Does the sim take into account lift from winglets?


Recommended Posts

its supposed to if you fly the training mission its states it in there? so do you even have the Mi24?

DCS MI24 is great. Only the MI24P is an old COLD WAR helicopter. (Agility is slow) The flight model and the helicopter itself are not performing well. But DCS is a game and shouldn't be compared to a real MI24. Great for an ordinary game

What difference does that make? Not everyone does the training missions. I'm one of them. I'd rather read up on the various Hind systems I don't know about than sit through a training mission which wastes time by including things I already know. I'm sure I'm not the only one. So if you know the answer then great, provide it, but no need to be a nob about it.

Jeez I was just asking. Don’t get you’re pantyhose in a wad.

Does the FM takes into account translational lift (fwd flight) of winglets? I recall in one of many Afgan docu's, MI-24 crews at hot-high locations, took off downhill , in a manner like a conventional aircraft or glider launch.

Really interesting question.  I believe the downhill takeoffs were to increase airflow through the rotor.  I believe the winglets are ineffective at low speed.  Maybe a real pilot can chime in.

I remember someone once saying the wings make the Hind more stable at high speed.  Also, in the BBC documentary posted here last week, they say wings take stress off the rotor at high speed and prolong engine life.  

In the sim, I have had an entire wing shot off.  Didn't feel a change in flight characteristics.  Was it because the FM is WIP?  Or was it because I was flying too slow?  Not sure.

I own only 2 DCS helos, Ka50 and Mi24.  When the Ka overspeeds the rotor blades snap off.  For the Hind, there is sudden shaking.  Reducing the collective to zero makes the aircraft very controllable(and makes my panic go away).  When that happens it feels like the wings are giving 20% lift.  

For fixed-wing aircraft it is said anhedral wings increase roll rate and help slow turning planes turn better.  When I got the Hind turns felt sluggish and uncomfortable.  I started putting rudder into my turns and that just made everything worse.  Now I have learned to sharply roll the Hind and make cyclic only turns.  Perhaps the wings increase roll on the Hind also.

K-50 rotor blades snap off because as speed increase rotor thrust become more and more asymetrii. So blades which are moving at heli's direction, makes higher thrust due to added heli's air speed and blades which are going back to the tail have their air speed reduced by heli's speed. So right hand side blades are bend up and left hand blades get bend down

K-50 has counter rotating rotors so on the right side upper rotor is bend down and bottom rotor is bend up at certain speed they just hit each other 🙂

Translational lift is normally associated with the rotor only. With increasing forward speed from hover to bucket speed, the required power is decreasing, resulting in more lift/speed for the same power setting. The wing serves for off-loading the rotor at higher speeds. I can imagine the winglets are added to the wing as an additional wing segment with appropriate lift/drag characteristics.

On second thought, the Hind's wings are primarily meant to carry the weapons...

Ka-50:

Top blades are retreating to the right side and droop down or level as they have less to zero lift as speed increases.

Bottom blades are advancing on the right and lift strongly as they have maximum lift as speed increases.

 

Both upper and lower blades close the gap between themselves on the right side as velocity increases... it is the weak point on the Kamov.

At maximum velocity you only bank left in the Kamov to evade trouble, banking right is suicide. Even a twitch of indecision to the right is suicide.

 

You can get supreme speed with the Kamov with a little left turn.

With a touch of the pedal you can also pull the top and bottom rotors apart on the right side... at cost... but worth it.... worth every degree of pedal.

 

Most do not understand the Kamov, they are militarized by the book kind of guys.

The KA-50 is a stunning achievement in aerodynamic rotor craft.... Simply Stunning.

 

I am starting to wonder if the chopper Apex was met at the genesis of DCS world.

You know I got to fly her first time since update today.  She felt so much easier to fly than before and I had a wing shot off.  Interestingly I was still able to control her very easily and even land. Idk if winglet loss is modelled in the FM yet because it made me suspicious not I could keep flying but that I could keep flying and engaging the enemy and then land.  Moreso it felt easy - sure a lot is probably FM fixes but idk.  You'd think that having one wing and not the other would have made the helo very unstable.  I landed in a hover.  Well vague hover (drifting alot) but not a running landing.

However I do think the wings are def modelled in the FM Im just not sure if damage to them is or if it's just cosmetic 

I too definitely seem to notice them as I gain speed and I get 'lift'..
