Automatic cargo hook release assembly

摘要

A method of releasing cargo suspended from at least one cargo hook release pendant in a suspension system coupled to a cargo hook release system includes receiving a voltage release signal at a cargo hook control interface and a cargo release harness assembly; receiving an energizing voltage signal at the cargo release harness assembly; energizing a relay in response to receiving the energizing voltage signal, the relay being electrically coupled to the cargo release harness assembly; automatically transmitting the voltage release signal from the cargo release harness assembly to at least one cargo hook release pendant in response to energizing the relay; and automatically releasing the cargo from at least one cargo hook release pendant in response to automatically transmitting the voltage release signal. Also, the cargo hook release system includes the cargo hook control interface, the cargo release harness assembly, and at least one cargo hook release pendant.

1. A cargo hook release system for releasing cargo suspended from at least one cargo hook release pendant in a suspension system, comprising:
a cargo hook control interface comprising a manual-normal hook release switch and a manual-emergency hook release switch; a cargo release harness assembly including a relay electrically coupled to a cargo harness interface; a flight control computer including a processor that is configured to transmit an energizing voltage signal to the cargo release harness assembly; and at least one cargo hook release pendant operably coupled to the cargo harness interface; wherein the relay is in a de-energized condition during normal operation of the cargo hook release system, and wherein the relay is energized during automatic release of the cargo; wherein each of the cargo hook control interface and cargo release harness assembly is operable to receive a voltage release signal indicative of activation of the cargo hook release system; and wherein the relay is operable to selectively transmit the energizing voltage signal from the flight control computer to the at least one cargo hook release pendant.
