Nage Posted January 2, 2014 Posted January 2, 2014 Well i`m puzzled. Although i can fly BS achieving top speed by using collective i`m wondering what is throttle used for then? From what i experienced it increases RPM and by having throttle at 100% or all the way down is same thing, just seems better to have throttle set on medium or as i tested all the way down in Hover mode. Am i doing this right? Is there any proper usage of the throttle in different stages of flight? Does it need to be set at all? p.s. a lot of questions i know :D
Brutov Posted January 2, 2014 Posted January 2, 2014 Use the Throttle not as Flight-Control. Start the Engines, Driving up and Fligh with one Setting.

Nage Posted January 2, 2014 Author Posted January 2, 2014 Yes i was flying with the collective but then i wondered what is the proper usage of the collective with throttle because the throttle can be both at 0 and 100% with quite same effects.
Balion Posted January 2, 2014 Posted January 2, 2014 Yes i was flying with the collective but then i wondered what is the proper usage of the collective with throttle because the throttle can be both at 0 and 100% with quite same effects. The proper usage is designated in flight manual: The throttle levers have four fixed positions: 1. Idle. 2. Governor fail. 3. Auto. 4. Max. At IDLE mode are usualy performed startup procedures and most of the systems functional tests. GOVERNOR FAIL is needed in case of failure of power turbine’s RPM governor to avoid engine (power turbine) overspeed. AUTO is the main mode during normal opertion of the powerplant. All flights must be performed at this mode, except for specific emergencies. MAX mode is intended to ensure maximum power of one engine in case of failure of the other engine.
Nage Posted January 2, 2014 Author Posted January 2, 2014 Balion, zhank you very much for explanation sir. Makes sense now.
Bushmanni Posted January 2, 2014 Posted January 2, 2014 The strange thing is that even if your throttle is not at auto position, the governor is still in control somehow. As OP stated, you can fly with throttle at idle and rotor RPM stays in the proper range for flying. If you raise collective when idling on the ground the RPM will suddenly rise to flying RPM. I haven't tested this actually with the latest version but this is how it was when BS2 moved to DCS World and apparently still is.

Dr. Yes Posted January 3, 2014 Posted January 3, 2014 Its also used to fly high in thin air, like going over mountains. If I remember correctly, with governors off, and full throttle (max), the engines can survive for about 30 minutes before burning out? There was some thread about this somewhere. But even if you make it back to base, the engines are going to have to be overhauled because of the strain.

I haven't tested this actually with the latest version but this is how it was when BS2 moved to DCS World and apparently still is. the "govenor fail" position probably works by slaving the throttle to the collective. This is how we do it with model helicopters, the collective stick controls the collective AND throttle servos simultaneously. To prevent overspeed, the pilot must establish precisely correlated throttle and collective settings for a given stick position and program them into the radio. In this way, the engine is always providing the correct power for the load on the rotors. With RC models, this mixing is achieved electronically in the radio. In the Shark, i would imagine it is mechanical.
