In the last three years, at least 173 people have been killed and more than 700 wounded in 17 ramming attacks around the world (source: http://www.latimes.com/nation/la-na-tsa-truck-warning-20170505-story.html).
Apart from being a tragedy on an individual level, the attacks also affect public life. The freedom to meet is a cornerstone in a civilized society.
A lot of (often temporary) anti-ram systems and safety barrier are now being installed. Most, if not all, of these systems are aesthetically unpleasing and their sole message is that there are crazy individuals in society!
The proposed "Sit-in" system has the same primary function as the ...
A surveillance device comprises a nest holding a secondary camera, and a drone holding a primary camera. Both cameras provide the operator with real time video or photos. While the secondary camera surveys the local field in which the nest is installed, the drone can be activated to survey a wider field or follow up certain events or persons using the primary camera.
The nest incubates the drone helping it maintain functionality by supplying power, control orders and data stream transfer. The nest is a moderator between the drone and the operator. The surveillance functionality of the ...

Aviation 100LL (100 octane, low-lead) gasoline is produced in relatively small quantities, contains lead, is expensive and difficult to obtain outside the developed world. Jet fuel is widely available, cheaper and has higher energy density than aviation gasoline. The turboprop or turbojet engine solutions with weight and reliability advantages over reciprocating engines, however, are too expensive for much of general aviation and the fuel burn is higher. For these reasons, considerable effort has been expended to develop jet fuel burning aviation diesel engines.
Propeller speeds in general aviation engines are generally below 2700 rpm. The standard spark ignition general ...

This concept presents a radically new wing design that aims to equip new aircraft designs such as flying car with the aim of emulating the behaviour of helicopters and tilt rotors with much higher efficiency, better performances and higher safety levels. The specific design has been grasped to allow producing typical manoeuvres including VTOL operations and hovering by means of a innovative and simple high-chamber ducted fan morphing wing with a dual configuration: one aims to increase lift by mean of Coanda effect and super circulation and the other aims to produce a vertical thrust by jet deviation. It ...

According to a NASA study published in 1999, there were 160,577 General Aviation aircraft of which 75% had fixed gear. These airplanes have the obvious drag penalty of the gear remaining in the airstream while in flight, and while substantial drag reductions have been achieved with aerodynamic fairings and “wheel pants,” there is still an inherent drag penalty from the hole at the bottom where the tire must protrude.
This hole, while necessary for safe flight operations, allows air to circulate in and throughout the wheel pant creating a significant amount of turbulence and ...
The eXOgon antenna is a broadband, circularly polarized, active, high frequency receiving antenna with switchable polarization sense. It has been known for decades that all ionospherically refracted radio signals are circularly polarized, but virtually nobody is taking advantage of this fact. The eXOgon antenna is a compact convenient antenna designed to receive either X or O mode circularly polarized signals in a frequency range between 5 and 60 ...
Reducing or eliminating Shockwave is of paramount importance to maximize Supersonic and Hypersonic flight efficiency. In order to reduce marginally the shock wave I have successfully developed a new concept after spending several years to research. The concept is described below.
To cancel shock wave move two metal piece in forward and backward direction in such a way that sound produced by both pieces cancel each other (the sound is out of phase with each other).
By changing the distance between two pieces you can cancel shock wave at variable or different speeds. Find the wave length of ...

DTI’s Next Generation Autostereoscopic Glasses-Free 3D LCD Displays Will Make Air Travel Safer
In the very near future, pilots will receive better information from DTI autostereoscopic instrumentation and navigation displays. According to NASA, this will result in an 18% improvement in pilot situational awareness.
In addition, aerial refueling operations will become faster and more efficient because refueling boom operators will be able to more easily position their booms into an aircraft fuel receptacle and air traffic controllers will have a better intuitive understanding and greater command of their airspace because they will see air traffic on their displays with high-fidelity depth ...
The proposed system represents a novel idea for efficient disposal of space debris present in Low Earth Orbit (LEO). Our system is designed to tackle space debris of the size in the range of 10cm. The main aim of this project is to deflect these medium sized space debris towards the Earth’s atmosphere which will itself serve as a medium for incineration of the debris.
The main body is a modified form of frustum of a cone. The inner surface of the cone is coated with a thick layer of Sorbothane, which is a synthetic visco-elastic urethane ...

This proposal closes the gap between old fashioned airplanes and new generation high tech super planes. Main focus is on utilizing affordable standard technique and the latest results from aerodynamic R&D. With this approach production and operating costs will be significant reduced.
For environmental aspects the engines will be designed as a single spool gas-turbine in combination with recuperated turbine technology.
Due to wing design and engine layout adaption to Hybrid and H2 fuel technology, this plane can play a key role in practicable green air ...
