The venerable Bell 47

[teeteringhead]

anyway the bottom line is that they are all different and you just have to get used to it.

I think that's the key.

When I trained on the RAF Sioux, I guess the squadron had 10-12 aircraft; and they were all different! But you got to know which one did what, so I suppose it was at least good at teaching coordination and Nr awareness!

Bell 47G4

Need to source a few components for this type.

Does anyone have any idea's??

Thanks in advance

Have you tried Trade-a-Plane?

[Ian Corrigible]

Your best bet is probably Bell 47 ASAP or THI. Otherwise, try the recently launched Helinetwork.

I/C

[KENNYR]

Try the Museum of Army Flying, Bristows Helicopters or RAF Wroughton (The last time I was there they were hanging on the walls!!!).

[wg13_dummy]

No chance getting any bits from the Museum of Army Flying. Most of those bits are on XT131!!

[imabell]

what components are you after,

only the motor is different from other models (vo540).

the extra horses to compete against the hiller on spray work,
they absolutely hate overspeeds.

i know where there is one if you are interested.

[breakscrew]

Try Alan Mann Helicopters at Fairoaks, they operate one for training I think. They also used to be Bell agents.

Talking of the Bell 47, I wonder if any of you have ever come across some of the 47's I flew in the States. I suppose the reggies may have changed by now but here goes;

N46DH
N182JR
N975B
N6703D

Love to hear where and when you saw them

Bell 47G-2 diecast models

Pat Gerard,

I live in Australia, and have obtained several very high detail Bell 47G models from a company in Massachusetts USA, over the net.

www.helicoptersonly.com

There is a good catalogue with adequate photographs of your intended purchases for you to look over on the website.

They sell a 47G Police helicopter with a Franklin engine, in blue and white, where you can easily remove the Police placards on the sides, and a Bell 47D with Franklin engine in Mash colours. The interior and exterior detail is stunning.

Lots of other diecast and wooden models of other helicopters, plus a couple of very high quality resin Robbies.

Cheers,

B206B-III

Bell 47G3B1 mod (turbo removed) - hydraulics during engine failure

Have browsed through the flight manual but still require further clarification on this one.

The hydraulic pump on the aircraft IS NOT mounted on the MR transmission assembly.

The hydraulic pump IS mounted on the lower left of the accessory case at the bottom of the engine and is therefore engine driven.

So with this system during autorotative flight (following a total engine failure ie crankshaft motionless) the pump is no longer being driven and all hydraulics are also lost.

Logical to me.

Yes or No?

[NickLappos]

Yep, very flyable, not fun, but not a really big deal.

[imabell]

if you were any more correct it would probably hurt.

B47 hydraulics

Thanks for the clarification. After practice autos at engine idle with hydraulics still operational I suspect in a real engine failure the lack of hydraulics and associated heavy controls may come as a rude surprise for many. A minor yet noteworthy detail.

[Screwed™]

...didn't they move the pump to the trany for the b47g3b1 and subsequent if memory serves me, wasn't it only the g2's had the engine driven pump?

[KENNYR]

If the donkey stops and you lose hydraulics you won't even know the difference..........adrenalin will take over and you will have the strength of 10 men and full underwear !!!!!

[Nigel Osborn]

The pump was moved in the 47G3B2 because of this problem but as already stated, it's amazing how much strength adrenalin provides!

[vortexstate]

Once had one of my students (72 at the time ) have a full hydraulic failure in a B47G5 whilst out in the training area on his own.

He did as he had been taught and returned to the airfield, conducting only gentle left hand turns and maintaining a steady attitude, placing the machine on the ground next to the runway surface. The hydraulic pump had sheared off at the gears in the engine, thus causing the situation, and had to be replaced.

He spoke about his ordeal for months to anyone that would listen, and got a big Bravo Zulu from the CFI on a situation well handled.

Moral; if a elderly student can handle this type of situation in a old B47, then there is hope for the rest of us!

[Lama Bear]

When I trained in the 47G3B-1 we did autos hydraulics off. It is not a big deal.

[Agaricus bisporus]

I had an engine stop during an EOL on my b47 conversion as a 200hr rookie- at maybe 500'. A bit of a surprise to find the controls suddenly heavy but as others said above you just do it, worked fine - greaser! I told the instructor the hydraulics had failed and he said nonsense - we realized the problem in the ensuing silence...

Hardly a bright bit of design, but as the '47 was one of the very first they just hadnt thought about everything then, had they? Thats why people love it, its right back to the pioneering stuff in a 47. You'd be flying a Bleriot or similar to find that level of design experience in a plank...
