Will give 110%

I dunno if it’s a valid gripe. The CFM-56 has a limitation of 104% N1 and 105% N2. I spose I should ask some knowledgeable bugger why not just recalibrate the bloody instruments to 100% and be done with it.

Very good point Capt. I have had the same with other aircraft. Down here as our S.A. friends will know they describe a good situation as 100%, no more.

[belfrybat]

Principal when they mean principle and vv.

[llondel]

There's always that American corruption of "the aircraft will arrive momentarily", which I always think of as a touch-and-go. Worse if it's arriving in such a manner at the gate, that means it's going to bounce off.

Alright is not all right. It's alwrong.

The Bristol Olympus, pre Concord came in 3 flavour, 101-104 fitted to the Mk 1_Vulcan, 201-301 fitted to the Mk 2. Now each had two power settings, take off and cruise. I can't remember the fine detail but remember the 100% argument back in the '60s.

Full power range in cruise was from flight idle up to full power which delivered something like 98%. In take off power the 200 series would go to 101.5% but the 300 series went to 104%.

Quite why we needed the two power ranges I don't know. As the 300 series delivered about 2,500 lbs static thrust (2,500x4) but with slightly lower take-off weight you could say it was overpowered and for fatigue reasons we were eventually restricted to cruise power for take off.

I suspect, as you suggested, it was all based on the initial 101 engines.

One I missed out.

Besides peek and peak there is of course pique!

I was fortunate to be on board as 6th seat when 1GSU were tasked with some trials on the 301 series engines. The selected aircraft had, I believe, 3 x 201 series and 1 x 301. We went up to height, throttled back the 201s and let rip with the 301. The flight test was obviously satisfactory as, within a short space of time, the limiting Mach number was reached with just the one donk pushing us along.

[Pontius Navigator]

Interesting, the exhaust stubs were quite different. The 301 was shorter and wider. You could slide the jet pipe out through it. To slide the 201 out the stubs had to be removed.

I wonder if the designers in the make it hard to service department got more pay than the make it work department?

[Sisemen]

I believe that the intakes were a slightly different shape also. Maybe that particular frame had 4 x 301s? I do know the test was to see what just one could do.

Nerd alert!

Wasn't the 301 later derated resulting in 18,000 lbf (dynamic) as opposed to the earlier rated 22000 lbf original specification that was restored during the Black Buck raids?

I think the thrust was 21k whereas the Conway was 22k but that is from the top of my head.

Not derated but restricted to cruise power for take-off. Take-off power was unnecessary and whilst impressive it was at the expense of engine fatigue like. I believe it is now normal for civilian aircraft to set the required power for safe take off rather than full throttle. Correct me if I am wrong.

That is tough on rough kids not brought up proper. I went to a posh school that had wrought iron railings before the war.

PN I appreciate the take off thrust limitation to reduce noise, engine wear, fuel burn and increase engine life versus max thrust on take off, and other stages of flight, paradigm which now applies to even small twin-engined corporate jets, such has been the progress that has been made in the world of the growth of the thrust of jet engines, and fully accept that the 301 engines were so powerful that this would have applied as you say.

However I am sure that I read in some Rolls Royce journal that the 301 was actually later derated in an engineering sense. I may, as I so often am, be totally wrong. Being a nerd (can anybody suggest a more acceptable English word that encompasses the spurious fact, technically fixated, mono-thematic, possibly slightly insane etc. bore), I will see if I can find where my thought/possible mistake arises.

[Pontius Navigator]

Olympus Mk 301
(BOl.21) Additional zero stage on LP compressor. 21,000 lbf (93 kN) thrust.[34] Later Vulcan B2 aircraft plus nine earlier aircraft[N 2] retrofitted.[35] Later derated to 18,000 lbf (80 kN) thrust.[36] Restored to original rating for Operation Black Buck.[37]

Fair enough. I left long before BB. I will ask a friend why they needed to up rate it.

Why? Did Ap bung you on an enforced diet too mate?

It wasn’t till I joined SQ that I realised English is one bloody hard lingo to learn with all its ‘exception’ rules. If Asians misspell here and there it doesn’t bother me...so long as the idea gets through to my brain clearly.
