Abstract: A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

Abstract: Disclosed herein is a system and method for effector reboot on an electric aircraft during flight. An effector controller may perform a power on built-in test on boot. An effector controller may selective perform an additional built-in test (ABIT) on boot based on instructions from a flight controller. The flight controller may use flags to indicate the necessity of an ABIT on boot. The effector controller may not perform an ABIT during flight. A backup controller may be used to send standard commands to an effector controller but may not sent an ABIT command.
