User:Mr swordfish/List of works with the equal transit-time fallacy

This is a partial list of works with the equal transit-time fallacy presented as truth. The equal transit-time fallacy is a common misconception of how a wing creates lift. The misconception is based on the fallacy of an equality constraint on the transit times of air parcels traveling above and below a cambered airfoil, i.e. that the air traveling over the top of a wing must traverse the wing in the same amount of time as the air traveling under the wing.

There is no physical principle that requires the air to traverse the wing in the same amount of time, and experimental results show that this assumption is false. Although the Kutta condition requires the upper and lower surface velocities to be equal at the trailing edge, circulation associated with lift requires the transit times to be different, with the parcel on the longer route arriving earlier. The transit time is equal only in the special case where the airfoil is producing no lift.

Although currently accepted theories of aerodynamic lift were developed as early as 1907, the incorrect equal transit time fallacy became popularized later, especially after World War II. Despite the obvious problems with this "theory" in relation to lift of flat plates, symmetric airfoils, inverted flight, or sails, this incorrect explanation is often repeated, even in recent works, and in otherwise reliable sources.
