The draft of the book The Secret of Flight is now under revision into completion for final publishing. Suggestions for publisher are welcome! The revised version will in particular include recent results presented at the High Lift Prediction Workshop III (see previous post) and new analysis of the critical phenomenon of stall: see movie.

# High Lift Prediction Workshop III

As one of 40 teams competing at High-Lift Prediction Workshop III, Hoffman-Jansson-Johnson showed for the first time computational simulation of full time-dependent turbulent flow around a jumbo-jet in full landing configuration, including the following unique features:

- automatic turbulence simulation
- automatic adaptive error control
- computational efficiency
- superb agreement with experiment including stall

as the overall best result. The flow simulator by HJJ opens the possibility of constructing a first real flight simulator based on the real physics of turbulent air flow. Such a simulator will open to new forms of realistic pilot training of e.g. take-off and landing of a jumbo-jet under severe wind conditions or machine failure.

This ground breaking work is presented here.

# New Theory of Flight Published in JMFM!

Our New Theory of Flight (together with Johan Hoffman and Johan Jansson) has now been published in Journal of Mathematical Fluid Mechanics (online behind paywall and free originally submitted (2012) preprint) .

New Theory of Flight springs from our resolution of d’Alembert’s paradox formulated in 1755, published in JMFM 2008, and shows for the first time that both simulation and understanding of the miracle of flight is possible with present computer and brain power. As such it has every chance of becoming a landmark article.

New Theory of Flight is published by JMFM with a special Editors Foreword inviting scientists, mathematicians and engineers to scrutiny and discussion.
