This is a new design that takes advantage and merges two very well-known designs.

Airfoil wings make lift by changing the direction and pressure of the air that crashes into them as they move through the sky. The spinning cylinder wing design, using the magnus effect, has many advantages over traditional airfoils but also some disadvantages. This design is a type of merger of these two known technologies in such a way as to make use of the advantages of both while eliminating the disadvantages. Some of the advantages are: More wing lift and less drag!

Instead of the solid, rigid, stationary design of a traditional airfoil, the Magfoil has an outer skin that rotates. In other words, as ...

Invention pertains to the mitigation of Coriolis force in a system or apparatus using a novel method of rotation. The centrifuge is rotated in its primary direction at twice the target speed of rotation, while simultaneously rotating in the opposite direction, but at once the target speed. The combined effect is to reduce speed of rotation in the primary direction to once the target speed, whereas Coriolis force of equal strength is generated both to the right and to the left: The target speed of rotation is achieved in the primary direction, with remaining Coriolis force effectively zero.

This may be expressed where v is centrifuge’s combined speed of rotation (ω) in the primary direction (positive counter clockwise; negative ...

The principles used in a polywell fusion reactor can also be applied, and more readily, for an electron-positron antimatter collider/reactor. Polywell fusion reactors make use of the principle that electrons require much smaller magnetic energy density in order to be magnetically confined than more massive ions. However, this principle applies equally to positrons. Thus, the application of the polywell approach to electron-positron reactions instead of fusion reactions has the advantage, that all of the fuel particles can be effectively confined within the magnetic fields, and the electric fields don't have to contain an ion plasma. Furthermore, positron-electron reactions are orders of magnitude more likely than are fusion reactions among positive ions.

A polywell consists of a set of positively ...

In 1923 Professor Paul Biefeld and his student Thomas Townsend Brown discovered this effect during the test of a new type of capacitor. Basically the Biefeld Brown effect is electro gravitation. If you have a flat disk capacitor with a good dielectric like Barium Strontium Titanate (BaSrTiO3) and apply high voltage to the plates a directional force normal to the plates will be generated according to the formula developed by Doyle R. Buehler through experimental data.

F= 0,47 * U (J) = (force in Newtons)
Where U is the energy stored in the capacitor. The force generated will be proportional to the energy stored.
The energy stored is dependent of the capacitance and the voltage applied
The capacitance of ...

In space there is zero gravitational force and because of that astronauts cannot make fix to stay or stand on exact position compared to a gravity environment.


I want to suggest that this magnetic glove is not fully magnet as magnets attract iron on earth but magnetic glove use to stable body, any immediate movement or to stay in a position as they want to be stable.


In design suggest to magnets works in rounds of different circles that cannot attract each other and thumb is magnet free because if situation to move or pull hand thumb is work stable and help to glove pull hand off form any ...

Researchers have developed an integrated communications and control system for unmanned aircraft systems (UAS) that utilizes automatic dependent surveillance broadcast (ADS-B) technology. The system addresses safety concerns relating to UAS sharing airspace with traditional manned aircraft. This state-of-the-art system is capable of real-time situational awareness (e.g., air traffic, weather), updates in three-dimensional trajectories, and can be reengineered for specific mission operations and applications, giving the user a customized experience. The ADS-B system detects and tracks intruders; evaluates and prioritizes threats; declares and determines required action, and then communicates the determined action to the UAS pilot. The system’s ability to integrate various components for enhanced communications, command-and-control operations, and efficient sense-and-avoid capabilities addresses many of the technical barriers related to ...

Varuna is our first AUV and we completed it in a one year design cycle. The vehicle is fully modelled using Solidworks software and extensively we will simulate the structural and flow analysis with ANSYS, STARCCM+ software and going to manufacture almost entirely on our campus. Based on the Grid independent studies simulation is carried out for various speeds for 0.1-0.5 m/sec then only we can neglect the lift forces based on the wet test.

Varuna presents a cheaper, stronger, lighter in weight of 37 kg and compact size of 0.8m*0.6m*0.6mas length, width and height of the vehicle and capable of working under 50 m depth. New advancements include full vehicle control of six degrees of freedom, a dual-hull ...

Doesn’t the ever-expanding number of space launches to Earth orbit seem enormous every year? Statistics reveal fluctuating numbers between 80 and 90 per year starting from the 21st century. Leading countries compete with one another in order to lead the space industry by launching more and more spacecraft. Most of those satellites were launched for different purposes such as broadcasting, GPS services, weather forecasting, observation etc.

However, the main question is: “What happens to them after completing their missions?”. In the best case, their missions are extended for two or four years. Some of the little Low Earth Orbits burn in the atmosphere while falling, another part go to the unpopulated areas on the Earth or to the Pacific ...

NASA Langley Research Center has developed composite elastic skins for covering shape-changing (morphable) structures. These skins are intended especially for use on advanced aircraft that change shapes in order to assume different aerodynamic properties. Examples of aircraft shape changes include growth or shrinkage of bumps, conformal changes in wing planforms, cambers, twists, and bending of integrated leading and trailing-edge flaps. Prior to this invention, there was no way of providing smooth aerodynamic surfaces capable of large deflections while maintaining smoothness and sufficient rigidity.


Benefits

* Skin can be stretched exceeding 20% or otherwise warped with low actuation forces in one or both in-plane directions
* Increased comfort, flexibility and function for prosthetics
* Skin maintains sufficient smoothness and ...

Astronauts who spend long periods of time in weightless environments tend to suffer from loss of bone density and muscle mass. The intent of this idea is to reduce the degree to which astronauts experience these problems.

The idea is to sew elastic bands into coveralls in a way that provides a compressive force along the length of the body and the length of the arms. These loading stimuli simulate the force of gravity on a standing human body, causing the body to resist. This resistance, in conjunction with exercise and bisphosphonate supplementation, should help to maintain bone density.

The dashed lines represent where the elastic bands are sewn into the coveralls. They run along the front and rear ...
