Overview of the Flight Dynamics Subsystem for Korea Pathfinder Lunar Orbiter Mission

Korea’s first lunar mission, the Korea Pathfinder Lunar Orbiter (KPLO), aims to launch in mid-2022 via the Space-X Falcon-9 launch vehicle. For the successful flight operation of KPLO, the Korea Aerospace Research Institute (KARI) has designed and developed the Flight Dynamics Subsystem (FDS). FDS is one of the subsystems in the KPLO Deep-Space Ground System (KDGS), which is responsible for the overall flight dynamics-related operation. FDS is currently successfully implemented and meets all of the requirements derived from the critical design phases. The current work addresses the design and implementation results for the KPLO FDS. Starting from overviews on KPLO payloads, bus systems, and mission trajectory characteristics, a review on KDGS is also treated briefly. Details on the design philosophy, unique characteristics, and functionalities of all six different modules nested inside the FDS with its Graphical User Interface (GUI) design are discussed. Moreover, efforts currently devoted to the flight operation preparation of the KPLO are summarized, including many collaborative works between KARI and the National Aeronautics and Space Administration (NASA) teams.

Development of a multipurpose test rig and validation of an innovative rotorcraft vertical tail - TAILTEST

TAILTEST 9th call of the CS2 project started in the 2019 year is aimed at the development of a multipurpose test rig for validation of an innovative rotorcraft vertical tail. It is conducted in Czech Aerospace Research Centre (VZLU) as coordinator cooperating with the Greek Athena Research centre (Athena RC) as a participant. The project was initiated by Fokker Aerostructure Company and as part of the project chain is contributing to conceptual aircraft type of Next Generation Civil Tiltrotor with the reduction of fuel consumption and CO2 emissions by lowering the structural weight of a rotorcraft tail through the application of thermoplastics. The paper summarized project objectives, concept and approach and main objectives of technical work packages.

Methodology for evaluating the effectiveness of integrated automation in aerospace industry

Aerospace (remote) methods today have become one of the most effective means to study the earth's surface. Taking into account the expansion of the range of tasks that the aerospace industry faces nowadays, as well as the fact that hyperspectral analysis of large volumes of data obtained during aerospace research is time-consuming and costly, the need for the introduction of automated control systems for aerospace enterprises is essential. The article is devoted to the study of approaches to evaluating the efficiency of the integrated automation in aerospace organizations. In the process of research, a technique based on the use of mathematical apparatus of fuzzy numbers and including an assessment of the productivity and stability of functioning of automation systems, as well as an analysis of the reliability of information exchange and security of information transmission. Therefore, the practical and theoretical significance of the chosen research topic is not in doubt.

The role of aerocosmic research in metallogenic prediction (on the example of antimony-mercury ore formation deposits in Azerbaijan)

Mercury degassing is a global process. In geological development, it begins with the formation of deep fractures that can penetrate the great depths of the mantle. As the linearity lengthens, the temporal degassing and intensity of mercury weaken this connection with the depths of its individual parts and the Earth, or the period of strengthening of this connection will vary depending on the development of the characteristics observed. The concentration of mercury and antimony-mercury ores along the outer frame of circular and oval and other structures can most likely be explained by the Earth's total mercury degassing. In our opinion, the ideal situation is the junction of circular, oval, and other structures with linear nodes, where industrially important deposits of minerals can be formed. Key words: mercury, aerospace research, metallogenic prediction, minerals

Vortices inside a single-stage axial air turbine captured by Particle Image Velocimetry

Particle Image Velocimetry (PIV) is an experimental method of fluid research resulting into a spatially resolved two-dimensional velocity field. We measured the velocity inside a single-stage axial test turbine at the Czech Aerospace Research Centre. We studied the axial × tangential plane just behind the rotor wheel at the tip radius under three regimes: underloaded, designed and overloaded ones. We found individual vortices in the instantaneous snapshots and we analyze their properties statistically.

Strategies and Technological Advances in Removing Space Debris Satellite

Now days we are sending many satellites into the space which are mainly useful for communication. Till now we have sent many satellites and we have dropped many things in the space like those dead particles revolves around the earth in Low Earth Particles (LEO). This derbis became a problem. It will be a risk to other particles which are revolving in LEO. If we doesn’t take any steps it will lead to collisions and destroy all communication system. The Japan Aerospace Exploration Agency (JAXA) Aerospace Research is studying a micro-satellite space derbi removal scheme. This paper discuss about the Key technologies, strategies and specifications of removing derbis satellite
