Background
By exploring unconventional ways of flight, deviating from airplane standards that have not changed much over the years, we seek for different innovation. One of this is through a Lie Bracket maneuver which composes of a series of movements in order to produce another one. For our project, we seek to verify that by pitching and rolling the plane at a high angle of attack near stall. Through the use of the aileron and elevator moving simultaneously out of phase, this will produce a slight rolling moment that is higher than having the aileron fixed at its highest angle.
Goal and Objectives
Having started this project in Spring Quarter 2018, the main goal is to experimentally verify that at high angles of attack, the Lie Bracket Maneuver with the aileron and elevator will indeed produce a slight rolling moment.

Our current goals is to: modify a pre-existing small-sized airplane model to withstand wind tunnel conditions, design and manufacture a unique airplane mechanism through the use of gears and a motor to drive the aileron and elevator out of phase with oscillatory motion, and design and manufacture a unique mount that allows three degrees of freedom of vertical motion, pitch, and roll.

Innovation
The Lie Bracket maneuever has not been tested on an airplane yet, so by doing an experimental verification on a smaller-sized model airplane, designing a unique mount and unique mechanism to experimentally verify this phenomena will be great progress towards unconventional flight dynamics.
The Bigger Picture
If the Lie Bracket maneuver of elevator and aileron does indeed produce a slight rolling moment larger than having the aileron fixed at an angle, then this opens a new world of unconventional flight with combinations of various controls that may allow for new methods of stability.

Initial Project Information

  • Project ID#

    MAE0177

  • Course Code

    19273

  • Project Type

    Research

  • Field of Interest

    Flight Dynamics and Control, Wind Tunnel Testing, Aerodynamics, Mechanical Design and Manufacturing

  • Description

    We are trying to verify unconventional ways to execute specific maneuvers through nonlinear (Lie bracket) control actions. For this quarter, we are trying to verify an unconventional roll mechanism that has been theoretically proved to be more effective than the conventional roll mechanism at high-angle-of-attack maneuvers.
