Vortex ring state question

[Daniel M]

 

Sink rate should be written "-3m/s". Anything "below" this number means higher sink rate.

Sorry, my typo. Above is what i meant.

This is probably frowned upon, but if I need to descend in a hurry I quickly snap roll the helo onto it's side until the rotor disks are vertical so that it loses all lift and knifes down quickly. To arrest the descent I add 3/4 collective for a second before snap rolling the helo upright again. This imparts a fair bit of sideways movement which helps you avoid a ring vortex state when you come back horizontal to stop the very rapid decent. It's very quick and violent and takes a bit of practice to get it right without pooing yourself.

That sounds like a good technique to practice, Zomba. I'm going to the Shooting Range tonight to try. By the way, I know Vortex Rings are supposed to be bad but I just love that this sim is so deep that these things can actually happen. ;)

Too bad for the trees. Hopefully they will implement this in a future patch.

Does staying at very low altitude help in any way against being spotted/locked?

 

YES!

 

Below 10 meters if the HAWKS or SAM-11 are active

 

The 74th Fighting Tygers server has a "Dynamo 1st phase" mission to experiment this technique.

 

In this mission it is nice to be able to fly through the trees. I use rockets and the sighting pipper to kill the power plant, WP1.

 

But then Tyger spiced it up and put manpad pits on the way in.

 

My collective is set on my Pro Throttle and I fine tune it and and curves to it to be very sensitive.

 

As to the vortex-ring state? You can recover if you have the altitude. Learn how to fly using the Flight Director. Transitioning to hover from high speed is what usually gets me.

 

I like to hover just a tad above a ridge. This way the SAMs don't "see" me and I can take them out with Vikhrs.

 

I tell you what, helicopter rotor blades and chimneys do not like each other as buildings being soft.

I do that, too, especially rolling it like a barrel-roll.

 

Look into using the "Free Turbine RPM to Low" and set a button for it while rapidly moving the collective downwards. I drop like a rock. Then at about 150 meters I engage "Free Turbine RPM Nominal and up collective and watch the Up/Down gage. I am moving forward, though, usually rather rapidly.

That sounds like a great maneuver! There's nothing to frown upon. Best pilots learn to get everything out of their machine to gain the edge over the enemy. I'll start experimenting as soon as I get my Komodosim pedals. :)

They say to get out of a vortex ring, you have to pitch forward to get out of it. But it doesn't absolutely have to be forward, right? You just have to move out of it regardless of the direction?

 

 

With a "normal" Helo, the super ultra best thing is fwd and right or left, (depends of the Turning direction of the Rotor)

 

With a Koax, where you have one "Airstream" in the one direction, and the other in the otherone its fwd.

Also, it's good to make a habit of glancing at the variometer regularly, especially when hovering. I keep looking at it constantly, keeping in mind the 3 m/s mark. The variometer is your most important instrument.

Hiding behind a building can be compared as "taking hostages".... Well - it's a videos game, dead civilians will respawn at next game crash. :P

 

Lol ;-) Luckily not so many crashes anymore though - would love to see some bug-squashing in the KA-50 module though :-)
