Abstract
A pallet restraint system for use in the cargo bay of an aircraft in an air drop sequence. The system assures an equal application of the parachute extraction force and simultaneous release of all load sensitive latches by means of hydraulic interconnectors between the latches to vary their position.
Claims6
A restraint system for use on floor in aircraft cargo bay to engage and hold a pallet in air drop sequence comprising:
- two load sensitive latches moveably mounted on said floor in such a manner that they will engage one side of the pallet;
- hydraulic actuators attached to said latches and to said cargo floor to provide movement to said latches;
- hydraulic interconnection between hydraulic actuators to provide transfer of hydraulic fluid from one actuator to the other, thereby moving the latches into full engagement with said pallet, and
- guide means to engage the side of the pallet opposite the load sensitive latches to assist in restraining and guiding of said pallet from said aircraft cargo bay.

A pallet restraint system for use in floor of cargo aircraft during an air drop sequence comprising:
- two load sensitive latches mounted for rotational movement on said floor of the aircraft to engage one side of said pallet;
- guide means attached to the aircraft floor to engage the side of the pallet opposite said latches to assist in the restraint of the pallet and guiding of the pallet out of the aircraft in the air drop sequence;
- hydraulic actuators attached to the floor of the aircraft and to said latches to provide movement to said latches, and
- a hydraulic connector for transfer of hydraulic fluid from one actuator to the second to adjust the position of said actuators to provide for full engagement of said pallet, and equalization of loads among several latches.
