Compliance
14 “Aerospace” CFR Part 23.562, 14 “Aerospace” CFR Part 25.562, 14 “Aerospace” CFR Part 27.562, 14 “Aerospace” CFR Part 29.562, FAA AIR-100-3-3-2000, SAE Technical paper 1999-01-1609.
The FAA Hybrid III 50M Dummy is an FTSS modification of the Hybrid III 50th percentile male automotive crash test dummy developed by General Motors, anthropometrically based on the height and weight of a 50th percentile dummy for adult American males. The design of this dummy incorporates the range of motion, centre of gravity, and weight of body parts as defined by the Society of Automotive Engineers Anthropometric Study to simulate the weight of a human subject. The weight and seat height measurements were slightly modified in the FAA dummy. The dummy was modified in the lower torso and legs to equip the dummy for testing, and in accordance with FAA regulations for an emergency landing dynamic conditions, the FAA dummy was adjusted to an upright seated position, replacing the "relaxed and slouched" state of the car dummy. The sensors were visually measured to measure spinal loading as required by aviation regulations.
The dummy was manufactured in accordance with 14 CFR parts 23.562, 25.562, 27.562, and 29.562 of the Code of Federal Regulations (CFR), combined with US anthropometric statistics and the product brochure for the Humanetics Hybrid III 50th FAA dummy. The geometry and mass distribution of the dummy are consistent with that of the Humanetics dummy, and critical areas are calibrated to ensure good bionic biomechanical properties.

The FAA Dummy consists of six parts:
Head
The dummy head assembly consists of the cranial skin, skull, posterior cranium bone, posterior cranial skin and sensor mounting frame. The dimensions of the dummy conform to the anthropometric equivalent percentile and the PVC cast skin wrapped around the aluminum skull gives the head a realistic biomechanical bionic character that simulates the response of the human head when subjected to external impact.
Neck
The dummy neck assembly consists of the neck joint, steel rope, neck assembly, and neck frame.
The steel rope passes through the top center hole of the neck assembly, the ball end of the wire rope snaps into the ball slot of the neck assembly, and the threaded sleeve of the wire rope passes through the neck frame and is secured with a hexagonal nut. The locking torque of the hexagonal nut adjusts the stiffness of the neck assembly, which is made of an aluminum skeleton and cast rubber, to give the neck a realistic biomechanical bionic character. The rubber block on the neck joint ensures the kinematic response of the head when fitted to the head.
Upper Torso
The dummy upper torso consists of the chest skin, rib assembly, left shoulder assembly, spine assembly, and right shoulder assembly.
Arms
The dummy arm, with the right and left arms symmetrical to each other, includes the upper arm, arm connectors, lower arm, wrist connectors, and hand.
The entire arm is an external PVC and polyurethane skin with an internal steel skeleton. The upper arm, lower arm, and hand are connected to each other by arm connectors and wrist connectors, which simulate the rotational movement of the human elbow and wrist joints within a certain angle.
Hip
The dummy hip consists of the lumbar spine assembly, hip skin, femur, and abdomen. By performing hip flexion tests, the hip is guaranteed to have realistic biomechanical bionic properties and can be fitted with lumbar spine force sensors, pelvic acceleration sensors, etc. for measuring human hip injuries under different working conditions.
Legs
The dummy leg structure is symmetrical to each other on the left and right, and consists of the thigh skin, thigh skeleton, sensor simulator, knee assembly, calf assembly, and foot respectively.
The legs of the FAA dummy are calibrated to have realistic biomechanical bionic properties and motion response characteristics by calibrating the knee, slider, and foot.
