N5 Sensors, Inc. of Rockville, MD is a University of Maryland spin-off commercializing a disruptive chip-scale gas sensor technology for industrial, environmental, and safety monitoring. N5’s microsensor arrays on a single chip could replace multiple conventional macro scale gas sensors used in portable multi-gas detector. These new sensors are small, accurate, low-power and capable of detecting multiple gases at the same time. Using the patent-pending sensing architecture, N5 is working to develop low-cost, ultra-compact multi-gas detectors which can be interfaced with mobile devices, allowing industrial workers, first-responders, and soldiers to assess the dangers of their surroundings rapidly and accurately in real-time using their smart phones or other mobile devices.

N5 has come up with a solution to demonstrate a ...

The idea developed focuses on power production to help produce an efficient system that helps reduce operation costs and also is green at the same time. The ideas employs modules that follow a certain principle to help produce electricity from heat. The heat used is that produced at the exhaust of the jet-engine. The temperature at the exhaust of the engine is between 850 C - 900 C.

According to the Seebeck principle, electricity is produced when there is a temperature difference across the module. The Peltier principle is the opposite of the Seebeck principle, where a temperature difference is produced on electricity being passed through it. They follow the principles of Seebeck effect and Peltier effect in the ...

The present invention in general relates to a vertical and short take-off and landing aircraft(V/STOL) comprising a novel adjustable multi-dimensional propeller that is capable of vertical take-off and includes a fuselage without control surfaces, apart from the present day conventional airplane. The rotors are embedded in the wings and are capable of independent orientation in 3 axes using a gyroscopic ...

Abstract:
Evacuation slides in airplanes are only used for evacuating people during an emergency situation. My idea is to use these slides to save people from an airplane crash as well as to identify the spot where the plane has crash landed.

About Evacuation Slides:

An evacuation slide is similar to a aircraft life jacket but just bigger in size. It is a 3 meter long canister of composed carbon-dioxide and nitrogen which delivers initial boost to the cylinder and the cylinder meter out the gas at 300psi the gases are forced the gas through a narrow gap which causes them to accelerate rapidly this acceleration creates a vacuum that then sucks enough ambiance air to inflate the ...

Problem Statement

Today most of the transportation systems are based on non-renewable energy resources and also calls global warning, air pollution, noise pollution in addition requires a specific path to travel. The most of power wastes into to overcome the frictional force, drag force etc. Till now no vehicle used gravitational force to push it into forward direction, so that can add additional forward force to vehicle or acceleration.
Aircraft flies against the gravitational force, so most of lift force or fuel wastes in form of no travel path or consumed on to overcome the gravitational and drag forces (or component of lift force is not primarily responsible for travel time). On the other hand, railway ...

This project started as a final thesis on aerospace engineering bachelor's degree. The objective was to create something that could be built with current technologies and promoted and motivated further development on electric vehicles.

Trasgo can achieve the same speed and manoeuvres as any internal combustion aerobatic aircraft. It aims at the aerobatics and competition sector for attractiveness and potential marketing use. Similar to how Formula 1 technology and advertising applies to normal cars.

This configuration mitigates the lack of power of current batteries by using several direct-drive propellers. This means extremely simple and cheap maintenance.

Propellers, motors, batteries and pilot are aligned with the line of flight to improve aerodynamics and manoeuvrability.

Visibility on the cabin is increased ...

“One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft's lift to power in hover or its efficiency during long-range flight.” DARPA

Triad Lift and Propulsion Design with Dynamic CG is a technology that will maintain an aircraft’s flight control while changing from rotor blade lift for vertical (helicopter) flight to wing supported flight for horizontal (airplane) flight, and back to vertical flight. This capability uses the advantages of both the helicopter to eliminate runways and of the airplane to capture high speed flight; all within in a single airframe. This action will occur by physically ...

The Triple Fuselage Flying Wing concept takes the idea of an aircraft built in the shape of one large wing to a new level. The idea of the triple fuselage is using multiple, in this case three, standard tube fuselages and building a flying wing body structure surrounding them. As seen in the illustration, the three fuselages would be positioned equidistant from the airplane's roll axis. This would ensure that while the plane is banking, the forces felt by the passengers would be similar to those felt in a traditional, single-fuselage aircraft. The point of this design is to avoid the placement of passengers far away from the roll axis of the aircraft, which to my knowledge occurs in ...

The aim of this project is to support search and rescue missions with gesture controlled swarms of aerial and ground based robots. Search and rescue operations in scenarios such as earthquakes, gas leaks and fire outbreaks today face some major challenges, the biggest of them being the time taken by the human rescue team to search and locate victims in the damaged area. This is caused due to limited human visibility and limitations of other human sensory organs in such situations. Another issue that slows things down is the possibility of presence of dangerous environments (like gas leaks) which become a threat for the human rescue team. This becomes even more inefficient if the search environment is a big ...

This proposes the use of unmanned aerial vehicles to aid in the detection and location of downed aircraft in a search and rescue scenario. Developments and innovations in the utilization of autonomous, coordinated UAVs to accomplish complicated missions provides an excellent opportunity to employ not only visual ground scanning capabilities but the ability to deploy airborne radio receivers to detect signals and perform triangulation calculations to quickly and efficiently locate radio signals emitted from emergency locator ...
