BACKGROUND Demands on unmanned aerial vehicles (UAVs) are continually and rapidly evolving, obviating simple modifications to existing platforms, particularly for increasing endurance of systems. The chief constraint on endurance of UAVs is onboard power capacity; the weight and space requirements of energy storage present an anathema to UAV flight...

Turbine-Driven, Shared-Rotor Generator

BACKGROUND Rapidly evolving unmanned aircraft system (UAS) requirements have necessitated the creation of novel methods to provide power to these craft in increasingly niche environments such as high altitudes or using more available heavy fuels to existing platforms to provide power to these craft, particularly with regards to turbogenerators. However,...

Acoustic Liners with Innovative Core Geometries for Enhanced Low-Frequency Noise Mitigation

BACKGROUND Low-frequency (<~400 Hz) airborne noise has several detrimental effects ranging from exciting structural vibration modes (with potentially catastrophic results), reducing passenger comfort and payload integrity on commercial flights, restricting military mission capabilities, to contributing to noise pollution. Low-frequency noise is...

Coating, Layer, and Bulk Material for Extreme Thermal Protection

BACKGROUND High-temperature applications, such as rocket engine combustion output, can reach temperatures as high as 3,315 °C (6,000 °F). Enough heat to fuse a concrete surface, like a launch pad, into glass. Fused concrete has a limited lifetime as structural integrity is compromised in some cases immediately, resulting in potentially dangerous...

Rotary Wing Aircraft Prototype with Gimbal Mount and Coaxial Motor

BACKGROUND Coaxial motor-powered designs need not be restricted to variable pitch rotors. The cyclic/collective pitch mixing system commonly employee three independent actuators to control the swashplate which can be an improvement on the separate systems found in large aircraft. However, variable pitch flight control systems create mechanical complexity...

All Terrain Land and Air Sphere (ATLAS)

BACKGROUND Demands on unmanned aerial systems (UAS) continuously evolve giving rise to design platforms with novel functionality. More and more UAS are asked to enter and navigate dangerous situations and damages structures to protect the lives first responders, researchers, and soldiers while aiding their mission. Some craft can land and roll on...

Turboelectric Power and Propulsion System for Unmanned Aircraft

BACKGROUND Current level of technology (LOT) multi-rotor unmanned aircraft (UAS) platforms is limited in range and endurance by the inherently low energy density of current LOT batteries. With more rigorous requirements being imposed by commercial, industrial, and defense users, the UAS market is leaning heavily on hybrid systems to fill this...

Sliding Weather Instrument Fixed to Tether (SWIFT)

BACKGROUND Kite Popper Line Climber is a manually deployed and uncontrollable sail. Kite popper can travel up the kite line to a stopping point (or bridle point) where the line connects to the kite, then “pop” closed and slide back down the line. The user needs to thread the kite through the popper, open its sail, and watch as the...
