A review of the research accomplished in 2009 in the System-Level Design, Analysis and Simulation Tools (SLDAST) of the NASA's Airspace Systems Program is presented. This research thrust focuses on th....
The vision of SESAR is to integrate and implement new technologies to improve air traffic management (ATM) performance. Enhanced automation and new separation modes characterize the future concept of ....
Accuracy on weather prediction is a significant factor on present models of air traffic and planning, and will be a key factor on future advanced models in many areas and activities, and we can envisi....
Scheduled arriving aircraft demand may exceed airport arrival capacity when there is abnormal weather at an airport. In such situations, Federal Aviation Administration (FAA) institutes ground-delay p....
In 2009, an important aircraft manufacturer committed to the Temporary Business Association between S.A.S. Group S.r.l. and Bertolotti S.p.A. the realization of a military airlift Fuselage Trainer (Fu....
This paper discusses the ground and range operations for a Shuttle derived Heavy-Lift Vehicle being launched from the Kennedy Space Center on the Eastern range. Comparisons will be made between the Sh....
A pressure regulating valve is a type of flow control device that is a combination of a control orifice and a flow compensator. The compensator orifice modulates its opening to regulate the flow rate ....
The main study illustrated in this paper deals with the computation of commands which allow an aircraft to recover a nominal energy trajectory from a low/high energy state during the approach phase. T....
Nonlinear dynamic inversion (DI) has emerged as an area of increased application for flight control law design during recent years. It is well known that the DI control law will cause the open-loop ze....
The paper presents feasibility and effectiveness of an innovative algorithm for spacecraft attitude determination, based on the real time fusion of raw data measurements provided by APS cameras, less ....
Magneto-rhelological(MR) dampers are devices that use rheological fluids to modify the mechanical properties of fluid absorber. The mechanical simplicity, high dynamic range, large force capacity, low....
The paper describes the methodology of contact problem solving that is used in specialized software code aimed at simulation of aircraft assembly process. For considered class of problems it is possib....
Until recently, the electrical systems architecture that connects hardware devices and their accompanying control components were not separately a part of formal certification mandates. This changed w....
As the US is getting ready for the Next Generation (NextGen) of Air Traffic System, there is a growing concern that the current techniques for verification and validation will not be adequate for the ....
Tube Launched-Unmanned Air Vehicles (TL-UAV) are munitions that alter their trajectories during flight to enhance the capabilities by possibly extending range, increasing loiter time through gliding, ....
Critical systems are subject to drastic certification constraints (DO178-B for avionic systems, SIL-4 for railway systems, ISO26262 for the automotive domain), which require system providers to produc....
Lightweight spacecraft components such as reflectors are very sensitive to acoustic loading, and accurate prediction of peak stresses encountered in an acoustic test is critical to a successful design....
Water is a contaminant that can lead to fuel system icing, microbial contamination, corrosion and fuel quantity gauging problems and therefore an efficient water management system is required in order....
In this paper, we introduce the use of ontologies to implement the information developed and organized by resource planning tools into standard project management documents covering integrated cost, r....
