Involvement in the construction of nuclear power plants worldwide is a promising direction for developing re-search and technological potential engineering general contracting companies Russia. Nevertheless, Russian companies, involved (NPPs) abroad, need to adapt foreign jurisdictions, their requirements rules applied hazardous industrial facilities, as well unique social, economic physical en...

Abstract This paper present the results of our project to develop preliminary design a jet trainer plane (JTP) with two-person crew, base version which is intended for cadet training. We first consider assumptions and requirements new aircraft, review parameters existing aircraft designs in similarly-purposed class. Next we argue certain choices, regarding layout, cockpit configuration, wing lo...

Global optimization of transport aircraft is performed to minimize fuel burn for a specified mission. The design space includes the geometry, wing airfoils, primary structure, engine size and cycle parameters, and the flight profile parameters. The method employs a number of physics-based models for structural sizing and weight estimation, viscous CFD for all major aerodynamic components, and a...

BACKGROUND DNA-based sequencing approaches are commonly used to identify microorganisms and their genes and document trends in microbial community diversity in environmental samples. However, extraction of microbial DNA from complex environmental samples like corals can be technically challenging, and extraction methods may impart biases on microbial community structure. METHODS We designed a...

Multi-disciplinary optimisation (MDO) of the outboard engine pylon of a large transonic transport aircraft is reported in this paper. The disciplines involved were structure and aerodynamics, although this paper focuses on the aerodynamic aspect. A two-level strategy was followed to solve this problem: three parameters are identified as playing a coupling role between disciplines and are addres...
