The Prospect for the Launche of a Mini Unmanned Aerial Vehicle from an Unmanned Surface Vehicle

Publié en ligne: 29 Mar 2018
Pages: 5 - 26

Résumé

Abstract

Due to the growing interest in the problems of cooperation among unmanned vehicles, in the article the proposition of the system for launching a mini unmanned aerial vehicle (mini-UAV) from an unmanned surface vehicle (USV) has been presented. The solution differs from the previously used in this that instead of the commonly used rotorcrafts it concerns the ability to start the mini aircraft with the help of pneumatic or rubber launcher. The results of the computer simulation have con-firmed the possibility of implementation of that kind of system.

Methods for Treatment of Decompression Sickness Developed During Wreck Penetration

Publié en ligne: 29 Mar 2018
Pages: 27 - 53

Résumé

Abstract

This article is one of the series articles relating to the DiveSMART project conducted to improve coordination procedures used in international underwater rescue operations in the Baltic Sea. The project DiveSMART Baltic has received the ‘flagship status’.

The article is the third in the planned cycle of articles relating to efforts made at the Naval Academy within the framework of DiveSMART Baltic project. It includes scenarios of treating decompression sickness acquired by divers during a rescue operation or after completed their decompression. These issues are connected with the work package four ‘Medical treatment’ of the DiveSMART Baltic project: Identifies methods for different medical treatments in operational areas.

The Concept of Microprocessor Registration System of Energy Consumption of an Underwater Vehicle

Publié en ligne: 29 Mar 2018
Pages: 55 - 68

Résumé

Abstract

The article, on the basis of the underwater vehicle ‘Głuptak’ intended to combat naval mines, outlines the general concept of the microprocessor system of registration of change of electricity stored in batteries for the underwater vehicle at the implementation time of the set task. Registration system the amount of energy allows you to optimize the implementation of the working time of the underwater vehicle drive system in conditions of interference type underwater sea current.

NATO Standardization Documents for Mine Countermeasure and Their Updating as an Area of Scientific Activity

Publié en ligne: 29 Mar 2018
Pages: 69 - 84

Résumé

Abstract

NATO standardization documents are the basis for action in many areas of NATO military activity and their affiliated organizations. The development of the NATO standardization documentation has been on-going for more than 60 years, and their content provides a reliable basis for joint action in a unified manner, enabling interoperability in many areas of NATO operations. The article is divided into three parts, the first of which deals with the general principles of NATO standardization, the second part describes the standardization documents related to the measurement of the ship’s signatures in aspect of the mine countermeasures and the third describes the participation in research project of NATO — RIMPASSE 2011 Trial. One of the their task was to verify and update NATO standardization documents including AMP-15.

Operational Tests Results of the Naval Gas Turbines Operated by the Polish Navy

Publié en ligne: 29 Mar 2018
Pages: 85 - 103

Résumé

Abstract

This article is a continuation to the theme of the article Operational diagnostics synthesis of the naval gas turbines operated by the Polish Navy published in SJ of PNA No. 1/2017. This article presents examples of results of energy research carried out by the Polish Naval Academy in the years 1985–2016, for the purpose of operational diagnostics of this type of engine, operated by the Polish Navy. The research conducted since 1985 covered four types of naval gas turbines (DE 59, DR 76, DR 77 and LM 2500), with a total of 24 engines. Currently in operation there are four LM 2500 type engines. In the near future, another LM 2500 engine will commence operations, along with a project 661M patrol ship. The energy research covers the engine start-up process, their operation in idle mode and within the whole range of load variations, as well as the process of engine stopping. The article presents examples of characteristics specific to the above processes, determined based on the results of studies of individual types of engines. Currently ongoing studies allow for constructing strategies for naval gas turbines, operated in the Polish Navy, according to technical condition.

Report on Research with Biomimetic Autonomous Underwater Vehicle — Low Level Control

Publié en ligne: 29 Mar 2018
Pages: 105 - 123

Résumé

Abstract

The paper presents the first part of the final report on all the experiments with biomimetic autono-mous underwater vehicle (BAUV) performed within the confines of the project entitled ‘Autonomous underwater vehicles with silent undulating propulsion for underwater ISR’, financed by Polish National Center of Research and Development. The report includes experiments in the swimming pool as well as in real conditions, that is, both in a lake and in the sea. The tests presented in this part of the final report were focused on low-level control.

The Analysis of the Digital AC Motor Speed Control System Operation

Publié en ligne: 29 Mar 2018
Pages: 125 - 136

Résumé

Abstract

The article presents the analysis of the automatic alternate current motor control system, carried out by the author. The automatic control system has been implemented on the existing laboratory stand, containing: the squirrel-cage asynchronous motor and the frequency inverter. The existing stand imposed one of the available speed control methods for the motor and the necessity of the appropriate elements selection for the automatic control system [1]. The automatic control system has been designed and created as the constant value follow-up digital controller. To designate the parameters of the control object the unit step method of was used. After registering the output changes caused by the unit step, the characteristic curve was received that allowed to determine the alternative transmittance of the control object which, in turn, has made possible to find the appropriate controller settings.
