Experimental and numerical helicopter pilot characterization for aeroelastic rotorcraft–pilot coupling analysis

Pilot–vehicle interaction represents a critical aspect of aircraft design. Very low-frequency, voluntary although unintentional interaction has been extensively investigated in fixed and rotary wing aeromechanics. Higher frequency, involuntary and thus passive interaction received similar attention in fixed wing aeromechanics, but not as much for rotary wing. The results of an experimental campaign for the characterization of the passive behaviour of rotorcraft pilots' biomechanics are presented. A flight simulator has been used to excite human subjects. The accelerations of their limbs and the motion induced by the vibrations of the limbs in the control inceptors have been recorded. The vertical, longitudinal and lateral directions have been independently excited, while measuring the motion of the arm directly involved in the control inceptor mostly affected by motion in each direction, namely the left and the right arms for the collective and the cyclic sticks, respectively. The frequency domain response has been evaluated; resulting noteworthy behaviour is discussed, addressing its relevance in modelling the passive behaviour of pilots within the bioaeroservoelastic rotorcraft analysis. The measurements of human body impedance, under realistic cockpit motion, are used to identify the direct transfer functions between the motion of the seat and the controls inadvertently fed back into the rotorcraft.

Air Travel and TB: An airline perspective

The commercial airline industry in the 21st century is a global business, able to transport large numbers of people to almost any part of the world within a few hours. There has long been concern in public health circles about the potential for transmission of communicable diseases, such as TB, on board aircraft. The recent threats from novel and emerging infectious diseases including SARS and pandemic flu has facilitated unprecedented levels of cooperation between international industry representatives, regulators and public health authorities in addressing the issues of air travel and communicable disease. This paper reviews the regulatory environment, ways in which the risks are mitigated through aspects of aircraft design, opportunities for prevention by identifying individuals who may be suffering from a communicable disease prior to flight and the approach used in managing suspected cases of communicable disease on board aircraft.

Some Aspects of Aircraft Design and Manufacture for Limited Production

The emphasis in this paper is on design because the author is engaged on design work and, therefore, is more competent to deal with design than with manufacture. In any discourse on design, however, consideration must be given to the available capacity for manufacture, as this has a considerable bearing on the subject.

Aerodynamics for Engineers

IN these articles an attempt will be made to provide an introduction to a large subject specially serviceable to engineers. Restrictions on space make themselves felt in various ways. Proper acknowledgments cannot be given for the sources of information beyond mention of the books of Bairstow, Lamb, Cowley and Levy, and Glauert, to which frequent reference has been made. No account can be included of the fascinating and often instructive historical development of the science; it must be assumed that proofs of various essential theorems will be sought in text‐books of Engineering, Mathematics and Physics; lastly, there can occur little opportunity for the working of illustrative examples upon which a proper grip of the subject greatly depends. The engineer of experience will detect much that, with slight generalisation, could be made capable of important use in other branches of his profession, but in this treatment we shall keep closely in view the scientific aspect of aircraft design, structural strength apart.
