Since the 1950’s the state-of-the-art for transport aircraft design has been the extendable ‘tube’ that transfers strength and rigidity through the external skin. This design includes a passenger compartment with its ‘overhead bins’ and a floor under which cargo and utility equipment ride.
Hydrodynamically speaking, screw propellers of conventional marine propulsions represent vortex systems rotating in transverse to the flow plane that generates periodic impulses of pressure in water and this way create underwater acoustic field being used for detection and identification of ships.
The submersible speedboat can be carried assembled by road, rail or ship. The small size, high speed, the use of the water jet, low acoustic, electric, hydrodynamic, thermal and magnetic footprint, the silent planned displacement, with the propulsion system off and consecutive surfacing / diving,
This invention involves controlling the unwanted acoustic noise inherent in a highly concentrated flame by modulating an electric arc embedded in the flame. The purpose of the arc is to generate an inverse modulated signal, which will inhibit the unwanted noise, generated by the combustion gases in the flame.
Launch vehicle rocket engines must operate from sea level to near-vacuum conditions. They require high thrust at takeoff when the vehicle is heaviest. As the vehicle ascends to space it requires a high specific impulse (Isp) to minimize the propellant consumption. These requirements are in conflict.
The idea of reaching up to the heavens has captivated several generations. For this challenge, rockets have shown to be extremely inefficient, and the idea of constructing a “Centrifugally Extended Carbon Nano-Tube Tether Space Elevator” (CECNTTSE) presents unsolved technological challenges. We conclude that;
