Traditional biology has focused on identifying individual genes, proteins and cells, and studying their specific functions. But that kind of research can yield relatively limited insights about the whole organisms, including the human body. As an analogy, if one wanted to study an airplane, and focused on identifying the engine, wings, and seat belts, and studied their specific functions, one w...

Abstract The pilot project of new light civil turboprop aircraft, called the KhAI-90, featuring a cruising speed 350km/h, payload 600 kg at 500 km range, and equipped with two Rolls-Royce 250-B17F engines each power 420 hp (alternatively, AI-450C 450 may be installed) is presented herein. Based on developed technical task, concept for creating KhAI-90 competitive analysis prototypes’ aircraft p...

Abstract Out-of-plane mechanical properties of the riveted joints restrict performance wing box assembly airplane. It is necessary to investigate pull-through composite/metal in order guide riveting design and ensure safety assembly. The progressive failure mechanism composite/aluminum joint subjected loading was investigated by experiments finite element method. A damage model based on Hashin-...

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...

Fauconnier and Turner’s conceptual blending theory (1998) has been used to analyze many types of cognitive phenomena, particularly the role blending plays in language comprehension. In this paper we illustrate how blending also has a role in mediating expert performance, such as understanding the meaning of a chart or a navigation display. Pilots use blends to assess flight situations, predict ...

A jet airliner with 54 persons aboard was delayed on the ground for three hours because of engine failure during a takeoff attempt. Most passengers stayed on the airplane during the delay. Within 72 hours, 72 per cent of the passengers became ill with symptoms of cough, fever, fatigue, headache, sore throat and myalgia. One passenger, the apparent index case, was ill on the airplane, and the cl...

This paper presents an original experimental and numerical investigation of acoustic streaming driven by an acoustic beam reflecting on a wall. The water experiment features a 2 MHz acoustic beam totally reflecting on one of the tank glass walls. The velocity field in the plane containing the incident and reflected beam axes is investigated using Particle Image Velocimetry (PIV). It exhibits an...
