  • Space shuttle main propulsion system anomaly detection: A case study

    Page(s): 4 - 13

    The space shuttle main engine (SSME) is part of the Main Propulsion System (MPS) which is an extremely complex system containing several sub-systems and components, each of which must work precisely in order to achieve a successful mission. A critical component under study is the flow control valve (FCY) which controls the pressure of the gaseous hydrogen between the SSME and the external fuel tank. The FCV has received added attention since a Space Shuttle Mission in November 2008, where it was discovered during the mission that an anomaly had occurred in one of the three FCV's. Subsequent inspection revealed that one FCV cracked during ascent. This type of fault is of high criticality because it can lead to potentially catastrophic gaseous hydrogen leakage. A supervised learning method known as Virtual Sensors (VS), and an unsupervised learning method known as the Inductive Monitoring System (IMS) were used to detect anomalies related to the FCV in the MPS. Both algorithms identify the time of the anomaly in a multi-dimensional time series of temperatures, pressures, and control signals related to the FCV. This discovery corroborates the results of the inspection and also reveals the time at which the anomaly likely occurred. The methods were applied to data obtained from the March 2009 launch of Space Shuttle Discovery to determine whether an anomaly occurred in the same sub-system. According to our models, the FCV sub-system showed nominal behavior during ascent. View full abstract»

  • Navigation device prototype model construction

    Page(s): 14 - 17
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (565 KB)  

    The basic technical characteristics of the navigation device, realized on the basis of a strapdown inertial unit, satellite navigation equipment, and a computing device of a new generation on the basis of the “Malakhit-7” digital computing system are described. Preliminary estimates of operational and precision characteristics of the navigation device components with the use of the corresponding mathematical model and a number of test benches of the Federal State Unitary Enterprise (FSUE) “Scientific and Production Association of Automatics” (`SPA of Automatics') are received.

  • Logistics support system: Harmonization enhances Multi-National Support

    Page(s): 18 - 21

    This examines the evolution of the Harmonization approach for the LM-STAR® Multi-National Support. Critical to the Lockheed Martin Corporation's approach to winning the JSF/F35 contract in 2002 was developing a common logistics approach. A strategy was devised for ATE Harmonization whereas all Original Equipment Manufacturers (OEMs) would utilize a common ATE subset solution knowing one day programs developed on the subset solution would be required to execute on a full-up solution for Depot support, etc. Lockheed Martin Simulation, Training & Support (LMSTS) was already executing the Consolidated Automated Support System (CASS) and some of its early PBL efforts, Contractor Logistic Support (CLS) efforts, and the Consolidated Service Pool Program (CSP) and realized how a common solution was beneficial to the US Navy and other foreign military users of CASS. A test envelope was established using the CASS as a baseline. Several OEM/supplier meetings were held and the test envelope was expanded to handle additional OEM test requirements. The first station built was a full-up superstation with the entire test envelope supported. From this point, each OEM working with their Lockheed Martin Aerospace buyer, filled out requirements needs, as well as a quantity and need date. From these requirements LMSTS developed various configurations and delivered 62 System Design & Development (SDD) testers to OEMs in the United States, United Kingdom, and other JSF partnering countries. LMSTS is now delivering 16 more LM-STARs® in Low Rate Initial Production (LRIP), 3 to the OEMs and in LRIP4 LMSTS will deliver 21 stations to OEMS and three to the Depot. View full abstract»

  • Tobyhanna army depot Automated Test System modernization

    During the last four decades the number of Automated Test Systems (ATS) has experienced tremendous growth at Tobyhanna Army Depot (TYAD). This is characterized in the proliferation through Base Realignment and Closure acquisition and in-house development of a wide variety of general and special-purpose ATS - to date, there are 94 unique ATS and a total of 230 ATS. With advancing technology and increasingly complex electronic systems, unique ATS has become a problem of maintenance test strategies at the depot; given the high costs of modernizing or replacing ATS and its potential effect on meeting mission success requirements. The aging testers at TYAD are becoming increasingly out-of-date and more difficult to support. When the testers do not work properly, maintenance can suffer and mission readiness can be adversely affected. This will analyze the problem and present a plan for modernization of ATS at TYAD that satisfies Army Regulation, AR750-43, and DoD ATS acquisition policy. View full abstract»

  • Systems engineering approach for high speed enterprise systems

    Page(s): 27 - 33
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1387 KB)  

    Disparate customer support centers in an enterprise system apply different monitoring and analysis tools while attempting to ensure quality of service for the end-user. These tools provide inconsistent metrics that make problem resolution inefficient and reactive rather than proactive and effective. A systems engineering approach is proposed that considers enterprise monitoring and analysis in high-speed enterprise communications systems done by support centers via collaboration rather than in isolation. This presents graphical representations of various aspects of the monitoring and analysis approach that include architectural, operational, systems-level, and technical views. For each of these views we identify the applicable system components and the integration of these components that enable solution of system-wide problems. View full abstract»

  • Naval multi-function radar

    The missions expected to be covered by Naval Multi-Function radar (MFR) have increased significantly these last decades. The main evolution of these systems, from a design point of view, have two origins, one the Tactical Picture Compilation (TPC), the other the extension of the warfare domain of weapon systems connected to MFR. As far as TPC is concerned, Long Range coverage and proximity of littoral, have been the major requirements impacting the design of naval MFR. This discusses the principal features of typical architecture for modern Naval Multi-Function radar, and how the requested new missions impact the design. View full abstract»
