The Failed Bomber That Gave Britain The Lancaster | Avro Manchester

[@RexsHangar]

Part 2 of the Wellington video is coming, I promise! (Please put down the torches and pitchforks xD) F.A.Q Section Q: Do you take aircraft requests? A: I have a list of aircraft I plan to cover, but feel free to add to it with suggestions:) Q: Why do you use imperial measurements for some videos, and metric for others? A: I do this based on country of manufacture. Imperial measurements for Britain and the U.S, metric for the rest of the world, but I include text in my videos that convert it for both. Q: Will you include video footage in your videos, or just photos? A: Video footage is very expensive to licence, if I can find footage in the public domain I will try to use it, but a lot of it is hoarded by licencing studies (British Pathe, Periscope films etc). In the future I may be able to afford clips :) Q: Why do you sometimes feature images/screenshots from flight simulators? A: Sometimes there are not a lot of photos available for certain aircraft, so I substitute this with digital images that are as accurate as possible. Feel free to leave you questions below - I may not be able to answer all of them, but I will keep my eyes open :)

A fighter pilot’s experience of the Manchester. After serving in 501 Squadron through the Battle of Britain and the Blitz, the fighter ace Ginger Lacey had to serve six months as an instructor in an Operational Training Unit ~ this euphemistically being called a ‘rest’. Beginning in autumn of 1941, he found this to be not particularly enjoyable or inspiring apart from when the soon to be legendary ’Screwball’ Beurling joined the unit but it did give the opportunity to meet up with his old friend, the former Chief Flying Instructor at the Yorkshire Aeroplane Club, Captain Worral, who had been Sir Alan Cobham's navigator in the latter's flight round Africa in the Short 'Singapore' in 1927-8. In his late 50’s when the war broke out, he’d immediately joined Avro's as a test pilot. Lacey went to lunch with him one day and just as he arrived Worral was about to test a Manchester. 'Sorry I can't take you up in this one, Ginger, but I've got a lot of boffins and flight engineers aboard. However, I've got another one to test before lunch, so I'll take you up with me in that.' Half-way down the runway, when it was too late to stop, one engine caught fire. Worral took off, went round the aerodrome in flames, and landed. He strolled back and said, 'Come on, Ginger, we'll go and test the other one now.' Lacey implied that you couldn't have got him into that second one even with an armed escort. He watched Worral take off again. Half-way down the runway, one engine of this Manchester also caught fire. The pilot flew round the circuit, in flames, and landed. Lacey stated, 'This is a gentleman of fifty-nine or sixty; and not even batting an eyelid: we went straight off to lunch as though nothing had happened.' After this, Lacey reflected that his time at the OTU didn’t seem to have been quite so bad after all….

the MKI Manchester tried the merlin engines at 1st but 2 just didnt have enough power to take off. so they went with the vultures instead. Thats down to the war department saying they could only put 2 engines on it. But with the 2 vulture engines it could fly faster higher and further with a bigger bomb load than the 4 merlin engine lancs could. If they could of sorted out the engine problems the Mancherster would of been far suppior to the lancaster. Even with the probs with the Vultures it still had triple the power the merlin had. The vulture didnt use as much fuel as the Merlin so could go a lot further with the same fuel. Prob was as it was 2 engines bolted together in the same cowling the fuel and oil pipes had a nasty habbit of breaking under the vibrations and it caused the engines to catch fire. USA used Merlin engines in the short range mustangs. Alisons in the long range mustangs to work as bomber escorts. Germany got their hands on a spitfire after the pilot landed at a Luftwaffe base by mistake after he got lost. Germany tried it with the Merlin and found it lacked power. so they put the engine in from an ME109 and found it could fly longer faster. 50mph faster and 100 miles longer range.

[@Sacto1654]

The P-51 Mustang kind of shared the same issue as the Manchester: the early models lacked high-altitude performance due to the limits of the Allison V-1710 engine. It was only when they put in the Merlin 61 (Packard Merline V-1650) engine that the P-51 came into its own as a world-beating fighter.

