There is provided an aircraft flight control system comprising: a computing arrangement including an input interface and an output interface; wherein in operation the computing arrangement executes instructions to provide indications related to an estimated atmospheric contamination risk to at least one aircraft at selected locations and altitudes or pressures, by (i) receiving at least one aircraft flight plan data from the input interface; wherein at least one aircraft flight plan data includes at least one of time, a pressure or an altitude, a trajectory and a location representing at least one aircraft flight; (ii) determining the estimated atmospheric contamination risk using a measure of the at least one atmospheric contaminant for the at least one aircraft flight based upon a location, an altitude or pressure, a trajectory and a time information extracted from the at least one aircraft flight plan data; and (iii) providing, via the output interface, a resultant indication related to the estimated atmospheric contamination risk to the at least one aircraft.

System and method for aircraft flight control

There is provided a flight trajectory system that estimates contaminant exposure experienced by a flight for scheduling of flight maintenance interventions, comprising: at least one input interface that receives at least one trajectory of a flight comprising flight track points; a storage medium containing executable instructions for executing a flight trajectory algorithm and a database of flight trajectory data; and a computing arrangement coupled to the at least one input interface and the storage medium, wherein the computing arrangement receives the at least one trajectory of the flight and interrogates the database of flight trajectory data to: validate the flight track points, wherein the flight track points are validated based on at least one performance of the flight, generate a fixed trajectory for the flight based on the validated flight track points and the flight trajectory algorithm, and analyze, using a flight trajectory model, the fixed trajectory of the flight to estimate contaminants exposure of the flight on the fixed trajectory for scheduling flight maintenance interventions, and wherein the contaminants comprise at least one of: dust, ice, atmospheric aerosol particles or corrosive gases.

System and method for generating an aircraft flight trajectory

The proposed vibrational energy harvester comprises a frame (), a mass () coupled to first and second primary flexures () which are configured to flex and allow the mass to move in a first direction (), a plurality of secondary flexures () which are configured to flex and allow the mass to move in a different second direction (), and a transduction assembly configured to convert movement of the mass and flexures into electrical energy, preferably of electrodynamic or piezoelectric type. Each of the primary flexures is coupled to a secondary flexure at a position spaced from the mass. The resonant frequency of torsional vibration modes can thereby be raised to a frequency higher than the frequency band of ambient vibrations, which effectively prevents the energy harvester from vibrating in undesirable torsional modes that would result in wear between components.

Vibrational energy harvesters with reduced wear

There is provided a vibrational energy harvester comprising: a frame, a flexure assembly coupled to the frame, the flexure assembly comprising a flexure configured to flex in a first direction relative to the frame and a mass fixed to the flexure, wherein when the mass is displaced in the first direction from a rest position, the flexure provides a restoring force on the mass to bring the mass back to the rest position, and a transduction assembly configured to convert movement of the mass and flexure into electrical energy, wherein the frame comprises a cavity positioned so that, if the mass is displaced in the first direction beyond a threshold distance, a portion of the flexure assembly extends into the cavity so that compression or restriction of fluid in the cavity applies an additional force on the flexure assembly.

There is disclosed an aircraft operation scheduling system, wherein:
