Publication number: US20220025907A1
Application number: 17/494,207

Abstract:
An Environmental Control System (ECS) for an aircraft includes a ram air system having a ram inlet and a ram outlet. The ECS includes a cabin air compressor motor, a diverter valve, and a dedicated outlet. The cabin air compressor motor has a motor inlet passage and a motor outlet passage with the motor inlet passage being coupled to the ram inlet. The diverter valve includes a first diverter inlet, a first diverter outlet, and a second diverter outlet. The first diverter inlet is coupled to the motor outlet passage. The dedicated outlet is connected to the first diverter outlet in a flight mode of operation of the aircraft and the ram outlet is connected to the second diverter outlet in a ground mode of operation of the aircraft.

Publication number: US20220028751A1
Application number: 17/493,541

Abstract:
A heat exchanger includes a body defining a flow channel, and a pin extending across the flow channel, the pin including an at least partially non-cylindrical shape. The pin can be a double helix pin including two spiral branches defining a double helix shape. The two branches can include a uniform winding radius. The two branches include a non-uniform winding radius.
The non-uniform winding radius can include a base radius and a midpoint radius, wherein the midpoint radius is smaller than the base radius. The two branches can be joined together by one or more cross-members.

Publication number: US20220010730A1
Application number: 17/486,237

Abstract:
A fluid injection system can include a main flow line, a primary flow line connected to the main flow line, and a primary flow valve disposed between the primary flow line and the main flow line and configured to allow injectant flow to the primary flow line from the main flow line in an open primary flow valve state, and to prevent injectant flow to the primary flow line from the main flow line in a closed primary flow valve state. The system can include a secondary flow line connected to the main flow line and a secondary flow valve disposed between the secondary flow line and the main flow line and configured to selectively allow injectant flow to the secondary flow line from the main flow line in an open secondary flow valve state, and to prevent injectant flow to the secondary flow line from the main flow line in a closed secondary flow valve state. The system can include a primary purge branch configured and a secondary purge branch configured to be in fluid communication with a purge gas line to receive a purge gas flow from the purge gas line.
