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...
