Ultra-lightweight vehicles are being developed to provide a number of high tech, long duration functions during flight. Applications including: military, weather, shipping, safety, commercial, border control, etc. applications. These vehicles typically are large, fragile, solar powered aircraft operating at between 50,000 and 90,000 feet for days to months timeframes.They typically have solar panels on the top of the wings and banks of batteries to store energy for night time operation. Usually > 50% of the vehicle weight is for batteries alone.

This approach provides a way to secondarily charge the batteries, along with significantly (40 to 60%) reducing the weight of storage batteries required for operation. Additional optical panels, designed for specific wavelengths (with up to >80% conversion efficiencies) ...

Design Statement:
Design of this transport system consists of the following main parts.
1. Main vehicle/ engine with electric or fuel powered thrust engines, fold-able wings. To move or run the vehicle on road surface or track surface four powered wheels are there in the vehicle.
2. Frame to place the air-foiled shape cabin or bogies.
3. Airfoil shaped cabins to carry passengers and payload with glass front cover and solar panels at roof as per option. Landing wheels are there in each boggy or cabin to allow them to move or run over the road or track surface.
4. Rotary seats inside the airfoil shaped bogies or cabins. Outed tube or body of seat mechanism is worked as ...

For 30 years lean combustion has been known to lower NOx emissions and many programs outline its benefit and in its Tapps II Combusor final report submitted by GE for its GEnx Engine in 2013 it shows zero fractal components. If things are the same, a small but important change can be made. It was shown that fractal grids can increase turbulence by over 100% and higher (Geipel et al 2010). In the recent book “Fractal Flow Design: How to Design Bespoke Turbulence and Why” Springer 2016. Editors Yaschiko Sakai and Christos Vassilicos outlined a series of studies that show bespoke or “customized” turbulence is now possible and can play an important role in Lean Combustion.

Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band signals have large EM wavelengths that can penetrate the plasma sheath layer with minimal loss, which is one of the well-known solutions in the community. However, conventional antennas rely on EM wave resonance, and therefore typically have a size of more than one-tenth of the EM wavelength, which is 10 to 100 km long at VLF band. Therefore, even an electrically small VLF antenna would have huge dimensions and enormous power consumption, which is impractical to ...

With all the new systems on the Space Center and other areas coming on line I feel this will be very useful. Most systems engineers and technicians use laptops or at least paperwork orders to operate, calibrate, and do maintenance on systems. Most often there is no surface to use the laptop or do paperwork. This item gives the user a work surface for either the 6 X 6 enclosure or the 24” type rack. A slightly smaller one can be made for the 19” rack. No tools necessary for installation it simply drops into place. You could logically locate a cabinet / box with an adequate amount of plates to support the area in need. If a system ...

Typical AR style rifles have a round or hexagon shaped tube that wraps around the barrel to protect the operator from the heat of the barrel during firing while simultaneously providing a location to mount additional accessories which facilitate the operation of the rifle such as lighting, aiming, etc. On most AR style rifle handguards, accessories are restricted to being mounted in four locations evenly staggered around the circumference of the handguard. An additional problem with the accessory rails that exist on the market is their inability to mount accessories directly beside one another, outside of the cardinal positions of 12 o’clock, 3 o’clock, 6 o’clock and 9 o’clock positions. This cylindrical handguard would enable the operator to mount ...

We as a team have designed a product named the Hovering Soldier to solve one of the important security challenges faced by the soldiers at the borders to protect one’s own territory and at the same time for the internal stability of the nation.

The Hovering Soldier is designed like a bird that flies towards the neighboring territory to monitor a particular area. It uses 2 types of cameras fit inside the bird’s eye. One is about 4MP sCMOS camera providing very high resolution in full sunlight. The other eye has a thermal camera named The Viento-G that is specially designed for a wide range of thermal monitoring applications This could also serve as an important tool to keep ...

Wings in Figure are in tandem configuration to have the capability of heavy payload applications due to efficient lift generation. Blended body fuselage and End plates are
configured with tandem wing, in order to acquire the low power consumption for long endurance by reducing the drag over the Unmanned Aerial Vehicle. Since blended body fuselage and end plates are configured with tandem wing, it was found that there is a lack of lateral stability in the mentioned new configuration with the tandem wings, end plates & blended body fuselage. To overcome that instability, twin tail with the dorsal fin is configured with tandem wing, blended fuselage and end plates. All together putting a novel configuration with low power consumption ...

Computational Fluid Dynamics (CFD) simulations have been performed over a blunt cone configuration with and without lateral sonic jet injected into hypersonic laminar flow at Mach 8.1. The comparison of pressure ratio indicates good match with the experimental results for no jet case. The simulation with sonic jet results in a complex flow field interactions like shock-boundary layer, shock-shock interactions, barrel shock, Mach disk, primary and secondary separations ahead of the jet etc.,. The comparison of pressure ratio indicates over-prediction of the plateau pressure rise and under prediction of the pressure rise due to the detached shock. The empirical estimates of separation distance, detached shock standoff distance, plateau pressure and jet penetration height matches well with the present CFD ...

The GFWIIITECH.TJID platform can be easily packaged, assembled, disassembled, unpacked and navigated in gravity, low gravity, or zero gravity by autonomous systems, remote systems, and human technicians. This platform is sturdy and functional while still being effective, efficient, lightweight, and simple. It is composed of carbon fiber centered set of composites with additive embedded conductive contact features. In addition, TJID mounts/shackles/unions will be smart enabled as well as having embedded conductive contact features. These will acknowledge contact pressure and continuity at the points of contact. The continuity sensor system will be carried through the entire TJID truss component for complete intelligent structure monitoring. GFWIIITECH.TJID is an innovation that is a functional development for spacecraft and gravity fields ...
