摘要： A control box for selectively delivering orders to receivers (8, 12). The control box comprises a shaft (14) mounted to turn about an axis of rotation (X), while being capable of sliding along the axis (X) between a rest position towards which it is urged by return means (24), and an active position. An order delivery apparatus (16, 11) co-operates with the shaft (14) to deliver orders as a function of the angular position of the shaft (14). A rotary drive (15) causes the shaft to turn. A safety actuator (23) causes the shaft to slide from the rest position in which anti-rotation structure (27, 28) prevents the shaft from turning to the active position in which the anti-rotation structure (27, 28) leave the shaft free to turn under drive from the rotary drive (15).

摘要： A method and apparatus for air-ground detection. A truck beam of a semi-levered landing gear is mounted on a pivot pin. The truck beam is configured to rotate about the pivot pin between a toes down position and a toes up position. A positioning mechanism is connected to a semi-levered linkage assembly that secures an angle of the truck beam in the toes up position. The semi-levered linkage assembly is secured in a steady state and configured to change from the steady state to a locked state in response to an initial ground contact. A sensor is connected to the semi-levered linkage assembly. The sensor is configured to detect a change from the steady state to the locked state.

摘要： Method and system of determining ground-to-tyre friction coefficient for an aircraft landing event. The method uses an aircraft computational model to repeatedly model the landing event, varying one or more initial conditions of the aircraft model until a best match between a modelled value and a provided value of aircraft vertical acceleration is determined. The method uses initial conditions associated with the best match of modelled and provided vertical acceleration values and a strain value from a sensor on the aircraft landing gear, with the ground-to-tyre friction coefficient is a variable. The method models the landing gear to generate a modelled strain value and compares this with the measured strain value, and repeats the landing gear modelling step with a different value for the ground-to-tyre friction coefficient until a best match between the modelled strain value and the measured strain value is determined and outputting the respective friction coefficient value.

In this regard, a method is provided comprising receiving pulse information over a first time period, wherein the pulse information is indicative of an angular distance traveled by a first wheel, comparing the pulse information to a threshold value, and determining a likelihood of a landing event based upon the comparison. In various embodiments, a system is provided comprising a monstable multivibrator in electrical communication with a metal-oxide-semiconductor field-effect transistor (MOSFET), a resistor-capacitor network in electrical communication with the MOSFET, and a comparator that receives a voltage from the resistor-capacitor network and a reference voltage.
