Very Heavy Air Cargo
- competitor to ocean container shipping

        The Goal is to provide the lowest cost per ton / mile of cargo transportation.
       I hope the proposed ConcordLift ™ leads to a major reduction in transportation cost world wide also with the increase in speed. If this design is not adopted, I hope the proposal leads to a more cost effective alternative. 
      Aircraft engineers (of which I am not) design the aircraft to meet the required specifications. They balance a number of intersecting and competing issues.
       A certain amount of power is needed to provide lift and it is in a linear relationship. The heavier the weight proportionately the greater the power. There is no inherent advantage in building either small or large aircraft as far as the power needed to provide lift for the load. ( It is not quite so simple but in general twice the load to lift needs twice the power.)
      The power required for lift is in general separate from the power needed for speed.
      The power needed for speed has a geometric increase in the power needed ( again it is not quite so simple but in general twice the speed needs the square ie 4 times the power.) Since going faster means it will take less time for the engine to use fuel, the fuel used does not increase at the same rate. Slower is lower fuel cost. 
There is a relationship between size and construction cost. Other things being equal increase in cost is rises slower than increase in size. There is an advantage in going larger. Runways are 150 ft. wide. The standard for terminals is an 80 meter box, length and width.
        The cost to build is affected by speed and altitude. Slow speed, low wing loading, unpressurized is less costly to build. However slower means larger wings for the same load so larger wings increase cost.
       Altitude and cost are not so simple. Higher requires faster since the air is less dense. However the same speed at high altitude does not need as much power for the same reason. The 747 could never go so far at low altitude.
      The design constraint in this version was 20 lb. square foot of wing load for very slow speed. Engineering studies may find a higher wing load, higher take off and cruise speeds better. It is possible to design Concordlift ™ for high speed, high altitude, high wing load. I have versions like that for cargo and very high capacity, 1400, passenger use. They might have an acceptable cost per ton mile.
