This is the first book to comprehensively cover WW1 fighter aircraft focusing on their relative flight performance utilizing modern computer simulations and if you want to get a better understanding of how they compared to each other, then this is the book for you. Based on the simulation results, a number of myths surrounding the modeled aircraft can be put to rest and in addition, they reveal some unexpected results that go against the grain of what has become generally accepted facts about these airplanes. While anecdotal evidence runs the risk of misremembering and embellishments, hard numbers based on computer simulations are more neutral and allow a more complete picture of these aircraft to emerge revealing their true strengths and weaknesses. Another first is the detailed analysis of how the aircraft compare in terms of acceleration, dive, and sustained and instantaneous turn performance done to a level previously not attempted in a book. The aircraft covered in this book are the Albatros D.Va, Fokker Dr.I, Fokker D.VIIF, Fokker E.V, Fokker D.VIII, Nieuport 28.C1, Pfalz D.III, Pfalz D.IIIa, Pfalz D.VIII, Siemens Schukert D.IV, Sopwith, Sopwith Triplane, S.E.5a and SPAD XIII. As a background to the analysis of the results and the rationale for how the aircraft were modeled, the book also contains a brief summary of the state of the art in aerodynamics and aircraft design at the time.
