Drone Launched Short Range Rockets
A concept of drone launched short range rockets (DLSRR) is presented. A drone or an aircraft rises DLSRR to a release altitude of up to 20 km. At the release altitude, the drone or an aircraft is moving at a velocity of up to 700 m/s and a steep angle of

Review of Patch Antennas used in Drone Applications
Drones are a form of remote-controlled aircraft that can take to the air without the need for a human pilot. An increasing number of people are looking into using drones for a variety of tasks, including but not limited to operations in hazardous areas ...

Electric Rocket Launcher Aircraft—Drone-Launched Short Range Rocket System
This paper is concerned with the idea of a significant improvement of state-of-the-art short-range rockets by means of using rocket artillery systems. Such a system consists of a rocket launcher aircraft (RLA) and a drone-launched short range rocket (DLSRR). An RLA is a reusable first stage of a military rocket.

Drones and Cognitive Dissonance [PDF]
There’s something about drones that makes sane people crazy. Is it those lean, futurist profiles? The activities drone technologies enable? Or perhaps it’s just the word itself–drone–a mindless, unpleasant, dissonant thrum.

A Small Gas Turbine for Drone Aircraft: Design Philosophy [PDF]
Low cost, and low weight, turbojet engines for RPV applications are being developed by the Aerospace Technical Centre in Brazil. A simple turbojet developing 320 N thrust is described which has been designed, manufactured and tested, succesfully matching its performance goals. Another turbojet developing 1000 N thrust has been designed and is currently

Wargame of Drones: Remotely Piloted Aircraft and Crisis Escalation
How do drones affect escalation dynamics? The emerging consensus from scholarship on drones highlights increased conflict initiation when drones allow decisionmakers to avoid the risks of deploying inhabited platforms, but far less attention has been paid to understanding how drones affect conflict escalation.

An Integrated Framework for Sensing Radio Frequency Spectrum Attacks on Medical Delivery Drones
Drone susceptibility to jamming or spoofing attacks of GPS, RF, Wi-Fi, and operator signals presents a danger to future medical delivery systems. A detection framework capable of sensing attacks on drones could provide the capability for active responses.
