Proposal for Producer's Note _ 3- FLIGHT DYNAMICS.wmv

Well , after two amazing videos about ABRIS and Start Up, i propose the third one could be about flight dinamycs. I think its time to see the Ka-50 from the outside , flying, doing some extreme manouvers, and seeing this blade intersection effects, autorotation, ground effect...

I can only second that. Where are the edges of the flight envelope, and how do you avoid reaching them? What happens if you do reach them? I imagine that mast bumping isn't a problem due to the fully articulated rotor design, but here are a few other things that could be interesting to explore:

- Amount of pedal input leading to blade intersection at hover/forward flight.

- Velocity and other conditions attributing to retreating blade stall and blade intersection in forward flight.

- Angle of no return for dynamic rollover.

- How fast-descent-to-hover attributes to recirculation in ground effect.

- Descent rate and other factors contributing to vortex ring state (can it occur during nose-up deceleration).

- Parameters for overpitching.

-

Throw in a few suggested procedures for counteracting systems battle damage (e.g. engine, generator, and fuel pump failures) and I'll be a happy camper.

And don't turn it into a music video. Please.

I would like a FD video too. And it would be interesting to show some autopilot and FCC functions too

Regards!!!

Yeah, some insights into the Rubicon system would be nice, as well as different flight regimes that were mentioned in this thread. Good idea.

Reaching the outside of the envelope in the Ka50 generally results in a loud bang, followed by godawful vibrations and the helicopter beginning to tumble in several axes as a result of the weirdness of two counter-rotating rotor discs with bits missing.

Depending on what altitude you're at, this then either rapidly evolves into a state of being spread all over the beautifully rendered landscape, or your aircraft doing a rather good impression of one of those Olympic divers before closing your eyes, pulling the yellow and black handles, and experiencing another loud bang and a short period of blessed peace and quiet before wondering how on earth you're going to explain the mess. And cursing/praising the length of the ramp start, ABRIS mission planning, low-level ingress, etcetera.

You can avoid the edge of the envelope by not flying too fast, not pulling too many G, not doing anything TOO silly, and not ignoring all those flashing lights and alarms going off in the cockpit.

In fact, you could run a competition after release to see who can bring about the greatest number of flashing lights and alarms in the cockpit . . . . the winner gets a string of Christmas tree lights to attach to their PC in the name of verysillymittitude :P

Battle damage . . . well, so far it's only happened to me in large doses. My strategy is to run away as far as possible and try and flop the smoking, half-functional remains of the helicopter into somewhere halfway flat in such a manner that it doesn't explode on touchdown. And to do all that before it disintegrates.

This is a lot more challenging than reaching for those tempting yellow and black handles, but in certain cases may result in a very satisfying and very marginal landing at a forward base and NOT having to walk home.

Tell me they'll be blue LED Christmas lights, please! ;)

So no single bullet holes causing a ruptured fuel line or a cut power cable? Looking at the fuel system and electrical power diagrams here,

I must admit I was half expecting failures that could be remedied by flipping the right switches.

Does this also mean that you don't have to worry about left/right electrical power systems cross-feed if/when you lose an engine (and thus also a generator)?

Have you ever fallen out of the sky, simply because your descent rate was too high (vortex ring state), or killed engine RPM by pulling the collective too hard?

I think all he's saying is that when he gets damaged, he usually gets shot up too bad for single system failure to be a worry, and that when he does he tries to either make it home or ejects - so no using both fire extinguishers & turning off the engines.

I think the engine allows it, but you've got to consider the minimum level of damage here.

The smallest projectile you're likely to get hit by is .50 BMG or 23mm HE.

Even one of those can do a lot of damage, and they don't tend to arrive one at a time . . . ;)

Perhaps if infantry make it in we'll see surgical system damage.

But don't think you won't notice the superb damage model - yes, a single hit can do a lot of damage, but what gets damaged, the severity of the damage, and the results vary widely.

It almost makes the Su25T look simple.

For mission success I'd recommend avoiding damage entirely, for obvious reasons . . . for discovering all about it I'd suggest spending the first couple of weeks just learning, experimenting, and seeing how many ways you break your helicopter.

Yes. Lots.

Steep learning curve ;)

... Oh yes ..! Oh yes..! I flight dynacs video would be sooo cool.. And If you show the stick/collective/pedal movement in just ONE of the manouvers that would tell a lot about the general characteristics (probably not the right way to spell it.. but my head went blank) it would tell us a lot about how the chopper feels...

Say for instance during take-off, and final approach and a hammerhead turn...?

Flight Dynamics is the perfect subject for the next video. After reading Chickenhawk and learning of such things as the "Huey Tuck" I'm suddenly interested in all kinds of helicopter quirks, particularly those specific to contra-rotating models.

Yes, that would be very nice. And the final move should be a nice autorotation.

Agree, I`m mostly interested in flight dynmics in DCS series! So a producers note on this would be great!

Same here, actually, it would be more fun and less of an fps hit to be able to choose dx 8 rendering, like in FEAR perseus mandate (which sucked, but heck, I had 40 fps). I don't care about Eagles, I care about Dynamics ;)

BUMP!

Yes an FD vid would be awesome!

And yes, Trigger, you spelled it right :thumbup:

According to Kamov, the Ka-50 armor should withstand a Browning round. Perhaps that's *one* Browning round? ;)

I trust the manual will include a few "never exceed" figures, though, so we don't all have to learn the hard way...

Steep learning curve ;)

If it was easy, it wouldn't be very interesting. :)

This makes me wonder if you can eject in first person? I always found switching to 3rd person view during the eject sequence a bit of an immersion killer.

If you wanted to go heavy on the eye candy there could also be a feature where, upon hitting eject, time slows down and the camera pans up to see the rotor blades detach and then pans down to face toward the helicopter before the actual rocket charge ignites...

Or maybe the screen goes entirely black as the pilot either closes their eyes or passes out from the violence of the ejection. Have it slowly fade back in as you're drifting back earthward.

The Ka-50 ejection is not that violent, the G loadings are quite low, not your normal 16-18 (20-22 on others) vertical G loads, something like 6 G for the K-37. Passing out would be unapropriate. The 3rd person view is fine, as long as the ejection sequence is improved from the earlier movies, in which the pilot actually had some kind of air powered Nazi ejection stool. And hopefully we can blow away both side panels, like in the real deal.

Please don't make the mistake (IMHO) EECH made by not allowing to change the view during the ejection, now THAT is an immersion killer.

You can switch views after ejecting.
