UH-1H throttle management?

[Diplocaulus]

I've got a noob flight control question.

 

QUESTION: How important is throttle control to flying the UH-1H Huey? Is this something I will be using a lot, and should I map the throttle control to my joystick?

 

As a PC flight simmer, the helicopters I've flown in the past required just collective and cyclic control, and I always assumed throttle (RPM?) for helicopters was constant for most flying. Now I'm reading the manual for DCS World's UH-1H Huey and it's talking about throttle control as well. Is throttle management important to flying this sim? Or does one setting work well for most flying (with of course the exception being startup/shutdown).

 

My control system is pretty basic: a single Thrustmaster T-16000M Flight Stick.

 

Thanks.

The rotor RPM in the Huey is automatically regulated by a governor. In normal flight your throttle will always be fully open, and you don't need to touch it. I typically touch the throttle only upon start-up of the helicopter. So, in short, the throttle is not very important during normal flight. Hope that helps.

That helps a lot. Thanks!

Hey,

 

watch the autopilot when in Level flight, it does reduce the throttle a LITTLE bit in most conditions

but I personally nevr touch it when flying myself.

 

When we fly our R/C Hekicopters we very well do adjust rotor RPM for specific reasons, but it has to be said that most R/C helicopters have far far more power and can safely fly in various RPM configurations.

 

The higher the RPM the more responsive your collective and cyclic is, the better and more skilled you have to be to show off a smooth style. You have to take caution not to over-pitch on collective as with the same blade angle you pull/push far more as when on the lower site of of the RPM band.

 

The lower your RPM the smoother you can fly the chopper and the more forgiving the it is.

You just have to remember that your maximum responsiveness is limited and you have to fly with

more pre-sight of what you want to do with it.

 

If I was to fly a cargo chopper I would choose lower RPM and higher angle of attack to not oversteer the AC. The more aggressive I want to go the more RPM I would dial in.

All with in it's limits. A certain RPM is necessary to maintain a safe flying attitude for a given take-off weight.

 

The range, for example, goes from 1.200/1.400 RPM to 2.000 RPM on a 1.5m rotor Heli afair.

The higher quality your helicopter is the higher the RPM it can take.

1.200 would be beginners level, easy to control and forgiving

2.000 is 3D style with high responsiveness and thrilling capabilities.

 

I don't think full scale Helicopters have a range that big, but 10% should be possible.

 

The higher you want to fly the higher your RPM must be I guess in RL.

Climbing to 7.000m in The Himalayas for Rescue Missions for sure needs full RPM, full throttle and ground effect or you won't make it.

Green RPM range is 6,400 to 6,800, so even less than 10%.

 

The upper RPM range is due to structural reasons (more force on the blades the faster they spin); the lower range is to prevent excessive coning angles (the angle the blades bend upwards) as this reduces disc area and therefore lift.

 

High rotor RPM gives more lift which is good for flying high, but as you climb engine power reduces to the point where it can't overcome rotor drag and can no longer maintain rotor RPM.

 

Hope that helps.
