Are You In Control?

Abstract:: This lesson teaches the engineering method for testing wherein one variable is changed while the others are held constant. Students compare the performance of a single paper airplane design while changing the shape, size and position of flaps on the airplane. Students also learn about control surfaces on the tail and wings of an airplane.

Hydrofoils and Propellers, Fall 2003

Abstract:: Theory and design of hydrofoil sections; lifting and thickness problems for sub-cavitating sections, unsteady flow problems. Computer-aided design of low drag, cavitation free sections. Lifting line and lifting surface theory with applications to hydrofoil craft, rudder, and control surface design. Propeller lifting line and lifting surface theory; computer-aided design of wake adapted propellers, unsteady propeller thrust and torque. Flow about axially symmetric bodies and low-aspect ratio lifting surfaces. Hydrodynamic performance and design of waterjets. Experimental projects in the variable pressure water tunnel.

Abstract:: The purpose of this class is to tell you something about our Tech Dinghy and how to sail it. This OCW site is arranged as a series of skills, explained both with lecture notes and videos. Please do not think of these skill checks as tests, but instead, as measures of your understanding of our sport. We don’t expect perfection from our beginners, but only that our members be able to safely handle the boats and themselves on the Charles. For those who wish it, there will be much more that can be learned about other boats and other waters, but what can be learned here will provide the basis to build on. For more detail, a text on sailing the Tech Dinghy is provided in the readings section.

Abstract:: This lesson introduces students to the art of designing an airplane through paper airplane constructions. The goal is that students will learn important aircraft design considerations and how engineers must iterate their designs to achieve success. Students first follow several basic paper airplane models, after which they will then design their own paper airplane. They will also learn how engineers make models to test ideas and designs.

Abstract:: In this design challenge, students learn about the Vikings from an engineering point-of-view. While investigating the history and anatomy of Viking ships, they learn how engineering solutions are shaped by the surrounding environment and availability of resources. Students apply this knowledge to design, build and test their own model Viking ships.
