The Secret Horsepower Race by Calum Douglas (and piston engine discussion)

Some may find this nitpicking but as a chemical engineer working at an American design company (retired now) I have seen through the years many mistakes being made with gallons as most of my coworkers, especially the younger ones, automatically assume that a gallon is 3.785 liters, even if it is mentioned in a clearly British document. I therefor have always urged coworkers to be careful when reading a document, and be clear which gallons one means when writing about them.

...Assumption is the mother of all f#ck-ups.

Not just an American issue. I worked for a weighing machine company in the UK making equipment designed in Germany, the US, the UK and Italy. Having OCD I ended up buying the fabrications for spares for this zoo. Some of the drawings dated back to the 1860s and are still in use today.

IIRC a US probe to Mars hit the planet at very high speed due to a mph vs km/h error and the French lost an Arianne because the payload was designed in inches then converted to mm.
BOT I found out about this book two hours ago and now it's the most important publication of the year!
 
I would like a signed copy. I pre-ordered long ago but when I log on to the Morton's site I cannot find any menu item / link for existing orders. Is it possible to:
1. Check whether my pre-order has not been forgotten?
2. Upgrade it to a signed copy?

If you ordered a long time ago from Mortons, it will 100% be a signed copy.
 
Man, Amazon just let me know their ship date is now Jan 7, 2021. I have plenty to read until then. just saying.
 
I am just looking forward to it getting here whenever it does arrive. I think worrying over it will do no good, nor will listening to amazon/google etc. When have they EVER made sense?

I know that "yea but covid" is the new "go-to" phrase for anyone who has done anything late, but in this case its been a disaster. I lost my income in March, and... {boring story removed}
we`re genuinely fortunate the book exists at all in print. Its been really touch and-go a few times. Many many authors have who were only very slightly
less far advanced through the process have had their books cancelled or put into "limbo" (I`m not referring to my publisher specifically there). This book was secured principally because it had so many early pre-orders, so essentially it was actually safeguarded by the prospective readership.

I`m not exactly "Len Deighton" or "James Holland" (i.e nobody knows who I am) - so had there been no pre-orders the publishers would have had no guarantee if they would make money.

Going on 40 years in the book business, our publisher has the experience to plan through the "yea but covid" situation. I have only been brought back recently. I do sympathize with what I see happening to other authors and their books. Word of mouth is as important now as in the past but a steady stream of updates and promotion are required. The internet has not made some things easier or obsolete.

I'm sorry you have been hit by this situation, many other too. I wish the very best for you and yours, we need folk like you who are commited enough to research and write these wonderful books. In my own not so humble opinion, those who do not read these books are losing out on an insight into something we mostly take for granted, the Internal Combustion Engine. I do not concern myself with the so called information produced by amazon or google or such, they have many times messed in their own systems and left customers wondering just wth is going on. BTW, Len Deighton or James Holland writing an engine based and factual treatise? No thanks.

After all, I'm not exactly going on holiday am I? That being said, when it arrives I will be one more happy hamster, in my straw bedding and reading happily. Wonderful.
 
He is a far better fiction writer though and perhaps I should have said something else instead but nothing comes to mind. One day I shall stop treading on my own bottom lip, maybe.
 
No worries . . . I only posted about it because I had the book and read it many years ago. It's one of those 'Not a lot of people know that' facts that Len Deighton wrote non-fiction books. It was from 'Fighter' that I first learned that it was structural strength, rather than aerodynamic efficiency, that allowed a Spitfire to out-turn a 109 . . .

cheers,
Robin.

"FIGHTER" - was I thought pretty good in the "historical easy-page turner" category, and I thought (mostly) reasonably accurate technically as well - although the argument about turning circles appears to be still raging to this day. Lets not start that one again here !

The only bit I do remember him getting plain "wrong" - was mixing up two-stage and two-speed superchargers.... which is a very common one people get wrong. (Although I`m not
really sure how as the number "two" is the only common factor between them... anyway)

Until now I had never heard of Len Deighton or James Holland, but that's probably because I neither read fiction nor war books.
I'm interested in planes (design and development, aerodynamics, engines), not so much in war.
From reviews on amazon.com I get the impression that Holland's books are not worth the time and money.
Deighton's Fighter book however seems to be interesting so I just ordered a copy. Thanks for mentioning it.
I intend to order your book as soon as it is available. Didn't pre-order due to bad experience with that in the past (was not with Mortons though).

