semestersof calculus, and during their high-school studies they must have already studied particlekinematics and dynamics. Simulation software and computer algebra systems allow students toexperiment with phenomena which are too complex to calculate or too expensive to bereproduced in a laboratory, or are simply not accessible to the senses. A computer algebra systemis essentially the ability to manipulate concepts, using computer expressions, which aresymbolic, algebraic and not limited to numerical evaluation. A computer algebra systems canperform many of the mathematical techniques which are part and parcel of a traditional physicscourse. The successful use of computer algebra systems does not imply that the mathematicalskills are no longer at a
project). Withinthis environment for the PID study, a predefined GPS coordinate path may be implemented asthe desired flight path, or what is called a Virtual Leader. From this a follower aircraft, which isrepresented by the derived nonlinear aircraft model, tries to stay with the Virtual Leader on itsflight path. This simulation environment also allows for the control system to autonomouslyinject maneuvers on the control surfaces during the simulation, similar to those performed inactual flight. This simulation also has a three-dimensional visualization environment, (using theSimulink 3D Animation® tool), which visually represents the YF-22 aircraft behavior. Figure 13shows a sample from a flight simulation of this environment
was heavily incorporated in each aspect of the class which made amonumental difference in the students’ understanding of the subject. The scaffolding of the classstructure and the open-ended homework assignments helped students to acquire multiple technicalskillsets in experimental and computational aerodynamics. Some of the skillsets include designingairfoil using Joukowski transformation, performing inviscid flow simulation using panel methods onthe airfoil, 3D printing the airfoil and testing it in the wind tunnel, numerically determining vorticityand circulation of wingtip vortex, leading edge vortex, etc. Through the passion project componentof the class, students were able to perform experiments on plethora of applications of
