Development of a 3D-printed device evaluating the aerodynamic performance of rotary wings


Applications for remotely operated rotary wing aerial vehicles, hereafter referred to as drones, are rapidly expanding in scope and such aircraft may soon become an integral part of everyday life as well as a source of innovation.

However, it is quite difficult to improve drone flight performance and reduce development costs because performance optimization depends strongly on the intended application.

As a result, drones are currently developed by trial and error using various rotary wing shapes. In this study, a device for evaluating the aerodynamic performance of rotary wings is proposed.

The authors consider it likely that the proposed device will be useful for various drone-related applications in addition to facilitating drone development because it is inexpensive to produce and can eliminate the need for large expensive laboratory equipment such as wind tunnels when performing flight characteristic evaluations.

Additive Manufacturing of Wind Sensors for UAVs


According to Fred Squire, Director of Sales and Marketing at FT Technologies, “The FT205 is the first in a new generation of lightweight ultrasonic wind sensors. The light weight of the FT205 together with the proven FT ACU-RES technology make it ideal for use on aerial UAVs and other applications where weight is critical.”


FT Technologies, a British company specializing in the development and production of ultrasonic wind sensors, has reportedly launched its first UAV-specific and 3D printed deviceFT TechnologiesFT205 is designed to aid UAV users in environmental projects and to execute more reliable flights.


Selective Laser Sintering (SLS) technology has been used to make the device, achieving a weight of just 100g. According to reports, the material used is a graphite and nylon composite. The device works in extreme environments, at a maximum altitude of 4.000 m and in temperatures between -20 and +70°C.


The FT205 sensor has been 3D printed by fellow British company Graphite Additive Manufacturing (Graphite AM) a specialist service bureau and consultancy firm. The FT205 uses acoustic resonance technology to deliver environmental information about the wind speed, direction and temperature, bases on minute vibrations in the device, and an in-built compass. A versatile piece of equipment, it can be plugged into an UAV’s input/output communications, mounted on a flat surface, or attached to a pole.
