The greater induced flow will change the AoA pushing that TAF just forward which in turn spins up the Nr. During normal flight the induced flow is less and the Taf is just behind or else the rotor would spool up on you during normal flight. Same thing happens in uncompensated cyclic turns. The change in the induced flow will spool up the rotor that's why you have to apply collective in rapid turns, it's not only coriolis you contend with in rapid lateral cyclic inputs.

If it were a single rotor a/c with a counterclockwise blade rotation, that would have been a perfect candidate for retreating blade stall, but I truly don't know if that's even a factor with the coax rotors, it's actually something I've been wondering about for a while. Does a BS experience retreating blade stall at high speeds? Just curious.

There are three regions in a helicopter blade. The Driven region near the tip, the Driving region near the middle and the Stall region near the mast. The Driving region has a Total Aerodynamic Force vector that is inclined slightly forward of the axis of rotation and produces a continual acceleration force. This direction of thrush provides thrust which tends to accelerate the rotation of the blade. I know this explanation would be a lot better with a picture, but the even a symmetrical blade will have three distinct regions that will act in different ways during a power off condition. Let me know if you need more detail. Bottomline a fan blade is not a good example of a rotor blade.

YOU DON'T! Attack

Yeah winds are huge for helicopters especially when it comes to gunnery. Definitely never pull the trigger until you are in a stable platform, especially hovering. When you fire while inducing movement you get into the aerial ballistic of angular rate error. This obviously does not apply to guided munitions.

I'll take you up on that, should I do it straight to the Wiki? To be honest I've never messed with wiki, but I'll figure it out.

Good stuff Ruprecht, I was surprised there wasn't much in the way of an aerodynamics section in the manual for BS. No mention of retreating blade stall, transverse flow, ETL, dynamic rollover, blade coning, performance planning, etc. I mean they mention the hover power check but don't really explain the purpose behind it, to weigh your airframe and check how much power available. But that's where the online community comes in which makes the whole experience a lot more enjoyable. I haven't flown the sim yet but I'm having a blast just talking aviation in this forum.

They're called pitch change links or PC links for short. They are a ball and socket type hinge. It's a very ingenious design.

Three things necessary for the vortex ring state or as we call it in the US Army settling with power: Low airspeed, vertical descent beyond 300 ft per min, and 20 to 100% power applied. Easiest way to get out of it is to apply cyclic in any direction to "fly out of the vortices". The worst thing you can do is grab an armpit full of collective it will only make matters worse with one exception, if you have pwr available you can power out of it with collective however best thing is to outfly your vortices. Also if you have altitude you can get out of it by decreasing collective but your descent rate will be very high. As far as your heading problems, check where the winds are coming from because even with heading hold modes helicopters will weathervane into the wind. If you're not tracking a course to your waypoint ie have a crab angle that counteracts the wind so you fly directly to your next waypoint even though you may be in trim the wind will push you off your course thus deflecting your waypoint caret. Just some thoughts, and Ruprecht's exercise is a classic helicopter control touch exercise very good way to get your feel for the antitorque.

Very cool AlphaOneSix, I'd definitely be interested in linking up with your squad if you'll have one more. Like I said my time will be at a premium but it would be cool to get into this sim around some Army guys. Let me know your squad info, you can PM if you don't want to broadcast it.

Yeah, as an American Helicopter pilot I used the word torque to mean how much twist force on the engine driveshaft, I know some other countries use other readings to measure pwr available, but Torque is definitely a very useful way to gauge power output. Since I haven't really jumped into Black Shark I don't know how this sim does it, I was just spitballing on the scenario with just my real world knowledge of american rotorcraft. You should say that the helicopter wants the RPM to remain the same which may or may not be what you need. Trust me if you grab an armpit full of collective and ask for power you don't have or like in this scenario you're already asking for around 97% and you lose a bunch of bleed air which would otherwise be cooling the engines, you'll be asking for power beyond what that steady state RPM will let those engines give you. In the first scenario you'll droop the rotor bc even at a 100% pwr the engines won't be able to push the pitch angle you're asking for through the air and in the second scenario you will loose the ability to cool the engine so your nominal 100% pwr will be reduced. Most engines these days won't let themselves get cooked so it'll hit some temp limiter range and just bleed off on you, it doesn't care if you're 100ft AGL on the side of a mountain. Anyway, maybe next time ask for clarification about what someone else means before you dismiss them entirely.

Is that Engine anti-Ice running off bleed air? Usually with Eng Anti Ice on you lose about 10-20% power available so if you were at 97% torque and you kicked it on you would get into temp limiting and the engines would bleed off IOT prevent burnout. Also be aware that at very low temperatures you can get into fuel flow limiting even though your eng temp might be low. I guess the gearboxes got hot bc oil got too thick? I haven't delved into Black Shark yet, I'm just amazed at the level of detail you guys discussed from a CW ops POV. I'm impressed by the fidelity of this sim so far. Attack!

I'm a Warrant Officer just out of the Longbow course, but I've been into sims most of my life. I used to be in a Full Immersion IL2 squad. With the arrival of Black Shark I'd be very interested in joining a serious squad preferably one with other Army Aviators. Attack pilots would be best, but girlhawk pilots may apply lol. It's just my luck though that I'll be busy with an OIF rotation in the very near future so I won't really have the time to stand up a new online squad. Since beggars can't be choosers, I'd be interested in flying with any serious squad out there that already has a solid structure to progress newcomers etc.
