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,...

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...
