3To deal with the ecological efficiency and speed requirements requested by the public, aeroplane manufactures have been forced to consider various major design changes.
One idea being developed which should help both flight range and fuel efficiency is using a single backward slopping boxed wing design with a tail or a double box-tail/wing design where the boxed wing also forms the planes tail. The boxed wing design is clever because it puts pressure on the back of the plane at the point where the boxed wing and tail meet. This increases the ‘lift to drag’ ratio. Drag is a common problem for all aircraft including both small planes (travelling in the high drag range of 70-400 Mi/h (112-644 Km/h)) as well as supersonic ones. This design is therefore important as it allows steeper take offs and landing and also increases fuel efficiency. Steeper take-offs and landing also result in less noise on the ground.
Yet another innovative design involves changing the type of engine and the positions of the engines from below to above the wings. More efficient engines save on fuel, and placing the engine above the wing allows the wing to act as a noise damper.
Demands for innovation and more efficiency have also been made in relation to airports.
Passengers don’t like losing 6 of a 10 hour trip, door-to-door, when the total flight time is only 4 hours. Those 6 hours are shared across a range of activities. 2-3 hours are typically spent at airports if all goes well. The other 3-4 hours are spent traveling to and from the airports. The two videos below show how these times could be reduced. Time at the airports is lost in check in, passport control, security checks, departure gate, loading and final take off. At landing, time it is lost while disembarking, passport control, baggage reclaim, and customs. Airbus’s solution of simultaneously loading and unloading passengers and their luggage as freight modules could significantly shorten a plane’s turn around time. This would be beneficial to both passengers and the airline.
Cordis’s solution of having multiple runways of different types in an airport also starts to solve the problem of multiple, simultaneous take offs and landing. The big passenger, cargo planes would use the long runways while the smaller PPlanes or STOLs could use a form of aircraft carrier sling shot for take off and landing thus also improving fuel consumption.
With the sudden wealth of new and varying designs -Vertical / Short Take Off and Landing (VTOLs, STOLs) and Personal Planes (PPlanes) accommodation has to be made for them too. If each town or suburb had a range of small air fields then people could park their planes at home in their garages and then need only to drive to the nearby field. Traffic flow to and from these landing fields would be similar to that of a big shopping mall or stadium inside a city.
