Ejection seat testing requirements lead to the development of the Grumman Alderson Research Dummy (GARD) by Alderson and Arrone, of Grumman and CG dummies by Alderson at Humanetics in the 1960’s through the 1990’s. These rugged dummies measured the dummy whole body motions throughout the ejection sequence and sent data by telemetry to a ground station.
1960-The Gard Dummy (Grumman - Alderson Research Dummy) The development of the Gard Dummy became a necessity when aircraft ejection - seats with rocket catapults reached the testing phase. Such seats were designed so that the resultant vector of rocket thrust passes through the center of gravity of the man-seat system. Misalignment would produce a rotational moment and tend to impart a spin to the system.
