from the book "chickhawk"

[wess24m]

So in the book he describes the Huey, with its large weighted blades, being able to pick up and hover for three feet then make a 180 degree turn before the blade runs out of energy. I've tried this many times, with the most favorable conditions (5% fuel, completely empty) no wind and can't even begin too replicate it.

 

I get the blades and turbine up to operational speed and cut the fuel while adding collective. I've even tried going to manual governor (forcing max rpm) and doing the same and can't get even to 3 feet off the ground let alone pivot 180 degrees.

 

Anybody have any info if what he said in the book is accurate? Also when he was learning to auto rotate he said that you bottom the collective and we know the rest but when you bottom the collective you loose all control of pitch and roll. Any input would be helpful for us and the team I'm sure.

I think its still early days and I am sure Belsimtek still have some tweaking to do :)

 

Great book chickenhawk :)

"Chickenhawk" is even mentioned as reference in the Huey manual. So hopefully Belsimtek take the author as a valid source.

Loving it so far.

Yup

:thumbup:

Just a thought. If you read the operations manual of the UH-1H it also has two types of blades. the Metal blades and the composite blades. If i am not mistaken some from the developers/testors stated that this aircraft is modeled with it having composet blades on the Huey. This i am sure also would be taken into effect as the blades are also not as heavy

That would make sense, but seeing as everything else is Vietnam model spec, I wouldn't think they'd chose composite over metal. Whichever it is still a great Sim.

[Sundowner.pl]

"Everything else" is 1980's model spec ;) Composite main rotor blades are 1985+ so its fine. Especially as those CMRBs are not affecting much of the flight characteristics - looking at the brochure - 6% better hover performance, and 5% reduction of fuel flow.

 

Now, the question of their inertia (weight) - I don't have data for those main rotor blades, but the newest, carbon blades are 20% lighter than the original metal ones. Are the 1980s CMRBs as light ? I doubt it. Will have to look for some info on that.

Great book that the one pargraph from that book which sticks in my mind is the draining off of the condensation from the fuel tanks which had accumilated over night which some rookies forgot to do oops.

Bingo.

 

There is more inertia in the metal blades. They will spin up slower but will hold RPM better.

 

The composite blades are better fuel economy in flight. Composite was used for the model.

Thanks for the answer, I should have checked the manual, it says right in there duh.

Just re-reading Chickenhawk for some flavour while I learn to fly the UH-1. Very vivd... Makes me want a South East Asia terrain and Fortunate Son on the stereo.

Regarding the rotorblades of the "D" and "H" Huey, the CB from the 80s/90s had nearly the same mass as the MB. Maybe the center of gravity varies, but it shoudn´t vary too much as well. Don´t know if there are newer CBs.

 

In his book Mason wrote "...normal rotor speed (330 rpm) he cut the power...four-foot hover, turned completely around..."

The "H" Huey has not a normal rotor speed of 330 rpm, so maybe it was a "A","B" or "C" Huey he was talking about.

 

In DCS I managed 180 degress but only when performing everything simultaneously.

Well, isn't 180 degrees the meaning of "turned around"? Might be my lack of understanding the english language here (non-native speaker), but if I turn around, I am facing the opposite direction, no? :o)

[TurboHog]

Composite rotor blades may be 20% lighter but how does that possibly account for this huge difference (3ft hop vs hover and turn)?

 

I don't believe this 3ft hop is what is supposed to happen.

Flagrum, you're absolutely right. Somehow the "complete" gave me the image of a 360 degree turn.

 

Turbohog, i think it's more artistic freedom in Mason's four feet "hover".

Again, the mass difference between the original metal blades and the 80s/90s composite blades is less than 1%.
