Abstract: In some examples, a cabin pressure control and monitoring system includes an outflow valve, a first motor configured to operate the outflow valve to release fluid from a cabin, and a second motor configured to operate the outflow valve to release fluid from the cabin. The cabin pressure control and monitoring system also includes a first microcontroller configured to automatically control the first motor based on a pressure of the fluid in the cabin. The cabin pressure control and monitoring system further includes a second microcontroller configured to control the second motor based on user input and monitor the pressure of the fluid in the cabin. In some examples, a type of the first microcontroller is different than a type of the second microcontroller.

Abstract: A distributed aircraft cabin pressure control system (CPCS), and techniques for interfacing the distributed CPCS to avionics. The CPCS-specific equipment of this disclosure is used in a variety of different type aircraft with no hardware or software change for each aircraft type. In this manner, CPCS-specific equipment is used in different type aircraft without the need for formal re-certification of the CPCS-specific equipment. The CPCS-specific equipment may operate with limited, and fixed, functionality and control algorithms in its hardware and software that would not change from airplane application to application, but it would instead use “gain terms” transmitted from the avionics. The distributed CPCS processes in the various avionics modules may send information to the CPCS-specific equipment that customizes the operation of the CPCS-specific equipment to that specific aircraft type.

Abstract: A high-integrity electromechanical actuator control system includes a system function controller, a plurality of actuator controllers, and at least one electromechanical actuator. Each actuator controller includes a primary channel having a first controller, a second controller, and a duty cycle computation circuit, and includes a backup channel having a backup controller. The first controller receives digital actuator control commands from two functional control channels and supplies first digital duty cycle commands. The second controller receives digital actuator control commands from two functional control channels and supplies second digital duty cycle commands. The duty cycle computation circuit computes an average of the first and second duty cycle commands and generates pulse width modulated (PWM) commutation control signals based on the computed average. The backup controller receives digital actuator control commands from two different functional control channels and generates and supplies backup PWM commutation control signals.

Abstract: The disclosure is directed to an independent manual control system of an all-electric cabin pressure control system (CPCS). The manual control system may include a momentary electrical switch to manually set the position of an outflow valve (OFV) along with a closed loop control to hold the cabin pressure at the pressure setpoint. The closed loop control of the manual control system is independent from the automatic pressure control functions of the all-electric CPCS.

Abstract: In some examples, a thrust recovery valve system is configured to use an outflow valve to discharge a fluid flow from a cabin of an aircraft to an external environment surrounding the aircraft. The outflow valve may include a frame supported by a body of the aircraft and a gate configured to displace from the frame to define a flow passage for the discharge of the fluid follow. The thrust recovery valve system includes an obstacle configured to extend into the fluid flow in an extended position and retract from the fluid flow in a retracted position. In examples, the obstacle is configured to extend from and/or retract into a wall surface defined by the frame.

Abstract: A digital surface position sensor includes a position sensor, an adaptable hardware interface, and a processing circuit. The position sensor is adapted to be coupled to an aircraft flight control surface and is configured to sense a position of the aircraft flight control surface and supply a position signal representative thereof. The adaptable hardware input supplies an identification signal that identifies the aircraft flight control surface to which the position sensor is coupled. The processing circuit is coupled to receive the position signal and the identification signal. The processing circuit is configured, upon receipt of the signals, to process the position signal and the identification signal and generate (i) a first digital position signal representative of the position of, and the identification of, the aircraft flight control surface and (ii) and independent second digital signal representative of the position of, and the identification of, the aircraft flight control surface.

Abstract: A system configuration significantly reduces the number of interconnections needed between an electromechanical actuator (EMA) and an EMA controller (EMAC) while maintaining redundancy and other safety aspects needed by the target application. This allows simplification of communication interfaces between multiple sensors in the EMA and EMAC and unification of the interface to multiple sensors inside the EMAC, leading to cost and weight reduction that can be significant for many aerospace products and applications, including unmanned vehicle (e.g., UAM/UAV) applications.
