Abstract: A defrost cycle time of an aircraft vapor cycle refrigeration system is adaptively controlled. A pressure of refrigerant at an inlet of a compressor of the vapor cycle refrigeration system is sensed. A defrost cycle of the vapor cycle refrigeration system is initiated in response to the sensed pressure being less than a threshold pressure. The defrost cycle is terminated upon expiration of the defrost cycle time. The defrost cycle time is based upon a time duration of the cooling cycle.

Abstract: Embodiments relate to adjusting cabin pressure based on ambient conditions to achieve a target aircraft inflow. An aspect includes receiving a number of occupants on an aircraft. The ambient conditions on the aircraft are monitored and an occupant threshold limit is determined for the aircraft based on the ambient conditions. If it is determined that the number of occupants exceeds the occupant threshold limit, the cabin pressure is reduced in the aircraft according to embodiments. The cabin pressure in the aircraft is reset in response to the occupant threshold limit being increased due to changing ambient conditions.

Abstract: Operational parameters of an aircraft vapor cycle refrigeration system are measured via a plurality of sensors while the vapor cycle refrigeration system is operating. The measured operational parameters are transmitted to a computer system. The computer system generates, using a first reduced order model corresponding to an unclogged state of a filter of the vapor cycle refrigeration system, a first predicted discharge pressure of a compressor based on the measured operational parameters. The computer system generates, using a second reduced order model that corresponds to a clogged state of the filter, a second predicted discharge pressure of the compressor based on the measured operational parameters. The computer system determines a remaining useful life of the filter based on the first predicted discharge pressure, the second predicted discharge pressure, and a measured discharge pressure of the compressor. The computer system outputs an indication of the remaining useful life of the filter.

Abstract: A computer-implemented method for designing a built-in test is described. The method includes receiving, via a processor, a subsystem model including system parameters for a heat exchanger, wherein each of the system parameters includes a sensor variance; determining, via the processor, a test design vector based on one or more of the system parameters; and designing, via the processor, the built-in test based on the test design vector.
