The Westland Welkin; Whirlwind’s High Flying Sibling

[@donjones4719]

Nice to see more ancestry for the English Electric Canberra - a version of which is *still* in service with NASA. The Welkin's designer did good work. The Canberra was license-built by Martin Aircraft in the US. A version was developed as a reconnaissance aircraft, the WB-57F. This has a very wide wingspan. Three have been used by NASA for years for a range of duties and are now used for photographing high-priority launches such as crewed spacecraft and their reentries. Its military service life was extended into at least 2011. The Air Force borrowed one from NASA to test a new sensor suite over Afghanistan.

[@anzaca1]

The Caberra was designed to be the jet equivlent of the Mosquito, and it was. When introduced, no fighter could touch it.

[@jonathangriffin1120]

Great video! I knew of the Westland Whirlwind, built an Airfix model back in the day, not the Welkin. One of those 'odd bombs' dropped by a JU 86 was dropped on Bristol, it hit a car with a full tank, which must have been a rarity back then. The resultant conflagration spread to a bus and caused considerable loss of life.

[@richardjamieson6681]

Nice one Ed. I already knew quite a bit about the Welkin as my father built a model of one of these back in the 70s as he'd seen them flying during WWII so I naturally took an interest of my own. The kit was vacuum formed (by a manufacturer called Contrail) and incredibly basic, requiring hours of cutting, sanding and filling. My Father's still with us and this is one of the things he still remembers doing so I'm going to build the modern equivalent by CMR (not a vacform thankfully) to keep with tradition.

[@johndell3642]

Another great video Ed! - It's worth mentioning that Petter helped George Carter of Glosters with the design of the pressurised cockpit of the Meteor jet. Ironic, because the Meteor was another reason why the Welkin was no longer needed - it had excellent high-altitude performance and could climb to height a lot faster than the Welkin. Post-war all the experience Westland had built up developing high-altitude technology was separated off into the "Normalair" Company

[@EdNashsMilitaryMatters]

This is why I should come to you before posting videos John 😂

[@soppdrake]

What the dickens? What a beauty! Never come across this weird aeroplane before and would like to say thanks for the heads-up!

[@davidd708]

Just a note regarding the relevant aerodynamics - compressibility comes from Mach number, not airspeed or groundspeed. Because Mach varies with altitude (same actual speed over the ground equals higher mach at higher altitude due to temperature changes), you get compressibility "earlier" at higher altitude. Meanwhile, the same true speed "looks like" lower airspeed to a wing at higher altitudes, because the lower density air provides less lift (and less drag) for a given airspeed. This leads to a "coffin corner" where the aircraft needs to fly faster in order to maintain lift, yet adding any speed causes mach limit issues. That "coffin corner," where those lines converge, is often the reason for an aircraft's ceiling. High aspect (long and slender) wings help with the lift part, but if materials requirements mean they have to be extra chunky, the compressibility gets worse. Just 15 or so years later, the U-2 would use extremely long, thing, and NON-chunky wings to get its coffin corner up to ~80k feet.

[@leakycheese]

The name “welkin” has an interesting meaning- well worth looking up. Thanks Ed for another great video 👍

[@robertmarsh3588]

Great video again! Excellent point re the 44,000 ft interception by a high flying Spitfire. A perfect outcome really, with the German crew making it home to tell the tale.

[@philhawley1219]

The Junkers only got home because one of Galitzines two 20mm cannon jammed and ever time he fired the good one it threw his Spitfire into a violent spin.

[@loopernoodling]

It has to be best part of 60 years ago, but I definitely remember a great Biggles story about trying to catch a high-altitude intruder! It was probably in a stripped-down Spit though - much more Capt. Bigglesworth's style.

[@thesmallerhalf1968]

The original Biggles story came from WE Johns’ WW1 stories, I don’t remember which book, but I am sure I have it somewhere. It involved Flight Sergeant Smyth adding extensions to the upper wing of a Sopwith Camel, and reducing it’s weight. It worked in respect of altitude but made the Camel a deathtrap in a dive. Biggles victory ended in a crash landing.

[@casinodelonge]

@@thesmallerhalf1968 I agree, in my 20's, I was a Biggles aficionado, I think I had about 80 of the books. Although its upwards of 30 years since I read them, I am pretty sure that this was the correct version of the story, although it may have been re-worked in a WW2 setting, I wouldnt have put it past him. I still reckon Biggles Flies West would make an ace film!

