Abstract
A sequencer system for an ejection assembly may comprise a first A-side controller and a second A-side controller in operable communication with the first A-side controller. A first B-side controller may be in operable communication with the first A-side controller. A second B-side controller may be in operable communication with the first B-side controller and the second A-side controller. The controllers may be configured to each make an initial ejection sequence determination and a verified ejection sequence determination. The controllers may make the verified ejection seat determination based on a two of three voting scheme.
Claims20
A sequencer system for an ejection assembly, the sequencer system comprising:
- a first A-side controller configured to determine a first initial ejection sequence and a first verified ejection sequence;
- a second A-side controller configured to determine a second initial ejection sequence and a second verified ejection sequence;
- a first B-side controller configured to determine a third initial ejection sequence and a third verified ejection sequence;
- and
- a second B-side controller configured to determine a fourth initial ejection sequence and a fourth verified ejection sequence, wherein:
- the first A-side controller is configured to determine the first verified ejection sequence based on a comparison of the first initial ejection sequence to the second initial ejection sequence and the third initial ejection sequence,
- the second A-side controller is configured to determine the second verified ejection sequence based on a comparison of the second initial ejection sequence to the first initial ejection sequence and the fourth initial ejection sequence,
- the first B-side controller is configured to determine the third verified ejection sequence based on a comparison of the third initial ejection sequence to the first initial ejection sequence and the fourth initial ejection sequence, and
- the second B-side controller is configured to determine the fourth verified ejection sequence based on a comparison of the fourth initial ejection sequence to the third initial ejection sequence and the second initial ejection sequence.
