The objective of this proposal is to investigate the necessary demonstration activities in order to mature technologies for nuclear electric propulsion (NEP) systems that is considered one of the key enabler to allow deep exploration and science missions both manned and unmanned. The DEMOCRITOS projects aims to define three Demonstrator Concepts in regards to NEP technologies: 1. Detailed preliminary designs of ground experiments that will allow maturing the necessary technologies in the field of MW level nuclear electric propulsion. The project will investigate the interaction of the major subsystems (thermal, power management, propulsion, structures and conversion) with each other and a (simulated) nuclear core providing high power, in the order of several hundred kilowatts. 2. Nuclear reactor cost studies and simulations to provide feedback to the simulated nuclear core of DEMOCRITOS ground experiments as well as conceptualize the concept of nuclear space reactor and outline the specifications for a Core Demonstrator, including an analysis of the regulatory and safety framework that will be necessary for such a demonstration to take place on the ground. 3. System architecture and robotic studies that will investigate in detail the overall design of a high power nuclear spacecraft, together with a pragmatic strategy for assembly in orbit of such a large structure coupled with a nuclear reactor. Additionally, the project partners will define a programmatic plan, insuring that the demonstrators can be built, tested, and reach the established ambitious objectives, this with a clear organization between international partners and with costs shared in a sustainable way. DEMOCRITOS aims to form a cluster around NEP related technologies by organizing an international workshop and invite external stakeholders to propose ideas for the ground and flight demonstrators or possibly join in the effort to realize the ground demonstrator experiments.

Accurate error equations for strapdown interial navigation system (SINS) are derived partly with account of nonideal onboard time scale. Comments are given on specific features of SINS behaviour unnoticed earlier using approximate equations of INS errors. Error equations are first proposed to improve SINS accuracy as well as to analyze it. Limits on SINS accuracy due to quantum noise of Sagnac effect gyros such as laser and fiber-optic gyros and atom interferometers on de Broiglie waves [1] are estimated. © 2014 Pleiades Publishing, Ltd.

Biologically motivated mathematical models, which describe the dynamics of the thrombocytopoietic, granulocytopoietic, and erythropoietic systems in irradiated humans, are thoroughly investigated. These models are the systems of nonlinear ordinary differential equations, whose variables and constant parameters have clear biological meaning. The modeling studies reveal general regularities and peculiarities of the dynamics of the aforementioned hematopoietic lines in acutely and chronically irradiated humans. It is shown that the predictions of the models qualitatively and quantitatively agree with the respective clinical data for humans exposed to acute and chronic irradiation in wide ranges of doses and dose rates. Moreover, the "lethal" dose rate of chronic irradiation, which is evaluated in the framework of the granulocytopoiesis model, coincides with the real minimal dose rate of lethal chronic irradiation for humans. As for the thrombocytopoiesis and erythropoiesis models, the respective "lethal" dose rates of chronic irradiation are very close to the real one for humans. All this bears witness to the validity of employment of the developed models in the investigation and prediction of radiation effects on human hematopoiesis. © 2012 Health Physics Society. Source

The PoLaRBEAR (Production and Analysis Evolution For Lattice Related Barrel Elements Under Operations With Advanced Robustness) project focuses on reliable novel composite aircraft structures based on geodesic technology aiming at a significant higher Robustness and Technology Readiness Level (TRL). While the global structural behavior of composite geodesic structures is investigated and understood in a top-down approach in EU-ALaSCA, PoLaRBEAR will follow up in a bottom-up approach on local level analyzing the geodesic structures in terms of in-operation demands for higher TRL. The main objectives of this research proposal are: Industrial highly automated process for cost efficient barrel manufacturing Advanced reliability of geodesic structures under operational loads Design rules for robust grid structures The aim is to promote a competent cooperation in the development of light, low-cost airframe fuselage structures made with a new generation of composite materials and based on geodesic / iso-grid technologies under operations. The proposal will enhance the cooperation in research and in innovation between the European Union and the Russian Federation in the field of civil transport aircraft.

The main objective of RESEARCH project is the definition of an electrical architecture for Flight Control System capable of controlling a flight control surface on an Aircraft with the help of electrically operated actuators, thus replacing the hydraulic actuators commonly used in current Aircraft designs. This architecture will be designed with the main objective of being electrical, as this is the main purpose of this call, and certifiable, since the intention is to be able to use it in a possible future Aircraft. The objective of the RESEARCH project is to find a robust architecture to meet the constraints imposed by safety regulations while keeping other system performances (as weight, Reliability) as optimal as possible.
