Airframes that bridged Jet and Turboprop

[speedrestriction]

While reading Eric Brown's wonderful "Wings on my Sleeve" I encountered the photo of a Meteor fitted with an early turboprop engine. It got me thinking about aircraft which have flown as both TP and Jet. The Dornier 328 is the only other aircraft I could think of but have there been others? The more obscure the better! It would be great to hear from anyone involved in such a project and the technical obstacles involved in adapting an aircraft from one engine type to the other.

How about the HP7 Herlald for bridging the piston to turboprop gap. Originally designed with 4 Alvis Leonardes engines but got 2 RR darts

The Saab J21 piston powered aircraft was morphed into the 21R jet powered version.

If you also included post-production variants I think you are looking at a very long list indeed.

You could make the list a lot smaller by only including aircraft that flew simultaneously with both.

[Haraka]

Then make it longer again by including test beds

[speedrestriction]

If you include piston to TP is comparatively commonplace hence the question being TP to jet and vice versa which seems slightly more exotic. Thank for all the contributions so far.

XF84-H Thunderscreech, perhaps?

Although it never entered service, it seems low-level passes over enemy troops might have been damaging in themselves.

Turboprop to pure jet...

Yes, and there was a proposal to redesign and engine the HPR7 Herald with jets, but it never got off the ground. I seem to recall an Avro Lancastrian flying round with a jet fitted on test, was it a Sapphire?, but I might be wrong, and didn't the Noratlas have both petrol props and jets?

B36? Shackelton?

A few did.

[Kitbag]

Didn't the Me262 prototype fly on piston & turbojet due to uncertainty/unreliability of the jet engines.

C-119 with a jet pack

. N15509 - Unknown Fairchild C-119 Flying Boxcar at Chandler Municipal | Photo ID 8034 | Airplane-Pictures.net

These were popular in Alaska for hauling fish

[ancientaviator62]

A C119 used for a rather different purpose than fish hauling.

I'm surprised nobody has mentioned this pair yet:

[Shaggy Sheep Driver]

The Tay Viscount. Had a look of the 737 about it. Based at Seighford for many years. It was the first ever 'fly by wire' aircraft, pioneering the technology.

Vickers 663 Tay-Viscount - research aircraft

What should have been the Mk2 Shorts Belfast.......

[Wander00]

DH - what's that - the Bel(slightly)fast(er)
