Abstract

A short term, autonomous, electrical power supply system, particularly an emergency short term, autonomous, electrical power supply system. Said system comprises an actuator with an electrical motor ( 14 ), an electrical generator ( 15 ) for driving said electrical motor ( 14 ) of said actuator, a turbine ( 13 ) in driving engagement with said electrical generator ( 15 ), an generator ( 7 ) of combustible, fluidic energy, a fluid line ( 10 ) from said generator ( 7 ) to said turbine ( 13 ), a control unit ( 5 ), and an igniter ( 9 ) arranged inside said generator ( 7 ) and controlled by said control unit ( 5 ).

First claim

What is claimed is:

1. An emergency short term, autonomous, electrical power supply system, the system comprising:
an emergency actuator with an electrical motor;
an electrical generator for driving the electrical motor of the emergency actuator;
a turbine in driving engagement with the electrical generator;
a gas generator of combustible, fluidic energy and/or gas generating chemicals;
a fluid line from the gas generator to the turbine;
an emergency control unit; and
an igniter arranged inside the gas generator and controlled by the emergency control unit;
wherein the emergency actuator is linked to a door via a support arm.

2. The system according to claim 1 , wherein the turbine is integrated in the electrical generator.

3. The system according to claim 1 , wherein a turbine adaptor or extension is provided and in that the turbine is mounted directly coaxial on the electrical generator by means of the turbine adaptor or extension.

4. The system according to claim 1 , wherein the energy is obtained from fluidic gaseous combustible.

5. The system according to claim 1 , wherein the gas generator is a plug type gas generator cartridge.

6. The system according to claim 1 , wherein the fluid line from the gas generator to the turbine comprises control means.

7. The system according to claim 1 , wherein the igniter is electro-explosive, electrically actuated by the emergency control unit.

8. The system according to claim 1 , wherein the igniter is inserted replaceable in a wall of an expansion chamber.

9. The system according to claim 1 , wherein the igniter is inserted replaceable in a wall of a separate chamber containing gas generating chemicals, the separate chamber being located in an expansion chamber.

10. The system according to claim 1 , wherein an electrical connection is provided and in that the electrical motor of the actuator is supplied from the electrical generator via the electrical connection.

11. The system according to claim 8 , wherein an electrical buffer is provided and in that the electrical motor of the actuator is supplied from the electrical generator via the electrical buffer by means of an electrical connection.

12. The system according to claim 1 , wherein the electrical motor and the electrical generator are in one housing.

13. The system according to claim 1 , wherein in that the emergency actuator allows manual door operation.

14. The system according to claim 1 , wherein an end position switch is provided for the emergency actuator.

15. The system according to claim 1 , wherein the emergency actuator is linked to an emergency exit door of an aircraft via a support arm.

16. The system according to claim 1 , wherein a turbine adaptor or extension is provided, with the turbine being mounted directly coaxial on the electrical generator via the turbine adaptor or extension.

17. A short term, autonomous, electrical power supply system, the system comprising:
an actuator with an electrical motor;
an electrical generator capable of driving the electrical motor of the actuator;
a turbine in driving engagement with the electrical generator;
a gas generator;
a fluid line connecting the gas generator to the turbine;
a control unit; and
a gas generator initiator arranged inside the gas generator and controllable by the control unit;
wherein the actuator is linked to a door via a support arm.

18. The system according to claim 17 , wherein the gas generator contains fluid or gas forming materials.

19. The system according to claim 17 , wherein the emergency actuator is linked to an emergency exit door of an aircraft via a support arm.

20. The system according to claim 17 , wherein the turbine is integrated in the electrical generator.