@@Sacto1654 The Allison was a great engine for the Mustang but lacked the two stage super charger for better high altitude performance.

Apparently RAF maintenance crews discovered if they stripped them down enough metal chips were found that sabotage was suspected. When carefully cleaned atleast some of them worked. (from an article in Aeroplane) not sure which issue. The wing ribs of the new wing were Manchester parts spread further apart at least in the prototype, plus the wing without extra engines was intended for a 2 engined Manchester with more power. Sabre or Centaurus if I remember correctly. Now this is just me but if you look carefully you can see the geometry of the tips seems odd. The leading edge doesn't seem to line up with the wing on the lanc. Don't forget the Tornado (12 guns) fighter also used the vulture. It became the typhoon. The Vickers equivalent was the Warwick.

[@mrjockt]

In addition to the torpedo carrying and the “frictionless” take-off capability, the original design specification for the Manchester called for “shallow (up to 30 degrees) dive bombing capability”.

[@coreyandnathanielchartier3749]

'dive bombing' capability was a requirement foisted upon Heinkel on the He177 Grief as well .....only adds extra weight and complication. The catapult takeoff was an interesting feature which could have allowed over-gross weight takeoffs and increase range or bomb load.

[@jimdavis8391]

Interesting stuff... Firstly, I've never believed that there was much wrong with the Vulture engine; I suspect that it's lubrication and cooling systems, it's installation and close cowling may have been the problem; the Perigrine was excessively close cowelled in the Whirlwind installation. I wonder if the time spent manouvering and assembling bomber formations on the ground and lower airspeeds also contributed. Secondly, I was unaware that the Manchester had been stressed for catapult launch; the resultant strength of the airframe, as well as allowing high bomb loads would also have helped the Lancaster in it's low level capabilities and near fighter levels of manouverability.

[@unqualifiedastronaut6328]

Lubrication issues might well contribute to the tendency of the engine to spontaneously disassemble in-flight. We'll never know what the Vulture might have been capable of since development ended in 1941, allowing RR to concentrate resources on further development of the Merlin. A year of engineering effort might have produced a war-winning engine. After a good deal of work the Napier Sabre became a fine powerplant and RR certainly had the expertise to make the Vulture a success. I recall hearing anecdotal stories of early Spitfires tending to overheat on the ground if the weather was warm. The Spitfires wing-mounted radiator and oil cooler didn't get much airflow from the propeller whereas the Hurricanes centerline radiator and oil cooler got a good blast of air. I'm not aware if this was ever resolved on Spitfires.

[@givenfirstnamefamilyfirstn3935]

Cobbling two V-12s into a X-24 was the fundamental flaw, each halves’ coolant pump intake competed meaning one intake had cavitation and the X big ends used a radial engine type master connecting rod with three 90 degree angle slave rods articulating off it. The big end bolts just snapped despite three different big end designs. The main bearings also failed! Rolls Royce were keen to drop it.

The serviceability statistics from squadron records suggest that the Manchester bomber was becoming reliable enough to continue in service, while the Lancaster replaced it slowly on the production lines. So that was what happened. Eventually most remaining Manchesters were broken for parts and fed into the Civilian Repair Organisation's process, and used to rebuild Lancasters that had been damaged.

Well done video on a bravely conceived, but unsuccessful aircraft. At that point in aviation history, all of the airframers and engine companies were learning (the early B17s were no great shakes and neither was the Douglas B18 Bolo) but, as you said, the Lancaster sprang from the trail of exhaust sparks and broken con-rods left behind by the Manchester.

It wasn't so much the manchester that failed, as it was the Rolls-Royce vulture. The modified manchester as Lancaster is foremost contender for best British heavy bomber of WW2 of course. Presumably if Rolls-Royce had had more opportunity to develop the Vulture, it might have been good, but the four Merlins turned out more than good enough and from a manufacturing perspective it was likely more efficient to produce a single engine design for the sake of economies of scale, and the development refinements with that engine could then benefit more aircraft.

