1. New Physics Laws (SEMS) and Structural Elastic Curve
In an aircraft, by the Structural Elasticity Measurement System (SEMS) we can know in real time the weight
of the total load of such aircraft, its distribution, its variation by fuel consumption, and consequently we can
know the exact flight elastic envelope (FEE) of the aircraft. Considering the thousands of flight hours per
year of a commercial aircraft, it is obvious to think that any variation in the distribution of weight on an
aircraft, for minimal that may be, will always have a significant influence on the fatigue of the structure, and
therefore in the aging and consequent life-cycle.
On the other hand, at high speeds, any variation in the structural elasticity by minimal it may be, will always
have an aerodynamical influence which will affect the fuel consumption. Given the thousands of flying
hours per year of an aircraft, it is obvious that the accurate knowledge of the flight elastic envelope (FEE)
will be vital for the exact configuration of the aircraft’s flight control in real time, considering also the fuel
consumption and the weather conditions variations, all of which will result in a greater safety in the use of
that aircraft. The combination of the fuselage’s EE with the wing’s EE (including stabilizer and rudder), will
allow an exact integral control of the aircraft during all the maneuvers, and the maximum performance at
cruising speed.
The following drawings shows a hypothetical example of the use of the system based on the elastic
envelope (EE) of the fuselage, where we divide the fuselage into three sections (Fig. 1) and we suppose
that the center section is rigid. The Fig. 2 represents the loaded plane on track, which will allow us to
predetermine the exact flight elastic envelope (FEE) before take-off. Fig. 3 represents a hypothetical flight
elastic envelope (FEE) at cruising speed.
The curves drawings are exaggerated for illustrative purpose.
