This paper presents explicit analytical solutions of the pressure coefficient and the pressure ratio across the
oblique shock and expansion waves in function of the flow deflection angle. These new explicit pressure-deflection
solutions can be efficiently used in solving applied aerodynamic problems in supersonic flows, such as the aerodynamics
of airfoils and wings in supersonic-hypersonic flows and the shock and expansion waves interactions, and can be also
used to increase the computational efficiency of the numerical methods based on the Riemann problem solution requiring
the pressure-deflection solution of the oblique shock and expansion waves, such as the Godunov method.