[@grizwoldphantasia5005]

The Lancaster bomb bay, low but long, has always puzzled me, compared to the alternative B-17/B-24 full height with stacked bombs. Neither one seems to have any advantage during bombing itself. The long uninterrupted Lancaster bomb bay did accommodate the Tall Boy and Grand Slam bombs, but that was pure chance; the bombs were designed after the bomb bay. But there is one crucial flaw in the Lancaster bomb bay: no access to the bombs during flight. It meant the bombs had to be armed before flight, making takeoff problems deadly, and the crew couldn't safe or get rid of hung bombs before returning to base. So why didn't the floor between bomb bay and crew compartment at least have some access holes? That floor must have been mostly sheets of aluminum with beams providing the strength, so why not get rid of the sheets and allow access? The cabin wasn't pressurized. Wind with the bomb bay doors open couldn't have been any worse than a B-17/B-24. Designers weren't stupid, so there must have been some reasons which I don't know. Does anyone else?

[@allangibson2408]

The American bombers took off with the bombs armed too. The shortcoming of the stacked bombs is a jammed bomb release at the bottom can potentially jam all the bombs above it. The requirement to carry torpedoes defined the length of the bomb bay on the Manchester. Germany went another way with all bombs supported by the nose and dropped tail first. The B-29 atomic bombers were fitted with bomb suspensions from Lancaster bombers (because the Lancaster had a history of dropping bombs as heavy and big as the first generation nuclear weapons).

[@grizwoldphantasia5005]

@@allangibson2408 I have seen too many reports of arming bombs in flight to think that takeoff with armed bombs was common. The Lancaster bomb bay was long not to carry one torpedo, but to carry two in a row. B-25s and B-26s could carry torpedoes too, and I'd bet so could a B-17. I've never understood the German method.

I believe that there was a manual crank if hydraulic power was lost - that was for Lancs, if I can assume it was the same for the Manc and other British planes with hydraulic turrets? It was accessible in the straight astern position into the fuselage, but it was tight, hence parachutes were sometimes left in the fuselage.

Great work Rex

[@ricardodavidson3813]

The main cause of the problems with the Vulture was that the inter-cylinder spacing was not changed from the Peregrine, probably for reasons of economy as it allowed the use of Pergrine components and kept the engines short. This did not release the lengthwise space necessary on the crankshaft to insert another con-rod serving the other two cylinders. Con-rods thus had to serve 4 cylinders in a very tight space leading to bearing overload (even if the diameter was increased) and lack of rigidity. Bolting the two halves of the con-rod big-end with sufficient strength was another issue, RR went as far as crosshatching the mating surfaces and machining the assembled con-rod. The cross-hatching supposedly would take part of the shearing forces over the whole mating area sparing the slender bolts. There's a booklet about this by a chap called Rubra, he was one of the RR men involved. Basically a designed tragedy. I'm surprised they did not think of using the Bristol Centaurus which was reaching maturity about the same time and would prove to be a superb engine. In fact, the way the Centaurus was "conveniently" left on the shelf, as was the Fairey Monarch are stories worth telling in themselves, the mafia of the big engine manufacturers was almost as self-destructive as the palatial intrigues at the top of the RAF.

Putting more than 2 cylinders on the same big-end normally calls for a master-and-slave arrangement as in radial engines or W engines (Napier Lion). In this latter situation the stroke of the lateral banks is different from the stroke of the central bank. Going up to 4 cylinders on the same big-end seems complicated. Engines were made with 5 banks distributed like a radial engine, and that seems to have worked.

[@givenfirstnamefamilyfirstn3935]

Yes, master rod but the big ends were big and gave a lot of trouble.

[@brianedwards7142]

Interesting that in the 30s they still had to specify a monoplane configuration.

