Flight Control Design and Simulation Handling Qualities Assessment of High Speed Rotorcraft
Proceedings of the Vertical Flight Society 75th Annual Forum, 2019The U.S. Army Aviation Development Directorate has developed generic high-fidelity flight-dynamics models of two advanced high-speed rotorcraft configurations - a lift offset coaxial helicopter with a pusher propeller and a tiltrotor.

Pre-slaughter handling and pork quality
Meat Science, 2015Environmental variables, as sound levels, were collected during the pre-slaughter process in 18 different Belgian commercial slaughterhouses. Four pre-slaughter phases were determined: firstly after arrival of the truck at the slaughterhouse and just before unloading, secondly during unloading, thirdly at lairage and finally while moving to the stunner.

Longitudinal handling qualities criteria - An evaluation.
Journal of Aircraft, 1965Compliance with current longitudinal handling qualities criteria is not a guaranteed acceptance of vehicle characteristics. Several criteria for satisfactory characteristics resulting from handling qualities investigations in simulators and variable-stability airplanes are reviewed; in comparison, these criteria reveal significant areas of disagreement.

Handling qualities and pilot evaluation
Journal of Guidance, Control, and Dynamics, 1986The handling qualities of airplanes have been a subject of considerable interest and concern throughout the history of piloted flight. The Wright Brothers were successful in achieving the first powered flight in large measure because they provided adequate flying qualities for the task at hand. As they became capable of flights of longer duration, they

Proceedings of the Institution of Mechanical Engineers: Automobile Division, 1969
The paper is concerned in general with quantitative methods of analysis for the general steady-state motion of an automobile and, in particular, for methods that are able to assess the non-linear characteristics of vehicles. In this context it is observed that any quantity used must satisfy three requirements; it must have a physical significance and ...

Objective evaluation of handling quality
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2002Vehicle dynamics quality is generally evaluated by two approaches: subjective evaluations using driver ratings and objective measurements of vehicle dynamics characteristics. In both approaches it is important to define features of vehicle dynamics in order to cover all aspects, but without redundancy.
