Countering Malicious Drones


Today, the U.S. Senate Committee on Homeland Security and Governmental Affairs will hold a hearing on S. 2836, the Preventing Emerging Threats Act of 2018: Countering Malicious Drones.

The proposed Act would grant the Department of Justice and the Department of Homeland Security broad powers to deal with drones that are thought to pose a security risk.

The Act would allow the departments to track, take over, or take down drones.  Specifically, it grants authority to:

“(A) Detect, identify, monitor, and track the unmanned aircraft system or unmanned aircraft, without prior consent, including by means of intercept or other access of a wire communication, an oral communication, or an electronic communication used to control the unmanned aircraft system or unmanned aircraft.

“(B) Warn the operator of the unmanned aircraft system or unmanned aircraft, including by passive or active, and direct or indirect physical, electronic, radio, and electromagnetic means.

“(C) Disrupt control of the unmanned aircraft system or unmanned aircraft, without prior consent, including by disabling the unmanned aircraft system or unmanned aircraft by intercepting, interfering, or causing interference with wire, oral, electronic, or radio communications used to control the unmanned aircraft system or unmanned aircraft.

“(D) Seize or exercise control of the unmanned aircraft system or unmanned aircraft.

“(E) Seize or otherwise confiscate the unmanned aircraft system or unmanned aircraft.

“(F) Use reasonable force to disable, damage, or destroy the unmanned aircraft system or unmanned aircraft.

Airbus takes off towards a future of autonomous unmanned aircrafts


In February 2018, AirbusSkyways parcel delivery drone successfully completed its first flight demonstration in Singapore, while prototyping for the Quadcruiser to deliver heavier loads such as medical supplies is also underway.

PolyJet technology for manufacturing wind tunnel test models


This paper presents industrial applications of the Rapid Prototyping (RP) / Rapid Manufacturing (RM) techniques, developed at the Industrial Innovative Technologies Laboratory (Manufacturing Engineering Department from Transilvania University of Braşov) within the PLADETINO (Platform for Innovative Technological Development) interdisciplinary platform.

The purpose of this work is to demonstrate that Additive Manufacturing Technologies (AMT) can be effectively applied for fabricating test models used in aerodynamic experimental investigations. One of the most popular AMT used worldwide is 3D printing (3DP). 3D printing technologies can be divided in the following groups: inkjet printing, fused deposition modelling and polyjet. The present work is focused on applications of polyjet technology for manufacturing wind tunnel test models.

Cloud-Based Automated Design and Additive Manufacturing: A Usage Data-Enabled Paradigm Shift


Integration of sensors into various kinds of products and machines provides access to in-depth usage information as basis for product optimization.

Presently, this large potential for more user-friendly and efficient products is not being realized because (a) sensor integration and thus usage information is not available on a large scale and (b) product optimization requires considerable efforts in terms of manpower and adaptation of production equipment.

However, with the advent of cloud-based services and highly flexible Additive Manufacturing techniques, these obstacles are currently crumbling away at rapid pace. The present study explores the state of the art in gathering and evaluating product usage and life cycle data, additive manufacturing and sensor integration, automated design and cloud-based services in manufacturing.

By joining and extrapolating development trends in these areas, it delimits the foundations of a manufacturing concept that will allow continuous and economically viable product optimization on a general, user group or individual user level. This projection is checked against three different application scenarios, each of which stresses different aspects of the underlying holistic concept.

The following discussion identifies critical issues and research needs by adopting the relevant stakeholder perspectives.

Additive Manufacturing in UAVs: Challenges and potential


UAVs are gaining popularity due to their application in military, private and public sector, especially being attractive for fields where human operator is not required.

Light-weight UAVs are more desirable as they have better performance in terms of shorter take-off range and longer flight endurance. However, light weight structures with complex inner features are hard to fabricate using conventional manufacturing methods.

The ability to print complex inner structures directly without the need of a mould gives Additive Manufacturing (AM) an edge over conventional manufacturing. Recent development in composite and multi-material printing opens up new possibilities of printing lightweight structures and novel platforms like flapping wings with ease.

This paper explores the impact of Additive Manufacturing on aerodynamics, structures and materials used for UAVs. The review will discuss state-of-the-art AM technologies for UAVs through innovations in materials and structures and their advantages and limitations. The role of Additive Manufacturing to improve the performance of UAVs through smart material actuators and multi-functional structures will also be discussed.
