SACD's Support of the Hyper-X Program

NASA s highly successful Hyper-X program demonstrated numerous hypersonic air-breathing vehicle related technologies including scramjet performance, advanced materials and hot structures, GN&C, and integrated vehicle performance resulting in, for the first time ever, acceleration of a vehicle powered by a scramjet engine. The Systems Analysis and Concepts Directorate (SACD) at NASA s Langley Research Center played a major role in the integrated team providing critical support, analysis, and leadership to the Hyper-X Program throughout the program s entire life and were key to its ultimate success. Engineers in SACD s Vehicle Analysis Branch (VAB) were involved in all stages and aspects of the program, from conceptual design prior to contract award, through preliminary design and hardware development, and in to, during, and after each of the three flights. Working closely with other engineers at Langley and Dryden, as well as industry partners, roughly 20 members of SACD were involved throughout the evolution of the Hyper-X program in nearly all disciplines, including lead roles in several areas. Engineers from VAB led the aerodynamic database development, the propulsion database development, and the stage separation analysis and database development effort. Others played major roles in structures, aerothermal, GN&C, trajectory analysis and flight simulation, as well as providing CFD support for aerodynamic, propulsion, and aerothermal analysis

Control system design for a C-130 Ro-Ro sensor deployment platform

A WVU team of engineers designed and built a palletized system that will be used to deploy surveillance sensors from a C-130 cargo airplane. There will be two pallets, one that will house the Operator Station and one that will carry a mechanical arm with a Sensor Pod, where the sensors will reside. This pallet will be placed on the C-130 rear door, which will be opened while in flight. The mechanical arm is designed to rotate the Sensor Pod underneath the door so the sensors can observe the ground.;Computer/Electrical engineers were asked to design the control circuit for the Sensor Pallet, providing the user with a user interface to control deployment of the mechanical arm and Sensor Pod. The mechanical arm should also be deployable in an automated process, controlled by a computerized system. They were also responsible for designing the circuit to provide power to the system, interfacing with the power generated on the C-130 cargo airplane.;The thesis Control System Design for a C-130 Ro-Ro Sensor Deployment Platform details the power distribution circuit design, the control circuit design and the design of the automated process program

A Designed System for Providing Solutions to Basic Engineering Problems

Engineering and the manner in which engineers think is largely visual and functional, and yet engineers are typically provided with a lot of other basic engineering problems to be solved and applied to complex ones. This paper present a designed software for providing solutions to some basic engineering problems. C++ programming language was used in writing the codes. The paper explains the activities involved in C++program development and touched areas such as the general concept of programming, programming languages, compilation and interpretation, storage and execution, functional lines to which computer programs maybe categorized. Several engineering problems and their various real-world applications were considered to accomplish the aim of the work. The problem requirements were properly understood, and the program adequately developed using the Dev-C++ software. The program was coded in a modular fashion, and constructed in a manner that can be fairly understood. Algorithms and flow charts for the basic engineering problems considered were obtained and using formula translation, solutions to such issues were dynamically programmed using the Dev C++ software. The results from the developed software when compared with other methods such as numerical and approximate analytical solutions were observed to be the same. The developed software is however, more user friendly and can be implemented at A Level Higher Institutions, as well as have many other real-world applications.

A decomposition-based approach to uncertainty analysis of feed-forward multicomponent systems

To support effective decision making, engineers should comprehend and manage various uncertainties throughout the design process. Unfortunately, in today's modern systems, uncertainty analysis can become cumbersome and computationally intractable for one individual or group to manage. This is particularly true for systems comprised of a large number of components. In many cases, these components may be developed by different groups and even run on different computational platforms. This paper proposes an approach for decomposing the uncertainty analysis task among the various components comprising a feed-forward system and synthesizing the local uncertainty analyses into a system uncertainty analysis. Our proposed decomposition-based multicomponent uncertainty analysis approach is shown to be provably convergent in distribution under certain conditions. The proposed method is illustrated on quantification of uncertainty for a multidisciplinary gas turbine system and is compared to a traditional system-level Monte Carlo uncertainty analysis approach.SUTD-MIT International Design CentreUnited States.

