Combined gravitational potential for Earth–Moon system with Lagrange points. Motion under gravitation is according to the New View described by the following set of equations in terms of the gravitational potential and immaterial free fall trajectories ; , (mass conservation) , , […]

Schrödinger’s equation as the basic mathematical model of quantum mechanics of a system of interacting particles (electrons and kernels), is commonly motivated as an analog to a classical -body problem with classical momentum translated to the spatial gradient of a 3N-dimensional wave function depending on 3-dimensional space variables , with the dependence on supposed to describe […]

We show as part of the revelation of The Secret of Flight that slightly viscous bluff body flow, such as the flow around a wing, can be described as potential flow modified by 3d rotational separation with point stagnation. This makes slightly viscous bluff bod flow both computable and […]

England vs Germany during the 1s World War: Sopwith Camel vs Fokker DVII Scout Single Foreword to the book The Secret of Flight: I have not the smallest molecule of faith in aerial navigation other than ballooning or of expectation of good results from any of the trial we hear of. (Lord Kelvin refusing to join the […]

Kelvin’s Circulation Theorem states that the vorticity of incompressible inviscid flow is preserved in a fluid without exterior forcing (subject only to inertial and pressure forces). Kelvin’s Theorem is presented as a corner stone of the Kutta-Zhukovsky circulation theory of lift. The proof consists in taking the curl of the momentum equation of the incompressible […]

The text book theory describing the generation of lift by a wing is the Circulation Theory (CT) developed by Kutta-Zhukovsky more than 100 year ago. The New Theory of Flight shows that CT is unphysical and incorrect: Lift is not generated by large scale circulation around a wing section. There is no physical mechanism generating […]

The Enigma of the Aerofoil: Rival Theories in Aerodynamics 1909-1930, by David Bloor, 2011, describes the initial British criticism of the German circulation theory of lift developed by Kutta and Prandtl in the beginning of the 20th century, which resisted the attack in the absence of something better and became the leading theory propagated in […]

The standard aerodynamics text book Aerodynamics for Engineering Students, 5th edition, by Houghton and Carpenter informs the students in Chapter 4: By the end of the 19th century the theory of potential flow was extremely well developed. But for the most important practical applications in aerodynamics potential flow was almost a complete failure. Flow separation and […]

We read in the opening chapter of Early Developments of Modern Aerodynamics by Ackroyd, Axcell and Ruban: Our stress on viscosity will no doubt surprise newcomers to the subject. However, it must be emphasized at the outset that, without viscosity, all flight, even in nature, would be impossible since wings would produce no lift. From this it follows that […]

Listen to Euler describing his equations: Everything that the theory of fluids contains is embodied in the two equations I have formulated. It is not the laws of mechanics that we lack in order to pursue this research, only the analysis which has not been sufficiently developed for this purpose. We have to wait until the […]
