Method and device for generating a flight plan for a tactical flight of an aircraft

Abstract: A flight plan for a tactical flight of an aircraft is generated using first input data including initial weight and initial loading of the aircraft, meteorological data, points of transit of the flight plan and at least one optimization criterion. With the aid of the input data and by implementing a prediction function and an optimization function, a flight profile of the flight plan is determined. The profile includes for each point of transit of the flight plan, a plurality of predictive information items and, between two successive points of transit of the flight plan, optimized parameters. The flight plan is presented on a display screen. A second input allows an operator to enter, for each tactical event of the tactical flight, a variation of at least one parameter which is modified by this tactical event at a particular point of variation of the flight plan. The flight profile is determined using each parameter variation which is taken into account at the corresponding point of variation.

Locking mechanism for latching a cargo piece to a loading floor

Abstract: A locking mechanism for latching cargo pieces to a loading floor of aircraft has two latches housed in a common latch housing. The latching claws face in opposite directions. The latches rotate on journal shafts arranged parallel to the longitudinal axis of the aircraft with a lateral on-center spacing between the journal shafts. Tension springs act eccentrically to hold the latches in their extended locking position. In the locking position the latches support each other by bearing against respective stops. An inclined ramp, provided on each latch and extending in the loading direcion, cooperates with a connecting lever joint to assure that the latches can be rolled over by cargo pieces of full width, while pieces of half the full width are arrested in lateral and vertical directions when the mechanism is located between two pieces of half width closely spaced from each other.

Model Deformation Measurement (MDM) at Onera

Abstract: [] Model Deformation Measurement is becoming a major topic in wind tunnel testing, especially for commercial applications. Onera has developed a solution which is used in several wind tunnels. The system uses two cameras in stereoscopic arrangement and the model shape is measured with markers. The main steps are: camera calibration, initial shape recognition, alignment of the calibration body reference system on the model reference system, wind tunnel testing and post processing. The wing twist uncertainty is lower than 0.05° which is the main requirement. The system can work at is best in real time conditions and can be easily adapted to each test section.

Method for avoiding air pockets in a joint between two structural components

Abstract: When two structural components are to be joined, for example, when an aircraft skin section is to be secured to a stringer by an adhesive bonding, it is important that the joining surface areas are plane to avoid the formation of air inclusions in the joint because air inclusions weaken the mechanical strength of the joint. Thus, a surface topography that is not plane must be smoothed out prior to the joining. For this purpose the surface areas to be joined are optically scanned to provide topographical information for each surface area that needs to be smoothed out for providing a plane joining surface. The topographical information is processed to ascertain the configuration and volume of the surface topography that needs to be filled with a filler material to produce a plane surface or at least a smooth surface without hills and dales. A respective control signal is produced and fed to a dosing equipment which supplies the exact volume of filler material required for planing or smoothing the surface topography. When smoothing is completed the two components are ready for joining for example by the application of pressure and heat to the filler material.

In-flight catering system - uses conveyors and circulating closed conveyors to move trolleys around aircraft interior

Abstract: The arrangement has containers (7) for trolleys (6) and a circulating closed conveyor system for moving them between upper and lower decks The conveyor system comprises elements (8) located on both sides of the container (2) and may be in the form of toothed belts, chains, rollers or roller bands The elements of the conveyor system can be arranged horizontally as well as vertically A facility (9) is provided for stowing and withdrawing the trolleys (6) USE/ADVANTAGE - In-flight catering for aircraft A large number of trolleys can be used without taking up much space
