Analysis of vibration of rotors in unmanned aircraft

2014 19th International Conference on Methods and Models in Automation and Robotics (MMAR), 2014
In the paper, solution of the problem of vibrations which appears during the maneuvers of quadrocopters is presented. Those special kinds of vibration aren’t related to mounting or manufacturing faults. In this kinds of flying machines the main sources of vibration comes from motors and/or propellers unbalance. The paper shows analytical description of

Unmanned Cargo Aircraft: From Anywhere to Everywhere

Engineering & Technology Reference, 2012
While unmanned aircraft have been in use for decades, their suitability for transporting cargo is only now slowly being recognised. The first prototypes of unmanned cargo aircraft (UCA) are currently being tested. There are two categories of UCA: short-distance aircraft for delivering packages and specialised items like medicines, and UCA for long ...

Miniaturization and Control of an Unmanned Tiltwing Aircraft

Unmanned Systems, 2023
The objective of this paper is to describe the miniaturization and control of an unmanned tiltwing aircraft. For geometric miniaturization and mechanical realization, a lightweight design based on carbon fiber tubes, polystyrene rigid foam and 3D-printed parts is used.

The Future of Unmanned Aircraft

1986
Recent technological advances such as in securing data links and increasing stealth capability have led to a renewed interest in aircraft which operate without a pilot. There are basically two types of unmanned aircraft. The drone is a vehicle that either follows an entirely preprogrammed trajectory or homes in on a target via a target-seeker.

Wideband Transmission for Unmanned Aircraft Systems

2018 International Conference on Information and Communication Technology Convergence (ICTC), 2018
To design a wideband UAV link, we propose two candidate waveforms, SC-FDMA with windowing and SC-FDE with RRC filtering. Considering UAV channel and operation environments, a unified frame structure for both waveforms is also proposed. Based on the simulation results on transport block error on UAV multipath fading channels, we show that the ...
