Abstract:This project will evaluate potential methods for replacement of worn seat cushions used in energy absorbing seats. Streamlined approaches to the replacement of worn cushions in aircraft seats have been requested by the aviation industry. The FAA developed a method for seats that do not require energy absorption (Part 25 and Part 23 passenger) based on rigid seat performance as a reference point. This method may not be valid for energy absorbing seats used in Part 27/29 and Part 23 pilot seats. As part of an effort to evaluate streamlined approaches, this project will characterize the seat and occupant response of typical energy absorbing seats. This dataset contains sled test data of anthropomorphic test devices seated in a rigid seat and a real aircraft seat pitched up at 30° with respect to vertical. This data is created by physical experiments. Sensors include load cells and accelerometers. Data also includes video from high-speed cameras and photos from still cameras. The tests were conducted from 2017 to 2020. No existing data was be used for this test series. It is anticipated that Aircraft seat manufacturers and test laboratories will benefit from access to this data as they design and test real aircraft seats and restraints. This dataset will also provide a public record to support potential rulemaking.
