Abstract

A kit for manufacturing electronic aircraft control units having different specifications, the units including electronic modules of different types, including avionics platform modules comprising at least an electronic monitoring circuit and an electronic control circuit that are segregated from each other; first protection modules for protecting the avionics platform modules; first extended connection modules; and second protection modules for protecting the extended connection modules; the modules of each type being identical with one another.

First claim

The invention claimed is:

1. A kit for manufacturing electronic aircraft control units having different specifications, the units comprising electronic modules of different types, including:
avionics platform modules comprising at least an electronic monitoring circuit and an electronic control circuit that are segregated from each other, the avionics platform modules being identical with one another and being arranged:
to receive data signals from an inertial navigation system, from attitude and heading reference system, from sensors, from trim device, and from pieces of equipment including engine and landing gear;
to receive control signals from a pilot interface;
to respond to the received data signals by preparing the control signals that are to be transmitted to the trim device and to the pieces of equipment;
to monitor elements to which the elements are connected within the electronic control circuit; and
to transmit the data signals to the pilot interface;
first protection modules for protecting the avionics platform modules, the first protection modules being identical with one another;
first extended connection modules, the first extended connection modules being identical with one another; and
second protection modules for protecting the extended connection modules, the second protection modules being identical with one another.

2. The kit according to claim 1 , wherein each of the avionics platform modules incorporate an inertial measurement unit.

3. The kit according to claim 1 , wherein each of the avionics platform modules incorporate a common power supply circuit.

4. The kit according to claim 3 , wherein each of the avionics platform modules incorporate circuit portions each including an individual power supply circuit connected to the common power supply circuit and arranged to power at least one component of the circuit portion at a voltage that is different from a voltage supplied by the common power supply circuit.

5. The kit according to claim 1 , wherein each of the avionics platform modules comprise a motherboard provided with at least one mezzanine carrying electronic components.

6. The kit according to claim 5 , each of the avionics platform module includes a plurality of mezzanines among which the mezzanines include carrying tallest electronic components, the mezzanines carrying the tallest electronic components are arranged on a common side of the motherboard.

7. The kit according to claim 1 , wherein the electronic modules include trim modules for performing analog/digital conversion of signals exchanged between the avionics platform modules and an analog trim device.

8. The kit according to claim 1 , wherein the electronic modules include actuator control modules for performing analog/digital conversion of signals exchanged between the avionics platform modules and an analog actuator device.

9. The kit according to claim 1 , wherein the electronic modules include video acquisition modules and third basic protection modules for protecting the video acquisition modules.

10. The kit according to claim 1 , wherein the electronic modules include double first basic protection modules, each arranged to be capable of being connected to two of the avionics platform modules, and single first basic protection modules, each arranged to be capable of being connected to at least one of the avionics platform modules.

11. The kit according to claim 10 , wherein the electronic modules include additional protection modules for connecting to the double first or single first basic protection modules in order to adapt them to aircraft of composite structure.

12. The kit according to claim 1 , wherein the electronic modules include extended second connection modules, the extended second connection modules being of structure different from the first extended connection modules.

13. The kit according to claim 1 , wherein some of the electronic modules incorporate Ethernet interfaces that include an Advanced Ethernet Network type.

14. A kit for manufacturing electronic aircraft control units having different specifications, the units comprising electronic modules of different types, including:

first protection modules for protecting the avionics platform modules, the first protection modules being identical with one another;
first extended connection modules, the first extended connection modules being identical with one another; and
second protection modules for protecting the extended connection modules, the second protection modules being identical with one another.

15. A kit for manufacturing electronic aircraft control units having different specifications, the units comprising electronic modules of different types, including:
avionics platform modules comprising at least an electronic monitoring circuit and an electronic control circuit that are segregated from each other, the avionics platform modules being identical with one another;
first protection modules for protecting the avionics platform modules, the first protection modules being identical with one another;
first extended connection modules, the first extended connection modules being identical with one another;
second protection modules for protecting the extended connection modules, the second protection modules being identical with one another;
double first basic protection modules, each arranged to be capable of being connected to two avionics platform modules, the double first basic protection modules being identical with one another; and
single first basic protection modules, each arranged to be capable of being connected to an avionics platform module, the single first basic protection modules being identical with one another.
