Unfortunately, there are many airplane crashes in the world every year.

From its inception, the main goal of aviation is flight safety and preservation of passenger life. I decided to connect my life with aviation, that’s why I became a cadet of Belarusian State Academy of Aviation, and I want to make the contribution to the development of this industry.

Everyone knows that the main value in life – is life itself. For this reason, I decided to connect my proposal with the safety of flights.

The subject of this project is a bracelet, which is put on the passenger's hand during check-in and removed at the end of the flight. To prevent unforeseen situations the bracelet is fastened ...

Earth exerts a gravitational force and pulls down every object that attempts to leave or escape it. Therefore, in order to break free from Earth’s gravitational pull, it is essential for a rocket to attain an enormously high speed. This velocity is known as the ‘escape velocity’. For Earth, the escape velocity value is 11.2 kilometers per second (25,020 mph); this means that you have to accelerate a rocket at 11.2 kilometers per second in order to make the orbit.

This project is about building a mechanism that uses gravitational force to launch space shuttles instead of against it to achieve the escape velocity with lower cost. This is done by integrating roller coaster principle, Newton law and existing ...

Just like the earth, space has garbage too. The junk or garbage are called Space debris. Right now some tens of millions of pieces of space junk are circling our planet—broken satellites, rocket parts, and other human-made materials trapped in orbit. For many reasons removing those debris has become very difficult. The number of debris made it very difficult to be removed.

This project provide alternative solution to this problem. The project objective is managing space junk that are becoming problem to space exploration by directing the space debris from earth's orbit to the sun's path. Researches has shown that The recent uptick in solar flares and other activity on the sun could one day cripple satellites or knock ...

Many peoples travel through jungles and cross a river for many reasons, like for research and hiking and many others. While doing so, many peoples get attacked by wildlife when passing by because peoples are not aware of which animals are nearby. Animal attacks have been identified as a major public health problem. "Unprovoked attacks occur when the animal approaches and attacks a person(s) who is the principle attractant, for example, predation on humans. In 1997, it was estimated that up to 2 million animal bites occur each year in the United States. Injuries caused by animal attacks result in thousands of fatalities worldwide every year. Some of the world's deadliest animals include mosquitoes.which are estimated to kill about ...

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 trough 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 ...

We present in this opportunity a 6 passenger full eVTOL aircraft concept for Urban transportation, with vertical propulsion electrical engines and propellers in under the fuselage arranged configuration with air intake. Also will have engines on the sides of the fuselage for horizontal propulsión.

My company: GRUG GROUP LLC, was founded to supply services in the aviation sector and to develop a variety of future aircraft. We currently are working on several eVTOL flying vehicles concepts. Those are designed with different characteristic and capacities to fit a wide range of the demand that could be in the future.

The projected global market for urban passenger flying vehicles will be of 21 billion US dollars for the year 2035. Other ...

This device uses GPS and a terrain/obstacle database to create a predicted flight path. When the predicted flight path detects an approaching CFIT threat, the device changes from a passive flight following mode, gives the pilot an aural warning and a visual threat display. The pilot gets a 3D visual picture of where the predicted flight path will hit the terrain/obstacle. By maneuvering the airplane, the pilot can alter the predicted flight path away from the terrain/obstacle. When the predicted flight path no longer detects a CFIT threat, the system returns to the passive mode.

What makes this system novel is that when a CFIT threat occurs, it shows the pilot a visual picture of the predicted flight path ...

Prior to AC all-magnet motors were used for some four decades then forgotten, perhaps from ferrites of the day too weak to be very practical while today with cobalts they are far stronger and last at 90% full power >>700-years.

A recent 1-Megawatt all-magnet generator was developed to have 'no spark', for security to provide power in with explosives and isolated from external needs, has a 50-year, 100%-Continuous Duty-cycle output guarantee with normal service.

A specific design for the Astrobotic M-1 Lander, became a novel geometry of all-magnet motors for electricity of 2.6kw, 110vdc, 24A, 18cm x 7.6cm in diameter replacing a 542w solar panel for use in space.

An advantage for in-transit being aiming with reactors no fuel, allows lunar night ...

Innovative cycles in the emergence of fundamentally new types of gyroscopes last for a period of forty to fifty years, and the change from one to another occurs only after a serious breakthrough in physics and technology. Gyros can measure the course of a scientific revolution.

Today offered a fundamentally new type of power astatic gyroscope. The spherical rotor with magnets makes forced coherent oscillations around in a vacuum cavity of a stator with solenoids under computer control. The device can decide the problems of converting vacuum energy into electrical energy and generating entropic forces for move objects in space and on Earth (not a reactive way).

Good news - unusual gyroscope is already working!

The extremely simple formula ...

Contrary to logic and general theory, a bullet with a flat tip moves in water several times faster than a bullet with a sharp tip. This effect is simply explained: a flat tip creates cavitation bubbles that rub on the rest of the bullet surface very slightly. That is, the total area of friction is reduced so much that it fully compensates for the enormous resistance of the flat tip.

Is it possible to achieve this effect in aerodynamics? Everyone says no, since cavitation is only a property of the fluid. But even in the '30s, it was proven that at high speeds the gas has fluid dynamics. Just this discovery allowed to improve cooling technology.
But what configuration ...
