amalahama Posted September 13, 2007 Share Posted September 13, 2007 Hi! Ok, now I have a Q for Flight-Dynamics developers (Yo-yo..) In a video of Knight of Skies, a WWI russian simulator in development, you can see how the core computes in real time the value of presure and velocity in each point of 3D space, regards only in the aerodynamics surface of the aircraft. So, you can, for example, "feel" the prop wash of an aircraft in front of you, or the turbulence wake of his wing. My question is: In Black Shark,are the aerodynamics computed only in the heli surface or in all the space, so a Ka-50 next to our can "feel" our aerodynamic presence, in form of vortex rings etc...? Regards!!!!! Link to comment Share on other sites More sharing options...
Bucic Posted September 14, 2007 Share Posted September 14, 2007 Interesting question. As far as I know even atmosphere turbulence is simplified in LO, so I wouldn't expect such a sophisticated model in LO: BS. https://akaagar.github.io/briefing-room-for-dcs/ F-5E simpit project https://forum.dcs.world/topic/318106-f-5e-simpit-cockpit-dimensions-and-flight-controls/ Link to comment Share on other sites More sharing options...

britgliderpilot Posted September 14, 2007 Share Posted September 14, 2007 Check this video. You might find some answers. I'm not sure that answers the question - it shows the atmosphere acting on a stationary helicopter, but not the effects of that helicopter on the atmosphere. AFAIK Lomac and FC treat the atmosphere as uniform for all aircraft - hence no tip vortices or jetwash to fly into. It'd affect ground effect too . . . but then I think that's scripted even for the Su25T. I don't know if it's a change that could be made for Black Shark. Besides, the last thing BS needs is that many more CPU cycles . . . . http://img.photobucket.com/albums/v121/britgliderpilot/BS2Britgliderpilot-1.jpg Link to comment Share on other sites More sharing options...
Bucic Posted September 14, 2007 Share Posted September 14, 2007 I've seen both and it doesn't explain if only specific body airflow is calculated (rotor blade, wing, projectile etc.) or if whole atmosphere dynamics or at least atmosphere in closest proximity of the body is also calculated in real time. https://akaagar.github.io/briefing-room-for-dcs/ F-5E simpit project https://forum.dcs.world/topic/318106-f-5e-simpit-cockpit-dimensions-and-flight-controls/ Link to comment Share on other sites More sharing options...
amalahama Posted September 14, 2007 Author Share Posted September 14, 2007 I think that some atmospheric perturbation model would be very useful for a heli sim, because some effects, like LTE (well, LTE is only applied for tail rotor helo, so maybe in BS is not so important) and Vortex Ring fall (which the heli is introduced in the "prop wash" that himself have generated) are difficult to model properly without these sort of techniques. Some simulators, like X-plane and Condor Soaring simulator has some kind of atmospherics simulation done, and the next title Knight of the Skies is really surprising the effects seen - you can see the smoke to dissolve when the airplane overpass on top.

Shaman Posted September 14, 2007 Share Posted September 14, 2007 There's never been any aerodynamic wake modeled in Lock On. That is why it is so easy to fly close formations behind heavy planes, or even under the helicopter :) When high performing quad-cores will be natively supported by ED's engine, then we can think about asking for that ;) Right now, better don't do it ;) 51PVO Founding member (DEC2007-) 100KIAP Founding member (DEC2018-) :: Shaman aka [100☭] Shamansky tail# 44 or 444 [sIGPIC][/sIGPIC] 100KIAP Regiment Early Warning & Control officer Link to comment Share on other sites More sharing options...
