Book cover for Spitfire Mk I and Bf 109 E during BoB 440 page ver 12 flattened small.jpg


Without exaggeration, there are probably hundreds of books that already diligently detail the history of the Spitfire Mk I and the Bf 109 E during the Battle of Britain time period. So isn't this just adding another one to the pile?

Well no, because this book is rather different: And while other books may faithfully cover the origins, the development, the different versions, the operational usage and the pilots who flew them, when it comes to these aircraft's performance the results are usually rather meagre.

And detailed performance analysis is what's new and what this book brings to the table: Because it's the first to compare these two iconic fighter utilizing verified and validated computer simulations to gauge how they truly compared, and not just repeating the same old performance numbers that have already been quoted, copied and pasted in between so many other books.

In addition, the entire performance envelope is investigated: So not just speed and climb, but also acceleration, sustained and instantaneous turn, dive, and dive and zoom performance. And this analysis has actually uncovered some previously hidden aspects of these aircraft: Not in the least concerning their turn performance, which is an area that has previously been considered to be a no contest win for the Spitfire. But as the simulations show, there are exceptions to this rule, especially if the Bf 109 drops some flap. And while the Spitfire certainly was the better turning aircraft overall, the difference was in some cases not as large as common knowledge would have us believe.

The book also covers some hypothetical scenarios: What would be the effect of reducing the Spitfire Mk I's big wing to one that instead was about the same size as on the Bf 109? Would this have made the Spitfire better or worse? Then looking at the Bf 109 E: If it instead of its low pressure aluminium radiator is equipped with a high pressure radiator cooling system like the one on the Spitfire, how much better performance would that have given it?

In summary, this book digs deeper into these aircraft's flight performance than any previous book has ever done, introducing for example acceleration, energy retention, sustained and instantaneous turn comparisons, dive, dive and zoom comparisons all in an attempt to determine just how close or far apart or close together they were regarding each particular performance aspect. In addition, the issue of the Bf 109 E's range is also analysed in greater detail than is usual in many other books, revealing that it may not have been quite as limited as it's often made out to be. And last, but not least, in the summary and conclusions, looks into if an overall winner can be crowned.

Added to this, the book also covers background information regarding the state-of-the-art at the time in aeronautics, aircraft procurement, specifications, aerodynamics, wing design, engine and propeller technology, radiator design, armament, production costs and more.

The book is 405 pages long, and contains circa 140 figures, chart and diagrams and about 100 pictures, and is available as a paperback on Amazon:

WW2 Fighter Performance volume 1: Design, Aerodynamics and Flight Performance for the Spitfire Mk I & Bf 109 E, Battle of Britain Era, by Anders F Jonsson, ISBN 978-91-987748-1-8.

Planned in the book- budget for next month.
I know you for years (like 20?!? ) through the il-2 forums, and know how you work.
Will be glad to read your book (and analyse all the graphs, love that stuff )
Next one Fw-190 vs spit9 ???:twisted:


This month the book budget went for the JG-2 Volume4 (last piece in stock, was little bit more pricy than other volumes) by Eric Mombeek. sorry...

Thank you for those kind words and I hope you will like it! And don't hesitate to contact me here or via the contact form on my homepage if you have any questions about the contents once you've had a chance to read a bit in it.

About the next installment: As it is now I'm treating myself to a vacation: I spent all of two months being my own editor working on the book's general layout and disposition, and to try to minimize spelling errors and bad grammar so I need a break for now.

Then about being my own editor: I actually made an active choice to self-publish: Following my first book, I've had offers from legacy publishers about this book, but TBH, none of them have been able to convince me that legacy publishing is the way to go these days, so unless I get some new better offer, I will continue on this road and try to get traction on my own.

Then about the next title: I was actually leaning more towards P-51 versus Fw 190/Ta 152 in the Battle of the Reich era, but if I get good arguments to go in another direction, I'm willing to listen to those. ;)

I won't hesitate to contact, know where to find you...(stalker's laugh :twisted:)
You're totally right about taking a break, nothing like some nice free time to clear your mind and get fresh ideas.

I'm actually very intrigued by the amazon print quality, this is gonna be the first KDP book in my collection, so i'll be able to see the result by myself (as i also have a long term book project i'm working on).
After having checked the average %pay per book sold using a legacy publisher, men get someting like 1.5/2€ max for such a book, this is peanuts, as this is a very niche domain, you're not gonna sell hundreds thousends of them, at least with KDP you got like 6/7€ and with few sales you can cover your ISBN nbr purchase, your "writer" test prints, etc... and you can put some bread on the table. If amazon can provide a good print quality, then the legacy publishers have a serious competitor.

If you do the battle of the reich, yes, Poney-D vs D-9 should be the way to go.(i wouldn't go with the ta152, or maybe just as a third data set to compare, but not in details. Too few of them beeing build, too few missions done.)

My experience with Kindle so far has been good: Both when it comes to clearing new editions for publishing and handling problems.

However, what you need to keep in mind when going via Kindle is that the book is printed close to the customer. This means different printers, and potentially differences in print and paper quality.

As an example, one US copy had what I would call poor paper quality and the print was more grayish than black. However, Kindle immediately refunded that book and promised to get in touch with the printer. Books printed in Germany (the only ones I've seen myself so far) have been quite good: White good quality paper and crisp clear black printing.

Covers have been very good and in line with paperback books I've received from Cambridge University Press for high end technical books. Speaking of CUP and paper and print quality, my Kindle book from Germany actually had better paper quality and the print was blacker.

In addition: Printing faults are not limited to Kindle: My first copy of A History of Aerodynamics by John D Anderson (terrific book BTW) had pages that fell out of it. I did get a new copy so no problem with that, but the lesson from this story is that even prestigious printers like Cambridge University Press can send out defective products.

Another customer of my WW1 book got a copy with stripes in some photos. But all these occurrences seem to be rare, and so far Amazon have been quick to rectify any problems and send out new copies ASAP so I can definitely recommend them over Lulu.

So, currently I see no downsides to go via Kindle and say go for it, especially if your book project is more niche like mine. Then your pool of potential customers frequent aviation forums anyway, so you can reach them there. For example, I got good traction in the Secret Projects Forum, and saw a worldwide spike in sales from posting there.

Thanks for the explanation.
Searched a little bit on the web with experiences of the buyers and the writers, and it seems, like you wrote, that all depends on the place where the book is printed.
i've read some nasty stuff from usa, about one of the Printers, where the quality was worse than an home inkjet printer.
Are you sure yours was printed in germany? i've read that all "european" books were now printed in Poland. there were dicsussions there from a year or 2 ago , so maybe that changed meanwhile.. anyway if the print is good, who cares where it's pritned:razz:
