Development, modeling and testing of a slow-burning solid rocket propulsion system
Small, unmanned aerial vehicles (UAVs) are expanding the capabilities of aircraft systems. However, a gap exists in the size and capability of aircraft: no aircraft smaller than 10 kilograms are capable of flight faster than 100 meters per second. A small, fast aircraft requires a propulsion system …

Development of low-thrust solid rocket motors for small, fast aircraft propulsion
Small, uncrewed aerial vehicles (UAVs) are expanding the capabilities of aircraft systems. However, a gap exists in the size and capability of aircraft: no small aircraft are capable of sustained fast flight. A small, fast aircraft requires a propulsion system which is both miniature and …

Design and Flight-Path Simulation of a Dynamic-Soaring UAV
… dynamic-soaring capable unmanned aerial vehicle (UAV) optimized for long-duration flight with no on-board power consumption. The UAV’s aerodynamic properties are captured with the integration of variable fidelity aerodynamic analyses. In addition to this, a 6 degree-of-freedom flight simulation …

An experimental study on the performance of existing and custom quiet propeller designs for unmanned aircraft systems
… can deter operations in populated areas. The UAS propulsion system is the dominate acoustic source, and there is a need to reduce the acoustic signature of the propeller-motor system without dramatically reducing propulsion system performance. Several propeller design techniques were considered …

The design of small propellers operating at low Reynolds numbers and associated experimental evaluation.
Small-scale Unmanned Aerial Systems (UASs) are becoming increasingly important in the field of intelligence, surveillance, and reconnaissance. As the desire for higher payloads and longer flight times increases, so does the need to optimize the performance of UAS components. It has been found that …
