berkoutskaia Posted April 13, 2005 Posted April 13, 2005 Hi all !!! I'm part of the manual translation team on C6 (french-speaking forum for virtual pilots), and I am unable to understand the meaning of a few sentences in the english manual. I do understand the words and all, but I don't understand the meaning. I thought maybe some of you could help... I just need to know what the manual is talking about in those sentences: Angle of glide availability is determined by the pilot’s efforts and the plane’s position. (page 208) Well, as far as I know, the "glide" is the ILS sub-system used for proper descent plane. I understand that the glide radio signal is only available if the plane is located in the radio beam, but what have "the pilot's efforts" got to do with that ??? I'm sure I got something wrong here :( Low RPM over-speeding is modeled.(page 209) Well, I'm no jet engine specialist, and I don't understand what physical phenomenum lies behind this. If someone could explain, I'll really appreciate ! adjustable stabilizer surfaces(page 209) Is it elevator or rudder trim surfaces ??? Or am I getting this wrong? Thanks for your help, I'd better wait a little more than having those sentences translated in an ugly way! In Mud I Trust.
169th_Cobra Posted April 13, 2005 Posted April 13, 2005 Angle of glide availability is determined by the pilot’s efforts and the plane’s position. This doesn't make sense to me either. It seems to be a bad translation from russian to english. Perhaps someone who can translate the original russian manual could give a better translation. Low RPM over-speeding is modeled. How you overspeed from low rpm is beyond me. My guess is they meant either High RPM over-speed or Low RPM under-speed? Again a russian translator would be required to sort this one out also. adjustable stabilizer surfaces most of the fighters use a stabilzer type tail plane where the entire surface moves. (jump in game and from an external view watch the whole tail plane pivot as you put in pitch inputs.) to trim it you just move its "centered position" slightly either way, as opposed to a traditional tail-plane is fixed with movable elevators at the rear of it using trim tabs. i hope that makes sense and if it doesnt i'll find a picture of what i mean. :)
berkoutskaia Posted April 13, 2005 Author Posted April 13, 2005 Thanks for your help about the stabilizer surfaces. It would mean horizontal tail plane then, I suppose. And I totally agree that some sentences looks like a raw translation from russian to english, si if an russian speaking forum member could help... In Mud I Trust.
ZoomBoy27 Posted April 13, 2005 Posted April 13, 2005 Hi all !!! (page 209) Low RPM over-speeding is modeled. I'd been reading on a web-site for Propellers (under Windmilling and Over-speeding) and they talked about the wind-forces that occur. At low RPMs and in a dive to the ground, there's a lot of force on the propeller(fan in this case). Because of the forces and the high velocity, the fans would spin faster(lesser loading)and then over-rev(have too many RPM(Revolutions per minute)). To quote from the web-site: Remember that as the aircraft airspeed increases, the AoA decreases. This means that as the airplane speeds up, there is increasingly less drag on the prop, and the engine is unloaded and wants to run like wild. Now to translate it: You could just translate it as is and let the user find out for himself or try to provide a full description. Looking forward to it as I'm bilingual but have a poor plane vocabulary. New words tolearn mmmm....

berkoutskaia Posted April 13, 2005 Author Posted April 13, 2005 Thanks zoomboy27 !!! It really seems to be what I was looking for !!! In Mud I Trust.
britgliderpilot Posted April 13, 2005 Posted April 13, 2005 It occurs to me that "Angle of glide availability" could actually refer to glide angle in an unpowered case . . . . . could be something new with the AFM. I'm sorry to say that I haven't spent great amounts of time closely examining the gliding physics in Lomac - either I can get to a runway or road, or I eject :P http://img.photobucket.com/albums/v121/britgliderpilot/BS2Britgliderpilot-1.jpg
SwingKid Posted April 13, 2005 Posted April 13, 2005 This section is dedicated to describing the differences between the new advanced flight model (AFM) for Su-25 and Su-25T, and the previous standard flight model (SFM) for other aircraft, from Lock On. Angle of glide availability is determined by the pilot’s efforts and the plane’s position. It should say, "Aircraft slip now occurs not only according to pilot control input (as in SFM), but also as a result of aircraft attitude." That is - Aircraft slip is now modelled in AFM. In SFM, the slip was only possible by pilot command - pressing the rudder. The aircraft will now slip naturally if it is in a bank. Low RPM over-speeding is modeled. I don't know about this one. I think it should say either "sudden over-speeding" or "temporary over-speeding" - I don't think it is related to RPM. adjustable stabilizer surfaces I think this phrase refers to the elevators, not to their trim. The trim is probably not powered by hydraulics. Hope this helps, -Sk
berkoutskaia Posted April 13, 2005 Author Posted April 13, 2005 Thanks !!! It looks like Chapter 10 could be translated by the end of the day, thanks to your infos ! In Mud I Trust.
