This SAE Aerospace Information Report (AIR) provides information about impulse loads that occur during normal aircraft towing operations. An instrumented tow bar was used to characterize towing loads. Suggestions to minimize impulse loads by reducing the tow bar to tow vehicle gap are described.
Impulse loads that exceed design loads can occur during aircraft towing operations when a large gap exists between the tow bar and the tow vehicle and no damping or shock-absorbing device is present.
