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...

An analysis of ight measurements made near a wake vortex was conducted to explore the feasibility of providing a pilot with useful wake-avoidance information. The measurements were made with relatively low-cost ow and motion sensors on a light airplane ying near the wake vortex of a turboprop airplane weighing approximately 90 000 lb. Algorithms were developed which removed the response of the ...

An extensive experimental investigation to study the flow structure over the wing of a fighter type configuration model has been conducted. The model used for this study was similar to the High Alpha Research Vehicle (HARV) that has been used in various European research centers for studying its force and moment characteristics. Tests were conducted at two subsonic speeds and at low to moderate...

While injuries to the spine after an airplane crash are not rare, most crashes result in fatal injuries. As such, few studies exist that reported on spine fractures sustained during airplane accidents. In this report, we demonstrate three cases of spine fractures due to crash landing of a commercial airplane. Three passengers perished from injuries after the crash landing, yet most of the passe...

We describe methods and algorithms for automated generation of multiparted airplane wings with winglets. The wings are given by one or more cross-sections (e.g. by point clouds) and their top views. The relative thickness of the wing (thickness/chord) can be varied from section to section. A rounded tip with design parameters and GC1-continuity at the crossing to the wing is automatically compu...

Schlieren imaging in wind-tunnels is extensively utilized to study the effects of air on an airplane surface. One of the interesting subjects for research is to study the effects of speed change on the airplane surface. Speed change results in occurrence of shock waves, which are visualized as lines on Schlieren images. In this paper, we study the problem of detecting speed of a plane after occ...

This paper describes a modelling approach to the dynamics of the airplane flight aimed at designing and realizing a simple but realistic ‘‘flight simulator,’’ able to mimic the longitudinal behaviour of a real airplane. The model is implemented by using the Interactive Physics simulation environment. The simulator is used to reproduce all the phases of a complete flight of a light commercial ai...
