Zone Theory of Aerodynamic Lift in Action in Real World

August 28, 2024 | tekemon

ery few people study aerodynamics but everyone is interested in how airplanes and birds fly. We all want to know just what force lifts them up from ground and keeps them in air. The Zone Theory of Lift has finally solved the mystery of how wings generate lift force. What you are about to witness are the origins of Aerodynamic Airfoil Lift in actual real world flight conditions as stipulated by the zone theory; not any experimental wind tunnel or CFD (computational fluid dynamics) simulation. There's plenty of more scientifically correct info on the website on the origins of lift and airfoil functions, including an ebook. Only the Zone Theory of Lift provides detailed scientifically correct analysis of how the airfoil generates lift force by creating induction and subduction zones, of which lift is a natural by-product of this airfoil function. The Zone phenomenon seen here cannot be described by any existing hypothesis till now, even after 100 years of first flight by Wright Brothers or millions of years of bird flight. This Zone phenomenon cannot be replicated in any Wind Tunnel Experiment nor any CFD (Computational Fluid Dynamics) Simulation. Keep checking this channel as we will be adding exciting and iconoclastic new content, which will shatter all the existing vague and misleading explanations of lift force.

Discover the groundbreaking Zone Theory of Lift, which unveils the true mechanics behind how wings generate lift in real-world flight conditions. Unlike traditional theories that rely on outdated wind tunnel experiments, this innovative approach reveals the induction and subduction zones that create lift as a natural by-product. Witness the stunning visual evidence in our video, showcasing the condensation patterns over wings and the unique vortex paths. Join us as we challenge conventional wisdom and explore the fascinating science of aerodynamic lift that has eluded understanding for over a century. Don’t miss out on this revolutionary perspective!

Nacelle Strake Vortices Never Go Under the Wings … Why ?

September 12, 2023 | tekemon

In our last post on nacelle strake vortices, the Zone Theory of Lift was proven beyond any doubts, as the vortices showed the existence of the pressure zones. In this post we analyze the curious behaviour of these strake vortices, and the path they take over the wing after formation at the nacelle strakes of […]

Nacelle Strake Vortices – The Irrefutable Proof of Zone Theory of Lift

August 15, 2023 | tekemon

Nacelle Strake Vortices – The Irrefutable Proof of Zone Theory of Lift. Nacelle strakes are located on the front cowlings or nacelles of all modern jet engines, and create vortices that become visible in favourable atmospheric conditions. The paths of these nacelle strake vortices flawlessly give away the physical form of the pressure zones (Fig-3 […]

Zone Theory Explanation of Stall

October 28, 2024 | tekemon

Sequence of Events & Conditions Leading to Stall: 1. As AoA increases the lifter becomes the deflector. 2. The high pressure subduction zone (red) shifts from front to the bottom of wing. 3. Air from bottom of wing bleeds around the trailing edge to the top of wing. 4. The air leakage from bottom to top shrinks the induction zone (blue) reducing Lift. 5. At critical AoA, sufficent air leaks to the top reducing vacuum or lift and stall occours.

CAUTION: Angle of Attack is conducive to conditions which initiate stall! Increasing angle of attack eventually results in a complete stall. As everything else, the zone theory explanation of stall is simple and straight forward. Zone theory explains stall in simplest of terms i.e. of pressure leakage. Needlessly complicated reasoning is employed by the wind […]

Airfoils & Loudspeakers have a lot in common

October 10, 2024 | tekemon

Airfoils and Loudspeakers seem entirely unrelated but surprisingly, their mode of function has a lot in common.

Airfoils & Loudspeakers have lot in common though seemingly they are entirely unrelated. Surprisingly their mode of function is much similar, as you will learn from the following explanation. There are many ways to describe lift, as has been done in previous posts, and its apparent that no complicated concepts or calculations are required that […]

Are wind tunnels really the best way to understand aerodynamic lift? Discover why they might be the wrong tool for the job! The fascinating case of Howard Hughes’ Spruce Goose H-4 reveals the critical importance of reaching a specific speed, V1, before any lift can be generated. This excerpt dives into the limitations of traditional methods like wind tunnels and CFD simulations, and introduces the groundbreaking Zone Theory that explains how the Wright Brothers unlocked the secrets of efficient lift generation. Join us as we explore the true nature of lift and its implications for aviation!

Bi Planes of Early Flying Days

August 6, 2024 | tekemon

Airfoil dimensions and proportions. The deflector, inductor, lifter dimensions and angle alpha determine the suitability of airfoil for a given airspeed range.

We focus our discussion on the bi-planes of the early flying days, which always had more then one wing by default, to achieve the required lift. Some of them can be seen in images below. The question is why use two or even three wings ? The usual explanation given for this type of double […]

Airfoil-Most Efficient Aerodynamic Form – Persu Car of 1922

July 21, 2024 | tekemon

A car design of 1922 has still proven today that the airfoil is the most efficient aerodynamic form or shape for an object which travels through air and inevitably encounters air resistance, be it an aircraft or in this case, an automobile. The car called a Persu, was designed by a Romanian engineer Aurel Persu. […]

Zone Theory Explains the Ground Effect

June 10, 2024 | tekemon

The zone theory explains the ground effect flawlessly, and proved its correctness by accurately describing how this effect is created during landing or takeoff. Ground effect refers to a slight increase in lift when an aircraft is close to the ground at an altitude comparable to its wingspan. As usual, all sorts of wrong theories […]

Flat Earthers and Streamliners

September 13, 2023 | tekemon

Flat Earthers and Streamliners are not very different. It is strange what makes aerodynamicists believe that the atmosphere has a constant flow of these streamlines which interact with aircraft and make it fly. If the plane makes a U-turn, will these streamlines also start flowing backwards ? There are specific air corridors as per aviation […]

Einstein Failed using Bernoulli’s Principle for Wing Design

September 8, 2023 | tekemon

It came nothing less then a sheer surprise, rather bit of a shock, that even Einstein had absolutely not even the slightest understanding of airfoil lift force.

Einstein Failed using Bernoulli’s Principle for Wing Design ?… hard to believe, but its true. Its certainly not an over-statement to say that the reason why mystery of lift remained unsolved for more then a century, is due solely, to the collective failure of the scientists, both past and present. It came as nothing less […]

Flying Fish – Once again, no V1, no Lift

September 7, 2023 | tekemon

Are flying fish nature’s oddity or a statement ? Once again another convincing proof of the Zone Theory of Lift comes from nature itself. This time from flying fish and how they do it. The flying performance of the flying fish is shown in images below, and what’s even more impressive is that they get […]

Why Bernoulli and Newton Failed to Lift

August 30, 2023 | tekemon

In the course of last century and even today, aerodynamics “experts” take pride in revolving around scientific principles of Bernoulli and Newton as they explain how lift is produced by the airfoil. Einstein designed a wing, which failed disastrously, due to a lack of insight into airfoil behavior. Einstein used Bernoulli’s principle so failure was […]

Everything you were told about how aircraft fly is Wrong !

February 25, 2023 | tekemon

Throw away your text books and stop watching misleading Youtube videos on how lift is generated by an airfoil. Everything you were told about how aircraft fly is Wrong! As much as it’s talked about in terms of mathematics and engineering, to make it look like so; Aerodynamics is not at all a science, It’s […]
