The Avatar Set Up...Can It Really Fly?
Permalink  
 


Ok folks...I'm not much for the Sci-Fi scene...not that there is anything wrong with it...I just get bored if there is no "mechanical" in it. From my perspective, the "movie configuration cannot fly because the rotor chord is not wide enough, as well the span is too short. But, could a modified scorpion fly?....ducted....not ducted? What are your thoughts..............engineers.............please feel free....lol. I did a quick sketch of the one gear drive....................w/o required housing, lubricants, etc. it's not finished. I'll check back later this week-end

Dave

Sorry....I had to shrink the sketch............loses a bit of clarity

I always thought the designs in Avatar were realistic and could fly but I am no expert.

I admit to not knowing the aerodynamic validity of the aircraft portrayed in the film myself, but I can think of someone who does. Next time Sarah is online, she can answer this easily. She works for Boeing as an aerospace engineer.

I'm not an expert either, but a couple of pilot buddies schooled me a bit on rotor span / chord. It could fly if you increase the span and rotor blade chord, but then again NASA has a strange quad tilt rotor that is ducted like the scorpion, but the ducts are deeper. Good input and thanx for the response.

Outrigged.........not sure if this is the german one in WWII or not. Larger span / chord.

The Platt-LePage XR-1... I'd give you a link to Stingray's site for info but he has no page on it! O_O

Sting, its a very well known rotorcraft. Why no page? XD

Well...........I've been up too long.....need rest. I'll do more digging on this one as well some other strange stuff that I've seen. Catch up with all of you this week-end.

Dave

Beware that most of the info in this link is fictious, but they go to quite a length to make it sound plausible.

No worries I'm here! wink

Avatar was one of those movies that made me just sit back and enjoy the ride. So I admit that I did not pay attention to much of the realism and simply dove into the world of Pandora.

But to answer you, I looked at some images of the Scorpion gunship online and it looks real enough, but there is no need to increase the span. The rotor diameter is fine (Nord already flew an aircraft with a similar duct and it was a success).

https://sites.google.com/site/stingrayslistofrotorcraft/nord-aviation-nord-500

A major beef I have is the amount of armament stored on the aircraft, which would normally weigh a ducted-rotor aircraft like this down. I'm specifically referring to the frontal stores... four machine guns?! Why four?!! This would make it too front-heavy and cause it to go nose-down.

Well that's all I can think of right now. I apologize if my answer is short, its a result of my limited time these days. hmm

Sarah,

Thanx for the insight.....................and I forgot about the Bell X22 quad ducted tilt rotor, but I love discussing mechnical problems. Take care.

Dave

There are three rotary wing aircraft types in the movie Avatar:

D'oh! Those other two slipped past me! Regarding the last design, my engineering opinion is simply "terrible". Way too big (and heavy!!!) for quad-config. lift-fans. You can forget about speed and efficiency too. no

I agree. The "C-21" really is the least convincing of the three designs...

Hello!

davh12 and Leela25, I have another picture of the XR-1A from "American Helicopter" magazine, December 1945, page 15.

Thanks, 

Mike

Hello!

Yet another picture of the XR-1A from "American Helicopter" magazine, May 1946, page 8.

Thanks,

Mike

Mike, I don't mean to nitpick, but you should really create a separate topic on the XR-1.

I agree. These don't belong here! Please post the two pictures in the appropriate place, Mike, and we'll delete these here posts for you.
