The Donor and Acceptor units make up the Inter-connect Assembly. The donor is a single or dual input port unit that has an extending piston. This allows for multiple inputs from alternate sources should a system require that feature. It functions when a detonating input is received from either a high energy end fitting from an ETL or a detonator (electrical or laser). The output energy of the ETL extends the Donor piston across the canopy sill line and through mechanical energy, strikes an Acceptor mounted to the canopy frame that is in-line with the Donor. The Acceptor Assembly is a receiving unit designed to function when struck by the piston of the donor. It can be either explosive loaded or inert. An explosive loaded Acceptor is designed with an internal transfer charge similar to those discussed in the previous Initiator section.
To function the Acceptor, the Donor’s piston strikes a piston on the Acceptor shearing a lip and driving a firing pin. In the explosive loaded acceptor the firing pin initiates dual percussion primers that initiate Lead Azide and then HNS resulting in a detonating output to an attached ETL. In the case of the inert Acceptor, the firing pin is driven in a percussion primer tipped RDCTL and initiates the ETL. The Acceptor allows the sequence to continue on to the canopy mounted CFS / TRS components. This Interconnect Assembly eliminates the need to disconnect components during canopy assembly removal. There is no flexible transfer line or connecting cable/linkage across the canopy sill required.
