The automobile car cabin is complex man –machine interface. Two main goals of Heating Ventilation and Air conditioning System is providing thermal comfort and save energy. Comfort is a subjective feeling and hard to model mathematically. This is because thermal comfort is influenced by many variables such as temperature, relative humidity, air velocity and radiation. Aim of this paper is to des...

Full-scale furnished cabin fires have been studied experimentally for the purpose of characterising the post-crash cabin fire environment by the US Federal Aviation Administration for many years. In this paper the Computational Fluid Dynamics fire field model SMARTFIRE is used to simulate one of these fires conducted in the C-133 test facility in order to provide further validation of the compu...

Helicopters are susceptible to high vibratory loads, excessive noise levels and poor flight stability compared to fixed-wing aircraft. The multidisciplinary nature or helicopter structures offers many opportunities for the innovative smart structure technology to improve helicopter perfonnance. This paper provides a review of smart structures research at the National Research Council Canada for...

This paper describes a wireless sensor network prototype with the use of reconfigurable hardware for airliner cabin environment research. Commercial airplane passengers and crews breathe a mixture of outside and re-circulated air, similar to many homes and offices. But the cabin environment is unique, due to the proximity of the passengers, the need for cabin pressurization, the low humidity, a...

AIMS To investigate whether length of employment as a cabin attendant was related to breast cancer risk, when adjusted for reproductive factors. METHODS Age matched case-control study nested in a cohort of cabin attendants. The cases were found from a nationwide cancer registry (followed up to end of year 2000) and the reproductive factors (age at first childbirth and number of children) from...

M ost of us have the experience of travelling on aeroplanes and are impressed by the cleanliness and orderliness of the cabin that welcome us together with the friendly and smiling faces of the aircrew every time we board an aeroplane. The cleanliness and orderliness of the cabin are the results of the hard work of heroes behind the scene— the aircraft cabin cleaners. The work of these cleaners...

It is known that PMA (phorbol-12-myristate-13-acetate) can activate the classical and novel protein kinase C isoenzymes (cPKC alpha, beta, gamma and nPKC delta, epsilon, eta, theta), while the calcium ion can induce only the activity of cPKC. Calcineurin binding protein (Cabin 1) belongs to the group of endogenous inhibitors of calcineurin. Cabin 1 becomes hyperphosphorylated in response to PKC...

In this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. To achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. The length of gasper air flow was compared with the distance between gasper outlet and...

Gaspers installed in commercial airliner cabins are used to improve passengers' thermal comfort. To understand the impact of gasper airflow on the air quality in a cabin, this investigation measured the distributions of air velocity, air temperature, and gaseous contaminant concentration in five rows of the economy-class section of an MD-82 commercial aircraft. The gaseous contaminant was simul...
