That was a great explanation, very will said...thank you. As a private owner/pilot of a R22 Alpha, I can also add that hovering over water can cause the same problem and the helicopter will sink into the water. Add some cyclic in any direction to move the helicopter before it is to late. Unless you have floats.

great info .. I am / was a super experienced R/C helicopter pilot .. after a demo flight the approach was compromised by the tailwind with high buildings making an into wind approach not an option . my 1.6 m rotor dia Jet ranger model entered a vortex ring decent . Thankfully I had been in David Nieman,s Robinson R44 when he showed me an autorotation and a vortex ring recovery .. his method which worked for me with my R/C model .Was to dump the collective and get rid of the dirty air . I loved the lama smoke effects .

You are explaining very well why most pilots react in the first monent in the wrong way raising the collective pitch when they feel a sudden loss of altitude. Good to know how to avoid a Vortex Ring State situations with avoiding too few airpeed, too how decending rates and tailwind. And it was amazing to see how fast you can end this state with flying out forwards or sideways. I am just flying RC helis, and they have so much power in relation to the weight that we don't experience such problems. But even though I am avoiding tail wind landings and take offs because I feel much less control.

Thanks for the nice explanation. Today I flew my mini drone. Battery was slowly getting low as I was high, directly above me so I put it into sports mode and pulled the left (throttle) stick totally down. It descended a bit shaky but well and quickly. I was surprised that I was totally unable to recover the descent although timely trying to add thrust. I crashed but thankfully into the grass and nothing broke. My first thoughts were about software (feedback and control), battery having less power/voltage, hot esc's (speed/motor controller) and stuff like that. But maybe it just was some kind of vortex ring state. Guess I will compare to what happens when i apply forward speed in one of my next flights.

I have asked on other channels explaining VRS before, but never got an answer. How does VRS act in a coaxial rotor design ? Since each rotor is rotating in the opposite direction, would the vortexes cancel each other out, making VRS impossible in a coaxial rotor design ?

@flyhighytbwithcarolapilote 8 ай бұрын

That’s a very good question. I would imagine that VRS is still possible in a coaxial rotor design because there is still a downwash and VRS happens when the rotors get caught up in this turbulent downwash.

What are the real chances of recovery from a vortex ring state❓

@flyhighytbwithcarolapilote Жыл бұрын

If you have been well trained and you are high enough you have an excellent chance to recover bit it all depends on the circumstances. However the best is to remember the golden rule and never get into the vortex ring state in the first place.

@OOTurok Ай бұрын

Using the Vuichard Maneuver, you can recover within 20-50 ft altitude.

How come every time when hovering you don’t go into VRS?

@flyhighytbwithcarolapilote 11 ай бұрын

In a hover, you have the advantage of ground effect and you are not descending into your turbulence.

@greysheeum Жыл бұрын

One note: The Vuichard method should ONLY be used BEFORE entering VRS. If you increase power after developing VRS, you will accelerate downward dramatically. It’s possible to reach rates of descent over 6000’fpm within a couple of seconds. I have not seen a video that actually shows a fully developed VRS from in the cockpit on any of these teaching channels and it’s unlikely that any will ever surface since most instructors have never experienced fully developed VRS themselves. If you ever truly experience VRS and attempt to raise the collective first to get out of it, you will vow to never attempt that action ever again.

I can demonstrate with a R66, that I will recover by just raising the collective only. Weight and DALT are factors too. Some Situation you don't have time to lower the collective first, you pull and at the same time you give the cyclic the impulse where you have space. If doing Vuichard know which side to recover is very very important. But always do as you were taught at school and never try something else without a instructor.

@flyhighytbwithcarolapilote 9 ай бұрын

Wise words 👍

@OOTurok Ай бұрын

This is false... because with the Vuichard Maneuver you do NOT raise collective "first". You raise collective, while simultaneously appling cyclic & opposite pedal. The sideslip from apllying cyclic & opposite pedal... immediately moves the rotor tips outside the turbulence where they can generate lift, & the increase in power literally pulls the helicopter out of the vortex. This is why the recovery is so fast. If you are pulling collective "first", before applying cyclic & pedal... you are performing the maneuver WRONG.

@greysheeum Ай бұрын

@@GyrocopterGirl You describe pre-VRS conditions. If you ever actually entered into VRS, you would know to never raise the collective to attempt recovery. Only increase power after departing the dirty air column or at low levels of descent.
