The logic behind each suggestion and/or question is discussed by the TAs in a way that motivates the students to follow the same logic in solving a problem. Conclusions and interpretations of the results obtained for each problem are presented such that the Page 11.179.3 objective of the problem becomes clearer. 2 B- Extra credit and/or bonus

Case A: Traditional classroom style of teaching using Power Point slides, and white / blackboard is employed. The instructor does most of the talking and students listen passively. At the end of the study, students take a quiz. Case B: The instructor uses props to describe different concepts. Students listen, are encouraged to ask questions, and see and touch the model (prop) and then take the test at the end of the lecture. Case C: The

For several years now, the author has offered courses in aerospace engineering and twoof them are core theory-based courses, which need to be taken by every student in the program.At large, the material presented in these courses is foundational and has very limited variations.To facilitate the students to review the
tools such as MATLAB for design and analysis of control systems. To provide an overview of concepts of design and control in the time domain and control of nonlinear systems. To provide students with the ability to use modern simulation tools such as SIMULINK and LabView for design and analysis of control systems.Course and Project AssessmentsThe course is assessed using formative and summative assessments in the form of homework,quizzes, tests/finals, term project, project report and presentation. Tests, homework andquizzes will assess ABET outcomes a, b, c, h, j and k. Project/Term Paper, report andoral presentations will assess ABET outcomes d, g, i, and k. The framework based on Criterion3 of ABET [8] is outlined below
questions, three map to the environment. Gendered effects of performance in CS areinfluenced by the social environment, whereas programming experience in high school or undergraduateeducation beyond introductory CS is reflective of the opportunity that students have in their pre-collegeenvironment. We also take students’ grades in the linear algebra course to be reflective of theirenvironment, rather than their ability, because the programming assignment we study involved forming anAx = b matrix from a set of equations. Based on students’ difficulty with this concept in class, wehypothesized that having prior knowledge of linear algebra would be helpful on this programmingassignment. And therefore, students who had the opportunity to take advanced
used for both GCScommunication and control commands from the RaspberryPI, but this would require sending theRaspberryPI commands through the GCS computer, as well as the responses to queries of UAVflight mode and altitude. This method was not used because of the increased lag and unnecessarycomplexity this would introduce to the system.System Components Raspberry PI 3 Model B+ Figure 1 - RaspberryPI Model3 B+ The RaspberryPI Model3 B+ is a microcomputer based on the Cortex-A53 (ARMv8-A) 64-bit instruction set [3]. It features the Broadcom BCM2837BO quad-core processor at 1.4 GHz. It is equipped with 1GB of LPDDR2 SDRAM, a 2.4GHz and 5GHz IEEE 802.11.b/g/n/ac wireless LAN, a
) internally wetted, (b) externally wetted, and (c) porous tipFor commercially developed thrusters or those specifically designed for flight purposes, a largenumber of emitter tips in as small an area as possible is desirable to maximize thrust density. Inthese cases, microelectromechanical systems (MEMS) manufacturing techniques are beingemployed in general, with emitter tip densities up to 1600/cm2 [9]. However, it is possible toconstruct a fully functional electrospray thruster using much larger emitters that do not requireMEMS manufacturing. One of the simpler methods is to use standard blunt tip syringe needles asinternally wetted emitters.The emitted particles accelerate through small holes in the

Teams were asked on the first day to sign a TeamPolicies and Expectations Contract to select leadership roles on the team: Coordinator, Recorder,Monitor, or Checker. Each designated role came with responsibilities. This also was not popular.For the most part, students felt the course met their expectations and they felt confident in theirunderstanding of airplanes. They stated the material was presented at the appropriate level. Table 1 – General Questions a. The course met my expectations. 4.32 b. I feel confident in my understanding of 4.06 Aeronautics. c.

It is reasonable to assume that the remaining time (1.23 seconds) was due to that brief observation. There were 19 other team launches using A8-3 engine. Not all results were as close as the ones reported from this student team report.AVION FLIGHT 25 :Rocket: Avion Engine: B6-4 The model weight: 28.46 g (heavier than most due to optionalspray paint used).

The costs could be further reduced by using cheaper load cells with smallerforce ratings.Bibliography1. Barlow, J. B., Rae, Jr., W.

In the program the Euler angle pitch rate is integrated to getpitch angle. But students are introduced to the quaternion method used in full flight simulatorswhich avoids the singularity at 90 degrees of pitch. Please see Appendix A for an example of astudent written program. In contrast, the flight model in the EFS is “industrial strength”.2 Use of Engineering Flight SimulatorThe Parks College Engineering Flight Simulator is used in a variety of ways a) to give AE students some “flight” experience, albeit simulated flight b) to provide a platform on which AE

some students have very good grasp of these principles,majority of the class have trouble in application of these concepts. The computation oftransfer functions in analytical form requires the knowledge of partial fractions andLaplace Transforms. Manual computation of transfer functions is rather laborious foreven some simple systems. MATLAB software can be easily used for this purpose and itis efficient in applying Laplace Transform in order to find the transfer function.Rules for Modeling 1.

The program is part of the School of Aviation andTransportation Technology in the Polytechnic Institute located on the main campus in WestLafayette, Indiana. On the approved plans of study for students, this junior-level course isrequired for a bachelor’s degree program in aeronautical engineering technology. Twoprerequisite courses build the foundational knowledge that is used in this course. The firstprerequisite course is an introduction to reciprocating engines and the second is basic aircraftelectricity.The undergraduate course is currently mapped to two student outcomes for Criterion 3: (b) anability to apply a knowledge of mathematics, science, engineering, and

A set of engineering drawings was prepared in the draftingworkbench (Appendix B), and the DXF file was imported in SurfCam software, which ran theCNC vertical mill to fabricate the form blocks.
