摘要

This paper introduces a morphing aircraft concept whose purpose is to demonstrate a new bioinspired flight capability: perching. Perching is a maneuver that uses primarily aerodynamics, as opposed to thrust generation, to achieve a vertical or short landing. The flight vehicle that will accomplish this is described herein with particular emphasis on its addition levels of actuation beyond the traditional aircraft control surfaces. The dynamics of this aircraft are examined with respect to changing vehicle configuration and flight condition. The analysis methodologies include an analytical and empirical aerodynamic analysis, trim and stability analyses, and flight simulation. For this study, the aircraft's motions are limited to the longitudinal plane only. Specifically, cruise and the perching maneuver are examined, and comparisons are drawn between maneuvers involving vehicle reconfiguration and those that do not.
