Innovative First Year Aerospace Design Course at MIT

Abstract

AbstractStudents at MIT typically take major‐specific courses beginning with their second year of studies. For the first year students eager to begin their aerospace education and to help those students unsure about selecting aerospace engineering as their major field, the MIT Department of Aeronautics and Astronautics offers an elective course, Introduction to Aerospace and Design. The course makes use of the new opportunities offered by the World Wide Web and provides students a real engineering experience through the hands‐on, Lighter‐Than‐Air (LTA) vehicle design project. The course teaches the basic concepts of aeronautics, includes lectures on design, and gives an overview of astronautics. The flexibility inherent in the World Wide Web allows us to accommodate the needs of students who require a review of the fundamentals in addition to in‐ class lecture material and the needs of others who desire to learn advanced material beyond what is presented in lecture. A Web‐based Discussion Forum greatly facilitated interaction among students, resulting in better vehicle designs and a friendlier classroom environment. The course culminates in an LTA vehicle design competition in which teams of five to six students design and build radio‐controlled blimps measuring up to 5 meters in length. The vehicles are flown around the perimeter of a basketball court with the objective of carrying a maximum amount of payload in a minimum amount of time. The students are introduced to real‐world engineering practice through oral presentations of their preliminary designs and critical designs in front of a faculty jury. Towards the end of the course, the students are required to submit a design portfolio showing how their LTA vehicles took shape via their individual and team efforts. The students are permitted to examine previous designs and improve upon them, yielding better vehicles every year. Results from a survey indicated that the freshmen felt much more comfortable working on technical problems with no clear answers as well as designing and building a device from an assortment of given parts.
