Quote from: Freightdog862 on October 25, 2023, 06:16:14 AMI did look at Rotodyne stuff with Paul Lucas a while back, sadly what flew wasn't much like what was projected so we didn't proceed, never say never though..   

New, longer wings maybe? 

Fuselage extension plugs and alternative decals.

Re. The Rotodyne.  IIRC (the relevant book is in storage) they had progressed some way with lower noise rotor tip nozzles before the whole thing was cancelled when Westland took over.  I think there are pictures of the designs.
A set of them would be nice but I'm not sure you'd sell many.

There's a whole slew of 'quieter' 'dyne tip jets at the Helicopter Museum at Weston-super-Mare, maybe 4-5 different types, along with some rotor blades, the hub and a chunk of the fuselage as well. Visually there's not that much difference between the quieter jets than the originals, they're a bit fatter, and have more ventilation holes, but that's about it.

I'm sure i've seen some with four square outlets.  Maybe I am imagining it.  I need to do research.

Kit - I know the feeling

If all my pics weren't filed away on an archive drive that just REFUSES to connect to my laptop      I might be able to post some pics of the tip jets at Weston. Maybe soon though.

There are pics on line.  They are as you describe.  But I am still convinced I have seen other pics.

The 'dyne book says they tested LOADS of tip jets to make them less noisy, so I could well believe you're right.

Would this be similar to a Hush-Kit?

I can only find three types in "Fairey Rotodyne" by David Gibbing, the original tip burner , Type 8c which was used for most of the time the aircraft flew. THe 8c had a seven lobed attachment, looks like seven fruit segments, points to the centre and symetrically rounded ends to the outside,. There was another picture that showed what looks a bit like a high bypass fan cowling which was mounted towards but not at the rear of each tip. This had multiple fluted intakes to the front and blunt exhausts with a faired cone to the end of the tip jet so I can only assume that the exhaust from the tip jet was mixed with air passing the tip jet in an attempt to reduce the volume of the tip jet's output.
Not saying there was never any square tip jet exhausts, just no pictures in the book I have.

What would of happened if the jetpods were removed from the rotor blades, would the blades have created enough lift on their own?

Anything can create lift if it is at the right angle and has enough force behind it, even a brick!

Nothing, the aircraft would stop flying! 

The tip jets make the rotor turn on a Rotodyne, there's no shaft connecting the hub to the engines.

Yes but surely it would just become a bloody big autogyro?  Didn't the tip jets augment the autorotation  resulting from the forward motion generated by the two Elands?

Granted, VTOL performance would be non-existent.

If you remove the stack as I have on many builds using the Airfix or Revell kit, the build could make the basis for a STOL aircraft or helicopter if the wings are removed.
