Title: A METHOD FOR GENERATING LIFT AND A DEVICE FOR IMPLEMENTING THE METHOD
Abstract:
The object of the invention is a method for generating lift for an airborne flying device, which has a wing part and/or a fuselage part generating lift by means of interactive movement between the air and the device. In the method, in the frontal view area of the lift-generating part of the device is arranged at least one counterflow impulse surface (1), which is formed by a planar or curved surface extending forward in the direction of travel from the lower surface (2) of the wing and/or fuselage and obliquely upwards, and which generates at least the main part of the lift when the airflow hits this inclined impulse surface and bends when the device is airborne.
