This patent has two additions within the French system. We have virtually no data on the first addition. While this parent patent features a pendulum, responsive to aircraft tilt, an element we have found before in the context of specifically automatic airplane stability, the second addition, Patent FR-1911-421257.14854, upon which we have good data, focuses on the specific application, to the ailerons. of the compressed air which is crucial throughout this patent family.
So, the tilt of the aircraft affects the pendulum, and the pendulum directs the compressed air, which in turn affects the specific movement of the ailerons, and the resulting affect on control and stability.
