This article shows development of a fixed wing Unmanned Aerial Vechicle (UAV) prototype with multi rotor control system. This model pretends increase flight time of multi rotor system using aerodynamic characteristics. The lift force generated by a wing reduce the required power of the motors to raise up the structure during horizontal forward flight. For airfoil selection and sizing of the wing,...
The concept of utilizing the Coandia effect to produce stable flight in saucer type Aerial Vehicles (AV) was first conceived in 1935 by Henri Marie Coanda. Coanda's proposed AV design remained a relatively unexplored curiosity for decades until the recent surge in popularity of small Unmanned Aerial Vehicles (UAV) revitalized interest in the topic. Coandä effect UAV offer some distinct advantages...
Inspired by flying squirrels, we put forward a novel air posture adjustment manner, the wave gliding gait (WGG) model based on flexible menmbrance deformation driven by the high frequency and low amplitude locomotion of limbs. Firstly, we extract the WGG model according to the analysis of the flying squirrel's gliding posture adjustment characteristics. Then, the concept prototype of the WGG model...
Change from a resting state to a full launch on any device that has the characteristic of flight and vertical landing is a major challenge when the control system must be designed. In this sense, there are different effects that alter its dynamics. In this paper, an experimental method based on pseudo-random bit signals (PRBS) is proposed to identify the transfer function of a vertical take-off and...
In order to improve the control loading fidelity of helicopter flight simulator force-feeling simulation system, this paper develops the principle prototype of force-feeling simulation system, establishes the electro-motive force servo loading system model, applies the model to the force-feeling simulation system principle prototype and conducts the test of sense of force. The results show that the...
This paper discusses the improvement of the simulation model and the development of the new mechanism for flight control of a flying robot with the cyclogyro wing. In past study, we focused high maneuverability of the flying robots with the cyclogyro wing, whose rotor had rotation along horizontal axis, and developed some prototypes. The simulation model was also constructed based on the pressure...
To study characteristics of a air propeller-gear reducer propulsion device, a scale virtual prototype of the device was established using ADAMS and Pro/E software based on virtual prototyping and parametric modeling. Kinematics and dynamics characteristics were gained through computer simulation in rated-load and in no-load. The influence of elastic coupling for propeller movement and gear meshing...
We propose a new structure for a permanent-magnet-biased axial hybrid magnetic bearing. Starting with the inner air gap and the outer air gap of conventional axial magnetic bearings, we first construct a novel air gap between the permanent magnet and the outer housing, which we call the second air gap, separating the bias flux paths from the control flux paths. As a result, the control flux paths...
This paper presents the development of a novel air-gliding (hovering) ldquoskateboardrdquo (or ldquoskim-boardrdquo) which operates based on an aerodynamic principle that distributes airflow uniformly between the board and a flat surface to provide an effective air-bearing for air-gliding. Experiments were parametrically conducted to understand the aerodynamic hovering principle as well as to characterize...
