Sustainable paint system for aircraft

The innovation can save about 10% energy in vehicles and can also be integrated into houses

Calculation of the energy savings that the innovation allows:

For a first approximation, a simply energy problem is solved: The power of solar radiation is completely transferred to the aerodynamic boundary layer.

parameters of the problem: v, P, I, S (Velocity of the body, Power consumed by the body, Solar intensity, Surface painted in matt black)

n: v, P, I, S (4); k: M, L, T (3)

Vaschy-Buckingham π theorem : n-k=4-3=1; η = I·S/P(v); I=1KW/m2

application to a car:

S=5 m2; P(100 Km/h)=40 KW; η = I·S/P(v)=1·5/40=12% energy saving
