Drones and Cognitive Dissonance [PDF]
, 2013 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.

Parametric Optimization of a Cyclogiro Aircraft Design for Efficient Hover with Aeroelastic Considerations [PDF]
Journal of Applied and Computational Mechanics, 2021 A minimization procedure is proposed to orient the design of a vertical take-off and landing drone towards sustainability. The vehicle is a novel cycloidal rotor drone and the principal objective is to yield the best ratio of payload to power consumption.

Electric Rocket Launcher Aircraft—Drone-Launched Short Range Rocket System
Aerospace, 2023 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.

A Small Gas Turbine for Drone Aircraft: Design Philosophy [PDF]
Volume 2: Aircraft Engine; Marine; Microturbines and Small Turbomachinery, 1990 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
Journal of Conflict Resolution, 2022 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.
