]{ x} = {F (t )}Let x(0) and x (0) be the initial conditions representing the initial displacement and initialvelocity respectively. Applying the Laplace Transform, the above equation can bewritten as, s 2 [ M ] + s [C ] + [ K ] { x ( s )} = { F ( s )} + s [ M ] + [C ] { x(0)} + [ M ]{ x (0)} Page 12.1252.5For zero initial conditions,{ x(s)} = [ H (s)]{F (s)} ; where the Transfer Function, [ H (s)] = −1 s 2 [ M ] + s [C ] + [ K ]This matrix equation for the transfer function can be

search, acquisition, track andtarget subsystems. In the early 1970’s, the first author was evolved with designing, building andinstalling successful ground based missile locating and tracking systems for the Department ofDefense. Funds for additional ground based missile locating and tracking systems were notallocated because a decision was made to deploy satellite missile defense systems. The 1972Antiballistic Missile (ABM) Treaty with the Soviet Union delayed development of missiledefense systems by the United States (U.S.). Now, the U.S. has a National Missile Defense(NMD) program. The most pressing concern today is the feasibility of an attack by NorthKorean ballistic missiles bearing nuclear or biological weapons. Hypothesizing that a

Generally this course tends to be a broadintroduction to terminology, basic aerodynamics, performance, propulsion and structures. Insome programs, a hands-on project is assigned to the students to make the course moreinteresting and provide

- Table 1 – NASA Program/Project Life Cycle & Related Classes for the Capstone Design Sequence Simulation Concepts In order understand fundamental simulation concepts one needs to have a look at simple numerical integration concepts and their implementation /2/. It is important to visualize that only a first order differential equation of type r r r r s&= f ( s , t ) needs to be solved. s is the state variable and s& is the state derivative, which must be vectors of the same size. This is accomplished in the space systems engineering course using the single step Euler

place to study, and AT308 is no exception to the rule. Upon completion of thiscourse, students have a much better grounding in the theoretical knowledge, which they first hearand see during lectures. They understand heat treatment and different tempers of aviation gradealuminum. They also realize the importance of following heat treatment processes to getconsistent properties of the materials. The well-equipped laboratory provides a place to apply thetheory and develop their skills. It becomes more than just paper knowledge - it is something theycan touch, make, assemble, and test. Experience is the best teacher. This is what studentsexperience during their "employment" in AT308, Inc.References1. Collicott, S. H., Increasing freshmen

retired its A-6E’s and replaced them with F/A-18’s. The transfer was made possible withthe help and support of research sponsors at Naval Air Systems Command Headquarters and atthe Manned Flight Simulator branch of the Naval Air Warfare Center, Patuxent River, Maryland.A diagram of the simulation system can be found in Figure 1. The left (pilot’s) seat of the trainercockpit represents the cockpit of a A-6E Intruder. The right seat has been modified toaccommodate either an instructor or a flight test engineer with a computer driven CRT that canbe custom configured with instrumentation as desired. The simulation computer has beenconverted to a SGI Origin 2000 computer. This allows the simulation of many different aircraftmodels, from a Cessna 152

&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

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. The class originatedwith encouragement from industry
