We propose a blended wing-body delta aircraft of very high length-to-width ratio equipped with an upper-or-lower-surface-mounted turbo-jet engine-and-intake-plenum module which can be rotated laterally up to 90 degrees, swiveling from a pivot-point at the wing-body’s nominal center of pressure.
This vehicle will have fully-articulated chines with variable-dihedral and variable-slot capability. It will take off and land as an asymmetrical flying-wing-body, the “point” of the delta being one wing-tip, and the “tail” of the delta being the other wing-tip. In this configuration the engine module will be swiveled up to 90 degrees, exhausting past one of the chines, which in ...
Vertical Lift Aircraft Rotor Fault Detection is a process that uses rotor blade tracking revolution to revolution (rev-rev) data to identify faults and/or failures from the data stream.
Blade tracking takes data from the rotor system at very high speeds and typically averages the data stream to identify the relative blade height and lead lag for each blade. Dynamic blade motion and other fault indicators are encapsulated in the data and generally have been discarded and/or ignored through the averaging process. Blade track data sets are very complex and have been difficult to use for fault detection. ...
The Vision-Enhanced Situational Awareness (VESA) system is a situational awareness system for small general aviation aircraft that incorporates enhanced and synthetic vision, augmented reality, data fusion, and other technologies to provide a continuous display of the pilot’s surroundings fused with important flight information. The VESA system conceptual design was developed as a capstone design project of the Johns Hopkins University Master of Science in Systems Engineering Program.
The overarching objective of the design effort was to conceptually design the VESA system as a next generation situational awareness system for general aviation. Some supporting objectives of the project included the ...

The wave thread was developed to evenly distribute stress in nut/bolt connections. In the process it was made 16-20% stronger. This is because it is a threaded bullet shape and the stress is linear form the end of the bolt, not from the sides in a cylindrical bolts.
Threaded connections are everywhere; the properties of the wave thread will first be commercially applied to nuts and bolts. My software has engineer over 800 models; the output STL files have had over 100 3D printed; Over 60 Finite Element Analysis and one destructive test that pulled the heads of the ...
The development of the ZeeEye UAV provides environmentally friendly production and low-cost lightweight, durable proprietary CBM™ materials.
Technical Abstract: As UAV technology is rapidly evolving to meet specific operational requirements, the ZeeEye combines three high power and money saving technologies which provide the ZeeEye extended flight endurance.
The ZeeEye UAV and launch platform is easily transported by one person ‘backpack’ style. The ZeeEye UAV is stored in its container which doubles as its launch platform. The UAV doesn’t need to be removed from its transporter/launcher prior to launch, as both wings of the UAV rotate forward and ...
