Abstract

Modeling of parasitic effects in multi-rotor hybrid aircrafts (Part-II)

Highlights

  • IntroductionAircraft (Zhang and Brandt, 1999), the multiple rotor-propeller sets produce complicated dynamic effects during hover as well as during maneuvers like roll, pitch and yaw

  • This article presents the detailed modeling and analysis of some of the parasitic effects that slink into the dynamics of multi-rotor hybrid aircrafts during transient and steady state flight conditions

  • The objective of our research is to develop a vertically take off and land (VTOL) based hybrid aircraft (Zhang and Brandt, 1999), the multiple rotor-propeller sets produce complicated dynamic effects during hover as well as during maneuvers like roll, pitch and yaw

Summary

Introduction

Aircraft (Zhang and Brandt, 1999), the multiple rotor-propeller sets produce complicated dynamic effects during hover as well as during maneuvers like roll, pitch and yaw These effects result in the nonlinearities in the dynamics of the craft as well as introducing cross coupling in the dynamics (Johnson, 2012). Part-I (Haider et al, 2016) covered the detailed analysis of the parasitic precession moments and the gyroscopic moments This part-II covers modeling of the parasitic effects that are generated in the T-Copter hybrid aircraft, during its typical maneuvers, including air drag moments, tilt reaction moment, angular acceleration effects, reaction moments and frictional moments.