At first, I thought you meant the bathroom was soundproof. 🤣

[@givenfirstnamefamilyfirstn3935]

There was always a chemical toilet the use of which usually triggered violent manoeuvres by the pilot.

[@HeliophobicRiverman]

Considering that the RR Vulture messed up the Hawker Tornado while the Napier Sabre powered the Typhoon and Tempest to success (after the Typhoon's fuselage was fixed), I can't help but wonder how a Manchester powered by Napier Sabres would have fared. And considering how common it was for British aircraft manufacturers to build or at least develop multiple versions of the same airframe to use different engines, it strikes me as odd that the Manchester didn't get that treatment.

[@unqualifiedastronaut6328]

Interesting thought. Possibly Sabres were not available in sufficient numbers, but they would certainly have had the power with early Sabres developing around 2000HP. Interestingly, a successful Manchester might have removed the impetus to develop the Lancaster, which might have seen a world without Lincolns, Shackletons, etc. Considering that Shackletons served the RAF into the 1990's it might be said that the Manchester was the most successful failure of all time.

[@wbertie2604]

Fuel in the wings also allows trim to be stable as fuel is used. Given the maximum range specified, quite a factor.

[@alessiodecarolis]

It's incredible how differents was the approach btw RAF and RLM, about the problems that plagued either the Manchester and the HE177. The British changed the engines and added two more ones, plus improved the hull, on the contrary the germans endured in their errors, keeping the two coupled engines configuration, source of overheating problems, plus the fooly of trying to made a 60* dive with an aircraft too big for this kind of action. So the RAF had the Lancaster, and the Luftwaffe a less than stellar bomber, which production was stopped in 1944.

[@scrumpydrinker]

Rex, the vulture wasn’t completely an utter waste of time, one was used as the power source in the development of Whittles jet engine compressor. It had the power to drive, through a pair of Merlin prop reduction gears which were reversed and combined together to give a step up gearbox the compressor assembly at its design speed so aiding its development. It also donated its centrifugal compressor as the second stage of the two speed two stage compressors fitted to the 60 series Merlins.

[@londonalicante]

That sounds like use of surplus (not-fit-for purpose) equipment findng an alternative application. Similarly, the Napier Lion was used in several historic speed records when it was way past its prime. (On the other side, there are of course cases today of tractor pulling teams trying to buy WWII engines and being told "we're not selling it if you're going to do THAT with it.")

[@paulkendall6069]

The failure of the Vulture engine was truly a hudden blessing as it resulted in The evolution of the Manchester to Lancaster, I did read the name Manchester was dropped as it had too many bad marks against its name and a new name was needed. From memory the Wellington that the Manchester was supposed to replace carried on in service till the end of the war tho that was mainly as a a target or glider tug. If only someone had kept a Wellington, Halifax and Stirling flying with the Lancaster I would also love to see a flying Mosquito. My big miss at air shows is the Lancaster's replacement the Big Vulcan which for a huge plane was very fleet of foot with a deathning howl and roar contrasted nicely with the Lancaster's Merlins rithmacly humming away both have an uncanny grace in tha air.

[@ronjon7942]

Were there ever any conversations early on in design to use the Manchester as a basis for a four-engined bomber, or was the Lancaster just that fortuitous? If the latter, then perhaps the Vulture unknowingly made a huge contribution to Bomber Command. A shame about the Vulture, such an impressive concept, it must have been exciting to be assigned to that project. I hope it didn't curtail attempts at similar future projects-I know there were some radical approaches like the Sabre, combining Merlin blocks, etc, but I wonder if there would have been more, despite Britain being in the thick of it and having to prioritize Merlin production.

[@mrjockt]

I don’t know about Avro but Handley-Page managed to get the Air Ministry to agree to their HP56 design using four Merlin engines instead of two Vulture’s, mind you Handley Page wanted to use Bristol Hercules engines but the Ministry insisted on Merlin’s because the Hercules was needed for other aircraft.

