AEROSPACE ENGINEERING DUES TO GLOBAL SUSTAINABILITY

(STEF92 Technology, 2018-06-20, Dumitru-Dorin Prunariu)

Show more

Aerospace engineering is the engineering field concerned with aircraft and spacecraft development and operating. Thus it correspondingly has two major and actually overlapping sectors, as aeronautical and astronautic engineering. Aeronautical engineering was the original term for the field, but as flight technology advanced to include craft operating in outer space as well, this means the field of astronautics, the broader term of aerospace engineering has come since a while into common use. Aerospace engineering,...

ANALYSIS LUNAR MAPS USING MULTIFRACTAL METHOD

(STEF92 Technology, 2018-06-20, Alexey Andreev)

Show more

The aim of the present work is to develop a fractal method for space maps analysis. Although there are accurate theories of lunar motion in the dynamic coordinate system based on lunar laser ranging and space measurements with an accuracy up to multiarcseconds, analysis of various models of the lunar figure is a complicated problem. The reason for it is that the determination of a reference system for coordinate data and assessing its authenticity are difficult. In order to solve the problem, a comparative method,...

BUILDING PHYSICS REQUIREMENTS AND ARCHITECTURE STUDENTS

(STEF92 Technology, 2018-06-20, Kristýna Schulzová)

Show more

The environmental performance of buildings needs to be considered in the early stages of the design process. Therefore, emphasis is nowadays placed in integrating the teaching of building performance with the design studios at schools of architecture. Preparing students for the complex role of an architect as a coordinator of all the aspects of a building design is gaining more and more importance.This article describes and compares the methods of teaching building performance to architecture students at several u...

COMPUTER DETERMINATION OF OPTIMAL PARAMETERS FOR THE TELESCOPE PLACED ON THE LUNAR SURFACE

(STEF92 Technology, 2018-06-20, Alexey Andreev)

Show more

The aim of the present paper is to give a brief review of results of computer simulating observations of the lunar rotation from the lunar surface. The simulation of physical libration of the Moon using the lunar telescope was performed on the basis of multiparametric analysis. High expectations in terms of obtaining accurate data on physical libration of the Moon are linked with SELENE Japanese project. The project implies an installation of the optical telescope at one of the Poles of the Moon. The observation o...

CONFIGURATION OF SOURCES OF EARTH-S MAGNETIC FIELD OBTAINED BY SOLVING INVERSE MAGNETOMETRY PROBLEM

(STEF92 Technology, 2018-06-20, В. А. Кочнев)

Show more

Sources of magnetic field are often approximated by dipoles or current loops, however it this work they are approximated by magnetized prisms instead, which is possible due to equivalency between magnetized objects and currents. Distribution of effective magnetization is then obtained by solving inverse magnetometry problem using the adaptive method of refining the unknown values based on discrepancy between initial values and model values. Z-components of Earth?s magnetic field in IGRF-2005 model in geocentric co...

DEVELOPMENT OF NEW METHODS OF AUTO- AND CROSS-CORRELATION ANALYSIS OF QUASI-STAR OBJECTS- X-RAYS INTENSITY

(STEF92 Technology, 2018-06-20, Natalya Demina)

The present paper demonstrates capabilities of flicker-noise spectroscopy (FNS) as a phenomenological approach to the analysis of astrophysical objects? time signals using an example of the study of quasars radio-wave radiation dynamics in various frequency ranges (S band (2 GHz) and X band (8 GHz)). The promise of FNS application to the study of signals generated by accreting astrophysical objects is caused by inclusion of informational parameters characterizing the components of time sequences in various frequen...

EFFICIENT USE OF WATER IN AGRICULTURAL CROPS BASED ON SATELLITE INFORMATION

(STEF92 Technology, 2018-06-20, Vergil Muraru)

Show more

In agriculture, drought is a particularly harmful natural factor. In some regions, it manifests in most agricultural crops by a moisture deficiency or an unfavorable distribution of rainfall in relation to crop requirements.To reduce the effects of drought and increase production in agriculture, it is necessary to irrigate the controlled supply of soil with additional amounts of water than those received under natural conditions, so as to ensure high and constant agricultural output.Plant development is determined...

ELASTOMERIC COMPOUNDS FOR SPACE APPLICATION

(STEF92 Technology, 2018-06-20, Maria Daniela Stelescu)

Show more

Sealing solutions play a crucial role in any space application. In this paper we present the production and characterization of elastomeric composites for rubber seals used to prevent unwanted loss of gas or liquid. We selected the following types of elastomers: ethylene-propylene-diene terpolymers (EPDM), butyl rubber (IIR) and bromobutyl rubber (Br-IIR) that have a good behaviour in the low temperature conditions of the cosmic space. Two bipolymeric EPDM/IIR and EPDM/Br-IIR compounds were made, containing other ...

IMPROVED MODEL OF A TETHERED SPACECRAFT SYSTEM WITH ARTIFICIAL GRAVITY

(STEF92 Technology, 2018-06-20, Andrei Craifaleanu)

Show more

Maintaining health and physical condition of astronauts during long-duration space missions requires measures to prevent microgravity effects. At present, such measures consist in practicing certain physical exercises, in using elastic suites, as well as in special medication. However, the efficiency of these solutions is limited. An alternative approach, technologically more difficult, but considerably more efficient, consists in producing a state of artificial gravity in the module inhabited by the crew. Such a ...

Currently, the southern polar region of the Moon is considered as the priority landing area for the planned lunar mission Luna-25 (Moon-Globe). Nevertheless, in this paper we have examined some areas in the North Pole region of the Moon as possible landing sites for future lunar missions. For a research we have chosen some areas located in the northern polar region: area of a crater Peary (88,9?N, 32?E), area in vicinity of Rozhdestvenskiy U crater (84,9 В° N, 152 В° E) and a Nansen F crater (84,95 В° N, 62,44 В° ...

Space weather can be monitored from the ground (astronomic/astrophysics observations and geomagnetic observatories) and from space (satellite data). Optical instruments (telescopes on the ground) recording the number of sun spots, as well as to viewing aurora, but these observations are affected by the weather from Earth's atmosphere. Observation from space does not have such a limitation. In the last years,satellites and spacecraft have monitoring the space weather. Through cooperationbetween European Space Agenc...

The present paper focuses on describing the method of bringing dynamic space images of various celestial objects to the uniform reference system. This approach is designed to analyze coordinate and time parameters of cosmic bodies in various phase spaces.Based on this method, images of the Moon and stellar areas obtained with CCDmatrixes were studied. As a result, reducing the images to the single system achieved the accuracy between 0.05 and 0.11 arc seconds by declination and between 0.04 and 0.13 arc seconds by...
