AIMS To determine the cancer incidence in Swedish cabin crew. METHODS Cancer incidence of cabin crew at the Swedish Scandinavian Airline System (SAS) (2324 women and 632 men) employed from 1957 to 1994 was determined during 1961-96 from the Swedish National Cancer Register. The cancer incidence in cabin crew was compared with that of the general Swedish population by comparing observed and ex...

This paper conducts an investigation towards main aircraft cabin parameters. The aim is two-fold: First, a handbook method is used to preliminary design the aircraft cabin. Second, an objective function representing the “drag in the responsibility of the cabin” is created and optimized using both an analytical approach and a stochastic approach. Several methods for estimating wetted area and ma...

This paper presents results of a parametric study performed on an automotive air-conditioning (AAC) system of a passenger car. The goals are to assess the effects of varying the volumetric flow rate of supply air, number of occupants, vehicle speed, and the fractional ventilation air intake (XOA), on the dry-bulb temperature and specific humidity of the air inside the passenger’s cabin, and on ...

This paper presents a cost-effective method to increase the COP and utility of a domestic refrigerator using R-134a refrigerant. A cabin was installed on the top of a domestic refrigerator with condenser coils of refrigerator serving as heating coils inside the cabin. Known quantity of water was heated by the condenser coils (due to convection currents) thereby increasing the overall COP of the...

AIM The aim of this study was to describe and compare the self-assessed occupational health among female nurses, cabin crew and teachers, in relation to their working environment. BACKGROUND Similarities between the three occupations, i.e. predominantly female and service-oriented, render them interesting in comparison with respect to health and working environment. METHODS The participants...

Measurements of air humidity, temperature, carbon dioxide (CO2), respirable particles, ozone, nitrogen dioxide (NO2), formaldehyde, and volatile organic compounds of possible microbial origin (MVOC) were performed during 26 flights with Boeing 767-300. The mean temperature in cabin was 22.2 °C (range 17.4-26.8 °C), and mean relative air humidity was 6% (range 1-27%). The CO2 during cruises was ...

Abstract The sonic load of the engine is input for cabin noise design and acoustic fatigue verification in civil aircraft. Based on static database, an engineering prediction method blended wing body aircraft flight developed. In process prediction, sound source position correction, geometric diffusion, effect airframe scattering component are considered. air-frame level simulated analyzed. ove...

Several dramatic accidents have emphasized certain deficiencies in cockpit-cabin coordination and communication. There are historical, organizational, environmental, psychosocial, and regulatory factors that have led to misunderstandings, problematic attitudes, and suboptimal interactions between the cockpit and cabin crews. Our research indicates the basic problem is that these two crews repre...

In this paper, a study of the concurrent engineering design for the environmental friendly low cost aircraft cabin simulator is presented. The study describes the used of concurrent design technique in the design activity. The simulator is a testbed that was designed and built for research on aircraft passenger comfort improvement of long haul air travel. The simulator consists of an scale down...
