Sound and Safe
This book traces the full history of noise in and around cars, shows how we created auditory privacy in our cars, even though they were highly noisy things at the beginning of the twentieth century. It is about the sounds of car engines, tires, wipers, blinkers, warning signals, in-car audio systems and, ultimately, about how we became used to listen while driving.
Fans
This textbook combines in a unique concept the design and construction of radial and axial fans with the problem of noise generation as well as its mitigation already in the fan development stage. The aim is to describe selected, easily applicable methods of aerodynamic design and noise prediction and to demonstrate their physical principles. Exercises with solutions facilitate understanding. The completely revised and expanded edition now also includes guidance on selecting fans for a given task, simulation-based optimization methods for fan design, and psychoacoustic methods that can be used to measure the quality of fan noise. This book is a translation of the original German 4th edition ...
Sensors and GPS for Drones and Quadcopters
Since the beginning, the development of quadcopters and drones has been strongly influenced by sensors in combination with microprocessors. These flight systems would not be feasible without sensors, because gyros, acceleration sensors and inertial measurement units, for example, are absolutely necessary to make them fly. These are used for axis control. Others, such as the electronic compass, the air pressure sensor or GPS, make control considerably easier for the pilot. Together with sophisticated software, additional sensors such as ultrasonic, infrared or cameras allow additional functions such as automated take-offs and landings, obstacle detection or object tracing. All these sensors and their physical principles are explained in this booklet and their use and possibilities in quadrocopters and drones are discussed.
Green Aviation
Green Aviation is the first authoritative overview of both engineering and operational measures to mitigate the environmental impact of aviation. It addresses the current status of measures to reduce the environmental impact of air travel. The chapters cover such items as: Engineering and technology-related subjects (aerodynamics, engines, fuels, structures, etc.), Operations (air traffic management and infrastructure) Policy and regulatory aspects regarding atmospheric and noise pollution. With contributions from leading experts, this volume is intended to be a valuable addition, and useful resource, for aerospace manufacturers and suppliers, governmental and industrial aerospace research establishments, airline and aviation industries, university engineering and science departments, and industry analysts, consultants, and researchers.
Design Ideas for Drones, Multicopters and Quadcopters
All in all, quadcopters would be much better accepted among model-makers if they were a little more colorful. Many pilots say, however, that all the work building a depron body would be destroyed in a rollover. However, anyone who flies quadcopters today notices that the technology has advanced so far and so safely that (semi-)scale models can be built without problems in this regard. The only problem that arises is that there are not as many flying originals. This booklet provides design ideas for quadcopters, drones and multicopters in general.

Brushless Motors and Controllers
In recent years, brushless DC motors and controllers have begun an unparalleled triumph in model construction and in all technical fields. This book is intended to show how a brushless motor works. The basic principle is discussed first, before all the key terms such as kV and rpm/V, operating voltage, load and idle current, torque, turns, electrical and mechanical power, losses, efficiency, etc. are explained. A brushless motor can't work without a brushless controller, it requires a three-phase AC voltage. To increase the speed properly, the controller must have information on the rotor position. This can be done by Hall sensors or directly via the motor windings. All that will be taken into account in the book.
Radio Control with 2.4 GHz
In the first years of the new millennium, in the development of radio control technology with 2.4 GHz, a real revolution has taken place. While the frequencies in the MHz range were standard over many years in model construction, a large proportion of modern communication technology and with it radio control (RC) has since taken the band between 2.4 GHz and 2.48 GHz. Contents: Components of a radio control - Properties of 2.4 GHz waves - Antennas - Modulation and data transmission methods - User interface and programming - Telemetry - Assembly and initial operation
