The HLO is the forerunner of the Gazelle, I think. The SA.340 prototype
still had a conventional tail rotor.

In regards to the proposed attack version of the Puma, if they kept the passenger compartment they would've truly ended up with the Western version of the Mi-24!

Hi,


the first helicopter was X-330,but the second was a mystery,I know that,there was
a design preceded X-300,called X-280,it was a light helicopter,may be it was that
design,and the X-300 became SA-340 Gazelle.

Hmmm, sounds odd but looking at the proposed armed aerial support SA330 derivative looks exactly like the MI-24 Hind which flew around that time?

SLightly digressing to the realms of Hollywood - the Rambo II and III movies whereby the producers used a Petroleum Helicopters Inc. SA330 and modified with ESSS pylons to look like a Hind ......

Cheers

Hi,


from a Germany museum site,may be that was the early drawing to SA-340,note
its T-tail;

Hi all

Sa 340 without "fenestron"
Sa 341 with T tail

I wonder if the swiveling tail rotor of the proposed SA.330 gunship version had anything to do with Sikorsky's Rotoprop as tested on an S-61A (for the projected S-66). The French did cooperate with Sikorsky during the development of the Super Frelon, so to me it's not beyond the realm of possibility.

Sounds plausible. Both have a five bladed tail rotor and french AAFSS uses the main rotor of the Puma.
If the co-operation between the companies was close enough...

Thank you my dear Toura.

In the scope of HLO study, Sud-Aviation has early developped a reduced model of X-300 project, using composite material (almost unknown in the 60s) to demonstrate their capability to manufacture light structure with high resistance.
