Evaluation of Standard Gear Metrics in Helicopter Flight Operation

Six well known gear metrics were computed from vibration signals previously recorded from an OH-58C helicopter under controlled flight conditions. For the pinion gear studied, an optimal number of rotations was found for the average. Stationarity decreased as the number of rotations increased. It is conjectured that the dynamic environment of the helicopter is the primary contributor to the dec...

Eye Tracking Metrics for Workload Estimation in flight Deck Operation

Flight decks of the future are being enhanced through improved avionics that adapt to both aircraft and operator state. Eye tracking allows for non-invasive analysis of pilot eye movements, from which a set of metrics can be derived to effectively and reliably characterize workload. This research identifies eye tracking metrics that correlate to aircraft automation conditions, and identifies th...

Field quantification of physical exposures of police officers in vehicle operation.

Mobile police officers perform many of their daily duties in their vehicles. Combined workspace inflexibility and prolonged driving create potential musculoskeletal injury risks. Limited research exists that quantitatively describes postural and load exposures associated with mobile police work. The purpose of this study was to characterize officer activity during a typical workday and identify...

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...
