Pin Posted February 14, 2017 Share Posted February 14, 2017 Venerable HS 121 Trident was conceived as DeHavilland 121 and therefore qualifies. This is just an announcement, actual build will start once my 1/144 workbench, that is currently occupied with is cleared 2 Link to comment Share on other sites More sharing options...

viscount806x Posted February 15, 2017 Share Posted February 15, 2017 Maintenance and parts manuals etc. for the 1C all had DH121 at the head of the pages on the microfilm packages. This was in place right to the last days of service of the 1C ('RPH as I recall, which is/was preserved) in the 1980s. It therefore qualifies perfectly.

Also true but it's not a 'hushkit' as we know it. The 1-11 had hushkits fitted later on late '70s, an obvious addition. 1 Link to comment Share on other sites More sharing options...

It may not be a term that you or I would use, I'd also generally use it to describe a retrofit solution as fitted to 1-11's, 737's etc. However, it is a "bolt on" addition to an existing engine, and as such could legitimatley be described as a hush kit. RR used similar devices on, for example, the Spey (Trident), Avon (Comet) and Conway (707). These engines, as I'm sure you are aware, were used on aircraft without this nozzle/diffuser fitted.

Seems bloody tricky in 1/144 I'd agree with you Pin, exceedingly tricky, and if you do succeed in fabricating one, also not very easy to replicate - moulding and casting would be complicated by the narrow ring surrounding the flutes at the rear of the nozzle/diffuser. I'll be watching closely to see how you get on! Link to comment Share on other sites More sharing options...

All fair comment Dave. My point was picking at the use of the terminology. They were always known as 'silencers' during my long association with the Tripod whereas the 1-11 definitely had 'hushkits' or, prior to modification, it was 'un hushkitted'. Just me being pedantic as usual but that's what being in the industry makes you unfortunately, scarred for life with it probably. It's like calling a desktop icon on Windows Version 1 an 'App' which it surely is in the scheme of things, but yet it isn't. Lets leave this one now and let Pin enjoy making his Hushkits/Silencers.

Pin Posted March 8, 2017 Author Share Posted March 8, 2017 Overlayed known projections with a photo - the extent of the problem is clearly visible Printed to scale As usual, I'm using a can to get straight, sharp edges. Some plastic, superglue and Mr.Surfacer 500 to the rescue Half the job done, the other half is pending But before joining the fuselage I need to rebuild the front leg well 3 Link to comment Share on other sites More sharing options...

Jessica Posted March 9, 2017 Share Posted March 9, 2017 Okay, work backwards. Glue a jig together consisting of slivers of rod cut at a shallow angle and glued onto a flat surface. Cut a strip of beer can and burnish it down on the angled slivers, and once you're happy with the shapes, then roll it up. 1 Link to comment Share on other sites More sharing options...

The cylindric fuselage becomes a cone right before the engine #2 intake (blue arrow), there is a straight line instead of a curve (red arrows) I tried as I could to get it fixed before after Fairings 1 Link to comment Share on other sites More sharing options...
