Дослідження структури порушених відкритою розробкою земель й пошук шляхів вдосконалення рекультивації залишкових виробок кар'єрів

Стаття присвячена дослідженням структури порушених земель, на ділянках з видобутку корисних копалин відкритим способом. Наведено площі порушень земель при розробці основних видів корисних копалин. Проаналізовано ризики, що виникають із несвоєчасною рекультивацією земель гірничого відводу, а також від покинутих гірничих виробок старих кар'єрів. Паралельно розглянуті обсяги відходів гірничого виробництва та їх повторне використання в якості заповнювача для залишкових вироблених просторів кар'єрів.The article is devoted to the research of land violation indicators at the extraction of minerals by surface mining method. Data gives about the land violations area at the mining key minerals. Ana-lyzed the risks from the not-on-time reclamation of the mining clam and abandoned excavations of the old quarries. In parallel considered the volumes of mining wastes and their reuse as aggregate for filling residual spaces of surface mines.Статья посвящена исследованиям площадей нарушения земель, связанных с добычей полезных ископаемых открытым способом. Приведены площади нарушений земель при разработке основных видов полезных ископаемых. Проанализированы риски, представляемые несвоевременной рекультивацией земель горного отвода, а также заброшенными горными выработками старых карьеров. Параллельно рассмотрены объемы отходов горного производства и их повторное использование в качестве заполнителя для остаточных выработанных пространств карьеров

Automatic Fuselage System Layout using Knowledge Based Design Rules

This paper introduces a tool for preliminary system placement inside an aircraft’s fuselage. Objective is to estimate the effect of design decisions on system routing, which may then be used for better weight estimation or physical modeling. The method uses a detailed geometrical model of the fuselage including cabin and primary structure. The system components and connectors are placed according to knowledge patterns. The focus is on large fuselage systems such as the environmental control system, the water&waste system and parts of the electrical system, which are the most significant in terms of size and weight

Cabin Design for Minimum Boarding Time

Single and twin aisle cabin layouts of various capacities are compared regarding their boarding and debaording time. Basis is a boarding simulation and detailed cabin layout

Integrated Tool for Cabin and Fuselage Modeling in Future Aircraft Research

The paper describes a set of software tools for cabin and fuselage engineering in conceptual aircraft design. Focus is at collaboration and inclusion of advanced analysis methods

Twin Aisle Aircraft for Short Range Operations - An Economically Attractive Alternative?

Short range air tra�c is dominated by single aisle aircraft. The average seat count of delivered single aisles has grown considerably. Single aisles are handicapped by lengthy boarding and deboarding times. Aircraft with twin aisle cabin layout may alleviate the boarding problem. But those aircraft may su�er from increased cost of operation. This paper studies how much better twin aisles fare in turnaround operations and how much more they cost to operate. These �gures are analyzed for a selection of capacities and mission ranges in order to analyze where twin aisles o�er bene�ts. The general �nding is that twin aisles are more suitable above 240 seats capacity, but may o�er superior economics even for lower capacities at short distances

Weight and Fuel saving Potential Through Changed Cabin and Fuselage Design

The paper investigates the effect of weight saving in the cabin and the effect of changed fuselage layout. Underused facilities and capabilities are removed and the aircraft becomes slightly smaller and lighter. Fuel burn is reduced by up to 9%
