Dynamic pressure chamber electrical passthrough

A signal passthrough kit operably engaged with a canister housing an air vehicle and an electronic assembly, the signal passthrough kit comprising:

• a backer plate operably engaged with the canister;
• a piston operably engaged with the canister, the backer plate, and the air vehicle, wherein the piston is positioned between the backer plate and the air vehicle;
• and
• a circuit card assembly operably engaged with the backer plate and positioned external to a canister chamber defined by the canister;
• wherein the signal passthrough kit is configured to output at least one signal to the electronic assembly external to a pressure chamber defined in the air vehicle.

A method comprising steps of:

• installing a backer plate of a signal passthrough kit to a canister, wherein the canister houses an air vehicle and an electronic assembly;
• installing a piston of the signal passthrough kit between the backer plate and the air vehicle inside of the canister;
• installing a circuit card assembly with the backer plate positioned outside of the canister;
• and
• installing a signal path assembly of the signal passthrough kit with the backer plate, the piston, the circuit card assembly, the air vehicle, and the electronic assembly;
• wherein the signal path assembly is configured to output at least one signal to the electronic assembly external to a pressure chamber defined in the air vehicle.
