Forceken Posted March 9, 2023 Share Posted March 9, 2023 Is it possible to freefly the Huey? I've been experimenting with the weight and wind but haven't been very successful. Maybe tether the Huey with a heavy slingload and fly like a kite with heavy wind and no power? Anyone ever attempted this before? Maybe better luck in Gazelle?

admiki Posted March 10, 2023 Share Posted March 10, 2023 (edited) It seems he is asking if you could tether Huey and autorotate it in one place? Edited March 10, 2023 by admiki Link to comment Share on other sites More sharing options...

admiki Posted March 18, 2023 Share Posted March 18, 2023 OK, but what is the point of this? Why don't you just make a mission with Huey in the air and kill the engine? Link to comment Share on other sites More sharing options...

I train students to autorotate with DCS but they have trouble keeping the RRPM in the green so I thought this could be a cool exercise in RRPM control without having to restart the mission or retake off every time they do a full down Edited March 23, 2023 by Forceken Link to comment Share on other sites More sharing options...
SPAS79 Posted April 1, 2023 Share Posted April 1, 2023 You mean fly it like an autogyro but even without a propeller? Just the wind and rotors? Link to comment Share on other sites More sharing options...

SPAS79 Posted April 8, 2023 Share Posted April 8, 2023 (edited) I think you are describing an autorotation. If instead you intended something like soaring (a la sailplane)... IDK if that would be possible at all. This sounds like a stimulating exercise... let's see what I can come up with... So, disregarding and real-world implications such as non-perfect speeds, wind direction variance, friction, turbulence, coanda effects, laminar flow, tanslational lift... In theory, having enough wind coming from below and on the nose (front) of the helicopter... this might be possible. Say you need at least a 2000 fpm wind vertical component to counter the sinking. 2000 fpm should equal to 19-20 knots? Assume 60 knots forward speed as the ideal speed for an autorotation, solving this with pythagorean theorem where the two sides are the two components (vertical and horizontal, dimensioned in knots or nm/h) of the speed, would give an ipotenuse of about 63.2 (miles). So you would need a windspeed of 64 knots, coming right from the front and at a angle of about 19° from the horizontal plane (the ground) or 72° from the vertical (connecting the helicopter CoG to the ground). [see picture] This would keep you hovering, I guess. I have no idea what would happen if you wanted to move forward... My guess is the two components would need to be longer but then IDK how that would work, because if you "elongate" the horizontal component you would need to do the same for the vertical one otherwise you'd start sinking? I have no idea how solid this reasoning is... I would be nice to have it roasted from somebody that actually understands physics and mathematics, something I am completely unaware of. Also, take note that the dynamics of autorotation seem to have been changed in the internal patches and will probably be pushed shortly... so managing the RRPM might become easier / more adherent to real life in the near future. See this newsletter: Check out the new liveries coming to the Mosquito FB VI (digitalcombatsimulator.com) [...] we are now accurately modelling auto-rotation situation readings on the tachometer.

admiki Posted April 8, 2023 Share Posted April 8, 2023 Still not a good idea. It takes up to 60 seconds to reload mission. Place them high and they can have few minutes to practice RRPM control at every run. Link to comment Share on other sites More sharing options...
Xupicor Posted April 16, 2023 Share Posted April 16, 2023 Why do you need to restart the mission, though, couldn't they just reslot and start back up in the air again, immediately? 1 Windows 11 Pro, RTX4090 (24GB), 5950X @ 4.3GHz, 64GB RAM @ 3000MHz, M.2 SSD 8TB, Pimax Crystal Modules and maps: All of 'em.

Forceken Posted May 2, 2023 Author Share Posted May 2, 2023 (edited) I mean the primary reason is curiosity. Autorotating from high up works too. It would just be more fun closer to the ground, and more difficult. Really boring autorotating with nothing to look at for multiple minutes. Imagine soaring in the video below. Makes you wonder what a purpose built helicopter glider would look like. You would just blow thermals to bits haha Edited May 2, 2023 by Forceken Link to comment Share on other sites More sharing options...

I don't watch lul, I got choppers to fly. I give them a 30 minute tutorial and show them ~20 missions I made for them to pick from, one of which is autorotating from super high up. I don't have time to creepily sit behind their shoulder all day. Look, I just want to add something different and challenging to my list for the more experienced sim pilots. If this is such a "distraction" call the FAA and file a complaint. I'm sure they'll LOVE to get back to you. Link to comment Share on other sites More sharing options...
