Terrain Following Radar and the Buccaneer
From a little research it seems that this radar was designed for the TSR2 but that development continued after the TSR2 was cancelled. You'll note that the main trials aircraft is a Buccaneer (S1 - XK 487) which begs the question why wasn't this TFR fitted to the Buccaneers the RAF later operated? |
Bearing in mind just how low some sorties were, at least the RAF Buccaneers, would the terrain following radar have been much use if below 500feet ? It just seems that you'd need very cool blood to trust your life to such a wondrous invention.

Great link thanks very much. This is what I love YT for.

What a great find.

Fortunately in those days it wouldn't have been based on Windows. |

If you're looking for a more in depth treatment then there is:

Available from the South American River but cheaper on AbeBooks YS One aircraft that did get a retrofit of a TFR was the Vulcan in the 1960s. The set selected was American though it had a lower speed restriction than the Ferranti TFR. I understand that the Ferranti TFR was proposed for the Phantom and the ground attack version of the Tornado. In the latter case it lost out to a cheaper American radar. |
The American TFR on the Vulcan had a habit of every now and again of indicating a "fly down" instead of "fly up". It was very unreliable and the pod was changed so often even engine fitters were experienced with the task. It also had the silliest cooling system. The air from outside was passed over the electronics straight from the cooling vents. This was OK when the air was dry but if the aircraft flew through cloud or rain we used to remove the pod and tip it up to let the water run out.

The Buccaneer also did the trials for the Tornado radar and TFR of course.
I remember visiting some of the crews chatting with them in their crew room. According to them it was a more stable platform at low level than the Tornado with far greater legs - but they weren’t allowed to say so publicly. https://cimg8.ibsrv.net/gimg/pprune....aa299376c.jpeg |
It clearly was, it says 30-50 metres was the norm for this TFR and by my reckoning, 30 metres is about 100ft. So why not 500ft? As an aside does anyone remember a UK based flying group that had some ex-RAF jets back in the 70's/80's, painted black ? Did they have a Bucc ? I have a vague memory of sitting in one at Mildenhall or Duxford. They did have a hunter and something with torpedo wing tanks (perhaps a Canadian something ??). What ever happened to Mike Beachey-Head's Buccs when his company was wound up ? |
Ormond Haydon-Baillie had a pair of T-33s, one painted black which he flew as The Black Knight, the other red I think. He also had a Avro CF-100 Canuck at Duxford, though beyond delivery I don't think it flew. It's still at Duxford. One of the T-33s was at Duxford again until a take off accident a few years ago - one of our fellow PPRuNers was at the helm, fortunately he and his pax escaped; very sadly he died from an illness just a few months ago.

As a so called TFR training officer on the Vulcan (many years ago!!) I have to confess (now!) that I had little faith in the system! Yes, it worked (up to a point) but, if it came to the crunch, I would have had some serious misgivings in it at night, IMC, at a few hundred feet and with a "bucket of sunshine" in the bomb bay! However, that was what we had in those days so we did our best, rightly or wrongly! (Sorry guys, for all the b**l that I passed on !!!

What you're all forgetting is that Bucc had TFR when USAF F111s only had Terrain Avoidance Radar for low level ops.

Vulcan TFR at the top of the picture - compare the size to the Ferranti TFR! Don't know if the electronics below it are part of that system or something else... |
Worked with a chap who was involved in the TSR2 radar. According to him it was
tested on a Meteor, test flights always went to height before testing the terrain following capability. |
Orac, interesting photo. I noticed the drooping ailerons, never knew the Buccaneer had them. Was it similar in use as the Lockheed L-1011?
|
Looking for something else and found this thread..... The Buccaneer had small traditional flaps on the fixed inner wing and large Ailerons on the hinged portion with drooped setting for take off and landing. This, in addition to the blown wing leading edge and tailplane leading edge, gave it the performance required for the RN carriers, but the large ailerons provided impressive roll performance