[@jacksavage4098]

Really enjoyed this.

[@waitotong9590]

You know the engine was not designed well when it tended to leave a stream of exhaust sparks

[@ScottM3]

Thank you. I enjoyed that. I would love to see a deep dive into the Stirling. There is not a lot of in depth information out there.

[@Deviation4360]

Those windmills on the Vulture are much larger than they first appear when you then jump straight to another shot of the Lanc with the Merlin props. I always thought the Lanc props were pretty large for a Merlin engine compared to the fighter Merlin engine propellers. The Vulture engine props must have been the ones to be used on the Typhoons with Sabre engines of similar to Vulture power.

It’s like the other failure featured before: from the F2F to the F3F to the F3F which developed into the F4F and finally developed into the venerable F6F. evolution matters, it was a dud due to issues not the plane’s fault but it begat something epic

[@garryferrington811]

Basically sound design, ruined by a bad engine. But the Lancaster came out of it.

[@elennapointer701]

Convergent evolution springs to mind: two heavy bombers, both sporting a double powerplant inside a single nacelle. On one side, the Avro Manchester. On the other, the Heinkel He-177 Greif. Same (or similar) problems on both: unreliable engines leading to thrown cylinders or engine fires. I don't know if the Manchester acquired any (printable) nicknames, but to the Luftwaffe aircrews unfortunate enough to have to fly it, the Greif became knowns as the "Flaming Coffin". A terrrible idea for a powerplant either way.

[@Kevin-mx1vi]

The Grief's problem stemmed from shoehorning two engines into one nacelle, leaving little room for the other things engines need to work properly and them being put wherever there was a bit of space. The oil tank was thus put at top front of the nacelle but often ruptured due to vibration, spilling its contents all over the hot engines with predictable fiery results.

[@allangibson2408]

@@Kevin-mx1vi The Greif could have been fixed exactly the same way with four engines from the current fighters of the time too. The DB605 was a perfectly good power plant (or even a Jumo 207).

[@Kevin-mx1vi]

@@allangibson2408 Indeed. The Grief's problems all stemmed from from having two engines and its landing gear squeezed into too small a space. The idea - reduced drag - is fine, but the execution was flawed. Aircraft design is a matter of balancing compromises, and in this case the compromise wasn't great enough. Was it a failed experiment or a fatal error ?

[@kringe700]

@@allangibson2408 That's basically the He 274 or the reportedly He 177 A-4, which is basically the Greif outfitted with four DB 605 engines instead of two DB 610. (Un)fortunately, the Luftwaffe insisted on trying to fix the DB 610 problems, which caused both variants to never enter services.

[@allangibson2408]

@@kringe700 The He 177 had DB606 engines (twined DB601’s). Most of the problems came from a lousy engine installation however with too tight a cowling. The DB610 came later. The He177B was fitted with four DB603’s but when they got the aerodynamic bugs out (exactly the same ones that plagued the Manchester in 1941) in 1944 it was just too late.

[@fredbloggs5902]

A demo of ‘real life’ use of Squarespace would be very interesting.

[@mandoprince1]

It is interesting to note that the Handley Page Halifax was originally designed to the same specification as the Manchester, but the Air Ministry instructed Handley Page to redesign their aircraft to use four Merlin engines (in 1937), due to doubts about the Vulture's reliability and performance. According to aviation author Phillip J. R. Moyes, this redesign to four Merlin engines had been done "much against the company's wishes".

[@dougscott8161]

Hi, Rex, a while back you mentioned going to more coverage of jet powered aircraft and were considering using a jet engine start up in your intro's, I think the piston engine start up that you've been using all along is much more pleasing to me, please stick with that. Thank you and God Bless.

[@iskandartaib]

The Lancaster might be grateful to the Manchester to rule out the airframe design flaws, which allowed the Lanc to be successful from the start. In a certain way, the Manchester had to bear the dubious honor to serve as the Lancaster testbed, that being a merit in its own right.
