Methods and systems for transmitting data from an aircraft engine. A plurality of input signals are received at a control device, during an operation of the aircraft engine, from one or more sensors of the aircraft engine, one or more actuators of the aircraft engine, or any combination of the one or more sensors and the one or more actuators. The plurality of input signals are combined, at the control device, into an output signal indicative of the operation of the aircraft engine. The output signal is transmitted, at the control device, to a controller located remotely from the aircraft engine.

An assistance method for assisting a pilot of a single-engined rotary-wing aircraft during a flight phase in autorotation, the aircraft including a hybrid power plant provided with a main engine, with an electric machine, with a main gearbox, and with an electrical energy storage device. The aircraft also includes a main rotor driven by the hybrid power plant. In the method, during a flight, operation of the main engine is monitored in order to detect a failure, in particular by means of a drop in power on the main rotor, then, when a failure of the main engine is detected, the electric machine is controlled to deliver auxiliary power We to the main rotor, making it possible to assist a pilot of the aircraft in performing the flight phase in autorotation following the failure.

Disclosed herein is a method of measuring a gap between exterior structures and interior structures. The method comprises directing a transmitted m-wave signal from an exterior surface of the exterior structure into the exterior structure and the interior structure. The transmitted m-wave signal is generated by a gap sensing device that comprises an electromagnetic dual-tuned resonant coil sensor. The method also comprises measuring a received m-wave signal with the gap sensing device. The received m-wave signal comprises the transmitted m-wave signal influenced by the assembly. The method further comprises determining a size of the gap between the exterior structure and the interior structure based at least partially on at least one measured characteristic of the received m-wave signal.

A disclosed airborne vehicle includes split-ring resonators (split ring resonators), which may be embedded within a material. Each split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. Each split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, each may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.
