It starts at around 0:34. The nose dive was done on purpose to exit the turbulent air. You'll find a good explanation for the whole process in the link in the video description (added here for your convenience: www.helisimmer.com/how-to-fly-helicopters/vortex-ring-state-what-is-how-prevent-how-get-out)
Probably because people didn't realize this video is part of a written article and they are not happy that there's no one explaining the process. All the necessary explanation is, of course, in the article, linked in the video description.
wow, that sim scenery during your flight looks eerily like x-plane, not DCS. (dim and brown-ish like) I guess I'm so used to MS2020 now, nothing can compare.
So, you mean that Vortex Ring State is when body is being shaken in random directions (around 0:34), compared to the normal and stable hovering state at the first of the video, did I understand correctly??
Not exactly. Vortex Ring State happens when the helicopter rotor disk gets in its own turbulence, losing lift. Check out the article linked in the video description.
Just out of curiosity: Having played around with helicopters in various sims myself in the past (real life and all that leaves little time for that anymore), I was wondering how DCS (or other sims) let you do the Vuichard Recovery Technique. Just recently learning about this, you see and now I'm looking around for info of all sorts extended to virtual flying like this.
Wow. This is an old comment we missed. Sorry about that. There's no helicopter in DCS right now that allows you to do the Vuichard maneuver properly right now.
Extremely unlikely. This occurs if there is no horizontal motion and you descend too quickly into the dirty air below the blades that's disrupted and creates a vortex in which the helicopter loses control. It would only happen if the helicopter was trying to land straight down and too quickly. So extremely extremely unlikely
Anton Yopp - Your response is not entirely correct! Enabling Conditions The pre-conditions for vortex ring to develop are relatively simple to identify. They will vary slightly from type to type and with changes in operating conditions such as density altitude, wind conditions and all up mass. The 3 pre-conditions are: The aircraft has to be in powered flight. If the engines are not producing power, the aircraft is in autorotation and the upflow of air (rather than engine power) is being used to drive the rotor motion. It is not possible to enter the vortex ring state whilst the helicopter is in autorotation. There has to be a relatively high rate of descent exceeding a true value of approximately 500’/minute. (Note that due to pressure errors at low airspeed and VSI lag, a figure of 300 fpm is commonly given as a maximum Rate of Descent.) Without the rate of descent there is no upflowing air and the reversal of airflow at the blade root does not occur. Likewise, without the descent, the tip vortex is not amplified and so is not a significant factor. The aircraft has to be travelling at a slow forward speed.Due to unreliable ASI indications at low airseed, this isusually taken to be an IAS of less than 30kt. If there is greater forward speed then the vertical flow of air is affected by the forward motion and the vertical components, which are the generating factors, are significantly reduced or even removed as the affected air is left behind the rotor disc.
You know if the gametrix jetseat kw-908 simulates the vibrations experienced in vrs/settling with power (at least with one of the sim shakers addons? Thanks!
does the vortex ring state start at 0:37 when the nose dives?

A greeting for Juarmas one of our greatest heli sim pilots in spain, precisedly in Catalonia.
One question: Why so many haters? (you had my like).
Gran tipo, ese juarmas...

@@HeliSimmer the messenger gets the fury? :P
@@japp3playzz it's called "the internet" I guess?
@@HeliSimmer hehe yep, but its not all darkness out there :p. There is people that can appretiate the work ,effort and skills of others! Cheers mate!
1:07 fancy pro landing, yeah!

Can we see the tail wind emergency thing?

Nice landing. Thumb up
That dive you took at about the :39 mark, I’m wondering if thats what happened to Kobe’s helicopter, imagine being a hill there that is

mrawdog - pushing the nose over is used to increase the aircrafts speed and fly out of the vortex state.

No, stop. Every helicopter video has comments like this from those who don't know better.
It was as simple as vfr into imc
@@pilotavery simply well said
Waowwww perfect landing

Hi there! We do, yes! We have reviewed it in the past: www.helisimmer.com/reviews/gametrix-kw-908-jetseat-turbojet/
HeliSimmer.com awesome! My jetseat is on its way..I’m a real world heli pilot so interested to see how the vibrations compare to real world..
Intro music name please
Sorry, can't remember. It's one of the free ones at the TH-cam music bank.
Are you using VR to look around?
Yes, the video was made by Joe, who uses the Oculus Rift.
Does he have controls like cyclic and collective and pedals?
Yes. He has a Pro Flight Trainer Puma.