Its a good read, very well written and much better researched than modern "popcorn" aviation books. Not perfect, but then neither is my book !

You`re pretty safe now with my book, 2000 copies are in a crate in portsmouth right now. Unless it gets torpedo'd in the harbour
you`ll get one. :)

You raise an interesting point about reviews, as far as I can see almost everything gets 4/5 stars on average. Sometimes I read all the
1/5 reviews and see if they seem cogent. Whats your tactic ?

Reviews on anything are a minefield so unless the people writing them know and understand the topic I ignore them completely. I learned a while ago that film marketing people were editing reviews of film critics so that "Not exactly a blockbusting action adventure", becomes "The blockbusting action adventure you have waited for". I have read and re-read the Dark Tower by Stephen King multiple times and bought the film. The fact that Ron Howard had a lot to do with it made me think it was going to be fair and the cast looked good too. Result? One of the worst time wasting piece of dross I have come across. Unbelievably there were reviews in the four and five star range. It just goes to show that when reviews are available to anyone you will get all kinds of junk as a result.
 
When it comes to reviews I try to find the names of people who've reviewed books that I like and have read and see if they have reviewed books I'm thinking of buying. I also have a reliable group of friends who can give me the lowdown. Not to mention, if it's aviation related, I can usually find honest reviews here. ;)

Sometimes you can even find a deal. I was looking for a good book on the mathematics of lofting, as used in aircraft design, and I happened to run across a good reference from a former aeronautical engineer and it's been out of print for decades. But I think I snagged my copy for around $15.00 USD with shipping from a used book store. I think it's more than worth it's weight in gold, lol.
 
Reviews can be tricky. I've read negative reviews of books on projects which say "its just a bunch of drawings and models of things that that never got built'. Well, yes.

My idea of a good book on an aircraft has a lot of text with detail on development and technical aspects, and less operational coverage and photos of aircraft in action. I appreciate that's not true for others.

Other people just want lots of photos for modelling, or loads of pilot stories. Its all good, provided it's clear before you buy.

A good non-fiction review shouldn't pan a work for failing to meet your expectations, it should be an accurate description of the contents of the book and your assessment of the quality of that contents, and how it compares to previous books on the subject, such that other people can judge for themselves if the contents are of interest.

Probably not much different from yours. I first read the 1star reviews, then 2star, et cetera. Of the 3star, 4star and 5star reviews I usually only read the really long ones.

Exactly my idea too.

On the ww2aircraft forum there is a topic (a new book in my library) that is almost 400 pages long by now, where I mainly see books that I would not even want for free if I was forced to read them. Apparently there is a market for them. That's fine with me, but not for me.
 
As a book publishing professional, I am seeing all of the hallmarks of a readable, well laid out book. Not to mention the choice of paper stock. Well done.

I dont deserve all of the credit for that, Dan, Steve and Jayne at Mortons did most of it. We did try extremely hard to make it a very high quaity print, which was
very challenging. As, to be honest, for a low volume hardback of almost 500 sides A4 (ish) the price is rather low. We feel the result is an exceptionally good
price to content/quality ratio book for the reader. Books of similar size from people like SAE, often go right in at double the cost of this, then vanish from print.

I think people who compare it to other books of similar size will find this one punches far above its price-point in terms of print quality and content. (I suppose
all authors say that dont they ! ;) )
 
Well, many authors send in their manuscripts and leave the rest to the publisher. Someone has to understand page layout, how to select a typeface and so on. I learned the production side long ago, and it helps to have direct contact with a quality printer who will explain it all to you. Some things never change, such as photo and art reproduction. Right now, low volume is all we can do but I have experience with the high volume side as well. As far as books vanishing from print, I've seen too many end up in the hands of speculators who go for sky high prices. One book in my collection was at $30, went to $300 and then dropped back down.

And finding a printer that is low cost and high quality takes time. Prices can vary widely. Fortunately, our primary printer has kept quality high and costs low for decades.
 
Even with CAD software, they have given up supplying a printed manual as the cost was exorbitant.

Disgraceful in most cases, a single seat of CATIA with a few tool-bars added is literally enough to put a deposit down on a house... anyway... thats a rant for a different forum.
 
I am reduced to trying to recreate a Tatra 103 with Sketchup and that is expensive enough. Oh well more research material coming soon so I will have a wealth of that at least.