TT race data logger

This report is made to accomplish the demand from TriCAT Racing motor race team. They suggest if it was possible to create a device capable to log data from a motorbike during a race or testing seasons, mentioning some other similar systems out on the market, but is really expensive. Taking an initial idea, we thought about one way to design a system capable of satisfy the demand of our contractor, trying to reduce costs on the design. At this point we accept the project offered by TriCAT racing team. Known the several issues that they have about the design and studying the different ways to make it, the design is starting to be thought. The contractor needs that the system has to be capable of store the data into a SD card, this data are: position, velocity, RPM, cornering angle and lap time of a motorbike in a circuit race. For solve this issues we thought about microprocessors, GPS’s, and other kind of possibilities, arriving to one possible solution. Now the solution of design question is solved, it is possible to design a system capable to accomplish the demands of the contractor, with a microcontroller PIC18F4550 and a GPS Unit, one Accelerometer, and programming a complex program on C for microcontrollers it is possible arrive to a solution. When we start to build the first prototype and we decide to test it a problem appears, not enough space in ROM memory. During the implementation part, we arrived the conclusion that we made an error choosing the microprocessor PIC18F4550, this error is because the ROM memory. The program that we are using is too big, and the ROM memory of the microprocessor PIC18F4550 it’s not enough to contain all the program. As a result of the short time disposed for make the project, and the errors made at the end, it is not possible to change the design, the prototype is build and we are trying to make it run. If the project could be continued for another students or another engineers, the best idea for start, is change the microcontroller for another with the minimum resources needed by the C program

4 dof scada-based robotic arm for education in engineering / Braço robótico de 4 dof scada para educação em engenharia

 Robotic Arm has become a large potential tool to teach engineering disciplines in automation control courses. In fact, over the past decades, industrial tasks increasingly rely on robots in a wide range of applications in order to handle tasks that could be difficult and hazardous to human beings. The expanding implementation of supervisory control and robotics systems requires engineers with expertise in electrical design, instrumentation, mechanical design and computer programming for a large number of automation systems. This paper introduces a complete Visual C# and SCADA based software for control, monitoring and simulation of a 4-DOF robotic arm for material handling applications. To further this goal a prototype has been created in a CNC machine and a microcontroller 18F4550 board has been connected to an industrial supervisory. The main context of this study is described as an important tool both to motivate students and to serve as the practical use in industrial simulations. Furthermore, not only can the students program and implement microcontroller software, but students teams can also create a multi-disciplinary hands-on skills ranging from basic concepts of kinematics to design manufacturing plants. 

A free interactive matching program

For physicists and engineers involved in the design and analysis of beamlines (transfer lines or insertions) the lattice function matching problem is central and can be time-consuming because it involves constrained nonlinear optimization. For such problems convergence can be difficult to obtain in general without expert human intervention. Over the years, powerful codes have been developed to assist beamline designers. The canonical example is MAD (Methodical Accelerator Design) developed at CERN by Christophe Iselin. MAD, through a specialized command language, allows one to solve a wide variety of problems, including matching problems. Although in principle, the MAD command interpreter can be run interactively, in practice the solution of a matching problem involves a sequence of independent trial runs. Unfortunately, but perhaps not surprisingly, there still exists relatively few tools exploiting the resources offered by modern environments to assist lattice designer with this routine and repetitive task. In this paper, we describe a fully interactive lattice matching program, written in C++ and assembled using freely available software components. An important feature of the code is that the evolution of the lattice functions during the nonlinear iterative process can be graphically monitored in real time; the user can dynamically interrupt the iterations at will to introduce new variables, freeze existing ones into their current state and/or modify constraints. The program runs under both UNIX and Windows NT

Critical Success Factors for Reskilling and Upskilling Engineer Leaders in Customized Executive Education Programs

AbstractSparse research on customized executive education programs leaves a gap in the extant literature on the critical success factors needed for reskilling and upskilling engineers in leadership development. The purpose of this qualitative multiple case study was to describe executive education program experts’ views on the critical success factors needed in customized executive education programs for reskilling and upskilling engineers in leadership development. To meet this study\u27s purpose, a multiple case study design was used to collect data from a purposeful sample of 11 executive education program experts. Semistructured interviews, archival data, and reflective field notes supported the trustworthiness of the study’s findings through data triangulation. Three conceptual models framed this study: Rottmann et al.’s concept of engineering leadership, Fung’s concept of reskilling and upskilling the workforce, and Retana and Rodriguez-Lluesma’s concept of customized executive programs. The data analysis gleaned 20 themes from the five coding categories: (a) customized executive education in the postpandemic era, (b) cocreation of academic–corporate partnership for customized executive education programs, (c) academic–corporate partnership goals for engineer leadership education, (d) critical success factors for a customized executive education program for engineers, and (e) critical success factors for academic–corporate collaborations for reskilling and upskilling engineer leaders. This study contributes to positive social change by identifying the critical success factors for reskilling and upskilling engineers in leadership development to support their midcareer transitions and ensure livelihoods amidst disruptive global events