[@sim.frischh9781]

Welkin is noticable close to the german word Wolke, meaning cloud as well.

[@rosiehawtrey]

Welkin is a Saxon word, the Anglo Saxon language was basically a modification of ancient/old high German, so that makes perfect sense. A lot of English "low" words (like mother, brother, sister) are Saxon derived where others are from the French (Beef, Pork and others).

[@harryspeakup8452]

Yes... there weren't any reverse-rotation Merlins until the 130/131 pair for the Hornet

[@anzaca1]

The interesting thing about such high-altitude, pressurised aircraft like the Junkers, is that the Welkins wouldn't have even needed to actually shoot them down on their own. All they would've needed to do was compromise the pressurisation. This would force the Junkers down to an altitude that normal fighters could reach.

[@EdNashsMilitaryMatters]

Indeed. The Mosquito XV I mention only had 4x.303 machine guns. Guess that was considered enough to put holes in a ju 86.

[@gort8203]

Loss of pressurization would not force the aircraft to descend while over enemy territory. I think a little discomfort is preferable to risking interception. The cabin altitude while pressured was already 24,000 feet. The pilot had been breathing oxygen long enough to purge much of the nitrogen from his tissues.

[@anzaca1]

@@gort8203 Yes, it would. The crew would pass out briefly, if they weren't wearing oxygen masks.

[@anzaca1]

@@gort8203 You're wrong. The Ju 86P's cabin was pressurised to 3,000m (roughly 10,000 feet). Above such altitude, most people quickly lose consciousness.

[@gort8203]

@@anzaca1 I thought the video said 24,000 feet, but I guess that was referring to the cabin altitude of the Welkin. But even if the JU 86 was pressurized to 10,000 feet, each crewmember would still have their oxygen mask immediately available and don it immediately if pressurization was lost, so there was no danger of losing consciousness. This is standard practice in all pressurized aircraft flying at high altitude for obvious reasons.

[@iancurtis1152]

What was the purpose of the appendage aft or the fin? Was there an installation in it or purely aerodynamic?

[@johndell3642]

Excellent question - It was purely aerodynamic. It was an early example of what is now called an "anti-shock body" - to smooth out the airflow disturbance aft of the junction of the tailplane and rudder. Petter was one of the first to use such a system, - the "bullet" fairing on the intersection of the tailplane and rudder of the Whirlwind was another example. - It's strange that Petter seemed to have just come up with the idea intuitively and used it without any accompanying research, it was only later in the 1950s that Richard Whitcomb at NASA and Dietrich Kuchemann at the RAE came out with research to explain why it worked.

[@surferdude7013]

An interesting video. I remember reading somewhere of another "snag" at extreme altitude, where the speed of sound is slower and lift from the thin atmosphere less. Due to the span, in a turn the inner wing could stall and the outer wing, travelling faster, approach the speed of sound.. ?? ???

[@FinsburyPhil]

A really elegant aircraft - like most of Teddy Petter's designs. Surprising that one or two weren't kept on post-war at Farnborough or Boscombe Down to continue investigation into high altitude flight and compressibility.

[@JohnyG29]

They had jets by then. That's why.

[@FinsburyPhil]

@@JohnyG29 There was still a lot to learn about aerodynamics and wing design that wasn't dependent on the propulsion unit. The Meteor III had a critical Mach number of only .74 and a fairly low operational ceiling as it's rate of climb dropped considerably above 31,000ft. The Welkin didn't just fly high, it was designed to fight at altitude so there was plenty of good data to be had.

The big lesson Petter learnt was that fat high aspect ratio wings were no good for high altitude flight (unless you didn't need to manoeuver) Canberra set many altitude records with its short thin wings.

Petter did work on a high-altitude night bomber conversion of the Welkin. It would have had a second crewman to work a "Gee" navigation aid and a forward-looking version of HS2 radar in the nose. It would have carried no cannon armament, instead carrying two slim 2,000 Ib bombs. In 1944 Petter fell out with the management of Westlands but the RAF arranged for him to move to English Electric and take his design projects with him. At English Electric Petter continued to work on the high-altitude Welkin bomber design- first increasing the chord of the wings and then replacing the Merlins with jets - the result was the Canberra, and of course, the Canberra was the pre-eminent high-altitude recce aircraft of the RAF through the rest of the century.
