While on the subject of Helis in movies.....(and before anyone says anything yes I was bored) Whoever was flying the Huey in Rambo 2 did a awesome job. He really threw it around, and then some!

Surely a C-130 is a bit tight for a 500 to be running in ?

Well a 500 has a 26ft 4in (8m) blade diameter, so in order to have some room for breathing, C130 would probably need to be 9-10m wide in the load area, which considering its cargo area is only 12m long, seems a bit unfeasible! hehe

good point mountjoy.

and wouldn't the door/ramp/opening be even narrower???

"mylesdw" Is that the startup checklist or the "in the event sudden removal from a transport aircraft" checklist lol

well yes, i would say so seeing as the aircraft has to be somewhat aerodynamic! i think total loadable width is 3.12m in a C-130

it is a james bond film though, i dont think the average viewer looks that deeply into these things.

C130 departure

As has been noted ... it was a JB epic and little things like the facts have never got in the way of a good shot.

Seem to recall my firm's involvement in Goldeneye, when our pilot was called on to land our black Robbo on a moving Ruskie train. Not sure where the producer thought the blades would go as the hydraulic clam shell doors closed (a three day sequence finished on the cutting room floor.)

Returning to the C130 500 exit, nothing there that sawn off M/R blades, an electirc motor and a well judged cut couldn't have coped with. (you should know these film boys) But as a bar discussion, who wants to speculate how the real heli would react for the requested sequence, when reality took over!

Must have had a quiet day!

Chaos.
to many variables.
What blades broke. if not all.
Where did they break along their length if not at Root
how dose each broken blade interfeir as it is Falling.

Re VRS. in previous Asumption. Not going to happen, till power on.

Any one care to Speculate on
Given some mad Military Dudes Straped you in and pushed you out. What would you Do besides Scream. IE.
what would your controle inputs be. (Hydrolics not working ?)
You are locked in the seat so Jumping out is not an option yet, (Ever ?) Hmmm If I did jump out Id leave it till i was 20ft, I would probably survive a 20ft fall .


This brings thoughts of problems involved when thinking of how to stop blades in flight to get a faster stub wing lifting like in the X wing. just in reverse.

Heres a question for you then...

on helicopters like the apache, the baldes are strengthened enough to allow them to roll unside down without them strikeing the tale.

If strengthened enough for that would they be able withstand a freefall from a plane (as in film) without bending up and snapping?

MD 500 exit from a/c

..... just to recall, the blades are turning at 500 rpm. If 150 knots TAS doesn't flap the blades to breaking point, what changes ? Maybe a scream or two !

The starting windspeed limits for many helicopters is about 45 kts maximum. Any more than this and the blades may well make contact with the airframe. This is on level ground, with the airflow coming from one direction, normally from ahead.

How fast is the airspeed of a plummeting and tumbling helicopter, falling from the rear of another aircraft travelling at about 150 kts or more, which is likely to be over the Vne of the helicopter with the blades under control at flying speed??

Totally ridiculous idea.

Aaaaand here we go again!!

"1 sec. to death on the R-22 myth!"

I can demo you at least 3 sec. WITHOUT moving the collective at all..
Just have to flare progressively....
1 sec is the time if you want to maintain speed and altitude.
3top
There was a thread sometime with a R-22-turbine.
However it was a homebuilt-project, that was to use a R-22 cabin section, nothing else...
I saw a couple of times a rotor NOT stop with the right angle and amount of wind, but never start spinning by itself....
James Bond is fun, but at least they should keep it remotely possible.
The Porter, the Turbine-R22, the BD-5.
But 350-backyard, MD-freefall-start, etc, get out of here!!
I asure you we are not the only ones to complain about Holywood:
Discussing this very subject with a client he said his wife was all upset with
"The Gladiator" ???
She is a Historian and Archeologist - some of the costumes were over 300 years wrong!! Imagine yourself running around in 1700 outfits...
So, Aviation is not the only area for mistakes "only professionals would see" !!

JB stuff

Please ..... the 500 heli blades are already running and planned exit speed 110 knots ! No lost sleep, we weren't thinking of giving it a go!

DRK:

Although it would be an absolutly barking thing to try....
I can't say how the blade would react at 150kts, but I've started a helicopter in the 'relative' lee of a hangar, then lifted above the hangar into an 80 kt wind. Sporty, but it definatly was not as sporty as I was expecting it to be.... As I say, not sure about 150kt but 100-120 may just be possible. Just anticipate with cyclic and get everybody else to hold on!!!!

Regards,

NV

I hope to heck it gets pushed out backwards and running from an antonov.
If it went forwards , regardless of the ability of the main rotor to withstand the sudden loading, what happens to the tail boom & rotor.

I bet the tail rotor strike would be intersting & the loss of tail rotor from ( lets be nice and say 15,000ft would be awesome.

Then you would want to shut down , wait for the main rotors to stop spinning to snap off so that you can exit the aircraft in a controlled orderly fashion & pull the rip cord to the parchute you knew you were going to need when you signed up for this crazy job.

LOL

500 departure from moving aircraft

That's good news ... at least someone thinks it could happen. Yes a rearward shove was the plan and now we know 80 knots is possible.

And of course the Antanov or silmilar would be towing a ton of turbulent air so the acceleration zero speed to 120 knots wouldn't be instananeous.

Methinks a rapid cyclic response might do it!

Can't we move on to something less idiotic .. . or any more views.

Talking of helicopters in films, has anyone seen the Guardian yet? From what i saw, very sensible, no stupid editing of the sea hawk!

I liked it though the multiple endings sucked.

I also thougt they didnt talk about the pilots or the helos as much as they should have , it was a great PJ movie but I like the helicopters more in a story.

good flick though

Concur all about that movie. It was a bit to long with those two in it, probably due to all the filler sections in it. How many times do we want to see someone doing laps of a pool, even if it’s in fast forward! The love interest, why did we have to have that?! Couldn’t it be just like real life where he finishes, cleans up, walks out and says thanks on the way out the door.
