU installed and still let the pilot override it and lose control of the plane. You would think that we could just disable the ARU and exceed max AOA though.

I just ran some tests and yeah about 1300km/h IAS or Mach 2.1 seem to be the limits. I tried running the burner at 700c at about 15km alt and I still reached 2.1 M and the engine shut down. So it is not overheating. Below 5km alt with the 2nd burner activated the RPM goes out of the yellow range into the red but the engine doesn't shut down so it seems to be normal to redline it with 2nd burner active. I was expecting to over rev the engine but as you guys have suggested maybe it is the supersonic intake air that causes a compressor stall? I restarted the engine many times so it doesn't appear to break it but it may be causing acumulative wear. I did eventually find myself unable to restart but I am not sure about the limitations on restarts. Maybe there are other factors? Also the airframe over speed limits have been removed but I have been unable to get above about 1400km/h IAS and have not seen any damage to the airframe. PS I think there may be a time limit on AB as well now. I think I may have had a couple of shut downs from running it too long.

Oh I was only joking. I like to think of the Mig15 as the underdog. Compared to the Sabre it seems a little primitive but in a good way!

I am sure I have heard of Mig15 flying too high for the Sabres to reach... I tried to find out how high I could fly in each. The Mig was quite hard for me to reach 16km alt. The high mach and low IAS was close to the limit. I lost control at least once from hi Mach in the Mig. But the Sabre easily climbed above 16km without any trouble at all. Is this because we have the later models? Maybe the first versions of each plane to see combat had different ceiling performance?

I thought the engine sound was too soft in the cockpit. I have to turn the volume right up to hear it and then if I hit external view I wake up the neighbours with the sound of a screaming jet engine at 2am...

you can use it the whole time. I imagine the only reason to turn it off is if your engine is out and you want to save your hydraulic pressure to lower your landing gear and flaps, and so you wouldn't want to use up the pressure in the system maneuvering the plane as you flew toward the airfield...

When ever you do a quick mission with a plane that uses ground power, you have to open the editor and make the airfield blue or red. ( same side as you) Then you can use ground power, load ordinance, or repair...

oh good to see Bunyap. Your Sabre vids were great

Seems to be some conflicting info on ground power or no ground power... I can't get it started without ground power

Sounds like you used the burner Northman? Also OP should be aware that angle of attack in also important. It is possible to fly with high angle of attack which slows you down a lot and prevents you from accelerating to a higher speed where you can lower your angle of attack. There is some feedback. Faster you go less angle of AOA you need, which enables you to go faster...
