&D expenses and time, a reduction in toolingand associated costs, a reduction in the number of possible mistakes on the shop floor, as well asan overall reduction in the component cost due to volume purchasing.The compressor component was then quickly identified as a possible candidate for part countreduction. It was chosen due to its overall complexity, time necessary for assembly and service,expensive materials, and overall number of parts. A modular compressor concept was introducedand a preliminary design [on a conceptual level] was conducted to show the possible benefits ofsuch a concept.Background and Literature Survey for the Modular Compressor projectThe original gas turbine modular concept2 was first developed in the early 1960’s

project-based learning that we use is based on problem-based learning. Each project has oneor more problems that need to be solved and often these problems can be broken down to smallerproblems that each team can address. These problems are centered around the goal(s) of eachproject. For example, a competition project may need to build a rocket that exactly reaches 5,280feet. This problem can be broken down to smaller problems such as the size of the motor, weightof the rocket, and other problems that contribute to the goal of obtaining that altitude.The projects we have involve multiple disciplines and multiple problems to be solved. With theexample of the rocket project, we have aerospace, mechanical, chemical, electrical and

In 1948, the wind tunnel was officially named the Kirsten WindTunnel, after the man who had worked so hard to get it built.

Lack of appreciableprogramming experience, particularly in Fortran, means students have to devote considerabletime to resolve common mistakes that cause compilation difficulty, and develop an ability todebug a code to identify and eliminate the source(s) of error. Through consultation with theinstructor and teamwork, students gradually overcome the hurdle and complete the analysis andoptimization programming, which is essential before they can proceed with the fabrication and

ATC and IFF systems are presented to explain theirpurpose and illustrate the substantial overlap in function (ATC is civilian, IFF is military).8The major emphasis in the systems material is on radar, which is used extensively in EWoperations and is perhaps least familiar to the students. The introduction includes radar’spurpose, antenna type(s), continuous wave (CW) vs. pulsed, and monostatic vs. bistatic.6,1,9 Thistopic was initially planned for two lectures, but was stretched to three lectures because thestudents struggled with the material. After the intro, pulsed and CW radars are treatedseparately, including range calculations for pulsed radar and Doppler shift for CW radars.Finally, radar ranging is covered

Thisproject was due on one of the last days of the semester and in order to do it we had to apply allthe knowledge learnt during the course. It is not true that we had no textbook. It was not veryused during the classes. But (the prof) gave us the syllabus the first day of class, and there wereall the topics of the course were related with the corresponding chapters of the book.He is not afraid to give the grades that one deserves.

Southeast, and the U. S. We believe that the addition of the astronautics optionwill increase the potential for our graduates to find positions after graduation. As discussedabove, there has been a renewed emphasis in the U.S. on space exploration, and companies whoare developing the technologies necessary for new space exploration will need engineers trainedin astronautics. There is also continued growth in the area of space utilization fortelecommunications, imaging, weather forecasting, and other fields, and the companies andmanufacturers involved in these areas, such as the design and construction of earth satellites,need engineers trained in astronautics.

Topics covered included: • Familiarity with NI LabView (implemented during the laboratory period) o Taught in four lectures with an application orientation. o Students learned LabView by writing an acquisition code for an ATI 6- component platform type balance. o Teaching approach was minimalistic such that students would need to explore the numerous menu options to find suitable VIs to perform a desired task. Note that a suggested approach to implementing the VI(s) was presented

internet will return a number of university programs that teach spacecraft designwith a variety of approaches: some focus on hands-on hardware experimentation; some aremulti-semester efforts, and some involve academic study of a spacecraft design. The Universityof Colorado’s program falls into the latter. With the growing interest in teaching systemsengineering as part of the engineering curriculum, teaching spacecraft design provides a richopportunity to stress systems engineering approaches to problem solving within a definedcontext.Within the University of Colorado’s Aerospace Engineering curriculum, ASEN 4148/5148Spacecraft Design has been taught as a one semester class since the 1980’s.

/C planes, flies subsonic at very low Reynolds numbers. Anotherconsideration is thickness to chord ratio. While thicker wings have more drag, thicker wingsoffer advantages in other areas.5 The added volume gives space for fuel storage, structural load-bearing members, electronics, and control mechanisms. After scouring books for airfoils, the S8036 airfoil was selected because of its gradualdrag polar. According to Lyon, at Reynolds Number 400,000, the S8036's drag coefficient doesnot increase noticeably with the lift coefficient until a very extreme lift coefficient is achieved.7This relationship is ideal because the UAV operates over a range of velocities, and is, therefore,conducive to a slight, gradual change in drag with lift
