This week’s accomplishments 1. Experiment Details of the experiment were discussed and the objectives were defined: Figure 1: Visualization of Experiment - A scaled aircraft is placed inside the ARMS wind tunnel connected by a stand that only allows movement in the pitching direction. The aircraft CG can be moved to three different locations (0%, 25% and 50% chord) and the elevator deflection is controlled electronically by the students running the experiment; the aircraft is designed so that it can be trimmed when elevator deflection is within an appropriate range. - Students will explore the effects of CG position and elevator deflection on the stability characteristics of aircraft via trim diagram and pitching motion (AoA vs. time). - Students will be able to observe the correlation between the trim diagram and real aircraft pitching motion (i.e. steeper the trim curve, the faster the a/c will stabilize at the equilibrium angle of attack- AoAe). -
