Deicing system integrated with an air management system and advanced inlet air connection valve

An aircraft, comprising:

• a pressurized cabin;
• and
• a pneumatic de-icing system, the pneumatic de-icing system comprising:
• a de-icer flow valve;
• an accumulator;
• and
• a source control valve, wherein the source control valve is fluidly coupled to the de-icer flow valve and wherein the source control valve is configured to supply pressurized air to the de-icer flow valve from either the accumulator or the pressurized cabin depending on a differential air pressure between an air pressure in the pressurized cabin and an ambient air pressure surrounding the aircraft.

A pneumatic de-icing system, the pneumatic de-icing system comprising:

• a de-icing assembly;
• a pneumatic inlet valve, wherein the pneumatic inlet valve is fluidly coupled to the de-icing assembly;
• a de-icer flow valve, wherein the de-icer flow valve is fluidly coupled to a first port of the pneumatic inlet valve and wherein the de-icer flow valve is configured to supply pressurized air to the pneumatic inlet valve during an icing event;
• an ejector, wherein the ejector is fluidly coupled to a second port of the pneumatic inlet valve and wherein the ejector is configured to supply a vacuum to the pneumatic inlet valve.
