The invention relates to an air-conditioning system for an aircraft cabin () comprising: an engine air bleed device (); an air-conditioning pack () comprising a pack air inlet () connected to said engine bleed device (), and a pack air outlet () connected to said cabin (); an auxiliary module () for supplying pressurized air comprising an auxiliary turbomachine (), comprising a compressor () supplied with external fresh air and a turbine suitable to be able to be supplied with air coming from the engine bleed device; and a control unit configured to activate either a standard mode in which the pack air inlet is supplied with the pressurized air coming from the engine bleed device (), or a fresh air mode in which said pack air inlet () is supplied with the pressurized air coming from the auxiliary module ().

Module for supplying pressurized fresh air to an air-conditioning pack of an aircraft cabin, air-conditioning system equipped with such a module, and corresponding method

The invention relates to an air conditioning system for a cabin () of an aircraft () comprising: a bleed air source (); a ram-air circulation channel (); a network of pipes and control valves; an air cycle turbine engine comprising at least one compressor () and a power turbine () which are mechanically connected to one another; and at least one primary cooling exchanger (PHX) which is accommodated in said channel (), characterized in that said pipe network comprises a thermal power pipe () which is suitable for being able to fluidically connect, upon control of at least one control valve (), said air outlet () of said power turbine () and said ram-air circulation channel () upstream of said primary exchanger (PHX) so that said bleed air expanded by said power turbine () can form a thermal energy source for said ram air being supplied to said primary circuit of said primary exchanger (PHX).

Air conditioning system for a cabin of an air or rail transport vehicle using a pneumatic and thermal air source which is separate from the air conditioning source

The invention relates to an electrical air conditioning system for air conditioning a cabin () of an aircraft comprising a source () of fresh air, a dynamic air circulation duct (), a motorized compressor () comprising an air inlet connected to said source of fresh air, and an air outlet connected to a primary cooling exchanger (PHx) housed in said dynamic air duct; an air cycle turbomachine () comprising at least a first compressor () and a first turbine () that are mechanically coupled to one another, said first compressor comprising an air inlet that can be connected either to said primary cooling exchanger (PHx) or to said source () of fresh air, and an air outlet connected to a main cooling exchanger (MHx) housed in said dynamic air duct, said first turbine () comprising an air inlet that can be connected either to a discharge port () for discharging stale air from said cabin or to said main cooling exchanger (MHx), and an air outlet that can be connected either to said cabin () or to an air injector () opening into said dynamic air duct.

Systems and methods for communicating avionic data to a non-avionic device situated outside of the cockpit of an aircraft are provided. A method may comprise the steps of receiving a request, aimed at receiving avionic data from avionic systems, from a non-avionic client device; determining the distance between the non-avionic device and the cockpit of the aircraft; and adjusting the sending of data in response to the request depending on the determined distance. Developments of the invention describe the use of a wireless access point associated with a secure gateway determining the access rights to the avionic data for the non-avionic device, various sending and/or display adjustments depending notably on the distance, threshold management, various indoor positioning techniques, unilateral or bilateral communications, various notifications, the use of lightweight connected clients (for example earpiece, watch, glasses, etc.).

Continuity of access to avionic data outside of the cockpit of an aircraft

Disclosed is a method for ventilating a ram air channel for a vehicle&#x2014;in particular an aircraft&#x2014;including at least one heat exchanger. The ram air channel is provided with a jet pump including a plurality of compressed air inlets connected to a plurality of separate compressed air sources of the vehicle, and a plurality of compressed air outlet nozzles. At least two nozzles are independently connected to at least two separate compressed air sources of the vehicle.

Method for ventilating a ram air channel and environmental control device and vehicle implementing this method

A method implemented by computer in or for a flight management system or FMS, comprises the steps of receiving requests issued by clients; determining a correspondence between the requests and predefined unitary services executable by at least one server associated with the FMS; queuing the unitary services determined in one or more queues; determining a response time associated with each request; and notifying at least one client of the response time to its request. Developments describe the processing of queues, the management of priorities, the existence of fixed-price contracts, caching mechanisms, interruptions of queues, cancellations of requests, voting mechanisms, etc. The unitary services in particular can be avionics services of ATA (Air Transport Association) type. Systems aspects and software aspects are described.

Quality of service of a flight management system

The system executes services by an application called 'server' for at least one application called 'client.' A preliminary step establishes for each service a list of calculation parameters that can be varied in a given range, called &#x201c;adjustable parameters&#x201d; as well as time and quality of the said service information according to the value of the said parameters. At the request of a client for a given service, the method adjusts the value of the adjustable calculation parameters as a function of a given constraint, the service being executed using the adjusted values of the said parameters.

Adaptive method for the execution of services in real time, notably of flight management and real time system using such a method

A system executes services by a 'server' for a 'client'. A preliminary step establishes a list of available services of the server, set up for the client, in which a processing time is determined releasable by the server for the client per code execution cycle minor frame (&#x201c;MIF&#x201d;). The system creates on start-up: NT execution tasks for the client, each having a priority of execution level and an allocated average duration of execution, a number of execution tasks (NT) being at least 1, the sum of durations of the tasks being at most the releasable processing time; execution rules associating each of the tasks with at least one service of the list; then, during each MIF cycle, the system executes the services on their associated tasks, a task executed by priority and for at most its allocated average time of execution, the non-executed part of a service being executed on its associated task in the next cycle.
