Rotorheads Around the World (incl 'Views from the Cockpit')
The pictures appear to me to show a very large clear area. Just curious why they decided to hoist and not just land. Is there something obvious I'm missing.

large clear area
bb in ca:
My guess - eyes can deceive you ..
from the camera angle, it looks to be a clear area, only those on the field would know the obstructions and how level it is to land and pick up.
I got my own question ..
Was the pic of the Sea King an air-to-air pic ?

bb in ca,
I'd already taken the Air Amb in - the 2 paramedics in red are the crew (ie the real workers) of the heli I fly. After 2 attempts to land nearby I'd put our a/c down at the top of a slope about 200m away from, and above, the casualty. On walking back down and assessing the area I considered it too hazardous to reposition the Air Amb (slope, surface and surrounds all sub-optimum), so we confirmed to Amb Control what we'd suggested to them earlier - the task was best suited to the SAR aircraft. That could be the something obvious you were missing, eh?
ecureilx,
You'll see that the pics are taken from a height level with or slightly above the SQ. I was standing (keeping any other walkers clear, if required) at the top of the path, which itself ran up the valley over which the proceedings took place. The high ground to the left (out of shot) is higher than the Queenie, the high ground in her 2 o'clock is also higher; they had a clear escape route into wind in their 12 o'clock.

Excellent pix Thud - I was hiding in the LHS doing 'hoist to crew' for that one and took a couple of you on the ground - I will try and post them as it shows the reverse angle. Who hosted your pix?
bb in ca - the slope is probably 20 to 30 degrees on wet grass, that's why we winched. At least the casualty didn't fall 100 yards further on where there is a 200' cliff!

Crab, I use a Photobucket account - works well for me. When you're back in tomorrow you should find a CD-ROM with all the other .JPGs; if you'd prefer the .RAW files I can get them to you later by DVD. I'm not back in N Devon for a week or 2, but they "know where I live" or you can PM me here.
Last month the Musee de l'Air at Le Bourget opened a new Helicopter display. Magnificent museum, with the most amazing collection of original aircraft dating back a hundred years, yet hardly anyone in the place!
As the 100 Years ofHelicopter gallery had just opened the week that I visited, the displays were incomplete, and there were hardly any boards advising the types on display. So these photos are a bit of guessing game, maybe you lot can label the actual types on display
ps the first two were in the prototype gallery, and are labelled: Breguet GIII and the Ariel II
Djinn?
Djinn?
Hiller 12?
Not a helicopter

Therer are two other shadows behind the pooch, but nothing in evidence to cast them??
The downdraft is hitting the ground quite aways back from the machine signifying a fairly fierce headwind.
I don't this is the case as not only does neither the dog nor the machine with its tail low attitude indicate forward movement, but if there was a headwind then the machine would be canted into it with a partly nose low attitude to remain in the hover for the camera.
Unfortunately there is no evidence of wind effect on the grass behind, which should be the case as it is on an upward slope and would be receiving a small topographical 'jet effect' if in fact the wind was blowing from the front of the picture to the back of it.
Th grass looks like a native of South Africa, 'buffel grass', the colour of the machine, background buildings and the fact that '******' is mentioned, it probably is South Africa.
It's a fake.
so now brown cow, did I win a soda pop?

Those pictures of Musee de l'Air at Le Bourget are a good excuse for me to practice my french!
Why does the helicopter in the 6th photo down have two tail rotors? Was there a problem with longitudinal control?
D3, that Africa trip looks amazing! Work related trip or hol of a lifetime?

Looking at the rotor head there appears to be no provision for cyclic control of the head. Even though the collective would be fully down there should still be space for rotor control but the star seems to be in positive contact.
It is possible, just possible, that they tried using just collective inputs for the head and differential tail rotor control for manoeuvering.
Sikorsky had a similar arrangement with his first experiments though the rotors were to augment, not control, the main rotor.
It would not have been very successful as there would have been too many problems with inflow roll.

Some of the workers don't wear the proper safety equipment (but his climbing boots seem to work well)
Hey we have a trip in 20 minutes. Will it be ready to go by then? (The unsung heroes who keep us in the air - thanks to all the engineers who do great work day in and day out).
Similar experience in Alaska....had a Fox that loved to watch the core drillers at work....he would sit there next to the drill all day long and "supervise". When I landed the helicopter at the drill site....he would look back over his shoulder for a moment and go back to drilling. I guess he found the driller's company more stimulating.
