Abstract

Innovative Instruction for Undergraduate Aircraft Dynamics and ControlIntroductionPrior studies have shown that the conventional teaching methods in university engineeringcourses undermine students’ motivation to persist in pursuing an engineering career [1-3]. Thisstudy, supported by NASA’s E.2 Innovation in Aeronautics Instruction conducted at a largesouthwestern university, addresses the development of an innovative approach to teachingfundamental concepts in Aircraft Dynamics and Control (ADC) to promote student motivation.A pilot study conducted in the same university identified that students reported significantlylower self-efficacy and perceived instrumentality in junior-level courses ([4]). The proposedapproach utilizes modern simulation technologies to teach fundamental concepts in ADC. Thepaper will describe the software development process, the instructional development process,and the instructional tool which has been developed, integrating the CAD package, DATCOMand the flight simulator. The paper will also describe the effect of the changes in instruction onstudents’ learning and motivation.Brief DescriptionThe topics in ADC consist of aircraft static stability, trim, dynamic modes, response to controlinputs and simple aircraft closed‐loop controllers. From the instructor’s experiences, thechallenges faced by students in appreciating the course is the inability to visualize complicated,multi‐modal aircraft motions and connect the material learned in ADC to content from otherAerodynamics courses. To overcome this challenge, a curriculum that utilizes the USAFDATCOM [5] and commercially available flight simulators in combination with Matlab wasdeveloped to enhance the student’s learning experience.The most significant challenge in this project was the full inclusion of the simulation software inall educational activities to emphasize the importance of visualization of multi-modal aircraftmotions for understanding principals discussed in ADC. In the paper we will describe in detailthe assignment development process and provide examples of the types of assignments whichfully integrated the simulator meaningfully into the ADC curriculum. One example we willprovide: Students were asked to input a particular initial condition into the software that excitedone of the dynamic modes of the aircraft motion. Students recorded their observations from theflight simulator and concluded that the mode that was excited was the Dutch-roll mode. Then,with the mathematical model of the aircraft, the students performed eigenvector analysis toverify that it was initial conditions that resulted in the Dutch-roll mode excitation.To evaluate the success of the innovative design students’ perceptions of the course and theirmotivational beliefs were examined in two semesters, the first semester when the instructortaught using traditional methods (n=40) and during the second semester, in which the sameinstructor taught using the innovative design (n=18). The surveys used in this evaluation werewell-established scales that have generated valid and reliable responses from students [6].ConclusionCompared with students in traditional instruction students in the innovative course reportedstatistically significantly higher confidence in their ability to learn course materials, engagedmore in active learning strategies, and performed better on an identical final exam. Continuedresearch is being conducted to evaluate the most successful assignments.References[1] Guzdial, M., Ludovice, P., Realff, M., Morley, T., Carroll, K., et al., "The challenge ofcollaborative learning in engineering and math", presented at Frontiers in Education Conference,2001. 31st Annual, NY, 2001.[2] Kalonji, G., "Capturing the imagination: High-priority reforms for engineering education." inEducating the engineer of 2020: Adapting engineering education to the new century.Washington,DC: National Academics Press, 2005, pp. 146-450.[3] Seymour, E. and Hewitt, M.