Just order my copy of the book. Amazon (USA) said they would ship it at the end of the year. Anyone else have this issue?

The books come to the publisher in the UK in bulk on a ship from the printer. These are now with the publisher, and they are already sending out books to customers who ordered with them. Amazon and other wholesalers buy bulk from the UK pubisher to be distributed in their own networks. Thus, these bulk orders (many, many hundreds of books) are sent to the USA by surface vessel (i.e boat) in one big consignment, which is then all unboxed and individually sent to US customers in the Amazon US distribution centres. This means it takes longer for people like yourself to actually GET the book, because of how the commercial distribution networks function.

So the books ARE being shipped to you right NOW, its just that its a longer and more convoluted journey. Amazon dont tell customers about the supply network before THEY get the bulk consignment, so it "appears" as if they`re just sitting in a warehouse doing nothing. However, this is not the case.

Some books, which are more cheaply produced (i.e. "print on demand") dont always have that problem because there are many different sites worldwide which can print them (or at least one on each continent), so the books in that case are turned from digital to real in multiple locations. This would result in a considerably more expensive book, and of lower print fidelity, than you get if you work with one very good print-house and do large bulk print-runs. So its all a compromise.

Its all very annoying, but sadly not anything I can accellerate.

Rest assured, all 2000 copies are printed, and are right now being shipped to everyone who bought one.

The same problem occurs in my profession with pressure units. Some people automatically assume that psi (or kg/cm2, or bar, or kpa, or Mpa, or ....) means absolute pressure, while others automatically assume it is gauge pressure. I have always insisted on my projects that everybody state either psig or psia, not psi, also clients. Assumption is the mother of all f#ck-ups.

In the top left corner of the two page preview there is a quote in which psi is mentioned. The numbers are big so in this particular case it does not really matter whether psig or psia is meant.
However there may be pressure data in the text of your book where psi (or kg/cm2, or bar, or kpa, or Mpa, or ....) are mentioned and where the number is small enough that it does make a difference whether psig or psia is meant.
Maybe you can think about that and let us know how to interpret pressure data without an a or g in your text before we start reading your undoubtedly interesting book.
It's a little off-topic, but a classic case that came from using the wrong units was the now-famous "Gimli Glider", the Air Canada Boeing 767 that ran out of fuel mid-flight and had to make an emergency deadstick landing, which was successful only because one of the pilots had flown gliders in his past. The fuel amount had been calculated as "pounds" instead of "kilograms", and the aircraft only had 45% of the total amount of fuel needed to read its destination. The full story is at https://en.wikipedia.org/wiki/Gimli_Glider.
 
Calum,

Congratulations and thank you for describing how the distribution system works. Although the company I work for uses print on demand, books such as yours are not good candidates for this. The lower quality is not worth it.
 
Some pre-publication critisism has appeared on 12-O'Clock high forum, which is it seems not open to new registrations so
I cant address it. Apparenly:

a) Dr Kolllmann wasnt in charge of design at all, he was just a designer and Friedrich was chief designer
b) The original Daimler-Benz engineering reports are all gone so how can I claim to have used them.

Ref: a:

Friedrich was in charge of Design & Development a far broader role, not Design - Kollmann WAS, and his responsibities
covered piston engines, superchargers AND Jets.

Kollmann did not ascend to this role until late 1944 (prescise date is difficult to ascertain), hence any
paperwork predating about October 1944-ish will indeed not show the correct info.

(BIOS-ER-539 16th April 1946)

Ref: b:

If you actually put in some effort its not that difficult to find all the
DB technical files.

I received my copy today, that's not a book, it's half the encyclopaedia Britannica! In one volume! A quick flip through only so far but it will take a bit of reading so I'm in for the long haul. Imho, for the money, this is great value. The dark age of tanks was £20 and is nowhere near this beast of a book. To Callum and the team, brilliant job done, I hope there are more.

Really glad it arrived quickly.

I hope why it took so long to get ready and printed has become clearer...haha

If at all possible please try to read it like you would a novel, i.e. dont skip forward. Its written in such a way that many things later on
will not make much sense if you happen to skip pages earlier. Sadly, this does as you say mean that its a bit of a norse-saga to absorb.

Its not the sort of book where you find the image of the plane you like and read all the adjacent text then put it away confident you`ve learned what you were interested in.

I'm glad to read that bit. All too often people do just that and then go off half-cocked as they haven't read the related stuff elsewhere. That can be a tad irksome.
