Reliability is one of the main salient assets of modern weapon systems. The estimation of the failure rate of the major subsystems of military defence systems is of utmost importance in the design of any country's overall defence system. The results of a study to estimate the failure rate of the main computer system of the launcher of a shore to sea missile launcher is presented in this study. ...

We present a student group project, which takes a different spin on the driving game genre, turning it into a racing ‘launcher’ game. This undergraduate group project that students from different disciplines (ranging from 3D animation to software development) have worked on during the second year of their degrees not only aims for students to improve their teamworking skills but also to cultiva...

The dynamics and engineering of a spiral slingatron mass accelerator are described together with the status of experiments. The potential utility of this mechanical device for space launch applications is discussed.

The SART (Space Launcher Systems Analysis) group of the German Aerospace Center DLR has the task of examining all types of future space launch systems and the thereof required engines by means of modern, computer-aided methods. One of the fundamental aims is to reduce the cost of access to space through the identification of eligible technology. Activities range from stand-alone preliminary stu...

In this paper, a new design of permanent magnet linear synchronous motor (PMLSM) for electromagnetic launcher system (EMLs) has been investigated in terms of the requisite amount of average launching thrust force and thrust force ripple minimization through finite element method. EMLs are a kind of technology used to develop thrust force and launch heavy loads with different applications includ...

This paper presents work-in-progress in assessing the usefulness of a layout complexity metric in evaluating the usability of different screen designs. The metric is based on the Shannon formula from communication theory. Initially the metric was applied to thirteen Windows applications where thirty subjects were asked to rank screens on the basis of “good” design. A significant negative correl...

In this study, a musculoskeletal robot is used as a tool to investigate how animals control their complex body. Sprinting is a challenging task that requires maximizing the potential resources of a musculoskeletal structure. Our approach to robotic sprinting is the Athlete Robot — a musculoskeletal robot with elastic blade feet controlled by feedforward motor command. We use a catapult launcher...

The paper presents a method of determining the dynamic parameters multiple-rocket-launcher system mounted on wheeled vehicle based Newton's law motion. simulation was conducted and then results were compared with corre-sponding experimental data to verify reliability model. model ap-plied in calculation tested out B?-21 (of Rus-sia). theoretical are relatively consistent meas-ured data. depende...
