To much blade flex it's been awhile since i've flown the shark and I remember Blade flex.you can read:book: about in lol I wont say it..:D:smartass: I see it's your 1st post:cheer3nc::cheer3nc::animals_rooster::animals_bunny::clown_2::prop: Welcome to the Farm..it happens when you push the bird to hard to the rt most of the time...I think..i'm old..:megalol::thumbup:

Hello folks. I've been flying around with this sim for a couple months now and have been starting to get somewhere with it, but every once in a while I still get the odd instance of my rotors nailing each other and I'm not really sure why.

 

In this instance, I was basically flying in a straight line. If any kind soul has a minute to look at the track and explain to me what flight parameter was off enough to cause the issue I'd really appreciate it.

 

essentially you're flying it all wrong, you need to trim the aircraft and be gentler. you're pitching all over the place.

 

in particular, "safe practice" is pick 2 of 3:

high forward speed

full throttle (for climbing)

maneuvering

 

if you pick all three you will occasionally die.

 

tl;dr you're doing it all wrong and have maxed collective the whole time. keep collective 80-90%, stop pitching all over the place, fly slower. pick 1-2 of these and you'll be fine.

 

i should mention that you if this is average flying for you you really need to study up dude, it's pretty terrible. i don't think you trimmed the aircraft a single time, and in the ka50 that is a mortal sin.

You pushed it too hard, when I've seen the blade angle constantly at 15 dgr. I knew something bad would happen...

Also you should trim more often :joystick:

Not flexing, flapping. The advancing blade is going faster through the air than the retreating blade. More speed means more lift, so the advancing blade flaps up to reduce AoA (and therefore lift) and the retreating flaps down to increase AoA (and therefore lift) until both sides are even.

 

The faster you go the more this happens. And in the KA50 because you have twin rotors going in opposite directions, the down flapping blade on top is the same side as the up flapping blade on the bottom.

Just look up retreating blade stall.

As everybody else said. Pushed her too hard. If you go over the speed limit, that would happen. If you fly fast, above say 270 kmh, you should be especially gentle with cyclic and rather lower collective than increase it, but also gently. Since it's a game, you can freely test the maximum flight/control envelope and learn what she can do, and what you shouldn't do.

 

Ka-50 is an awesome bird, but it has her limitations. Just fly, enjoy and experiment. And never give up ;) .

 

BTW, in level flight I usually fly at 302 or more kmh. Anny sudden change in pitch (or too big pitch) or collective at that speed causes instantaneous rotor collision and a back pain caused by an immediate ejection ;) .

Nevermind.

Are you kidding? What a selfish editing is that?

Should every user do that when get the answer or solution?

 

I don't believe this... >:(

I personally have noticed if you are pushing your Shark harder for a longer period of time it damages the blades. So if you were IAS MAX for a long period of time and then ease off you are still in danger of blade failure when making a normal manuever.

 

I have also noticed, if you have your engines maxed out, eventually they will fail or catch fire.

This has been argument unnecessarily number of times, you push hard she will give you risk.

 

I'll add something more check the wind!

Don't add 8m/s wind from lateral to front when you are > 300 or she, the black shark, will complain a lot...

The Blade which runs into the Wind flow will always create more lift and is more reponsible for steering inputs than the Blade which runs out of the wind flow.

You have it also translated? Otherwise not mch.

 

 

edit

 

OK I translated it (hope okeish... still missing a word [ЛеTньIх], summer? Warm air? Periods? :) )

 

 

 

 

 

 

So the minimum distance in level flight is 850mm? So they clash when abrupt changes in attitude are made at extreme speeds most probably while fighting the AP and trim.

Nonsense. The advancing blade flaps up and the retreating blade flaps down; this largely eliminates lift asymmetry.

 

As for "more reponsible for steering inputs"... huh?
