“What are the main reasons of delay in construction projects in Iran and how does it affect the financial aspect of a project?”.
detach from one another at a certain location. This allows for the single pod to act like an autonomous car and can drive you directly to your doorstep. The rest of the pods re attach and travel to the next location where another single pod detaches. This would significantly increase the amount of space on busy streets and reduce congestion. These pods would ideally be run by electricity to reduce CO2 emissions. Air transport It is estimated that on average, there are 93000 daily flights. This means at any given time, there are in between 8000 and 13000 planes in the sky. These numbers are rising, and as a result, aerospace companies need to make planes more efficient and faster. Future airplanes will almost certainly use blended wings. The wings are formed into the shape of the plane and extend from the roof, instead of the current wings which are added parts onto the main body of the plane. This would reduce air drag, making the fuel more efficient and increasing speed. The plane would be able to lift more easily and potentially create less noise. It would also make much more space in the interior of the plane which would allow for more comfort whilst flying. Currently, Nasa are working alongside Boeing Phantom Works, to create a blended winged plane (image on the right). The consequence of this design is the removal of all windows, which would cause a claustrophobic and dark experience for the passengers. An answer to this is to lay real time, digital screens of the outside along the interior walls of the plane. This will give the passengers a greater sense of space and will provide light. In-flight bars and shops could also be made possible because of the large increase in space. Hybrid designs are achievable with new propulsion systems by using electricity, sourced from Lithium air batteries and superconductivity, to power a turbofan thrust. Superconducting motors would dramatically increase efficiency and decrease noise but super-cooled magnets are necessary to produce power. Blended wing-designs proposed by Boeing can break the sound barrier, whilst carrying a large amount of passengers. This solves the problem to the Concorde, potential of reaching super-sonic speeds but could only carry 100 passengers per flight, killing, its economic competitiveness.>GET ANSWER
