diesel,biodiesel, alcohols and vegetable oils have been tested in compression ignition engines in detail.There is some work done in the literature regarding the operation of micro gas turbines withalternative fuels such as biodiesel and straight vegetable oils [1-4]. Because vegetable oils have ahigh viscosity, they cannot be used in gas turbines without fuel modification. Such modificationcan be done by preheating vegetable oils to the point where the viscosity is comparable to dieselfuel in order to achieve good fuel atomization, which affects combustion and emissioncharacteristics. Although biodiesel has a lower viscosity than vegetable oils, it is still moreviscous than diesel. Thus, some fuel preheat is needed in order to achieve

There have been numerous efforts in variousdisciplines where college and university professors have been challenged to develop instructionalmethods that transform students from passive listeners to active learners [1]. In the author’sexperience, introducing such techniques in a highly conceptual and mathematically intensiveaerospace class is ‘easier said than done.’Active learning is in short, anything that students do in a classroom other than merely passivelylistening to an instructor’s lecture. This includes everything from listening practices which helpstudents to absorb what they hear, to short writing exercises in which students

In fact,these systems are complex because of their challenging objectives: aircraft and spacecraft musttransport people, cargo and time-sensitive data through extreme environments and do so withvery high reliability. Simple solutions are often insufficient, and yet the complex

This aircraft hasa large degree of anhedral clearly visible from most angles but especially from the front view.Since this particular aircraft is fairly well-known, the instructor might choose to present itunlabeled in the middle of the lesson, hyping students up with a small reward to whoevercorrectly identifies the aircraft first

understanding the kinds of iteration that occur and why they occur; implementing and assessing the strategy will be a focus of future work. 1. Introduction and Motivation Spacecraft design is highly iterative. Like many complex systems, problems faced during thedesign of a spacecraft often have more than one solution. The fact that an operable space systemcapable of meeting mission requirements within imposed constraints including (but not restrictedto) mass, cost, and schedule makes spacecraft design a highly iterative process of exploringoptimal solutions that have conflicting requirements. Therefore, systems thinking and iterativedesign practice are important aspects in the development of space vehicles and space systemsthat involve
