Such a big flying car would be big and heavy so need a lot of wing area, it means big and long wings to provide enough lift needed for flying. The wings aerodynamics lift center must be near the plane mass center, so wings must be not far from the middle of airplane body in practice. But how would we fold such a big wings that are in the middle of a car? I decided not to use one big wing, but make a biplane with the smaller wing span. Common biplane type is one wing above another, in this case they are more difficult to fold with its spatial structure, that's why I placed the wings in a ...
Problem: For all rotary wing devices, propellers, helicopter rotors, wind turbines, etc., there is an optimum twist to the blade for a given flow of air through the rotor disc. In most cases, the chosen twist is not optimum, and further, the use of rigid blades means that in variable flow conditions, gusts, the lift is not uniform.
Benefits: The rotor blade described here maintains a constant lift under all conditions, automatically compensating for gusts, adjusting the twist, even autorotating automatically.
Applications: For a tilt-rotor aircraft, the novel rotor allows high efficiency in hover, has increased twist when employed as a propeller, and can even reverse the twist for autorotation. In a conventional helicopter, a manual control of cyclic ...

We have chosen to utilize the vortex energy generated at airplane wingtips to generate electricity and power non critical parts of the flight, hence increasing the fuel efficiency.
It is an aspect of wingtip vortices, which has been studied very little in the past. The vortices have a high energy and this rotational movement of the vortices can be used to drive a turbine of propeller, which can in turn be used to drive a motor and feed into the electrical system of the aircraft.
With cost of fuel rising and aircraft manufacturers looking for various ways to improve efficiency of the aircraft such a device incorporated along with winglets can increase fuel savings by 7 to ...

The aircraft would open up under-served areas in the United States as well as countries that do not have infrastructure (runways, airports etc.).
A rendition and video of the aircraft is ...
Water tunnels have been traditionally used for flow-visualizations in aeronautical applications and more recently in bio-mechanical studies such as swimming of aquatic animals . Their use has been instrumental in understanding important aspects of fluid flows such as instabilities, vortex shedding, boundary layer stability and transition, and so on.
The water tunnel facility would be a work-horse for flow investigations in boundary layers, stability and transition, wakes, vortex shedding, jet-in-cross-shear-flows, flow over orographic models etc. The test-section size is planned to be 1.5 ft x 1.5 ft x 9 ft. While water channels have simpler construction, the flow speeds are limited due to the waves that develop on the free surface beyond speeds of the order of few ...

BZ200 is a novel, high-performance, thin, lightweight, polarization-insensitive, and wide-angle metamaterial RF absorber. It absorbs up to 99% of electromagnetic waves from 1 to 18 GHz (L to Ku band) as well as 35 and 94 GHz, without scatter. It is tailor made to order for applications of any dimension.
BZ200 enhances battlefield assets’ survivability and protection through reduction/modification of its Radar/IR signature. It has also been tailored for solutions for RFI/EMI, and EMC.
BZ200 can be retrofitted/integrated to conceal mobile/stationary land/marine vehicles and significantly reduce detection ranges with low-observable characteristics | Improve (E3) system interoperability by suppressing interferences | Shield personnel from RF radiation of active IED jamming equipment or active radar antennae during installations/diagnostics....
The single greatest barrier to escaping poverty in Africa is the lack of roads.
Over 600 million people, living on less than $1.25 per day, grow the food they eat and if possible they grow extra crops to pay for clothes, schooling, medical expenses and simple hardware such as hoes, buckets and cooking pots. The lack of decent roads, however, means these small-holder farmers pay as much as 75% of the revenue from these extra crops for transportation. Haulage costs for these low-income people can be 20 times greater than the costs in the United States.
Wings4Farmers intends to free people from poor roads with air freight services for their crops priced on par with road costs in the ...
Flight passengers having smart phone with WiFi can be identified and in-flight amenities serviced easily and quickly at seat level resolution (0.5m) with 90% accuracy. Instead of passenger pressing a call button and then flight attendant coming to the seat of the passenger to know the need and then going back to serve the need, the passenger can give the request using smart phone application and the flight attendant can serve the need directly. Apart from saving the valuable time of limited flight attendants, this will reduce the disturbance due to flight attendants walk for personal service on the space constrained aisle by 50%.
All available items and their details can be accessed and ordered using WiFi. Instead of ...
