Abstract

A system for automatic optimization of an ejection system for an aircraft includes the ejection system having a plurality of adjustable settings. The system further includes a sensor configured to detect weight data corresponding to a weight of a user of the ejection system. The system further includes a controller coupled to the ejection system and to the sensor and configured to adjust at least one of the plurality of the adjustable settings of the ejection system based on the weight data.

First claim

What is claimed is:

1. A system for automatic adjustment of an ejection system for an aircraft, the system comprising:
the ejection system having a plurality of adjustable settings;
a seat having a bucket portion;
a sensor, wherein the sensor includes at least one pressure sensor coupled to the bucket portion and configured to detect a pressure applied to the bucket portion of the seat; and
a controller coupled to the ejection system and to the sensor and configured to:
determine weight data based on the detected pressure; and
adjust at least one of the plurality of the adjustable settings of the ejection system based on the weight data.

2. The system of claim 1 , wherein the controller is further configured to:
control an actuator configured to exert a force to adjust a height of the bucket portion.

3. The system of claim 2 , wherein the weight data includes an amount of force required to cause the height of the bucket portion to remain unchanged.

4. The system of claim 3 , wherein the controller is further configured to calculate the weight of the user based on the amount of force required to cause the height of the bucket portion to remain unchanged.

5. The system of claim 4 , wherein the controller is further configured to compensate for a current temperature in response to calculating the weight of the user.

6. The system of claim 4 , further comprising an input device configured to receive a desired adjustment to the height of the bucket portion, wherein the controller is configured to select the amount of force at a time at which the height of the bucket portion remains unchanged during an adjusting process of the height of the bucket portion.

7. The system of claim 1 , wherein the ejection system includes a seat electronic sequencer and the plurality of the adjustable settings include at least one of a parachute deployment timing, a drogue deployment timing, or a thrust angle alignment.

8. The system of claim 1 , wherein the ejection system includes an interseat electronic sequencer and the plurality of the adjustable settings include an interseat timing.

9. A system for automatic adjustment of an ejection system for an aircraft, the system comprising:
the ejection system having a plurality of adjustable settings;
a seat having a bucket portion in which a user of the ejection system rests;
a sensor coupled to the seat and, wherein the sensor includes at least one pressure sensor coupled to the bucket portion and configured to detect a pressure applied to the bucket portion of the seat; and
a controller coupled to the ejection system and to the sensor and configured to:
determine weight data based on the detected pressure; and
adjust at least one of the plurality of the adjustable settings of the ejection system based on the weight data.

10. The system of claim 9 , wherein the controller is further configured to:
control an actuator to exert a force to adjust a height of the bucket portion, wherein the weight data includes an amount of force required to cause the height of the bucket portion to remain unchanged.

11. The system of claim 10 , wherein the controller is further configured to calculate the weight of the user based on the amount of force required to cause the height of the bucket portion to remain unchanged, and wherein the controller is further configured to compensate for a current temperature in response to calculating the weight of the user.

12. A method for automatic adjustment of an ejection system of an aircraft, the method comprising:
detecting, by a sensor, a pressure applied a the bucket portion of a seat of the ejection system, wherein the sensor is a pressure sensor;
determine, by a controller, weight data based on the detected pressure; and
adjusting, by the controller, at least one of a plurality of adjustable settings of the ejection system based on the weight data.

13. The method of claim 12 , wherein the method further comprises:
controlling, by the controller, an actuator to exert a force to adjust a height of a bucket portion of a seat based on the weight data.

14. The method of claim 13 , wherein detecting the weight data includes detecting an amount of force required to cause the height of the bucket portion to remain unchanged.

15. The method of claim 14 , further comprising calculating, by the controller, the weight of the user based on the amount of the force required to cause the height of the bucket portion to remain unchanged.

16. The method of claim 15 , wherein calculating the weight of the user further includes compensating for a current temperature of the actuator.

17. The method of claim 15 , further comprising receiving, by an input device, a desired adjustment to the height of the bucket portion, wherein calculating the weight of the user includes selecting the amount of force at a time at which the height of the bucket portion remains unchanged during an adjusting process of the height of the bucket portion.
